Real stories from satisfied customers

The Solfit system is really impressive - a great design and very well thought out. I’m not sure how you could make it much better! The installation process was straightforward, and the YouTube video guide was particularly clear and easy to follow. Overall though, it’s a brilliant system that’s easy to install and delivers a high-quality finish.

Ordering the kits via EasyPV seemed straight forward had no problems with the order.
Having fitted numerous in-roof systems over the years, the Solfit system has quickly become our go-to choice. It’s incredibly easy and fast to install, and the finished result looks fantastic. We’ve now installed a few systems and confidently recommend Solfit to all our customers.

OVO Solar and Heating South Wales

We found the Solfit system very straightforward to install after completing the online tutorial. Previous experience with other integrated systems has provided countless headaches with less durable materials expected to replace a traditional rail system. Our personal highlight was securing the panels with a direct fixing as opposed to traditional clamps, which enhanced efficiency by allowing the panels to be fitted earlier on in the project, freeing up time for finer details like trims and finishes.

The final product is visually satisfying, and our customer was very impressed with the overall quality and performance.

It’s great to see the Solfit system under the spotlight on our Belper sites. The integration into the roof looks fantastic, and we’ve now fitted over 1,000 panels. It’s a really impressive system — well designed, easy to install, and a great fit for our specification as we move towards the new Future Homes Standard.
