Solar Power - Home Made Solar Panel 250watt - Failed - glass warped - not high temperature
I wanted to show the results of my efforts with building a home made solar cell. I encapsulated the cells on to the glass using Sylgar product, however the glass i ordered was supposed to be high temperature acrylic. Apparently not high temperature enough, as it was only a few days of exposure to the direct sun and the glass completely warped, breaking up many of the individual cells. Surprisingly the panel still seems to produce some useful wattage, but has become so hard to look at that i had to take it down as part of my primary solar array. :( Learn from my mistake. I started this project, and started ordering the pieces to build it, 2 years ago (i'm slow). In that short period of time the price of Photovoltaic solar panels has fallen dramatically. So much so that the panel i was looking at for $2400 is now only $540 (correction from video). WAY WAY easier to buy proper manufactured panel. Building one from scratch is A LOT of work and soldering. So much soldering that the fumes become an issue and should be done in very well ventilated area or outside. In this video i'm just playing with a self oscillating circuit i built and listening to the fluctuation in the current flow.
