Why Solar PV

Why Solar PV

 

Great investment

Solar PV can be a great investment, especially in combination with a heat pump. As more and more home owners buy electric cars, generating your own electricity can be a great cost saving method.

Good for the planet

Solar PV panels generate electricity without emitting CO2. A typical 4 kW solar PV installation generates around 3,300 kWh per year; corresponding to a saving of 1.4 tons of CO2 emissions compared to the same amount of electricity from the grid.

Hassle free installation

Our professional and polite installers will complete a domestic installation in 1-3 days with no hassle for the home owner.

Virtually maintenance free

Once installed there is virtually no maintenance. On pitched roofs, rain does most of the cleaning. The panels can be expected to last for over 25 years.

Fun!

Many of our clients love their solar PV. It is fun to monitor the generation of your own electricity and become more independent of future increases in energy prices!

How it works

In a solar photovoltaic (PV) system, sunlight generates DC electricity in solar cells which are assembled in solar panels. The panels are connected up in an array which is connected to an inverter converting the DC electricity to AC electricity.

The system connects up to the electric supply and from where all electric appliances in the property can use the generated electricity. When the system generates more electricity than required, the surplus goes to the grid or, if a battery is installed, in to the battery.

A Generation Meter keeps track of the amount of electricity produced by the system.

The electricity from the system is used to run appliances in the property. Any surplus goes back to the grid.

The PV array produces Direct Current (DC) while the electricity from the grid provides Alternating Current (AC). All our installations are grid connected which means that DC electricity has to be converted into AC. This is done by an Inverter.

 
GROUND MOUNTED SOLAR PANELS
  • Panels are mounted on A-frames or pane trays
  • The mounting structure can either be fixed to a concrete foundation or secured with ballast.
Planning permission for ground mounted solar panels:
  • Ground mounted installations always require planning permission, pleas consult your local council

Note – permitted development rights for solar panels are available for both single houses and buildings which consist wholly of flats.

Note – If you are a leaseholder you may need to get permission from your landlord, freeholder or management company.

Roof mounted solar panels – a permitted development provided that:
All the following conditions must be observed:
  • Panels on a building should be sited, so far as is practicable, to minimise the effect on the external appearance of the building and the amenity of the area.
  • When no longer needed for microgeneration panels should be removed as soon as reasonably practicable.
All the following limits must be met:
  • Panels should not be installed above the highest part of the roof (excluding the chimney) and should project no more than 200mm from the roof slope or wall surface.
  • The panels must not be installed on a building that is within the grounds of a listed building.
  • The panels must not be installed on a site designated as a scheduled monument.
  • Wall mounted only – if your property is in a conservation area, or in a World Heritage Site, panels must not be fitted to a wall which fronts a highway.
