My second batch of 'broken' solar cells turned up today, so I now have 50 pv cells waiting to be made into a panel. My main concern, is the damp and wet British weather.
When its raining, I want to keep the water out.
When its damp I want to stop condensation forming
When its hot, I want to keep the cells cooled.
I'm thinking that I will build a ventilated panel, if all goes as planned this will stop condensation and help keep the cells cool on the hot sunny days.
The solar cells are fragile (very fragile) and I'm concerned that high humidity over the Autumn, Winter and Spring will damage both the cells and the soldered joints.
I would really like to encapsulate, or paint the cells with some sort of waterproof and UV resistant coating - some sort of acrylic laquer, or maybe a two part resin?
Anyone got any ideas on what could be used? Also is it safe to paint directly onto the surface of a pv cell?
