Disconnecting, dismantling and taking out the non-functional the Solar water heating systems and repair/maintenance following require periodic inspections and routine maintenance to keep them operating efficiently. Also, from time to time, components may need repair or replacement.

Repair and check for Collector soiling Dusty or soiled collectors will perform poorly. Periodic cleaning may be necessary in dry, dusty climates.

Repair and check for Collector glazing and seals Look for cracks in the collector glazing, and check to see if seals are in good condition. Plastic glazing, if excessively yellowed, may need to be replaced.

Repair and check for Plumbing, ductwork, and wiring connections Look for fluid leaks at pipe connections. Check duct connections and seals. Ducts should be sealed with a mastic compound. All wiring connections should be tight.

Repair and check for Piping, duct, and wiring insulation Look for damage or degradation of insulation covering pipes, ducts, and wiring.

Support structures Check all nuts and bolts attaching the collectors to any support structures for tightness

Repair and check for Pressure relief valve (on liquid solar heating collectors) Make sure the valve is not stuck open or closed.

Repair and check for Dampers (in solar air heating systems) If possible, make sure the dampers open and close properly.

Repair and check Heat transfer fluids Antifreeze solutions in liquid (hydronic) solar heating collectors need to be replaced periodically. It's a task best left to a qualified technician. If water with a high mineral content (i.e., hard water) is circulated in the collectors, mineral buildup in the piping may need to be removed by adding a de-scaling or mild acidic solution to the water every years.

Repair and check for Storage systems Check storage tanks, etc., for cracks, leaks, rust, or other signs of corrosion.
