Solar power is the technology of harnessing and producing usable energy from the sun's light. It is already used in a number of ways such as heating, electricity generation, and desalination of seawater. Solar electric power, converting sunlight into electricity, is called photovoltaic (PV) power generation.
Clean Quiet Renewable Self sufficient Non-polluting Lightweight No running costs Scalable
Photovoltaic devices, generally called solar cells, consist of two or more thin layers of semi-conducting material, usually silicon.
The layers are given opposite charges; one positive, one negative. When sunlight strikes the solar cell, electrons are knocked loose and move toward the treated front surface of the solar cell. This creates an electron imbalance between the front and back of the cell and creates a direct current (DC) which is converted to AC current and then fed back into the house's electrical network.
PV cells are typically encapsulated between sheets of glass in a solar panel. The panels are then connected together to form a solar array.
The amount of energy generated by the solar array will vary according to the level of sunlight and time of year. In the summer months the system will typically generate five times the power generated during winter.
Historically the use of solar cells has been limited due to expensive manufacturing costs and relatively low solar cell efficiency. More recently, advances in research and scale of production have both reduced costs and increased efficiences.
By installing aSolar PV system, you will become your own power generator.
Solar PV systems cause very little disruption because they are substantively installed outside the house or on your roof. Due to recent changes in planning regulations, they are even easier to install than ever before. We can install solar systems either on your roof or stand-alone on a ground mounted structure.
PV systems are grid-connected so do not require any battery. The solar array generates DC current by day which is converted to AC current and then fed back into the house’s electrical network. Presuming that there are some appliances in the house in operation, the electricity generated is used effectively to power these directly. Any surplus is exported back into the grid through an export meter, for which you receive payment or credit according to the tariff you have chosen. You hence become a buyer and seller of electricity, exporting power available by day through your solar system, and importing by night from the grid.
