Here is the schematic diagram of my regulator. You may want to print it out, and then go on reading. This regulator is designed for 12V systems employing panels of up to 7A total current, and loads of not over 20A. It can be easily modified for greater currents.

Solar panel regulators come in many flavors. The plainest flavor is the simple on-off type shunt regulator. It has the advantage of simplicity, extremely small power dissipation, low cost, high reliability, but in exchange for these advantages one has to accept that the voltage on the battery is always going slightly up and down, that [...]

For regulating a solar panel’s output, there are several possible ways. A linear series regulator can be used, but has the disadvantage of causing some voltage drop and having some internal power consumption at times when the sun is weak and the load is heavy. It’s much better to use a shunt regulator, which is [...]
