There are various types of solar panel and component parts available. To qualify for Feed in Tariffs, all of the component parts must carry a MCS accreditation. At AES we ensure all of the components that we use carry the MCS accreditation, making us one of the leading solar panel array suppliers in Worcester, Cheltenham, Kidderminster, Hereford and surrounding areas.
PV Solar (Photovoltaic)
PV Solar panels are commonly used in the UK to provide renewable energy to homes and businesses across the country. PV Solar (Photovoltaic), uses the sun's energy to provide a clean and sustainable power source for electricity.
How it works
A photovoltaic solar panel is made from either monocrystalline or polycrystalline silicon cells. These cells react to daylight and generate an electrical current. These cells are connected together to form a panel. The solar panels vary in their power output. Power outputs vary depending manufacturer and model type. 'Standard' panels are normally 185kWp (kilowatt peak), there are also higher performance panels reaching 250kWp and above.
Monocrystalline panels are more efficient than polycrystalline panels, however for installations in the UK the difference in the power output is negligible, so either are acceptable. Panels work during daylight from an east to west orientation and from a flat to vertical angle, though they are most efficient facing south and at an angle of 30 to 40 degrees.
There is also Amorphous silicone panels. This type of array is flexible, light-weight and less reliant on angle and orientation. They are less efficient than the rigid mono or poly panels so require a greater surface area to achieve the equivalent output, but the array is around 1/3 of the weight of the standard rigid panels and per kWp installed the price is usually comparable. The Amorphous solar arrays are ideally suited to flat roofs or larger roof areas where standard arrays would be too heavy for the structures in place.
With the solar panels producing Direct Current (DC), an inverter is required to convert this to Alternating Current (AC) so the electricity can be synchronised and used with the mains power in the building. Inverters are usually sited close to the array to minimise the amount of voltage loss, which can be experienced from DC power, through long cable runs. From the inverter a generation meter is installed to measure the amount of electricity produced. This meter is where the Feed-in Tariff payments are calculated. From the generation meter is electricity is then fed into the property and is free to use with any surplus electricity automatically being fed back into the national grid.
