PV FAQS

What are Photovoltaic (PV) Panels?

Solar Photovoltaic panels convert sunlight directly into electricity that can be used to run appliances and lights. Photovoltaic cells generate energy even when it is overcast and cloudy as they absorb scattered light.

How are PV panels fitted?

Photovoltaic panels can be mounted on a roof or ground mounted. Ideally the roof will be south facing, or near to at an angle of 30 degrees with the horizontal for optimum performance. The panels produce DC electricity, so a small inverter will be fitted inside the house, to change the DC into AC (used in all normal homes and on the National grid). Installation is clean, with minimal disruption and no extra space needed indoors.

How many are needed?

Any number of PV panels can be connected based on available space, to provide as much electricity output as required. A basic 2kWp solar panel installation will generate around 1600 kWh per year.

How much do they cost?

The price will vary depending on the size of individual installations. Please fill in our enquiry form or call us on 0800 211 8090

What Maintenance and installation is required?

As there are no moving parts in the PV panels, there is no noise or need for maintenance other than an occasional clean as required. Solar panels come with a warranty of over 20 years. During installation of roof systems, scaffolding is required, installations usually take around three days to be completed.

What is the Installation Process – what do I need to do?

For a typical domestic system we supply, install and test all of the equipment, we arrange the scaffolding, notify your district network operator and will provide you with all the warranties and certifiactions you require to receive the feed-in tariff. All you will need to do is contact your electricity supplier and ask for a microgeneration pack and then relax whilst we do the rest. Once installed, you will have all the information to fill in on your pack and send back to your supplier to receive your feed-in tariff and start saving and earning money.

Can I really sell back to the National Grid?

Yes. The April 2010 Feed-in Tariff will pay a premium on every unit of electricity generated by Solar PV panels with an additional bonus for every unit of electricity exported back to the National Grid. This is paid for everything you generate regardless of whether you use it in the property. This Tariff will be administered by Ofgem. Electricity suppliers will be responsible for paying the reward directly to customers.

Do PV Panels Work In The UK?

Generally temperatures above room temperature reduce the efficiency of PV Solar panels, making the UK a good climate for photovoltaic technology. The panels require ambient light rather than direct sunlight to generate electricity so they work even on overcast days.
