The easiest and fastest way to do that is via your account. If you log in to your account you can view your orders. Next to the items that can still be returned, you will see a return button. If you click on this, you’ll go through the return process. You will then receive the address details and further instructions for free return of your order as soon as possible.
If you do not have an account, please contact our customer service via +44 (0)20 3695 5900 or send an e-mail to customer-service@solarpowersupply.eu
