Enter the number of parking spaces and your postcode and the page works out an indicative system size, capital cost range, annual generation and payback from the figures published on this site. It is an estimate, not a quote. Add your email afterwards if you want us to look at it with you; we reply by email.

Enter your spaces and postcode to see an indicative size, cost range, generation and payback.

Indicative only, not a quote. Assumes 1.7 kWp per space (see how the capacity is derived), £900–£1,400 per kWp installed (see the cost guide; the one published UK government illustration implies about £1,000 per kWp), PVGIS 5.3 yield for the nearest reference city, 24p/kWh for power used on site and 12p/kWh for export, and Annual Investment Allowance relief at the 25% main rate for a profitable company. Ground conditions, the grid connection, planning and EV charging are not included.

Why we ask: postcode sets the yield, spaces set the size, and timing tells us how to prioritise a reply.

How this works: this is an independent information site, not an installer. Your enquiry comes to us and we reply by email. We do not run a lead auction, pass your details to installers or add you to a marketing list.
