Solar PV Repair & Maintenance

One of the great things about Solar PV is that it doesn’t have a lot of moving parts and so they don't require a huge amount of work to keep them in good working order. Solar panels generally have a warranty of around 25 years with invertors having a warranty of around 5 years for older models and most newer ones up to 10 years. The solar panels on your home don't even need that much cleaning, unless you live in a particularly dusty area or have inconveniently situated bird perches above your panels, we have sufficient rain in this country for the panels to keep themselves pretty clean..

However, if you look after your Solar PV system with regular services you can ensure that you are getting the maximum efficiency and power from your Solar panels, with all the benefits that brings, and make sure that your Solar PV system has a long and happy life, providing you with lots of clean energy and saving you money.

We offer a number of different Solar PV maintenance packages depending on your requirements as well as more in depth fault-finding and repair services.

Solar Thermal Hot Water Repair & Maintenance

Solar Thermal Maintenance
There is nothing worse than not having hot water. Regular 'check-ups' of your Solar Hot Water system will help protect it against the damages of hard water corrosion and ensure that you are kept supplied with plenty of steaming water. You can keep an eye out yourself for fluid leaks (antifreeze has a very strong smell) and keep a check on the pressure (every month or so) to make sure it's still within the manufacturers recommended range however a regular once over will make sure that every aspect of the system is kept in full working order for many years to come. 

4 Yearly Service/Antifreeze change

  1. inspect the solar array for any damage or material failure (if access is available otherwise from ground level visual assessment)
  2. inspect any visible pipework and insulation
  3. check the performance of all system valves and controls
  4. check the circulation of system
  5. test the quality of anti-freeze fluid
  6. Drain down and dispose of old fluid where necessary
  7. Supply new anti-freeze and re-commission where necessary
