As energy prices continue to rise across the UK, more commercial property owners are turning to solar panels to reduce costs, improve sustainability and future proof their business. For many businesses, the most important question is simple: “What’s the return on investment (ROI)?”
At SolarTherm UK, we help commercial clients understand the real financial value of switching to solar. From installation costs to long-term savings, here’s everything you need to know about the ROI of commercial solar panel systems and why more South East businesses are making the move to renewable energy.
What Is ROI in Commercial Solar Energy?
ROI, or Return on Investment, measures how long it takes for the savings from your solar panel system to pay back the initial installation cost. In commercial solar energy, this includes reduced electricity bills, potential income from exporting surplus power to the National Grid and any available tax or government incentives.
For businesses with high energy consumption, such as warehouses, manufacturing facilities and office buildings, the ROI on solar panels can be achieved within just a few years. After the payback period, the energy your solar panels produces is essentially free, leading to decades of financial and environmental benefits.
Cost vs Long Term Savings for Commercial Solar Panels
While the upfront cost of a solar panel investment can be significant, the long term benefits far outweigh the initial investment. At SolarTherm UK we provide tailored solar solutions for commercial properties across the South East, helping businesses lower operational costs and overheads more predictable.
Commercial properties see up to a 70% reduction in electricity bills and are eligible for payment when exporting unused electricity back to the grid through the Smart Export Guarantee (SEG). By taking power back and generating your own free electricity, you are protecting your business’ future from the risk of energy price increases.
The typical payback period of a commercial solar panel installation is 3 to 7 years, depending on the system size, energy usage and site conditions. After the payback period the electricity you generate is essentially free and with solar panel lifespan being a minimum of 25 years with most producing efficiently for up to 40 years, that’s decades of pure profit in free electricity.
How Much Does a Commercial Solar Installation Cost?
The cost of installing commercial solar panels in the UK depends on several factors, including system size, available roof space and site access. On average a medium sized solar PV system starts at around £40,000 although this can vary depending on your building’s specifications and energy goals.
At SolarTherm UK, our engineers carry out a detailed energy assessment to design the most efficient solar system for your property, ensuring that you are earning the best ROI and performance over the system’s lifetime. All our quotes and performance estimates are validated by EPVS, the Energy Performance Validation Scheme, who ensure our figures are accurate and not over inflated.
Your dedicated Solar Expert can also assist with financing options, government backed incentives and advice on tax relief schemes. The SolarTherm UK aftercare team is also on hand for any questions or maintenance concerns you may have after installation.
Boosting ROI with Solar Battery Storage
Adding solar battery storage to your system can further enhance your return on investment. Solar batteries allow businesses to store excess solar energy and use it during peak demand or at night, minimising reliance on the National Grid and keeping energy costs lower.
SolarTherm UK offers advanced commercial battery systems designed to integrate seamlessly with your solar panels to give your business greater energy independence and more control over your power.
