Solar 12V charging voltage regulator circuit
We all know pretty well about solar panels and their functions. The basic functions of these amazing devices is to convert solar energy or sun light into electricity. Basically a solar panel is made up with discrete sections of individual photo voltaic cells. Each of these cells are able to generate a tiny magnitude of electrical power,. The voltage acquired from a solar panelis never stable and varies drastically according to the position of the sun and intensity of the sun rays and of course on the degree of incidence over the solar panel. This voltage if fed to the battery for charging can cause harm. The charging current may be selected by appropriately selecting the value of the resistors R3. It can be done by solving the formula: 0.6/R3 = 1/10 battery AH The preset VR1 is adjusted for getting the required charging voltage from the regulator.
