One of the largest forms of renewable energy available is solar. In order to convert the radiation from the sun to electric power, photovoltaic cells are required. The photovoltaic effect is the process by which the radiation is converted. Read on about photovoltaics and the advancement of solar energy.

Solar technologies are generally characterized by the way in which the solar radiation is captured. There is passive solar, which refers to the conversion of sunlight to useful energy without the assistance of any type mechanical devices (solarium). Active solar refers to the conversion of sunlight by means of some type electrical or mechanical equipment. Photovoltaic cells can be used in both passive and active solar capture.

The photovoltaic effect is best described as a material being subjected to electromagnetic radiation. Voltage is created with the charged material. Alexandre-Edmond Becquerel was the first to notice this effect in 1839.

The amount of solar energy that comes to the surface of the earth is so great that in one year it will exceeds double the amount of all the non-renewable resources of oil, coal, mined uranium, and natural gas combined on the earth. Different levels of solar energy can be captured in different areas around the world. The closer a location is to the equator, the more solar energy available.

Spacecraft and orbiting satellites were the first to use the photovoltaic cell. The cells are now used for many things including power. A cell module or a solar cell can produce a direct current, and to be used for residential and commercial use, it then needs to be converted to alternating current.

Solar panels that are made up of photovoltaic cells at one time were entirely too expensive to use at home or for general commercial use. Government incentive programs have made it possible for consumers to install systems at this time. Individuals are being encouraged worldwide to switch to renewable energy sources. Fortunately, over the past several years, the cost of solar panels have also decreased on their own.

When photovoltaic cells were first introduced to the public, they had menial uses, such as calculators and gadgets, but now, we are testing roadway lighting systems. The presence of them can be seen in street lamps, parking meters, and phones. There are power stations in different areas of the world in operation with photovoltaic panels. There is no doubt that the need for them will grow with the need for renewable energy.
