A Solar Powered United Kingdom?

Solar panels are a fantastic source of renewable green energy. It is now not uncommon to see them on homes and commercial properties across the UK. There has never been a better time to have them installed. The government backed Feed-in Tariff scheme allows property owners to benefit from more than reduced electricity costs. The Feed-in Tariff allows the owner of the property to get an annual payment for every KWh of electricity they produce and use and a further payment for every KWh that has been produced that is not used and is sold back to the national grid. If you are going to pay out for the cost of having a solar panel system fitted to your property you need to know they are going to last a long time and that the system is covered by some sort of warranty. However, the warranties for solar panels generally fall into two different categories. The warranty for the parts and panels themselves and the warranties for the workmanship.

Workmanship Warranties

It is worth looking around at different companies to see what warranties are on offer as they can vary. Typically workmanship warranties are around five to ten years in length. Obviously you will want the longest warranty that you can find. A workmanship warranty should do what it says and cover for any faults that present themselves over the covered time period. If the problem is directly related to how the system was fitted then this will be covered. Typically problems of this nature will show themselves within a year or two giving you plenty of time to get them back in to correct the work. However, you must read the terms and conditions they have set out very carefully before you decide to have them fit your panels.

Solar Panel Warranties

Solar panels in the UK are exceptionally well made as they are designed to bear the brunt of a British winter. Solar panels very rarely go wrong. Solar panels are covered from anything between twenty to twenty five years. Ideally you need the twenty five year warranty as this is how long the Feed-in Tariff scheme will pay you for. It is not just obvious breakages that are covered by a solar panel warranty. If the efficiency of the panels drops below 80% this will also be covered and the panels will be replaced or repaired. There have been cases of solar panels still working at 8-% efficiency after forty years. The invertors are usually warranted for five years at a time.

Home Insurance

Remember that not all things will be covered with the warranties. If the damage to the solar panels has been done by a fault in your roof that is not related to the presence of the panels then the cost for repairs may have to be covered by your home insurance. Solar panels should be added to your home insurance when you decide to have them fitted. Although the roof will be checked thoroughly by the company that fits the panels to make sure they are strong enough you may have to have the panels removed for repairs to your roof at a much later date. This should be covered by your home insurance. In general it is best to go with the company that offers the best and longest warranty available and check very carefully exactly what the warranty covers.
