The 12 panel PV array is located on 2 roofs facing South & West. For this project we used Siliken solar panels which came top in the recent Photon side-by-side tests of 30 solar panel brands.

Mr Jones says “Thanks for a really good job done yesterday and all your first class advice on the lead in to the installation. Just managed to get some time to take the following images from the roof of my shed. Haven’t seen so much sunshine for ages. We’re turning continental down here!”
