Decided to add to existing roof array. Roof array gets quite a bit of shading from trees and especially in winter ends up with a very short solar day. It faces south east.
New array will be ground mounted vertically, more optimised for winter generation than summer. The vertical is also to protect from bits that can fall from overhanging trees.
So doing it on the cheap and myself, except the electric hookup.
Panels 12x 380W, 2 years previously installed life, bought for £700, plus a 3 hour drive each way to collect. Inverter (solic double mppt) again previously installed for about 12 months, bought for £150, collected on way from work. Isolators AC and DC, generation meter, stickers and MC4 connectors, £99.
Mounting frame being made from 4"x4" posts and unistrut. Which is mounted on the hill behind the house. Posts will be postcreted in.
Made a start on the frame. One half will be SW facing and the other half SSW facing.
