Solar System Repair / Maintenance /Cleaning

 

Just purchased a home or commercial building and the solar PV system is not working. Solar Choice USA can repair, maintain, upgrade and clean systems we install, and we can also service and repair Solar PV Systems installed by third parties. We cannot currently service or repair Solar Thermal Systems fitted by other companies.

Solar energy systems require periodic inspections and routine maintenance to keep them operating efficiently. You might be able to handle some of the inspections and maintenance tasks on your own, but others may require a qualified technician.

Periodic Solar Inspection List

 

Here are the most frequent problems experienced by solar system components. Also check the manual for a suggested maintenance schedule.

  • Connector.

    Solar Panel Collector shading

    Visually check for shading of the collectors during the day (mid-morning, noon, and mid-afternoon) on an annual basis. Shading can greatly affect the performance of solar collectors. Vegetation growth over time or new construction on your house or your neighbor’s property may produce shading that wasn’t there when the solar panels were installed.

  • Connector.

    Collector soiling

    Dusty or soiled solar panels will perform poorly. Periodic cleaning may be necessary in dry, dusty climates.

  • Connector.

    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.

  • Connector.

    Wiring connections

    Look for corrosion on connections. All wiring connections should be tight.

  • Connector.

    Piping, duct, and wiring insulation

    Look for damage or degradation of insulation covering pipes, ducts, and wiring.

  • Connector.

    Roof penetrations

    Keep an eye out for leaks in the ceiling. Flashing and sealant around roof penetrations should be in good condition but after years can fail.

  • Connector.

    Support structures

    Check all nuts and bolts attaching the collectors to any support structures for tightness. At high angles solar panels can slip out of position due to wind.
