     To maintain your system in top form and keep your warranty in good standing, there are certain aspects of your system that need to be checked and occasionally maintained.  That is why we have created an easy program to help our customers make sure their systems are running at peak efficiency.

     We recommend that you use these inspection checklists for Solar Hot Water and Photovoltaic systems.

Solar Electric and Battery Backup Systems

  1. Clean and inspect each individual solar module and check for possible shading
  2. Clean roof panels
  3. Torsion check on each piece of rack mounting and attachment hardware
  4. Evaluate flashing
  5. Inspect each module connection in series
  6. Check entire racking system
  7. Assess combiner and junction boxes for inspection
  8. Inspect conduit run
  9. Clean inverter fans if necessary
  10. Inspect PV system disconnect
  11. Check power output
  12. Record Charge Controller Log
  13. SPV Test - Overall system performance verification

           Systems with Batteries           (Backup and PV)
  1. Make sure you have the right tools and safety equipment (gloves, goggles, baking soda, wrenches, battery tester)
  2. Monthly Check of Batteries
  3. Measure and record voltage and specific gravity for each battery (after sufficient rest period)
  4. Check level of acid in each cell of each battery and top off with distilled water
  5. Perform a load test on each of the batteries
  6. Clean and apply grease to the connections
  7. Check and tighten all connections of the batteries, inverter and EPanel
  8. Perform a battery equalization process
  9. Check each 110v leg of the 220v entering and leaving the inverter to make sure the system is in balance
  10. Revision of all wires throughout the system for wear, heat and connectivity
  11. Revision of Inverter Settings
  12. Revision of the charge controller, voltage and amps entering and leaving

 

Solar Hot Water
  1. Inspect collector/s for damage or wear and possible shading
  2. Clean collectors panels
  3. Test roof top relief valve for proper function and ensure pressure seating
  4. Check small PV panel
  5. Service pump if necessary and check flow/performance
  6. Examine expansion tank and recharge if necessary
  7. Check for leaks
  8. Exercise mixing valve and check diaphragm to insure proper function
  9. Test system running pressures/temperatures and accuracy of gauges
  10. Check tank anode for corrosion
  11. Test Check Valve for directional control
  12. Check back-up elements and thermostat on Solar tank
  13. Inspect all insulation for deterioration/wear/weathering
  14. Annually flush collector/s
