Solar Panel Service | Solar Maintenance

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

Over time in solar water heating panels, 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 solar hot water 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Software may need to be updated on the controller if it’s outdated.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.

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
