Amid rising electricity tariffs and the need for sustainable energy solutions, South African businesses are increasingly turning to large-scale solar installations to reduce costs and secure operational reliability. By cutting dependency on the nation’s often unreliable grid and utilising innovative financing structures like Power Purchase Agreements (PPAs), businesses are setting themselves up for significant long-term savings. However, navigating the path to commercial solar adoption involves complex challenges that need careful planning and execution.
“Solar energy not only provides a resilient power solution but is also a business strategy for future-proofing against energy inflation and grid instability,” says Frank Rovelli, CEO of Probe. “Large-scale solar installations give firms the ability to stabilise energy costs, improve operational reliability, and align with sustainable practices. At Probe Group, through Probenergy, we are committed to helping businesses unlock this potential.”
Understanding the financial benefits of solar installations
For commercial operations, electricity is often one of the largest operational expenditures. A large-scale solar installation directly addresses this by reducing reliance on grid power. Businesses can generate their own electricity, offsetting a considerable chunk of their utility bills.
Rovelli cites an example of a manufacturing plant consuming 400,000 kWh of electricity per month at an average cost of R2.50 per kWh, totalling R1,000,000 per month. By investing in a rooftop solar array capable of generating 200,000 kWh per month, the business can potentially see savings in the region of R500,000 monthly if the system is performing optimally. Over a year, that’s R6,000,000 in direct cost reduction.
Additionally, solar installations often come with minimal ongoing expenses once the system is operational. Maintenance and performance monitoring typically cost a fraction compared to conventional energy bills, further enhancing return on investment (ROI).
Leveraging Power Purchase Agreements (PPAs)
One of the most significant barriers to solar adoption is the upfront capital required. Enter Power Purchase Agreements (PPAs) – a financing model that allows businesses to adopt solar energy without the capital burden. Under a PPA, a third-party provider funds the installation, operation, and maintenance of the system, while the business agrees to purchase the solar electricity generated at a pre-agreed rate, typically lower than traditional grid tariffs.
For example, imagine a commercial real estate developer installing a 1 MW solar system with a PPA. The developer agrees to purchase electricity at R2.50 per kWh under the PPA, compared to the R3.50 grid-tariff rate. If the solar system generates 120,000 kWh monthly, the business pays R216,000 instead of R300,000 for the same electricity. Over a typical 20-year PPA term, these savings compound substantially, totalling millions of rands.
PPAs also offer predictability. Rates are often locked-in, safeguarding businesses against future electricity price hikes. Additionally, businesses don’t bear the risks associated with system performance or maintenance as these are managed by the provider.
Challenges in commercial solar adoption
Although the financial and environmental gains are compelling, adopting commercial solar systems is not without its challenges. Here’s a closer look at the key obstacles:
Even with dropping prices in panel and energy storage technology, a significant initial investment is required for those opting to own the system outright. Installing a 1 MW solar farm can cost between R10 million and R13 million. While solutions like PPAs reduce financial barriers, businesses must carefully evaluate contract terms to ensure favourable conditions.
Commercial solar installations require compliance with local regulations around grid connectivity, installation permits, and certifications. The deadline to register systems without penalties in South Africa, March 2026, adds additional pressure for compliance. Non-compliance could result in fines.
The South African grid infrastructure was designed for centralised coal generation and struggles to accommodate the decentralised nature of solar. High solar penetration has already caused power quality issues in certain regions. Upgrading grid connections or investing in sophisticated energy management systems can escalate costs significantly.
Solar power depends on sunlight, making energy generation weather-dependent. Grid-tied solar further depends on the grid being operational, and with intermittent power due to outages, this is challenging. Technological advancements have improved energy storage solutions and large-scale battery setups can be essential to continue operation during outages or at night. Commercial battery systems can range from approximately R4,000 to R5,000 per kWh of storage capacity, making large-scale storage investments a consideration for firms reliant on consistent power.
Strategies for successful adoption
To mitigate these challenges, businesses should adopt a phased and strategic approach to solar integration:
An energy audit offers insights into consumption patterns and peak periods, helping to right-size the solar system as well as achieve energy efficiencies. For instance, if a firm’s peak demand occurs during evenings, complementing solar generation with battery storage becomes critical.
Leverage government tax rebates, feed-in tariffs for grid-exported energy, and international green loans to reduce initial costs. Many businesses in South Africa have benefited from tax rebates on installation costs, significantly improving affordability.
Navigating the regulatory landscape and optimising system design requires expertise. Partnering with experienced solar providers like Probenergy ensures a seamless transition. From feasibility studies to ongoing maintenance, a robust partner can simplify complexities.
Combining solar with generators or wind turbines can enhance energy security, reduce storage needs, and maximise resource use. Hybrid systems offer a reliable power supply even during cloudy days or peak evening periods.
Long-term implications for businesses
Large-scale solar isn’t just about short-term cost savings; it’s a strategic investment in future-proofing businesses. Businesses adopting solar now position themselves as leaders in sustainability, appealing to eco-conscious consumers and investors. Additionally, generating on-site power reduces reliance on Eskom’s steadily rising tariffs, which are expected to increase sharply due to recent structural changes.
As Rovelli notes, “We are at an energy crossroads in South Africa. Businesses that adopt solar secure financial resilience and align themselves with global sustainability goals. At Probenergy, we see solar as a tool for empowering industries and driving national economic growth.”
Large-scale solar installations represent a powerful opportunity for South African businesses to combat rising energy costs, enhance sustainability, and gain energy independence. By leveraging financing models like PPAs, thoroughly planning system designs, and addressing challenges head-on, businesses can unlock the full potential of solar energy.
Probenergy, a trusted division of the Probe Group, plays a pivotal role in helping businesses achieve these goals. Whether you’re considering a full-scale solar farm or a hybrid solar-storage solution, Probenergy’s expertise ensures customised systems that meet your energy needs, while delivering maximum financial and environmental returns.
With climbing commercial energy costs and grid instability disrupting operations, South African businesses face mounting pressure to secure reliable, cost-effective power solutions. The answer lies not in little adjustments but in large-scale alternative energy strategies that match commercial demand. The shift to solar – and critically, to advanced energy storage systems – is fast becoming a strategic imperative.
The residential solar boom has proven South Africa’s appetite for energy independence, but commercial applications present an entirely different set of challenges, according to Frank Rovelli, CEO of Probe Group. “A manufacturing plant consuming 400,000 kWh monthly cannot simply install a few rooftop panels and call it sustainable. Large-scale commercial operations require integrated energy ecosystems that combine generation, storage, and intelligent energy management.”
The cost case is clear, explains Rovelli. As an example, a facility paying R2.50 per kWh for 200,000 kWh monthly faces electricity bills of R500,000. By offsetting that consumption through solar, the potential savings exceed R6 million annually, before factoring in rising tariffs or the costs of operational downtime.
Advanced energy storage for commercial systems
While grid-tied solar serves businesses well and reduces daytime electricity spend, many commercial businesses need hybrid systems to deal with frequent outages or to operate at night. This is where advanced energy storage is a gamechanger for commercial systems.
Battery storage is also transforming energy management by enabling businesses to implement load shifting and peak shaving as part of a holistic strategy, explains Rovelli. By analysing energy consumption patterns and tariffs, companies can optimise electricity usage to align with cheaper off-peak rates. Batteries store energy during these off-peak times and discharge it during peak periods when electricity is most expensive.
This approach reduces energy costs by minimising peak demand charges. “With the integration of data-driven precision, financial forecasting and tailored energy solutions, businesses gain actionable insights to streamline operations while enhancing cost-efficiency,” says Rovelli. “Effective battery storage supports smarter energy decisions and positions companies to lead in a dynamic and cost-sensitive energy market.”
Probenergy, Probe Group’s specialised alternative energy division, draws on over 60 years of expertise in battery technologies to deliver scalable energy solutions.
“Businesses need engineered energy ecosystems that deliver consistent power, not simply weather-dependent generation,” says Rovelli. “That’s where advanced battery storage becomes essential and where solid-state supercapacitors are changing the game.”
These new-generation batteries store energy electrostatically rather than electrochemically, enabling up to four times the power density of lithium-ion systems, in the same physical footprint. More importantly, they offer lifespans of over 20,000 cycles, with little degradation, fast charge/discharge capability, and no need for cooling systems.
“Solid-state supercapacitor modules offer 20,000 cycles, up to 43,000 cycles in some cases, with efficiency that remains above 90%,” explains Rovelli. “Compared to the 5,000–6,000-cycle lifespan of many lithium batteries, that’s genuine long-term value for commercial operations.”
Supercapacitors are also modular and futureproof. They can be connected in series with other battery types, allowing easy integration into evolving energy systems.
Financing: removing capital barriers
The biggest barrier to commercial solar adoption – high upfront costs – has largely been addressed through innovative financing models. Power Purchase Agreements (PPAs), rent-to-own solutions, and operational leases now allow businesses to access alternative energy systems without capital expenditure.
For instance, a commercial facility installing a 1MW solar system under a PPA might lock in electricity rates at R2.50 per kWh, well below current grid rates of R3.50 or higher. If the system generates 120,000 kWh monthly, that equates to R84,000 in immediate savings, compounding over the typical 20-year PPA lifespan.
These models also shield businesses from rising grid tariffs and transfer performance and maintenance risk to the service provider. “With the right financial partner, CapEx becomes manageable OpEx,” says Rovelli. “It’s about making best-in-class technology accessible.”
Start with an energy audit
In order to run as planned, accurate energy audits are the cornerstone of effective system design. Without them, businesses risk over- or under investing in infrastructure that doesn’t meet actual load profiles.
For industrial facilities, the Probenergy team uses tools like Tinytag loggers to monitor energy use over time, capturing insights into peak demand patterns and operational inefficiencies. These inform the engineering and battery storage requirements, especially if peak loads fall outside solar generation hours.
Grid integration and microgrids
Grid integration at scale also presents unique challenges. South Africa’s grid was not designed for decentralised power inputs, and poor integration can result in power quality issues. Experienced partners like Probenergy ensure compliance with grid codes and use advanced energy management systems to optimise energy flows and protect infrastructure.
Microgrids offer a reliable and efficient energy solution for large commercial properties, especially when integrated under a Power Purchase Agreement (PPA). “By generating, storing, and distributing energy locally, microgrids ensure uninterrupted power supply to critical infrastructure, even during grid outages,” says Rovelli. “This enhanced energy resilience safeguards essential operations while reducing dependence on centralised grids.”
Microgrids enable cost savings by stabilising energy costs through predictable PPA pricing, optimising energy use, and integrating renewable sources like solar, contributing to sustainability goals.
Containerised solutions: fast, flexible, scalable
Compact energy storage facilitates containerised energy innovations – and Probenergy provides fully integrated, modular systems designed for rapid deployment. It’s possible to deliver up to 8MWh of storage capacity in a 40-foot container, a solution that is ideally suited to remote sites or businesses that require fast, scalable installation without redesigning entire systems.
“Our containerised approach offers a rapid, flexible solution,” says Rovelli. “With modular systems, a client can be up and running very rapidly.”
Navigating compliance and incentives
South African businesses must navigate a complex regulatory environment, from municipal approvals to engineering sign-offs. Compliance with the Carbon Tax Act has also made renewable energy a financial, not just environmental, priority, reducing tax burdens while enhancing ESG credentials.
The Section 12B incentive allows 100% first-year depreciation for solar installations under 1MW, and accelerated depreciation over three years for systems over 1MW (50%, 30%, 20%). While some enhanced rebates have expired, significant savings remain available, particularly when energy storage is integrated as part of a full generation system.
Strategy first: how businesses are scaling smartly
But, adoption success depends on strategy. Many commercial clients start by targeting high-impact, low-complexity areas, such as warehouses with ample roof space and consistent daytime loads, before moving on to more complex installations like production facilities or multi-site operations, explains Rovelli.
“Phasing it in doesn’t mean thinking small,” notes Rovelli. “It means scaling smartly, matching your energy solution to your operation and future growth.”
Early adopters are already reaping benefits that go well beyond cost savings. Energy security becomes a competitive differentiator, particularly in manufacturing and processing industries. Predictable energy costs improve financial planning and sustainability credentials help attract conscious customers and unlock green financing.
“The businesses that move first aren’t just saving money – they’re building in resilience and unlocking growth opportunities,” says Rovelli.
The question facing commercial operators is no longer whether to adopt renewable energy, but how quickly they can implement systems. Those who act decisively will not only weather current energy challenges but position themselves for a bright, sustainable future.

Choosing the right battery for your vehicle is essential, especially as vehicles become more advanced and energy-reliant. Upgrading from a standard flooded battery to an EFB (Enhanced Flooded Battery) or AGM (Absorbent Glass Mat) battery could significantly enhance performance, reliability, and efficiency. But when is an upgrade necessary, and which battery type offers the best solution for your needs?
This guide will help you understand the benefits of these advanced batteries and when an upgrade would be worth it.
Ideal for start-stop systems
Idling in gridlocked traffic is a huge waste of petrol, and money. Very soon, almost all new cars will have environmentally-friendly stop-start technology. This brings down fuel consumption and harmful emissions by automatically stopping and starting the engine – reducing the time engines spend idling. Fuel savings from stop-start technology can be as high as 12 percent; the longer you sit, the more you gain.
An enormous amount of power is needed to ignite the engine. So, if you keep doing this over short bursts and in low-speed drives, such as when you’re sitting in a traffic jam, you need a heavy-duty performer. Automotive AGM and EFB batteries are an evolution of the lead-acid battery to deal with the extra power and thermal requirements in a stop-start environment.
Vehicles equipped with start-stop technology rely on frequent engine cycling, which puts strain on the battery. Both EFB and AGM batteries are specifically designed to handle these cycles, ensuring reliable performance and a longer lifespan. Using a conventional battery instead of an EFB in a stop-start system can cause battery failure within 2 to 4 months.
On average, EFB batteries have double the life-cycle of normal lead-acid batteries, while AGM batteries provide more than triple the life-cycle, making them a solid investment when you have to replace your battery.
Supporting high electrical demands:
Modern vehicles come equipped with a variety of electronic systems, such as infotainment units, heated seats, and advanced lighting. Both EFB and AGM batteries are built to support these power-intensive features, providing consistent energy and a longer lifespan.
Enhanced vibration and shock resistance:
AGM batteries offer superior resistance to shocks and vibrations, thanks to their unique design. The electrolyte is absorbed into glass mats rather than existing as a free liquid, allowing the mats to act as dampers between the lead plates. This compressed packing minimizes movement and vibrations to nearly zero, making these batteries exceptionally durable. For commercial vehicles, this level of reliability is an invaluable advantage.
Suitability for hot climates:
Heat can become a challenge for batteries, leading to faster degradation in many standard flooded types. EFB batteries, however, are designed to perform exceptionally well in high-temperature environments, offering better thermal stability and charge efficiency.
Handling long inactive periods or short trips:
If your vehicle is often left unused or used for short commutes, it’s likely the battery doesn’t fully recharge, leading to sulfation and other performance issues. AGM batteries stand out in these scenarios because they are resistant to sulfation and acid stratification. This resilience ensures better charging efficiency and retention, even with sporadic use.
EFB batteries also have a greater ability to withstand deeper discharge and operate effectively under lower states of charge than traditional lead-acid batteries.
Key differences between EFB and AGM batteries
Both EFB and AGM batteries represent significant improvements over conventional flooded batteries, but they differ in their technologies and applications. EFB batteries are a budget-friendly upgrade, offering better performance than standard flooded batteries, though they still share some of the same limitations. On the other hand, AGM batteries, with their non-liquid electrolyte, provide a range of advantages and are the top choice for those seeking a high-quality lead-acid battery.
Is upgrading worth it?
Upgrading to an EFB or AGM battery is a smart choice for vehicles with higher electrical demands, specific driving conditions, or start-stop technology. These batteries offer better performance, longevity, and reliability that align with the needs of today’s drivers.
Probe’s ranges of EFB and AGM batteries are designed to meet the varied demands of modern drivers. With Probe – you’re going to get high cycling performance, improved charge acceptance and a long service life. Whether you drive a start-stop vehicle in urban environments or need a power solution that can endure the extremes of heat and inactivity, Probe offers the perfect fit.

Selecting the right inverter is crucial when it comes to renewable energy installations, especially in a country like South Africa, where electricity issues present unique challenges. With frequent power outages, surges and an unstable grid, the choice of inverter can mean the difference between prolonged reliability and premature failure. Probenergy, a leader in the field, emphasises an holistic approach, leveraging deep knowledge of South African conditions to provide solutions that are effective and sustainable.
“The decision between inverters can be compared to choosing between a Porsche and a VW,” says Probenergy expert Grant van Houten. “While both are fundamentally robust, and designed in the same factories by the same engineers, the real question is about the level of functionality you need and will use, and fitness for purpose.”
Probenergy partners with renowned brands such as TBB, Victron Energy, Growatt, Deye and SunSynk, each offering distinct advantages tailored to local needs. TBB, for instance, provides robust inverter solutions well-suited for hybrid systems, ensuring seamless energy management. Victron Energy, known for its premium quality, offers inverter/chargers that integrate well into backup systems, providing excellent reliability even at a higher price point.
Growatt stands out for its cost-effectiveness without compromising on quality, making it an attractive option for budget-conscious consumers who still demand performance. Meanwhile, Sunsynk and Deye’s hybrid inverters balance solar energy use with grid power well, optimising efficiency and savings.
Understanding inverter technology
High-frequency inverters, known for their compact size and efficiency, use high-frequency switching transistors. However, these inverters often falter under South Africa’s erratic power conditions, as they have a limited tolerance for power surges and high starting currents from equipment such as pumps and compressors.
In contrast, low-frequency transformers are equipped with an iron core that acts as a buffer, absorbing power surges and protecting both the inverter and connected appliances. This enhances their reliability, making them suitable for the volatile South African energy environment.
Taking an holistic approach
Probenergy delivers solutions that are precisely engineered to withstand the local environment. “By focusing on the right technology rather than brand prestige, we ensure our customers receive the best value and longevity from their renewable energy systems. Our approach considers every aspect of the system, from the capacity to handle inductive loads to the inverter’s ability to handle power surges,” says van Houten.
Van Houten says while some inverters may perform well in stable electricity environments overseas, the local conditions in South Africa are more challenging. “It’s important to invest in durable, long-term inverter solutions that can cope with the challenges posed by our unique power landscape to get the best return on investment.”
While budget and brand often influence decision-making, the key is to focus on the technology that meets your specific needs. “With Probenergy’s comprehensive understanding and commitment to excellence, South Africans can enjoy reliable power solutions tailored to their environment, ensuring peace of mind and sustainable energy use for years to come,” says Van Houten.
South Africa has made significant strides with tax incentives encouraging businesses to invest in solar power. However, time is running out, as these incentives only apply to solar systems brought into use until 28 February 2025.
The Section 12B capital allowance presents a landmark opportunity for companies to cut operational costs while promoting sustainability, but they must act quickly to benefit, says Frank Rovelli of Probe Corporation. “With the deadline fast approaching, depending on the scale of the project, we advise that businesses start the implementation process with a solar solutions provider as soon as possible to be operational before March 2025.”
In a market mushrooming with solar installers ready to take advantage of the opportunity, Rovelli recommends that businesses turn to reputable providers that offer holistic solutions. “At this stage, it is even more critical for businesses to partner with an experienced solutions provider that can offer detailed energy audits and system design with a scaleable approach, advanced battery storage technologies and competitively priced Tier One products. Excellent ongoing maintenance, service and financing options should be part of the package.”
The power of Section 12B capital allowance
The Section 12B capital allowance enables companies to accelerate the depreciation of solar system costs, effectively allowing them to deduct 125% of the initial investment in the year the system is operational. This means that businesses will qualify for a cost plus 25% allowance on the cost incurred on renewable projects, in the year it was incurred.
“While the previous incentive allowed businesses to deduct the costs of qualifying investments over a one- or three-year period with particular thresholds, the expanded incentive enables businesses to reduce their taxable income by 125% of the cost of an investment in renewables in the first year, with no thresholds on generation capacity or the size of the projects that qualify,” explains Rovelli.
Rovelli says that a R1 million investment in alternative energy would qualify for a tax deduction of R1.25 million, in turn reducing the corporate income tax liability of a company by up to R337 500 in the first year of operation. “You’re effectively reducing the costs of your system by a third.”
Qualification requirements
To be eligible for the solar rebate under the new tax incentive scheme, businesses must be registered in South Africa, install a qualifying solar system for energy generation, ensure the system is operational by 1 March 2025 and adhere to regulations set by the South African Revenue Service and other authorities.
Only new and unused assets are eligible for this incentive, ensuring additional capacity beyond the business’s existing production. The assets must generate electricity from renewable energy sources such as photovoltaic solar energy, concentrated solar energy, wind power, hydropower, and biomass, including organic wastes, landfill gas, or plant material. Importantly, there are no limits on electricity generation for the duration of this temporary incentive, allowing businesses to scale their renewable energy initiatives without generation capacity constraints.
Because one of the eligibility criteria for this incentive is ownership of the qualifying assets, lessors that invest in qualifying assets that are leased to lessees under operating or finance lease arrangements will be able to benefit from the incentive, subject to other qualifying criteria. While the ownership may transfer from lessor to lessee in finance leases, this only happens at the end of the lease period, so the lessor would own the generation assets for the duration of this incentive.
Benefits of the solar tax incentive
Rovelli outlines several key benefits of the solar tax incentive. One of the primary advantages is cost recovery and enhanced return on investment (ROI). “By leveraging the accelerated depreciation allowance, businesses can more rapidly recoup their solar investment costs. This financial relief helps mitigate the upfront expenditure associated with solar installations, enabling companies to manage initial costs more effectively.
Another significant benefit is improved cash flow. “Businesses have the opportunity to deduct the full cost of solar systems in the year they are installed, which substantially lowers their taxable income. Reduced tax liabilities frees up capital that can be reinvested into other areas for growth and development.”
Consider your financing options
Although solar has become far more affordable, the initial capital outlay for a solar system can still be daunting for commercial users, Rovelli says. Probe has partnered with banks and funders to offer Rent-to-Own/Lease solutions, helping clients invest in their power.
“There are a few flexible financing solutions available, including subscription agreements and funding solutions designed for commercial installations offered through Probe’s financial partners. These solutions provide a feasible route to solar energy without requiring a hefty upfront payment.”
Taking a phased approach
Rovelli further advises that a phased approach is also a consideration to allow for a more manageable transition to solar power. “We work closely with clients to design a solar system that meets their current needs but can be easily upgraded in the future. It’s important to ensure systems are scalable, flexible and adaptable to changing energy requirements. We select the appropriate components to avoid compatibility issues in the future, and work with reputable brands to mitigate the risk that certain products may be discontinued. “
The broader impact
Adopting solar energy has far-reaching benefits beyond individual businesses. It contributes to diversifying the energy mix, reducing strain on the national grid, and fostering job creation in the renewable energy sector. By investing in solar, businesses are not just securing their future but are also playing a pivotal role in the nation’s clean energy transition.
“The new solar tax incentives in South Africa offer a golden opportunity for businesses to enhance their sustainability profile while achieving substantial economic benefits,” says Rovelli. “By taking advantage of these incentives and additional financial support, companies can transition to renewable energy in an affordable way.”

The solar energy landscape is rapidly evolving, with both residential and commercial sectors embracing renewable solutions to cut costs and enhance sustainability. However, a critical yet often overlooked step in this journey is the energy audit.
Corne Groenewald, Installations Manager at Probenergy, says an energy audit is the essential foundation of a successful solar installation. “If you’re investing in a system, take the guesswork and assumptions out of it. Having accurate data informs the size and scope of an optimal solar energy system, so you don’t end up having to spend more at a later stage. Detailed energy audits also assist in optimising energy efficiency and strategising energy usage.”
Residential installations
According to Groenewald, a simple checklist doesn’t cut it when it comes to an accurate view of energy usage. “When it comes to energy consumption, it is not solely about the amount of energy used, but also about the patterns of usage. I’ve seen multiple identical residential units have completely different energy consumption and peaks, depending on how they use power and their energy efficiency variables.”
The energy audit provides insights that help Probenergy’s engineers tailor systems to meet specific client objectives, says Groenewald. “A client may want solar energy with a 4-hour back-up. Through logging, we can see overall consumption as well as peaks. These peaks determine the size of the inverter. The back-up duration required determines the size of the battery.”
For residential customers, Probenergy uses the Emporia online logger for a full week. The logger connects to the customer’s WiFi to provide real-time energy usage data. This tool, capable of logging both single and three-phase houses, helps identify energy consumption patterns and peak usage times.
By breaking down the distribution board using up to 16 Current Transformers (CTs), the team can pinpoint which appliances or areas of usage are energy hogs, allowing for a tailored solar solution. The DB board can then be split into essentials and non-essentials. Bi-directional inverters, now required in the Western Cape, can feed energy back to the non-essentials or to the grid once essentials are covered. However, this requires the grid to be available, and doesn’t happen when operating on battery power. “While there are certain products that can shave the battery to push power to non-essentials, this depletes the battery very quickly,” Groenewald explains.
“The energy audit gives clients clear visibility into their energy data, allowing for better planning and usage,” says Groenewald. “For example, with a hybrid solar setup including an inverter and a battery, one can optimise energy consumption by allowing the battery to fully recharge during early solar hours (7 am to 11 am) and strategically scheduling heavy appliance usage after 11 am, maximising efficiency and reducing reliance on the grid during peak demand. “
Commercial installations
In the commercial realm, the approach differs with the use of Tinytag loggers. These devices are deployed to gather comprehensive data across large facilities, often requiring multiple loggers to capture the full energy profile. This rigorous data collection enables a detailed technical analysis, informing the engineering team with proper data to design for the full scope of the facility. Once the audit is complete, the data is meticulously analysed, culminating in a report that highlights inefficiencies and offers a proposal for a solar installation.
It is important to advise on energy efficiency upfront, indicating necessary changes like transitioning to LED lighting or optimising HVAC schedules, says Groenewald. “If changes are going to have a major impact on energy efficiency, we advise clients on this investment before we do the logging. For example, LED lights are 75% more efficient that traditional fluorescent lighting, so changing these throughout a factory can have a significant effect on energy consumption.”
Groenewald notes that industrial and commercial spaces frequently use substantial generators as part of primarily grid-tied systems. “Businesses want solar power to cut costs or to mitigate the limitations imposed by local councils,” Groenewald explains. “The common council constraint of a 1,000 kWh limit can lead to financial penalties for businesses that exceed this threshold, making it critical to optimise power systems.”
In this scenario, batteries can serve not only as a backup, but as a means to significantly reduce energy expenses. By integrating solar power with efficient energy management, these businesses can navigate regulatory challenges while achieving substantial savings. Overall, energy audits ensure that commercial solar installations are both cost-effective and efficient, supporting long-term sustainability and financial goals.
The increasing complexity and customisation of solar solutions makes energy audits invaluable. By accurately sizing the solar system based on detailed energy data, clients can avoid the pitfalls of under- or over-investing in solar infrastructure, and get the best return on investment.
