Why Compare Commercial Solar Quotes?
5-7 Year Payback
Commercial solar typically pays back in 5-7 years, helped by high daytime self-consumption and the economies of scale of a larger system.
100% First-Year Tax Relief
UK businesses can claim 100% tax relief on solar PV through the Annual Investment Allowance (AIA), up to £1,000,000 per year.
Designs Differ
Compare at least three commercial solar companies on price per kWp, completed commercial portfolio, MCS certification, G99/DNO experience and warranty.
Paid for Exports
Under the Smart Export Guarantee (SEG), businesses can sell surplus electricity to the grid at approximately 3-30p/kWh depending on supplier and tariff.
What Size System Does a Business Need?
Typical ranges by type of site. The right size depends on your roof and how much electricity you use during the day, which is what a quote works out.

|---|---|---|---|
| Small office / shop | 10-20 kWp | 25-50 | 50-100 m² |
| Restaurant / hotel | 20-50 kWp | 50-125 | 100-250 m² |
| Warehouse / factory | 50-200 kWp | 125-500 | 250-1,000 m² |
| Farm (dairy / tillage) | 30-100 kWp | 75-250 | 150-500 m² |
| School / community | 20-50 kWp | 50-125 | 100-250 m² |
| Large industrial / data centre | 200-1,000 kWp | 500-2,500 | 1,000-5,000 m² |
Commercial installations are subject to 20% VAT. See the commercial solar guide for costs, tax relief and planning.
Frequently Asked Questions
Answer a few questions about the site, who owns it and what you spend on electricity. We refer your enquiry to a small number of installers with commercial experience, and they contact you directly to survey the site and quote. We may also ask you some optional follow-up questions about the roof and electricity supply so the quotes are more accurate.
Yes. There is no charge and no obligation to accept any quote. The service is funded by installers, who pay us a referral fee only if you go ahead with them.
A typical commercial solar installation saves 30-50% on electricity bills. A 50 kWp system generating ~47,500 kWh/year can save £10,000-£15,000 annually at current commercial electricity rates (28p/kWh+). Additional income comes from exporting surplus at 3-30p/kWh through the Smart Export Guarantee (SEG).
UK businesses can claim 100% tax relief on solar PV through the Annual Investment Allowance (AIA), up to £1,000,000 per year, with a 50% first-year allowance available to companies beyond that limit. At the 25% corporation tax rate, this effectively reduces the system cost by 25%.
Yes, commercial solar installations are subject to 20% VAT (residential installations qualify for 0% VAT). However, VAT-registered businesses can reclaim the VAT through their normal VAT returns, making it effectively cost-neutral.
Yes, but you need written consent from your landlord. The business occupying the building and benefiting from the electricity generation typically arranges the installation. Ensure the lease terms cover the expected lifespan of the system.
The installation itself takes 3-5 days for a typical 50 kWp system, or 1-3 weeks for larger systems. The full process, from initial enquiry to generating electricity, takes 2-4 months including DNO (Distribution Network Operator) grid connection approval under G98/G99.
Commercial solar typically pays back in 5-7 years thanks to high daytime self-consumption, larger system economies of scale, and tax benefits. Businesses can claim 100% capital allowances (Annual Investment Allowance) on solar installations, effectively getting tax relief on the full cost.
