Eligible Solar Water-Heating Systems
Please refer to section 2.2 Equipment Eligibility and Requirements in the CSI-Thermal Handbook (PDF file) for information about eligible equipment.
In order to receive an incentive through the CSI-Thermal Program, installed solar water-heating (SWH) equipment must meet the following criteria:
- Single family residential SWH systems must have a Solar Rating and Certification Corporation (SRCC) OG-300 System Certification;
- Solar collectors used in multifamily residential, commercial, or industrial water heating shall have SRCC OG-100 Collector Certification;
- Components must be new and unused. The only exception is existing de-scaled copper piping which may be reused if it is replacing an existing SWH system;
- System installations must conform to manufacturer's specifications and all applicable codes and standards;
- All SWH systems with the capacity of displacing over 30 kilowatt thermal (kWth)2 (more than 462 square feet of collectors) must have meters or other measuring devices to monitor and measure system performance and the quantity of energy generated or displaced by the system. Please refer to Section 2.8 of the CSI-Thermal Handbook for details on metering requirements.
CSI-Thermal Program will only pay incentives to SRCC-rated SWH systems that displace natural gas or electricity usage. Propane-displacing systems are not eligible for a CSI-Thermal Program incentive.
