Solar panels or photovoltaic panels are devices that convert light from the sun directly into electrical energy. Solar panels comprises of several solar cells that are interconnected with both series and shunt (parallel) configuration. The sun can provides enough energy for all human needs if only it could be well harnessed. Solar power is one of the alternative energy sources that has seen a lot of development in the past two decades.
The principle of operation of solar cells can be explained using Einstein's photoelectric effect theory. But first, it is good to know the physical structure. A solar cell is a semiconductor device that is made up of two or more differently doped layers that form junctions. These junctions respond to various wavelengths of light. Sunlight, or any other light is made up of tiny packets of energy know as photons. The sun produces about 1000 watts per square meter.
When a photon hits the surface of a solar cell, electrons are stripped off and becomes free. This effect causes an electric field to form at the junction which attracts electrons from one junction (n-type side) to the other (p-type side) through an external circuit. The flow of these electrons from the n-type side to the p-type side creates an electric current.
The voltage generated by each solar cell is usually very small and cannot have a practical use. To overcome this, several solar cells are connected together to produce a useful amount of energy. One solar cell can generate a current of about 0.2A at 1.2V giving an output power of 0.24W. A connection of solar cells forms a solar panel. The panels can further be connected to form modules.
In the UK, the new Green Deal is the key to figuring out which improvements will help homes and businesses be more productive. It is also the key to getting qualified for access to solar panel grants and loans in the United Kingdom. To understand this, learn a bit more how the UK Green Deal works.
This government program works with private businesses and property owners in order to encourage improvements that help save energy and produce energy more efficiently and in a cleaner way. Once a home is analyzed for its present condition and possible improvement, this program also helps both home and business owners find ways to finance them.
These are some typical improvements that might be suggested as ways to help save power, money, and the climate:
Generation of renewable energy, including solar panel installations, wind power, and heat pumps
The UK Green Deal website provides a lot of information about this program.
You might be interested in qualifying for grants or other kinds of financial assistance with energy bills. The government website even has a grant calculator that you can use to get an estimate of any help you might hope to qualify for. All you need to start is a general idea of the age of your building and any improvements that you have already installed.
