Why should you service your Solar Panel System?

Please note we only service our own Solar Thermal installations.

Solar Panel Service is crucial, if the system is to operate correctly.

 

  • Over time, the antifreeze breaks down and may freeze during a harsh winter. When the antifreeze is broken down, it turns to the consistency of syrup and becomes difficult to pump.
  • Temperature sensors can become faulty and can give false readings if they are heated beyond their limits.
  • Sensors can sometimes be pulled out of the correct location in the cylinder by a falling towel if they are not secured properly.
  • Software may need to be updated on the controller if it’s outdated.
  • Non return valves may become clogged with dirt if the antifreeze is not changed regularly. This can lead to heat loss at night time.

A full solar service from AEI includes:

  • Power flushing of the solar circuit to remove sludge and debris
  • Change of antifreeze fluid to new antifreeze
  • Examination of internal pipe and electrical connections in the solar system
  • Examination of electrical connections in the solar controller
  • Confirm the correct operation of all controls
  • Setting the correct pressure inside the expansion vessel
  • Calibrate the pump flow rate to suit the solar panels on site
  • Setting the correct antifreeze pressure in the system
  • Confirm the correct settings are set on the controller
  • Check the valves in the system are rotating correctly
  • A commissioning certificate can be issued for your records after payment is received

Please note the following is not included in a service:

  • Roof access
  • Repairing a leak
  • Parts, other than the required antifreeze
  • Anything outside of the above items that we do cover, are chargeable
  • Generally an estimate for a repair cannot be given in advance of the visit as we need to see the issue
