Our customer reviews

I had a Solar and battery system installed by Wil-lec and couldn't be happier. The fitters where nice and polite, the quality of the work was superb. Very straightforward project from start to finish.
- Dave Ellis
Originally I had a 5.2 batt with the system and 13 panels fitted last Aug. It was agreed at the time that I may need extra batt power depending on usage but see how it went. Well this good sunshine had convinced me to order another batt and use the juice instead of sending the extra to the grid. One e-mail and 2 weeks later it was fitted. Really happy with their top quality service and top quality professional fitters. Thank you !
- Andy Smith
Wil-Lecs guys made a great job of installing an inverter and batteries to the pv panels that they installed a few years ago. They set up the system and showed us how it worked and made sure the phone app was working too. Nothing was too much trouble and everthing was left neat and tidy.
