Funds will be reserved for your solar system when SRP receives your information, along with the
dealer's quote for system and installation costs. Your system must be permitted and inspected as
required by local code, and installed by a licensed, professional solar installer to qualify for
payment.
If you install a solar electric system, payment will be made upon completion of the interconnection
process (please refer to the documents in Step 1 under "How to apply" above.)
If you install a solar water heater, payment will be disbursed when you submit a receipt for the
completed and installed project.
Please note: An annual spending cap is set for the EarthWise Solar Energy payments. After this
cap is reached, reservations will be taken for next year's funds.
