The pitfalls of solar and BESS quotes: Why choosing the right energy partner matters
In the highly competitive world of commercial solar and Battery Energy Storage Systems (BESS), businesses may be tempted by the lure of the lowest quote. While cost-efficiency is important, it’s crucial to consider that solar energy is a long-term investment, and cutting corners today could result in significant complications in the future. At RenEnergy, we believe in engineering solutions that are built to last, using innovative technologies that deliver both immediate and future-proof results. Here, we break down key elements to look for in a solar quote and explain how selecting the right energy partner can make a lasting impact.
Not all quotes are created equal
The rapid growth in the demand for renewable energy has created a market where aggressive pricing strategies are common. Some companies and EPCs (Engineering, Procurement, and Construction) may quote low in order to secure projects, but at what cost? A cheap initial price may often mask subpar equipment, insufficient system designs and poor after-sales service. When assessing a solar quote, businesses need to look beyond the number at the bottom of the page and ask key questions about the quality of what’s being offered. Cutting costs in the design of electrical equipment poses a significant risk for investors, as it can lead to future failures and potential damage to critical infrastructure. Overlooking quality in the finer details often leads to costly, larger-scale issues down the line.
Common cost-cutting strategies: Beware of shortcuts
1. Inferior equipment
One of the easiest ways companies can lower costs is by using lower-quality solar panels, inverters and batteries. While these may work in the short term, they often lead to reduced efficiency and a shorter lifespan, requiring premature replacements. This can significantly affect your return on investment. Ensure that your quote specifies high-quality, durable equipment from reputable brands, with solid warranties attached.
2. Insufficient allowance for installation components
Apart from the major components of the system, have a look at all the additional items such as cable size and length, the quality and material that cable trays are made of, and whether mounting structures will be weather-proof. While these may seem like small items, having to remove an array due to poor initial mounting and having to re-install the system, is an inefficient use of resources. Short timelines for installation of this equipment will also take away the quality of the installation.
3. Inadequate system design
A well-designed solar and BESS installation is essential for maximising efficiency and future-proofing your energy needs. EPCs that quote aggressively may skimp on the design phase, offering cookie-cutter solutions that are not tailored to your specific energy profile. This could lead to undersized systems that fail to meet your needs. Understanding the landscape of the customer needs and requirements tailored with the correct solution will ensure that expectations are met and results are given.
4. Lack of future scalability
A solar system is a long-term asset. Your energy requirements will likely change over time, and the ability to scale your system or integrate it with new technologies is critical. Beware of solutions that do not consider scalability and are inflexible in their design.
5. Hidden costs
Sometimes the cheapest quote may not cover everything. Watch for hidden costs, such as additional charges for installation, maintenance or grid connection fees, electrical costs and lastly additional monitoring equipment. A comprehensive quote should be transparent about all costs involved in the project lifecycle.
Future-proofing your business with innovation and expertise
The success of a solar or BESS installation goes beyond the installation itself. It's about having the right partner who will be there to support you for the long haul. RenEnergy takes a holistic approach, ensuring that our systems are designed with your long-term energy goals in mind. We believe in transparency and engineering excellence, providing our clients with future-proof energy solutions that optimise efficiency, scalability and durability.
The energy landscape is constantly evolving. Technologies such as electric vehicles (EVs), smart grids and more advanced battery storage are already reshaping how businesses consume and manage energy. When you choose RenEnergy, you’re choosing an engineering-led partner with an eye on the future. Our experience in delivering integrated solar and BESS solutions for commercial clients ensures that we’re always one step ahead, ready to adapt your system to future needs.
Boeta Jordaan, RenEnergy Africa’s Technical Manager, notes: “The key to a successful solar project is not just in the installation, but in understanding the long-term vision. You need a partner that will stand by you, providing ongoing maintenance and upgrades as your business grows. That’s where the real value lies.” Tom Lloyd, RenEnergy’s Sales Director in the UK adds: “By choosing a partner such as RenEnergy, you’re not just investing in high-quality equipment and design, you’re investing in a relationship that will support your business’s growth for years to come.”
Pick a partner that’s already been evaluated and accredited
In 2023, RenEnergy was selected for acquisition by Aggreko, a global leader in energy solutions, following a rigorous due diligence process that confirmed the strength and quality of our engineering, operations and client relationships. This acquisition reflects our commitment to delivering world-class solar and BESS solutions. Moreover, our expertise has been recognised by leading financial institutions, with major financiers selecting us as one of just a few companies to collaborate with for renewable energy projects - reinforcing our position as a trusted and innovative partner in the commercial energy sector. In the UK and South Africa, RenEnergy belongs to industry bodies, hold multiple accreditations and have been selected as a trusted installer by key supply partners.
Invest in the future, not just the present
While it’s tempting to select the lowest quote, it’s essential to consider that solar energy is a long-term investment. A low upfront cost may result in ongoing headaches and expenses down the road. It's simple: Quality has a value - RenEnergy will not compromise, and your business should not either.
