One of most abundant sources of energy on this planet today is the energy of the sun. The solar energy if harnessed properly can be utilized to generate power on a very large scale as the surface of the earth receives a large quantity of sunlight daily. And today with the use of solar photovoltaic or solar PV systems, this energy of the sun can be effectively used to generate electricity.

What is Solar PV?

Probably the most basic question that comes to every individual's mind when talking about the solar photovoltaic technology is the what factor. The solar photovoltaic is a technology which is used to collect the solar energy and thereby convert it into electricity. This technology uses the photovoltaic cells which work on the basic principle of producing electrons, responsible for electricity generation, when sunlight falls on them.

The Concept of Working

The solar PV technology works on the fundamental notion of using a semi-conducting material, which is silicon, in the photovoltaic cells. These cells are capable of collecting the sunlight and converting it into electricity through the excitement ...
... of electrons. Of course the electricity that is produced is in the form of direct current (DC) which is then converted into alternating current (AC) with the help of an inverter.

Pros and Cons

Now the solar energy can be harnessed and utilized to generate power through the use of two technologies, the solar thermal energy (STE) and the solar photovoltaic technology. The STE basically converts the solar energy into heat energy which is useful for heating and cooking purposes. The solar PV technology on the other hand is used to convert the solar energy into electricity and has the following pros and cons.

Pros:
It produces clean and pollution free electricity.
As the solar energy is inexhaustible, this has no risks of depletion.
The energy so harnessed can be elementary in fulfilling the household needs.

Cons:
The initial setup price and the cost of raw materials is high.
The average efficiency for this technology is not more than 20%
There maybe problems if there is no sunlight in cloudy conditions.

Therefore it can be rightly said, when thinking about the future and the gradual depletion of the present exhaustible sources of energy, the solar PV technology is the best solution in hand.
