A TRACKING SOLAR CONCENTRATOR
- Caution: This panel and the motors use voltages that are hazardous or lethal, 120 VAC. Make sure that your wiring conforms with local codes.
- Do not attempt the line voltage (120 volt) wiring unless you are qualified to do it safely and legally.
The electronic circuitry is most easily assembled on a printed circuit board. figure 42. The pc board is 3" x 6", page 69 will link to a higher resolution, 300 pixels/inch, suitable for many printers. The parts placement guide is The parts placement guide is in figure 43. The circuit can of course be assembled on "perf" board, as the prototype originally was, but there is a much higher risk of error in this approach. Be sure to observe polarities and pin basing when you mount parts other than the resistors. For gosh sakes, use high grade 63/37 electronic quality solder. Mount the board on your control panel spaced sufficiently high to prevent interferance with other components and wire the 4 lines to the relays according to figure 38. Connect the sensor inputs to TB2 according to figure 38. Connect the power supply and regulator according figure 38 also.
