FAQ’S

What are PV solar panels?

Solar photovoltaic (PV) panels contain semi-conductors such as silicon, which convert solar radiation into electricity. The electricity produced can be used to run appliances and lighting, and can also be fed into the National Grid or used to charge batteries.

The majority of the systems we install consist of simply bolting the panels to an existing roof. They are mounted on a frame (which makes everything look neat and tidy), and then wired into an inverter. This converts the electricity from DC into AC, at a voltage compatible with the domestic electricity supply.

This electricity feeds the house first of all, and then any surplus electricity is exported to the National Grid, not wasted. From April 2010, you are paid for all the electricity you generate, whether or not you use it.

Is where I live a good place to produce solar power?

Many people will be surprised that the UK is a good place for solar power. However, the panels operate most efficiently in cool conditions, so are perfect for our climate.

Is my home suitable for Photovoltaics?

Photovoltaic (PV) panels can be configured in many different ways to fit different sizes and shapes of roof. If roof space is an issue, another option is to ground mount them on a frame within your garden. Innovative PV array technology and mounting systems means that PV can either be retro fitted on existing roofs, or easily incorporated into new builds.

What is a feed-in tariff?

A feed in tariff is a sum paid by the government to a renewable energy system owner, based on the amount of energy generated. See our feed in tariff page for more information.

How much will PV generate?

A well sited PV system will generate approximately 850 kWh/year per kW installed. So a 2 kW system would generate around 1700 kWh per year, and a 5kW system will produce around 4250 kWh a year.

How much can I earn and save?

One of our typical 3kW domestic systems should cost about £8,000 to install. It will produce about 2575kWh (units of electricity) a year, providing an annual income under the Feed in Tariff scheme of £580*. It would also cut around £150 a year from your electricity bill.

How much will I get paid to generate energy per unit for a domestic system?

You will be paid a guaranteed rate of payment for the electricity you generate (whether the electricity is used or not), currently 21p a unit for domestic systems.

Is there a further payment for the units of electricity that are not used but exported back to the National Grid?

You receive a further payment for every unit of electricity that is not used, but exported back to the National Grid (currently 3.1p in addition to the generation tariff)

How much would I reduce my carbon footprint?

Generating and using renewable energy will significantly reduce your carbon footprint. A 2.5kW system would save 900kg of carbon a year!

Will it supply all my electricity?

The average household consumption is 3300 kWh per year. A 3kW system could supply well over 50% of your electricity over the course of the year.

If and when electricity prices go up, will the amount the Government pay me go up too?

The Feed in Tariff is linked to the RPI (Retail Price Index), which includes energy prices- so as energy bills rise, so will you Feed in Tariff Income.

Will I need planning permission?

No planning permission will be needed for most domestic systems, unless you live in a listed building

How will the installation impact my home?

Once the solar panels are installed on the roof, the inside components do not take up much space inside. Installations usually can be done within 1-3 days depending on the size of the system being installed, with installers being considerate, clean and tidy (have a look at our customer feedback)!

What size solar panel system will I need?

The size of your solar panel system will depend on the space you have available, the amount of electricity you need to produce- and your budget.

How long does a PV solar system last?

A good quality PV system (such as ours) should last 50+ years. PV solar systems installed in the 1960’s are still working at efficiencies of 70% to 80%.

What manufactures do you source your products from?

The manufacturers we use are ethically viable and we consider the environmental impact on using certain companies.

We review our supplier regularly, and will happily provide full details on request.
