SHW Inspection Checklist
General Information
1. Note the date and time of the inspection.
2. Note the sky cover and temperature during the inspection.
3. Provide an irradiance measurement in the plane of the collectors.
Equipment Inspection
4. Verify manufacturer and model numbers from the solar collector nameplates. If the
nameplates are inaccessible, use invoices from the installer.
5. Verify that the collectors are SRCC-OG 100 listed. An SRCC-OG 100 label must be attached
to each collector. Record the Clear Day Rating Category, kWh/day, kBTU/day, and Gross
Area as specified on the SRCC-OG 100 label attached to each collector.
6. Identify the type of collector (flat plate or evacuated tube).
7. Note the number of collectors and the total square feet of collector area.
8. Verify that the collector and all components have been installed according to the
manufacturer’s instructions.
9. Determine the tilt and azimuth of the collectors.
10. Is the system protected from freeze damage? If so, how?
11. Does the system have adequate control against overheating?
12. Are the collectors properly supported?
13. Are the collector mounting brackets securely and properly attached to the mounting surface.
14. Are mounting materials non-corrosive?
15. Are surface penetrations properly attached and sealed?
16. Are collector sensors properly attached and sealed?
17. Is a pressure relief valve present and drained in a safe direction?
18. Perform a shading analysis using a Solmetric SunEye, Solar Pathfinder, Wiley Asset, or
equivalent tool.
19. Calculate the system performance based on the shading analysis and the system siting
parameters.
20. Confirm that the system provides hot water only to the hot water storage tank(s). Verify that
the system does not provide hot water to a swimming pool or hot tub.
21. Note whether the collector is located on the building roof or an accessory structure. Provide
photo verification.
22. Note the size, make and model of the storage tank(s).
23. Note if an auxiliary tank or heater is present. If so, indicate the fuel type that operates it.
(electric, natural gas, etc.)
24. Are the tanks properly plumbed?
25. Are the tanks accessible for maintenance?
26. Does plumbing allow bypass of the solar system?
27. Do the tanks have the capability to set an upper temperature limit to protect from damage
and injury? If so, is it properly set?
Attachments
1. Provide photos showing the solar collector(s) location and size.
2. Provide at least one photo of the SRCC-OG 100 label for each type of collector utilized.
3. Provide photos showing the hot water storage tank(s).
