Instructions
You often see signs around construction sites that are solar powered, from time to time these signs will get damaged from drunk drivers or rubber-neckers passing through construction areas. Look closely at the signs and you will find a sticker with the phone number of the traffic sign rental contractor. Use your pen and paper to write down this number.
Ask for the shop maintaince manager or head mechanic and ask him for free damaged panels.If you have kids who enjoy doing experments, have them ask. Most companies love to help kids doing a school or class project. Most all traffic rental sign contractors have free solar panels that have some cracks or slightly damaged when drunk drivers hit the parked sign trailers. They replace them and throw away the damaged ones. We started asking for them and they let us have them for free. most of the panels work but only put off 50% to 75% power off, but for free who would complain when they cost 2200.00 each new.
Test and repair the damaged panels as needed, cracks can be resealed with clear silicone. Wiring can be soldered back together. Thank the shop mechanic with a box of doughnuts and he might even call you when he has some more discard solar panels!
