Why Is My Solar System Not Working?
If your solar panels aren't generating power, the inverter is the most common cause. A faulty inverter means you're losing out on:
- Savings: Every sunny day is a lost opportunity to reduce your energy bills.
- Feed-in Tariff (FIT) / Export Income: No generation means no payments.
- System Value: Your initial investment isn't delivering its full potential.

Our customer reviews
I’m happy that I used Wil-Lec to perform my solar installation and felt that good care was taken not to disrupt my home, giving me peace of mind from a great investment. Wil-Lec went above and beyond in helping me with any questions that I had before, during, and after the installation took place.

I am very pleased that I had my solar system installed by Wil-Lec. The whole process was explained to me clearly and accurately and I was impressed by the level of professionalism shown by the team that fitted the system. I would recommend the staff at Wil-Lec to anyone wanting to have solar installed.
- J Thompson, Grimsby
Following my initial enquiry into having solar installed, I believe that I made the right choice in using Wil-Lec. Works were completed quickly and I am impressed by how much money I have received back since it has been installed. Even after I paid, Steve was happy to answer any queries that I had.
