Solar power is converted energy from the sun that generates electricity. The electricity generated can be exported into the electricity grid and/or supplement electricity for running home appliances and business operations. The process of conversion requires a solar power system, the main component of which, are photovoltaic cells that make up solar panels. The idea behind the development of equipment to 'harvest solar energy' and transform it into a usable energy was harnessed by American scientists in the 1950s, when they were looking for ways to fuel space satellites. Today, much of solar powersystems have been developed so that they can be easily installed wherever the sun shows its face and in turn, benefit the owner and the entire planet.
What are Photovoltaic Cells?
Photovoltaic (PV) cells are the core of solar energy conversion technology. They are made up of positive and negative slice of silicone under a thin piece of glass. These solar panelsor PV tiles convert sunlight into clean energy that can be used at home and in the workplace in lieu of conventional energy sources, which are generated from non-renewable fossil fuels. Once sunlight strikes the surface of the PV panels, the silicone does its work in trapping negatively charged neutrons under a magnetic field.
The neutrons are then relayed via wires to form an electric current. The reaction results in D/C electricity, which is then converted into alternating current or A/C after passing through an inverter. By then, the energy is ready to be exported into the electricity grid and/or for running appliances, lighting, and office equipment.
Solar Power Applications
Some common applications of solar electricity apart from operating appliances include heating pools or water for showers and baths. It may also be used to fuel your home's central heating system. The grid-interactive solar system, when mounted on the roof of your house, can export electricity to the grid and/or partially supplement your home's energy requirements. Solar energy may also be used to light your garden, fountains, or house number plates. With manufacturers continuously improving Solar Panels, the list of possibilities continue to get longer.
Apart from offering a means of reducing your electricity bills, homes and businesses may also enjoy the benefits of the subsidies available from solar rebates and renewable energy certificates(REC). The rebates and/or renewable energy certificates reduce the cost of ownership to the customer and assist the nation in achieving its mandatory renewable energy targets.
Costs of Solar Power Systems
The amount you need to spend to fund a functional solar power system in your home or workplace would depend on several factors including your energy requirements, your location, and the type of system you have installed. The cost of ownership can vary depending on the quality and size of system you chose and the state and zone in which you live. Different states and zones have different feed in tariffsand renewable energy certificate entitlements respectively. Systems can start from as little as $4,000.
