Solar Panel Servicing
In order to keep all solar panels systems working at its optimum it should be serviced regularly. All customers who have installed a solar panel system by Solar Home get the benefit of having the first 5 years of solar panels maintenance for free!
Our staff have been initially trained in Germany with Phoenix Solar and because of their strong technical background we are also able to offer servicing and repair to all other makes of solar panels. If you have a solar panel system that you think may not be working correctly or has not been serviced since it was initially installed give us a call today to book a service. Typically your solar panel system should be serviced every 2 years to ensure that the system is working at its optimum. As part of our standard service we carry out the following solar panels maintenance checks:
Solar Panel Repair
If you have a solar panel system installed that you feel is not working correctly this can be because of a number of problems to do with the way the system has been installed or the possibility of a defective component. If you would like to talk to us about this feel free to give us a call to arrange an appointment. Some of the common issues that we find when repairing other companies solar panel systems are:
Antifreeze leak on the system
Incorrectly specified pressure release valve
Incorrectly sized pressure vessel
Incorrectly specified pressure vessel
Replacement of faulty sensor wires
Replacement of antifreeze
Installation of solar non return valves
Correct reposting of sensor wire
Replace substandard insulation
Re-programming of the solar controller
Seal leaks on joints on the system
Solar panel systems are usually a pressurised closed loop set up, if the system has dropped in pressure this will need to be re-pressurised.
The flow rate that the system is set at his a large effect on the overall performance of the system. If the flow rates are too fast the system will keep starting and stopping during typical operation, if to slow the liquid will not flow through the panels quickly enough causing the system to overheat prematurely leading to an early shut down while the hot water cylinder still has the potential to heat the water to a higher temperature.
We use accurate test equipment to test the freeze temperature of the antifreeze contained within the solar panel system. We recommend that this is set at -25C to prevent any potential problems with the system during harsh weather conditions.
We use a manometer to check the pressure in the vessel if this has dropped we re-pressurised the vessel. Air Venting: If your system was incorrectly commissioned air will begin to build up within your system this will have an adverse effect on the system performance. In extreme conditions the air will form a large pocket within the system loop causing the system to air lock. If this occurs the system cannot heat the water in the cylinder. As part of our service we vent the system and manually over ride your control panel running the system to check for air pockets
