For an SDG&E homeowner comparing a solar-plus-battery PPA, ask for the completed Solar Energy System Supporting Information document alongside the contract. It gives you a useful place to check how the proposed agreement and savings assumptions have been recorded. Review the completed version for your project, not a blank sample.
A qualifying no-upfront-cost offer can help an eligible household access solar and battery equipment without buying the system upfront. Clear supporting paperwork helps you understand that offer’s ongoing costs and the backup equipment included.
Know which documents you are reviewing
The CPUC’s disclosure-document page identifies two documents: the Solar Energy System Disclosure Document cover page and the longer Solar Energy System Supporting Information document. It says customers must receive these before signing a contract and that both, or accepted versions, are required for a complete solar interconnection application.
The CPUC identifies Version 2 of the supporting document as the version to submit. Its guidance distinguishes this paperwork from the separate Solar Consumer Protection Guide. Ask your provider to identify each document rather than treating every signature page as interchangeable.
Check the PPA and battery entries
The CSLB supporting-information form includes PPA entries for the energy rate, annual escalator, upfront payment and monthly payments where applicable. It also records the agreement term and points to contract details about transfer, warranty and maintenance.
Its savings section includes annual electricity usage, estimated solar generation, battery capacity, minimum state of charge and electricity rate schedules before and after installation. The form explicitly describes estimated savings as a guide rather than a guarantee.
Our recommendation is to compare those completed entries with the proposal you are considering. Ask the provider to explain differences and give you a consistent final set of documents before you sign.
For a hypothetical example, suppose a revised proposal adds a second battery but the supporting paperwork still describes the earlier configuration. Request a review of the affected entries and calculations. This is a document-consistency example, not a prediction that adding a battery will save a particular amount.
Keep the SDG&E process in view
SDG&E’s installation center directs customers and contractors to submit solar and battery interconnection applications through DIIS. Ask who will assemble the final application and how you will receive copies of the submitted documents.
Financial disclosure does not itself authorize installation or operation. Keep the utility’s project milestones separate from your contract review. Our SDG&E installation-date guide explains questions to ask when the proposed schedule changes.
Review the full payment and backup commitments
The CPUC solar guide explains provider ownership and continuing payments for electricity under a PPA. Confirm qualification, rate, escalator, term, any upfront or separate battery charges, battery ownership, maintenance and transfer provisions. Utility charges can remain. No upfront purchase does not mean free electricity or guaranteed savings.
A completed savings form also does not establish outage runtime. PG&E’s general battery guidance explains that supported circuits, stored energy and demand constrain backup. Ask for your actual circuit list and runtime assumptions. Ordinary grid-tied solar alone generally does not provide outage power; solar recharging during an outage needs compatible backup equipment and suitable sunlight.
