Got it figured out ? Solar Ventilation

GreenPowerManiac

Was experimenting with my homemade Solar panels & ventilation. Before, they'd fog up a bit with air moisture. The unfortunate disadvantage of using wood frames, they can't be vacuum sealed. However, I experimented with one panel that was fogging up and drilled 10 - 1/4" holes in the bottom and top of panel (the wood 1" spacer between the plywood and plexiglass) . Screened them off for bugs and put a piece of form fitted "J" channel (screwed down) and used it as ridge vent to keep water out. I must say the fogging thing is in the past. We've had a few rainy days and a couple days of heavy frost and it didn't faze it one bit. The past few weeks have proven worthy of my efforts. The cells produce heat and it's quickly dissipated.

I will have to do the same thing. My homemade panels get condensation in them overnight and stays in most of the day. Its my first panel, I will ventilate the next one, this week I hope.

Make sure the panels are on at least a 45 degree angle so any condensation drains on the inside of the glass towards a drilled hole and not onto a cell.
