Install Solar Panels Cost is an independent guide to what solar panels cost, what they save and whether they are worth it for your home.
Why we exist
Solar is a big purchase, and most of the information about it is written by companies selling it. We set out to publish the figures plainly: what a system should cost, how long it takes to pay back, and when solar is not a good fit.
Who we are
We are a privately funded enterprise. We are not owned by an installer, a manufacturer or an energy supplier. Our guides are written and maintained by our editor.
How we work
- We show our sources. Every guide links to the official data it relies on, such as Ofgem, GOV.UK and MCS.
- We date our figures. Each guide shows when it was last updated and when its prices were checked.
- We show our working. Where a figure is our own calculation, we say so. See our methodology.
- We say when solar is not worth it. A north-facing or heavily shaded roof, or a poor export tariff, can make the numbers weak.
What we are not
We are not electricians, surveyors, or financial or legal advisers. Our guides are general information to help you ask better questions and compare quotes. Always get professional advice about your own home.
How we make money
If you request a quote from a qualified installer through this site, that installer may pay us a commission. It does not change what we write. Read how we make money.
