in this video we are building a solar tracker using an 2 by 1.5 ft solar panel. I tested the maximum input from the solar panel at the optimal angle at the hottest part of the day. I get a 18v at no load and 12v with 1.2 amps with a 12v load. so the panel is about 15-20 watts. I built this solar tracker to track the sun to the get the most efficiency from it. I made most of the part out of aluminium because it would be outside.
Material:
varies aluminium extrudes
4 inch lazy susan
dc motor( geared)
gears
solar panels
arudino
12v battery
