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.

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.

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, which is also the threshold for the maximum Feed in Tariff (FiT).  Any system size is possible, however, please contact us for a full no-obligation quotation.
