One of the reasons that solar panels are such a good investment is that they require very little maintenance. Most solar panel systems are fine with basic checks and occasional cleaning We may even suggest that solar panels do not need to be cleaned as they have self-cleaning glass which removes any residue or debris when it rains. However, solar panels are only cost efficient when they are working at maximum output and for that reason it is best to visually check them at least once a year. If moss is growing on the bottom edge it will become a problem once it grows over the edge of the nearest cells. All that is needed is a soft brush and some clean water, do not use any detergent.
A hose pipe is the best way to clean the panels, do it when they are cool in the morning or evening to avoid cracking the toughened glass.
When you have an inverter installed, usually in the attic, you should ensure that it will not be subjected to damp or hot conditions as this could lower its lifespan. The most easy thing is to check that the input and output displayed on the inverter is accurate to what your system is actually producing.
All of these maintenance checks can be made yourself, however, if in doubt it is always better to bring in a professional service. This is particularly important for dealing with electrical systems and working at heights. These can be dangerous situations for those unqualified to carry them out safely.
Solar P.V. System repairs
It is very unlikely that the solar panels themselves will have to be repaired. It is more likely that the inverter or other parts of the system need to be repaired. If there is an issue with the inverter, or you notice any cables are damaged, it would be classed as an electrical problem. In this situation, you should only allow a qualified electrician, with solar power experience, to assess and repair any damage.
Do not attempt to fix any problems yourself if you are not qualified to do so. Not only will the high voltage DC be potentially very dangerous, but you could also void your warranty agreement. Many warranties and solar panel contracts state that only qualified professionals should attempt to repair the system in order for you to remain within the terms and conditions.
Cost of solar repairs
The cost of maintaining solar panels is not high compared to their potential income from energy bill savings and Feed-in Tariff payments. The first thing to do is check with your original installers, as they may offer a repair under warrantee or at a discounted rate. The next thing to do if they cannot or will not help you is to give us a call or use the contact form on this site. Our charges are £50.00 for the first hour and £35.00 per hour thereafter, plus parts as necessary. If an access tower is needed then the job will require two men to build and dismantle it and the charge is per man. Some inverters are extremely heavy and will also require two men to remove and reinstall them.
