The Potential of Photovoltaic Energy

Each day that we walk the earth the sun is occupied with the task of delivering free energy to the earth and its inhabitants. Many people are realizing that this free energy or the technology of photovoltaic is able to generate electricity from the sun’s energy. The power of photovoltaic is phenomenal as this form of technology has the ability to harness and store an unlimited amount, from the Sun, of electrical energy.

The most awe-inspiring statistic is that there is enough solar radiation available in locations around the globe that can meet the need of the consumers increased demands for energy. Experts have proposed that the sun creates an amount of energy reaching the surface of the earth that can provide enough electricity to take care of the needs of annual energy consumption worldwide ten thousand times over.

To create the amount of energy needed to supply the globe’s energy needs the electricity generated by a photovoltaic system would use a modest electricity output per square meter of 100kWh. This means that the solar area that would be required in order to capture the energy would take up 150 x 150 km. The largest part of the photovoltaic capture area would have to be located on the walls or roofs of buildings. This is an advantage of photovoltaic energy because a capture area would not use extra land.
