Solar Cell Home Maintenance

Solar power installations are extremely reliable, but like any equipment with a life span of over 30 years, they need to be well maintained.
Almost as important as the design and construction phases of your solar power installation is the process of monitoring your installation regularly. Also from time to time, components may need repair or replacement. You might be able to handle some of the inspections and maintenance tasks on your own, but others may require a qualified technician. Ask for a cost estimate in writing before having any work done.
Following are some suggested inspections of solar system components. Also read your owner’s manual for a suggested maintenance schedule.
Check collector for:-
Shading can affect the performance of solar collectors so check from time to time at different times of the day how shade may affect your panels. Construction on an adjacent property or new construction on your own home may produce shading that wasn’t there when the collectors were installed. Also watch for vegetation growth.
Periodic cleaning may be required as soiled collectors will perform poorly.
Check for cracks in the glazing. Excessively yellowed plastic glazing may need to be replaced.
Pipe connections need to be checked for fluid leaks and all wiring connections should be tight. Check that insulation covering ducts, wiring and pipes has not degraded or been damaged.
Seals where the panels are attached to the roof should be tight as should all nuts and bolts attaching the collectors to support structures.
If you have liquid solar heating collectors make sure the valve is not stuck open or closed.
Make sure dampers open and close properly in solar air heating systems.
Make sure that distribution pumps or fans are operating. They should come on when the sun is shining on the collectors after mid-morning so if you can’t hear them one or the other has malfunctioned.
It is best to use a qualified technician to replace antifreeze solutions which need replacing periodically. He can also check if there is any mineral build-up in the piping and deal with it.
Storage tanks need to be checked for signs of corrosion, rust or leaks.
This may seem like a long and daunting list but these things only need to be checked occasionally and before long you will do it as a matter of course and it won’t seem such a chore.
