Solar collector main theme is collect radiation from sun and it transfer to heat energy or electricity to other storage such as a battery. One can use various types of solar collector such as a disk, flat and tube in thermally. In solar collector radiation absorb but the amount of supply heat is greater than absorb of heat. Radiation is mainly depends on environment, place, temperature, sunlight and air. For running a turbine solar collector used for initially running. If a collector any one compare concentrating solar and non concentrating solar collector there have basic difference such as concentrating solar has more benefits because it received radiation in whole area. In 1950 two person whore they Hottel & Whillier give a new theme to us for flat plate solar collector which has more benefit. A flat plate solar collector has some gradient such as it contain fluid for received heat from dark plate where fluid used as a water, air and so on, In this flat plate dark place must be insulated for do not heat come and go in this system from outside. As a absorber there use a metals such as aluminum and copper which is more prefer for it’s low cost and high corrosion resistance and getting high efficiency with a good service and performance. Application of flat solar collector is mainly used for electricity for reducing high cost of bill in a house building or industry. In commercially it also manufactured for cars, energy storage, laundry and so on. There are some basic difference among tube and flat solar collector such as tube collector has space where stored water fluid or air fluid which is contain or set up in middle position of two collector. For these it absorb radiation is not a continuous process but flat plate solar collector is a continuous process.
