Do solar PV panels require any maintenance?

Generally no, although an inspection by a certified Solar PV installation company every 5 years may offer you reassurance. See our page on Solar PV Maintenance.

Do solar PV panels require cleaning?

No. Solar Panels above a slope angle of 15 degrees (i.e. most solar panels) are deemed to be self-cleaning. See our page on Solar PV Maintenance.

Do I need planning permission?

Unless your building is in a conservation area you do not usually require planning permission. In all cases we recommend that you speak to your local authority to confirm you individual situation.

Contact us for further information or see the Energy Saving Trust website.

How long will it take to install Solar Panels?

This depends on the Solar PV system type and size of installation, along with the specific requirements of your site installation, but generally between 2 to 4 days.

Is my income guaranteed?

From the 1st January 2020 you will need to shop around for the best price to sell your solar energy. Find out more about the Smart Export Guarantee scheme.

How much will it cost?

This depends on the system type and size, and can vary according to the specific requirements of your individual installation, but generally it will vary between approximately £3,000 and £8,000 for systems ranging from 2kWh to 4kWh.

How long do solar panels last?

Solar panels generally do not fail, and are guaranteed not to do so for 25 years. However, they do gradually lose efficiency over time, for which they are guaranteed not to drop below 90% efficiency after 10 years and 80% efficiency after 25 years. You can expect a good long term investment from the Solar Panels that we fit to your roof, especially with pay back periods between 7 – 10 years.

What kind of guarantee do they come with?

Our solar panels are guaranteed for 25 years, with an efficiency guarantee of 90% after 10 years and 80% after 25 years. The inverter – the most sophisticated component of a Solar PV installation – is guaranteed for 5 years, but this can be extended up to 25 years.

Can I improve the efficiency of my Solar PV Panels?

Indirectly – by fitting a Voltage Optimisation energy efficiency system it is possible to reduce the energy consumption of your house. The incremental cost of doing this at the time of installing your Solar PV System is relatively low. Find out more…

What size system can I have?

This depends on various factors such as the space available, whether you want to try to reduce your energy bill to zero or just offset it, and the budget you have available. Generally, on a domestic property, the maximum installation size is up to 4Kwh.  Any system size is possible, however, please contact us for a full no-obligation quotation.

Will fitting solar panels to my house add to its resale value?

Yes. Given the income available through exporting your energy and the long life of Solar PV installations, people are attracted to houses with Solar Photovoltaics installed. Some people may need a little help to understand solar PV but the handy post-installation pack that we give to each customer will certainly help.

Can you fit solar panels over soil pipe vents in my roof?

If you have a small brown mushroom on your roof that acts as a soil pipe vent, this can be replaced by a low profile vent tile and solar panels fitted over the area.
