Solar collector

June 19, 2009

A solar collector is basically a device which is used to use the direct energy of the sun to store it in a more usable variety. Such a collector clubbed with a system of a heat transfer circuit and a proper storage system results in helpful commercial devices. Such systems can be used to fulfill various purposes, for domestic purposes these can be used for warming water or for warming swimming pools or for providing energy for a cooling system etc. Read the rest of this entry »


Photovoltaics deals with the conversion of solar energy directly to electricity, and is related to the technology and the research it involves. Because renewable sources of energy are much in demand now, solar photovoltaic energy is increasing in importance, and many options have been explored, in recent years. In fact, every two years, photovoltaic energy has been doubling, the increase is by almost 48-49% each year, since 2002, and thus, it is the world’s fastest growing energy technology.

Firstly, let’s understand what a solar cell is. Simply put, it is a device that converts sunlight into electricity, through the photovoltaic effect. Sometimes, lots of solar cells are assembled to make solar modules, solar panels, or even photovoltaic arrays. Those solar cells that can generate electricity with a higher efficiency than the usual or conventional solar cells are called high efficiency solar cells. These are more efficient because of their electrical output per incident energy, that is, watt/watt. Constant research is going on, to increase the efficiency of solar cells.
