Proof of Purchase Requirements
While you may install some of the products yourself, some should be installed using a licensed contractor. The proof of purchase and other documentation required to process your rebate application may differ depending on who completes the installation. All products must be installed prior to submitting your completed forms and other required documentation.
Home improvement contract (HIC) and/or paid invoice/ receipts may be used as proof of purchase. The Contractors State License Board (CSLB) requires that licensed contractors
provide you with an HIC if the materials and labor total for the product(s) and installation is $500 or more. It is recommended that you request an HIC from your contractor even if the contractor installation was less than $500. If an HIC is your proof of purchase, it must be the original given to you by your contractor and must be signed and dated by both you and your licensed contractor. If the signatures are not dated, the date that the HIC was written will determine the product purchase date.
Proof of Purchase must include the following information:
- Retailer or contractor name, business address and phone.
- Itemized description of each product, including such information as:
- Manufacturer, product make and model number(s), and other identifying information, including the ENERGY STAR SWH system ID, ICC/OG-100 collector number, and ICC/OG-300 system certification number.
- Equipment-only cost.
- Solar Uniform Energy Factor (SUEF) for solar thermal systems
- Invoice which includes purchase price per product, and notes “Paid in Full” or lists payment terms if applicable.
- Product installation date, unless self-installed.
- Cash on delivery (C.O.D.) will be accepted as proof of purchase provided C.O.D. invoice is accompanied by a delivery receipt, or an install date is noted on the invoice.
Altered receipts will not be accepted.
