Solar Energy Systems – The Basics

Photovoltaic systems, also known as solar panels or passive solar energy systems, are slightly more complex than simple active or passive systems. They convert sun rays into electricity by the use of thin transparent sheets of solar cells. These solar cells are lightweight and inexpensive and can easily be added directly to roofing tiles. The added cost is offset by the lower energy costs throughout the year.


Photovoltaics Basics


PV systems are also used for producing electricity from thermal sources such as fossil fuels. There are two basic types of solar energy systems; active and passive. The passive system takes advantage of the natural phenomena of heat exchanges in a building or structure to harness the heat exchange power and convert it into electricity. In the passive solar thermal power stations, pipes containing water or steam are heated by means of convection, hence the name “performant” power stations. In the active solar energy systems, the source is a dynamo powered by an electric motor that is in constant motion.

These solar energy systems may use a variety of active components to accomplish their objectives. The PV panels and heat collectors are only one component of the overall system. It must be complemented by a qualified installer who can coordinate the connections of all components and ensure an even distribution of voltage throughout the building. The PV panels and heat collectors are connected in series or parallel depending on the distribution scheme required for the area.

Another major advantage of solar energy systems is the fact that they can generate electricity even in areas with a scarcity of natural sunlight. This is especially relevant in countries like India that have less sunlight than many other parts of the world. Some people argue that it would be better if the only sunlight a person’s house receives was direct sunlight. However, solar panels are designed to absorb the sun’s rays and change them into electricity. Thus, even in areas where there is no sunlight available a well-built and strategically placed array of solar panels can be used to generate electricity for domestic use.


Concentrating Solar-Thermal Power Basics


In a similar fashion, passive solar power can also be used to produce electricity even when there is no sunlight available. One way to accomplish this is to install a heating system that operates on the heat stored in water and oil. Water heaters and oil burners are examples of passive solar power systems that can be used to heat an entire home without consuming any electricity. There are also some home systems that use a combination of heat pumps and solar power to generate electricity.

Solar power has many advantages over conventional methods of generating electricity. One of the most obvious is the much lower initial cost of implementing solar energy systems. Another is the potential environmental savings when using solar power. Passive solar water heating and solar electric systems are cost-effective ways to warm up your home.
