New ground mount PV array

[sgt_woulds]

I'd still question the overhangs of the top l/h/ sides, especialy when using a washer rather than an engineered clamp.

 

You are probably not concerned with warranties, and the trees behind do offer a wind break, but manufacturers specify clamp zones for a reason, and the joy of unistrut is that it is easy to customize as required.

 

It's hard to tell from the pictures, but it looks like some of those washers may be partially covering cells which can lead to localised cell burn out and reduced output.

I'll nip into town later and pickup some proper centre clamps. Will struggle to correct the LH side clamping zone. Some of the clamping zone will take some thinking about. 

 

Prevailing wind is directly on the front of the panels. Any wind from behind sails straight over the panels due to the hill.
