I will donate plans for building this 1000 watt tracker to an educational institution. It could easily be 1240 watts (4 x 310 watt panels)
The plans will include mechanical design and fabrication steps, electrical schematics and the Arduino code for an Arduino UNO. E-mail me with contact information to the school. It is a good project for vocational programs, teaching Arduino programming and good practices for wiring control panels. It also requires machining, and welding.
