How to Generate Solar Energy

The ultimate resource of the planet Earth today is the sun, which provides the planet with heat, radiation and light. There are a lot of technologies that source energy from fossil fuels to generate electricity. The undeniable fact is that the sun showers the Earth in a stable and steady form of energy that surpasses what the planet needs for electricity consumption.  Modern-day technology has developed rapidly and knows how to generate solar energy very efficiently and yet simply –  it fundamentally converts the sun’s power into electricity.

In view of the fact that producing electricity directly from the sunlight does not drain any of the planet’s natural resources, and is supplying the planet with energy continuously, solar energy is a source that can be renewed anytime and used to generate electricity. To put things bluntly, the planet Earth’s principal source of renewable energy is solar energy.

PV or photovoltaic is one of two basic types of approaches in turning the sun’s power into electricity.  Originally formulated for a space program more than 30 years ago, a photovoltaic device (commonly labeled a fuel cell), relies on the build-up of chemical responses to produce electricity. PV cells are tiny, square, semiconductors covered in slim film layers from conductive materials and silicon. When sunlight hits a photovoltaic cell, it causes some chemical reactions and release electrons, producing electric current. These photovoltaic cells are then installed in modules and can power a home as well as a business or can be plugged into an electricity grid. In today’s economic climate, you find more and more people fitting these to the roof of their house in order to drive down their energy bill.

The second basic type of approach is the solar-thermal technology. This approach is a relatively conventional type of electricity generating process. It uses the sun’s temperature to heat water and produce steam to drive electric generators. A solar thermal collector is a device purposely intended to accumulate heat: To be exact, absorbing sunlight to produce heat. While the expression may be applicable to an uncomplicated solar hot water panel, it is frequently used to denote extra intricate installations. There are an assortment of forms of thermal collectors, for instance, solar trough, solar towers, and solar parabolic. These kinds of collectors are commonly used in a solar power plant where solar temperature is utilized to produce electricity by heating up water to create steam which drives a turbine linked to an electrical generator.

Two further types of solar-thermal technologies are nearing to be categorized as marketable. One is the parabolic dish system.  It is the most dominant type of collector which focuses sunlight in a single, central point, through one or more parabolic dishes — set in a comparable method to a reflecting telescope focusing starlight, or a dish antenna focusing radio waves.

The second type of solar-thermal technology is the central receiver system. Conceptualized for solar energy absorption and gathering is based on a field of independently sun-tracking mirrors that echoes the occurrence of sunshine to a recipient at the top of a tower located midpoint.  On average, 80 to 95 percent of the replicated energy is engaged into the working fluid which will be then pumped up the tower and into the recipient.  The heated liquid forms a stream down the tower and then into a thermal converter more likely to a thermal electrical power plant.

The fundamental disparity between the central receiver system and the parabolic dish system, is all of the solar energy to be accumulated in the whole field, is passed on optically to a miniature central collection station rather than being channeled around a field as hot liquid.  Due to this characteristic, all central receiver systems are distinguished by high temperatures and large power levels.

Energy and power is derived in due course from the sun. It may be direct or indirect, but the fact of the matter is energy sources on Earth are types of indirect solar energy. Although we usually don’t consider them that way, oil, coal and natural gasses derived from prehistoric biological material which obtained its energy from the sun (photosynthesis) thousands of years ago. Knowing how to generate solar energy economically is definitely a must-know for the next generation and to put a stop to depleting the earths natural resources.
