Making a low cost solar panel
Here’s something I found via Slashdot.
Chris van der Zwaal from OliNo Renewable Energy has been making low cost solar panels from smaller cells he picked up cheap on ebay.
I’ve been thinking of using solar power myself to run a ventilation fan for the workshop, the idea being that the hotter it gets the more power is availble for the fan. Hopefully some fresh air running through the place will keep the humidity levels under better control too.
