In this topic I would like to briefly tell you all about solarpowersystems.org. Everybody knows that the Sun is the most important source of energy on Earth. It is necessary for all living organisms existing on our planet. Sunlight reaches every part of our planet and the amount of sunlight greatly depends on the location or season. Solar companies have learnt how to use photovoltaic (PV) processes, catching the energy and turning it into more practical forms. Every cell of solar panels contains semiconductor substances. Sunlight hits these cells knocking the electrons off the atoms. While drifting around the cells, the electrons produce electricity. This process creates a direct current; after that they are captured by solar panels and converted into alternating current. It is the type of current that we use for home appliances. The best benefits of solar power is that it is a cheap and clean source of electricity, and using this green energy we care about our planet.
