Solar panels, or photovoltaic cells (PV), are normally attached to the roof or walls of any building that needs providing with electricity.
The PV cells are constructed with either one of two layers of semiconducting material using silicon. When the sunlight shines on the device it creates an electrical field. The stronger the sun’s rays, the more energy that will be produced.
Solar panels come in a variety of shapes and sizes including the standard ‘grey’ cells that are seen on house rooftops. It’s also possible to have transparent cells installed onto greenhouses.
The strength of the solar panel is measured in kilowatt peak (KWp). This would be the amount of electricity generated in full sunshine.
Solar panels are extremely reliable as there are no moving parts so you don’t have to worry about replacing anything. In fact, most people generate electricity for 1,000s of hours with little or no maintenance.
Solar cells make no noise while collecting energy. There are no other renewable energy sources that are completely silent.
In the long run, solar electricity is cheaper than buying it from the power companies. There is a start up cost, but then it starts paying for itself.
There are a huge variety of solar panel systems available. This means anyone can get into solar, there’s an entry point for just about everybody.
You’re not required to connect to the power grid. You can be completely self-sufficient and live off-the-grid if you want to. Imagine never paying another monthly bill.
Sell your excess electricity. You earn a fixed income for every kilowatt of electricity you generate and use in your property plus an additional amount when you export any surplus back to the grid.
Most governments provide some kind of energy saving grants for people purchasing solar energy systems.
Solar technology is constantly improving. Solar installations are increasing every year, most of which are small home systems.
