We have tried to answer the most common questions you are likely to have.
We expect that you have many more questions about the solar pv system you are considering so please don’t hesitate to contact us and speak to one of our friendly staff.
- PV modules (groups of PV cells), which are commonly called PV panels
- an inverter for converting alternating current (ac) rather than direct current (dc) is required
- wiring and isolator switches and
- mounting hardware or a framework
All current cells rely on doped silicone, but they are manufactured in a variety of ways to give monocrystalline, polycrystalline or hybrid (thin film over monocrystalline) panels. The first two varieties offer the best value for money, but hybrid offers the greatest energy generating density.
All Solar PV cells rely on light from the sun, not on heat. PV cells can therefore work in the winter and on overcast days and are limited primarily by the hours of daylight and the angle of the sun in the sky.

Solar panel suppliers have enhanced the efficiency of solar power systems to the extent that it is now a very viable option even in cloudier climates.
The important thing to bear in mind is that solar power depends on intensity of light, not necessarily direct sunlight. So even when it’s overcast, your solar panels will be producing clean electricity to help power your home.
Under this scheme energy suppliers have to (compulsory for big six suppliers) make regular payments to householders and communities who generate their own electricity from renewable or low carbon sources such as solar electricity panels(PV) or wind turbines.

- Photovoltaic (PV) systems, which convert sunlight directly to electricity by means of PV cells made of semiconductor materials.
- Concentrating solar power (CSP) systems, which concentrate the sun’s energy using reflective devices such as troughs or mirror panels to produce heat that is then used to generate electricity.
- Solar water heating systems, which contain a solar collector that faces the sun and either heats water directly or heats a working fluid that, in turn, is used to heat water.
- Transpired solar collectors, or solar walls, which use solar energy to preheat ventilation air for a building.
