Solar PV panels FAQ


Q. What is a solar PV system?

A solar photovoltaic (PV) system is an array of panels, typically situated on a building?s roof space, that convert sunlight into electricity, which is directly fed into your property?s electricity supply.

Q. How does a solar PV system work?

Solar PV panels convert light into electrical power using a thin layer of semi-conducting material, usually silicon, encased between a sheet of glass and a polymer resin. When exposed to daylight, electrons in the semi-conducting material become energised. These electrons are then able to flow through the material generating a direct current (DC). The DC is carried through wiring to an inverter, which converts the current to 240V alternating current (AC), so it can be connected to your home?s mains electricity supply. There are a number of factors that determine the suitability of your home for solar PV:

Q. Is my home suitable for a solar PV system?

The positioning of your roof:
You will need a roof space on which to install the panels that is within 90 degrees of south and isn?t overshadowed by trees or buildings.
The strength of your roof:
You will need a roof robust enough to withstand the weight of a solar PV system. Solar panels are not light and the roof must be strong enough to take their weight.
Planning permission:
If your home is a listed building, in a conservation area or a World Heritage Site, you will need to gain permission from the relevant planning authority. However, for most homes in England and Wales, a solar PV system is considered as a ?permitted development? under the current planning laws and planning permission is not required.
Electricity supply:
Your home will need to have an existing electricity supply from the National Grid.

Q. Does solar work in the UK?

Solar panels work using light but don?t necessarily need a sunny day to operate, as long as the sun is pointing toward the panels they will work . They are able to function in cooler and cloudier climates, though they are more efficient on sunny days.

Q. How can I earn an income from generating my own electricity?

The Government launched something called a ?Feed in Tariff? on April 1, 2010. Under this scheme energy suppliers must pay householders who generate their own electricity using solar PV systems. The Feed in Tariff is designed to encourage more people to generate solar electricity and contribute to the UK?s aim to reduce its carbon emissions by 50 per cent .The tariff guarantees a minimum payment for each kilowatt of electricity generated (generation tariff ) and a further payment for any surplus electricity that the PV panels create that can be exported back to the National Grid to be used elsewhere (export tariff).

Q. How much can I earn?

Feed in Tariffs are subject to a Government review every three months, so the sooner you have a system installed the better the returns will be. Speak to one of our advisors for current rates and projections of what your property could earn for you by calling link to contact.

Q. What are the benefits of generating my own electricity?

? Reduce your electricity bills significantly
? Earn a generous tax-free income from the FIT tariff (2 incomes made up of the generation tariff and export tariff)
? Combat rising fuel costs (FIT is index linked)
? Reduce your carbon footprint

Q. Do I still own the solar panels if I move home?

The solar panels, once installed, are considered a part of the property in a similar way to insulation and other home improvement measures. This means that, if the home ownership changes, the ownership of the panels are transferred to the new owner. This is the case for all solar PV installations.

Q. How long will my system last?

Solar systems have a long lifespan in general and systems generally have a manufacturer?s warranty of 10 years, though this is usually exceeded by quite a number of years. System performance will be guaranteed for 20 years under the Feed in Tariff.(panels must produce at least 80% of original capacity after 25 years.
