Solar Contractor Eligibility

License Requirements

Contractors must have an active A, B, C-4, C-36 or C-46 contractor's license and be in accordance with all Contractor State License Board (CSLB) rules and regulations. For more information regarding California licensing requirements please visit the Contractors State License Board website.

Training Requirements

Prior to participation, contractors must attend a half-day CSI-Thermal program workshop. The workshop provides specific details regarding eligibility and application submittal. The CSLB license holder must attend the workshop to receive eligibility. All other employees affiliated with the CSI-Thermal process are encouraged to attend as well. Upon completion of the workshop, the CSLB license holder will be provided with a "key" to access the CSI-Thermal application database and begin submitting incentive applications. Database keys will not be provided to anyone other than the contractor license holder as listed on CSLB website. However, once the contractor has registered in the database, there will be the option to create new profiles for other users in the company. Once registered, companies will be added to the Eligible Contractor List. To register for an upcoming workshop, please visit our solar classes search page.

Self-Installer Eligibility

Self-installations are permitted in the CSI-Thermal Program. Homeowners or building owners who choose to install a solar water heating system on their property must attend a half-day CSI-Thermal Program workshop. This training is intended to familiarize self-installers with program rules and requirements, however, it is not meant to serve as an introductory course on basic solar thermal installation. Self-Installers must install their solar water heating system within 12 months of attending the required training. To register for an upcoming workshop, please visit our solar classes search page.

End-Use Eligibility

Single-Family

In single-family applications, all Domestic Hot Water (DHW) end uses are eligible in the CSI-Thermal Program. DHW is defined as water used, in any type of building, for domestic purposes, principally drinking, food preparation, sanitation and personal hygiene (but not including space heating, space cooling, or swimming pool heating).

Multi-Family/Commercial

To be eligible, solar water heating applications must directly consume the solar heated potable water, as opposed to using the solar heated water as a medium to carry heat for some other end use. In multi-family/commercial applications, DHW and commercial end uses are eligible for CSI-Thermal Program Incentives.

The program may expand to allow other end uses such as space heating and cooling at a later date.

Equipment Eligibility
