Did you ever wonder how long it would take to install solar panels on the roof of your home or business?

The LADWP website reports that once you sign an agreement with a contractor to install solar panels it can take LADWP 3 weeks to review and approve a solar rebate application for a small residential system, or 4 weeks to approve a rebate for a larger system.

Though the actual construction of a solar array can take just a few days, LADWP’s processing goal is for solar contractors to complete the combined permitting and construction process within 56 days for a small system — or 102 days for a larger system.

Once construction is complete, LADWP allows another 2 weeks for inspections.

After inspections have passed successfully, LADWP’s goal is to approve the rebate payment within 6 weeks.

Issuing the rebate payment itself can then take LADWP another 4 weeks.

Most solar contractor handling rebate processing, and will generally wait until the system has been paid for in full, including rebate payment, before activating the system.

In total, roughly 13-14 weeks of the entire process are consumed by LADWP’s handling of rebate payments, representing 45-55% of total installation time. Streamlining (or foregoing) LADWP’s rebate processes could help accelerate solar deployment with the City of LA.
