What is the return on investment for solar panels in Harwell?

Most homeowners in Harwell recoup their solar investment within 6 to 8 years through reduced electricity bills and Smart Export Guarantee payments.

Do I need planning permission for solar panels in Harwell?

In Harwell (OX11), most domestic solar panel installations fall under permitted development rights, meaning no planning application is needed.

Your installer will advise during the site survey.

"We had a 6kW solar PV system installed on our south-facing roof last spring. The whole process from survey to switch-on took just three days. Our electricity bills have dropped by nearly two-thirds, and we are now earning from the Smart Export Guarantee on top. Best home improvement we have ever made — wish we had done it years ago."
