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 discrete sections of individual photo voltaic cells. Each of these cells are able to generate a tiny magnitude of electrical power, normally around

1. 5 to 3 volts. Many of these cells over the panel are wired in series so that the total effective voltage generated by the entire unit mounts up to an usable 12 volts or 24 volts outputs. The power generated from a solar panel is normally used for charging a lead acid battery. The lead acid battery when fully charged is used with an inverter for acquiring the required AC mains voltage for powering the house electrical. Ideally the sun rays should be incident over the surface of the panel for it to function optimally. However since the sun is never still, the panel needs to track or follow the suns path constantly so that it generates electricity at an efficient rate. If you are interested to build an automatic dual tracker solar panel system you may refer one of my earlier articles. Without a solar tracker, the solar panel will be able to do the conversions only at around 30 % efficiency. Coming back to our actual discussions about solar panels, this device may be considered the heart of the system as far converting solar energy into electricity is concerned, however the electricity generated requires a lot of dimensioning to be done before it can be used effectively in the preceding grid tie system. The voltage acquired from a solar panel is 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...
