At The Commercial Solar Company, we’ve empowered countless UK businesses to slash energy costs and achieve net-zero 2050 goals with commercial solar panels. Despite the proven benefits of solar energy UK, myths about commercial solar persist, deterring SMEs, manufacturers, retailers, and agricultural businesses from switching to renewable energy solutions.
With UK energy prices at 20-25p/kWh in 2025 and growing pressure to meet sustainability targets, it’s time to clear up misconceptions. Below, we debunk the top five commercial solar myths and answer common questions to help you make informed decisions about commercial solar PV systems and unlock business solar benefits.
Myth 1: Solar is Too Expensive for Businesses
Many UK businesses assume commercial solar installations are cost-prohibitive. The truth? Solar PV systems deliver a business solar ROI of 16-45%, with payback in just 3-5 years. A 100kWp system saves £15,000-£25,000 annually by generating power at 4-6p/kWh compared to grid electricity at 20-25p/kWh.
The Annual Investment Allowance provides 100% tax relief on commercial solar installation costs, and Smart Export Guarantee payments of 5-15p/kWh for excess energy further reduce costs. At The Commercial Solar Company, we tailor solutions to maximise cost savings, making renewable energy affordable for businesses of all sizes.
Myth 2: Solar Panels Require Constant Maintenance
Another misconception is that solar panels demand frequent, costly upkeep. In reality, solar PV systems are low-maintenance, requiring only occasional cleaning and annual inspections.
Our modern monocrystalline panels are built to withstand UK weather, backed by 20-25-year warranties. At The Commercial Solar Company, we provide comprehensive support, ensuring your system delivers maximum renewable energy benefits with minimal effort, making solar energy UK a hassle-free investment.
Myth 3: Solar Only Works in Sunny Climates
Some UK businesses believe solar energy is ineffective in our cloudy climate. However, solar panels generate power from daylight, not just direct sunlight. Even in the UK, a 250kWp solar system offsets 64 tonnes of CO2 emissions annually, equivalent to planting 3,000 trees, supporting net-zero goals and boosting ESG credentials. Our team at The Commercial Solar Company designs systems optimised for UK conditions, ensuring consistent energy production and business solar benefits year-round.
Myth 4: Solar Installation Disrupts Business Operations
Concerns about downtime often deter businesses from adopting commercial solar. Most installations are completed in 4-12 weeks with minimal disruption. Rooftop solar panels typically qualify as permitted developments, requiring no planning permission for systems under 1MWp. Our experts at The Commercial Solar Company handle everything, from site surveys to Distribution Network Operator approvals for grid connection, ensuring a seamless process while keeping your operations running smoothly.
Myth 5: Solar Isn’t Suitable for All Businesses
Some believe solar PV systems are only viable for specific industries. Not true—solar is versatile enough for warehouses, retail stores, farms, and more. For example, a UK TV studio we worked with installed a 251.74kWp system, saving £46,679 annually and reducing CO2 emissions by 46,679kg yearly. From solar for home businesses and solar carports to large ground-mounted systems, The Commercial Solar Company customises solutions to deliver cost savings and sustainability for any business.
FAQs
Here are answers to additional questions UK businesses often ask about commercial solar, ensuring you have all the information needed to make a confident decision.
How long do commercial solar panels last?
Solar PV systems are built for durability, with a lifespan of 25-30 years. Our panels at The Commercial Solar Company come with 20-25-year performance warranties, ensuring long-term renewable energy savings and reliability for UK businesses.
What financing options are available for commercial solar?
Beyond the Annual Investment Allowance and Smart Export Guarantee, we offer flexible financing like Power Purchase Agreements (PPAs) and asset finance. These options reduce upfront solar installation costs, allowing businesses to pay over time while benefiting from immediate energy savings.
Can solar panels be paired with battery storage?
Yes, battery storage systems store excess solar energy for use during peak hours or at night, maximising cost savings and energy independence. At The Commercial Solar Company, we integrate battery solutions to enhance your renewable energy strategy and protect against energy price volatility.
Is solar viable for businesses leasing their premises?
Absolutely. For leased properties, we work with landlords and tenants to design solar PV systems that align with lease terms. Options like PPAs allow tenants to benefit from solar energy UK without owning the system, ensuring cost savings and ESG credentials.
How does solar integrate with EV charging for businesses?
Solar panels can power EV charging stations, reducing costs for businesses with vehicle fleets. A 100kWp system can support multiple charging points, aligning with net-zero goals. Our team at The Commercial Solar Company designs integrated solar and EV solutions for maximum efficiency.
