What are the benefits of solar energy? Solar photovoltaic (PV) panels allow you to generate your own electricity using energy from the sun. Consequently by generating your own electricity you could save on your energy bills. Additionally you could be eligible for further income from FITs.

How do solar panels work? Solar panels convert daylight into electricity. First light shining on the panel creates an electric field across layers of silicon in each cell, causing DC electricity to flow. Second an ‘inverter’ converts this into the usable AC electricity that powers our homes. Surprisingly some people don’t realise solar panels do not need direct sunshine in order to work, just daylight, so they can still generate electricity on cloudy days.

Is there enough sun in the UK for solar panels to work effectively? Yes. In general solar panels have a high efficiency and for this reason they perform very well in the UK, which has similar daylight levels to Germany. Solar panels utilise daylight instead of direct sunlight, which many people overlook .

Do I need planning permission for solar panels? The installation of solar panels on non domestic buildings and land may be ‘permitted development’. In that case there is no need to apply for planning permission. There are, however, important limits and conditions which must be met to benefit from these permitted development rights.

Does the solar PV system need servicing? You do not normally need to service a solar PV system as it has no moving parts and other components, such as cables and connectors, are designed to withstand environmental conditions. We suggest you routinely visually inspect your system though (from ground level only) and if you notice any damage, we’re here to advise you.
