How much do solar panels cost?

We'll help you to understand the cost of solar panel installation, so you can choose the payment option that's right for you.

Spread the cost of your solar panels

With our interest-free finance option you could get a typical 8 panel solar system installed at your home for just £120.11 per month1. This 8-panel system with on-roof solar panels starts from just £4,324, and a 12-panel system from just £5,191. 

Solar panels are a great way to generate your own electricity by using the sun's energy, and by adding battery storage could give you annual savings of up to £534 per year on your energy bills2 and reduce the carbon footprint of your home. Combining this with the Home Exclusive Energy tariff from E.ON could mean total savings of up to £874 per year3.

In fact, with our interest-free option, you could save as much as £25,860 over 25 years by having a solar system installed for your home4.

Prices can vary depending on the amount of panels you require, if your roof is in full sun or partial shade and what type of solar panels you want to have.

Pay in full

You can pay the full amount upfront for your solar system. There is no need for a credit check with this option so it's quick and easy to do. 

What does interest-free finance (0% APR) mean?

Paying for your solar panel system on finance lets you spread the costs by splitting it into manageable monthly payments. 0% APR means you'll pay no interest charges so all you're paying for is the solar panels and the cost of installation.
