Field Inspection Process and Checklist

A portion of all CSI-Thermal Program projects are subject to onsite field inspections at our discretion. For each eligible contractor, the Program Administrators will conduct an onsite field inspection for the first three submitted Incentive Claim Forms that displace 250 kWth or less and the first three Incentive Claim Forms that displace more than 250 kWth. Program Administrators will inspect a random sample of projects thereafter.

The CSI-Thermal Program inspection checklist (XLS, 64 KB) is a guide for installers and customers that describe in detail the areas that are examined during a field inspection. This is a very useful tool to ensure that the solar water heating system matches the final documentation submitted for the incentive.
