As we know electricity has become essential commodity to drive this world forward. The growing demand for energy is increasing as the population is rising every year by year. Without energy it is very difficult for industrial development of any country. Presently our energy production is mainly from coal, hydro and gas. Now a day these energy producers are becoming rare on the earth and the situation is warning for searching alternative energy resources. Scientists have found a way towards non-conventional energy sources like bio-gas, wind and solar energy. This article is mainly deals with solar energy.

The biggest achievement for mankind is conversion of sun light into useful energy form i.e., electricity. Sun light is abundant on earth and can be used as raw material for the production of electricity. Also you need not spend any dime for buying this raw material. More over unlike conventional energy sources, this solar energy will be long lasting in future for many years and your chief raw material is continuously available for without any additional cost. Now it is wise decision to utilize this free sun light energy to meet our daily energy requirements without depending on state electricity boards. But how can we achieve this and reduce the Nation’s worry for power demand. Yes, it is quite simple, you can produce electricity at your own place and glow your house using energy produced by you. You can build solar panels at home and conveniently utilize the power to your regular needs.

Solar panels are consisting of solar cells. The function of solar cells is simple. These are the photo voltaic cells that generate electricity when light energy is absorbed from a light source. The principle of photo electric effect is responsible for the generation of electricity. These entire cells are joined for charge transfer from one end to another. Depends up on the load requirement, you can install these solar panels for an individual house or for many houses in an apartment complex.

There are many advantages using solar panels. It is free and non-polluting and gives environmentally clean energy. It reduces dependency on oil, water and coal as these reserves are fast depleting. The basic raw material required for production of electricity using solar panels is abundantly available. Finally solar panel operation and maintenance costs are very less.

The only major disadvantage is that it is completely dependent on sun energy and if whether becomes cloudy, rainy and dim light conditions, it becomes very less intensive in the production of electricity. Of late lot of research has been done to off-set the dis-advantages of solar power for use in nights and monsoon conditions is to use dry-cell batteries, storing in the form of heat etc. You also can lit-up your house entirely by solar power by using build solar panels at home.
