California Code, Public Utilities Code - PUC § 2851.5

(a) A school district or community college district may request an extension of a reservation expiration date for monetary incentives for a solar energy system. The commission may grant a maximum of three extensions of 180 calendar days for each extension.

(b) An extension request pursuant to subdivision (a) shall be made in writing, submitted to the program administrators, and shall include a written explanation of the need for the extension and the amount of additional time needed. In describing the need for the time extension request, the school district or community college district shall provide information on the circumstances, that are beyond the control of the district, that prevent the solar energy system from being installed as previously described in the initial reservation request. A failure to submit the incentive claim form package by the original or extended reservation expiration date shall result in the cancellation of the request.

(c) An approval of a request for a change in the reservation expiration date for monetary incentives for a solar energy system shall not modify any other condition of a reservation for incentives.
