# Commercial solar savings calculator

This free calculator gives UK businesses an indicative estimate of what commercial solar could save through a Power Purchase Agreement (PPA). Enter your annual electricity spend to see estimated annual and 20-year savings, CO₂ avoided and the rough system size — from transparent, adjustable assumptions. It is a guide, not a quote.

## Frequently asked questions

**How accurate is the solar savings calculator?**

It gives an indicative estimate, not a quote. Your real savings depend on your roof, your electricity use through the day, the system size and your tariff. The calculator uses transparent, conservative assumptions you can adjust — for exact figures, request a free site-specific proposal.

**How does a solar PPA save money?**

Under a Power Purchase Agreement you pay nothing upfront and buy the solar electricity your system generates at a fixed rate guaranteed at least 30% below your grid price. You save on every unit of solar power you use on site, and the system is fully funded and maintained for you.

**What electricity spend makes commercial solar worthwhile?**

There is no hard threshold, but the more electricity you use during daylight hours, the more solar you use on site and the greater the saving. Businesses with a large daytime load — manufacturing, warehousing, cold storage, agriculture — tend to see the strongest returns.

**Is the calculator free and is there any obligation?**

Yes, the calculator is completely free and requires no sign-up. If you want exact, site-specific figures we can prepare a free, no-obligation proposal — but you are under no obligation to use the tool or to proceed.
