Solar Panel Advice Blog for UK Homeowners

Short, sourced posts for homeowners who hold a solar quote and want to understand it before they sign.

Written by the Solar Panel Price Check editorial team

This blog answers the questions people ask once a solar quote lands on the doormat. Each post focuses on one decision, such as roof direction, planning rules or what to check before you pay a deposit. We name our sources because you should be able to read the original advice yourself.

The posts sit alongside our main guides. The guides explain the big topics, while the blog goes deeper on single questions. Our solar panel cost guide sets the scene on pricing, and the post on scaffolding costs explains one line item that often surprises people.

What you will find here

Equipment posts help you compare what an installer proposes, since two quotes rarely match. Start with how many solar panels you need or whether a battery is worth it. Our east-west versus south-facing comparison uses PVGIS runs that we did ourselves, and we show the inputs.

Process posts cover what happens after you say yes, because the grid paperwork surprises some people. Read how long installation takes and G98 and G99 applications for the steps with your network operator. If your home is historic, check planning permission for solar panels first.

Protection posts help you avoid trouble. Our list of solar panel quote red flags shows the warning signs on a quote, and selling a house with solar panels covers the paperwork buyers ask for later.

How to use the blog with your quotes

First, read the post that matches your question. Then test your quote with the free solar quote checker, which works out the price per kWp in your browser. If you want to see more offers, you can request quotes through our form.

We are an independent comparison site and not an installer. Our posts also avoid guesses, so when we cannot source a figure, we leave it out. We update each post when the facts change, and the date at the top shows when we last checked it.
