Generally once the scaffolding has been errected the installation would usually be completed in 1-2 days.

Yes, 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 the intensity of light not necessarily direct sunlight, so even when its overcast, your solar panels will be producing clean electricity to help power your property.

Not essential no, the system is connected to the national grid. In the night, when the cells are not generating energy, electricity is bought from the utility company in the normal way. Any excess electricity generated during the day, for example when you are at work, is sold back to the grid. However if you were to have a battery storage system added you are able to retain and store the spare electricity generated which can be utilised once the sun goes down to further reduce your electricty bills.

Photovoltaic systems for properties are entirely grid connected. If there is a power cut your system is automatically switched off. This is a safety measure designed to stop electricity leaking onto the national grid and protect individuals who may be working to restore the power supply.

Solar PV systems are silent in operation, having no moving parts and require no maintenance. Most of the time rain will keep the modules clean. However a build up of dirt can affect system performance. The modules can be cleaned with either a hose or if possible, soapy water and a non-abrasive brush.

A photovoltaic system that is designed, installed and maintained well will operate for more than 20 years. The PV module, with no moving parts, has an expected lifetime exceeding 30 years.
