What should be attached to a solar contract?

At minimum, retain the complete contract, proposal, equipment schedule, layout, warranties, financing disclosures, payment schedule, and any addenda or change orders.

Do verbal promises count?

Do not assume they will. Put every material promise into the signed documents and seek legal advice if the written terms conflict with what you were told.

Can I cancel a solar contract?

Rights and deadlines depend on the transaction and applicable law. Read the stated cancellation process immediately and contact a qualified local adviser if uncertain.

A proposal summarizes the offer; the contract allocates rights, duties, timing, payments, and risk. Read the contract and financing documents together, save complete copies, and seek qualified legal advice for questions about enforceability.

Identity, scope, and price

Confirm the legal names and contact information of the seller, installer, lender or system owner, and subcontractors. Match the cash price, financed amount, system size, exact equipment, layout, included electrical and roof work, permits, interconnection, and cleanup.

Exact panel, inverter, battery, and racking models and quantities.
Itemized price and payment milestones.
Responsibility for permits, utility approval, structural work, and main-panel changes.
Rules for equipment substitutions and change orders.

Timing, cancellation, and performance

Find the cancellation procedure, start and completion conditions, delay language, permission-to-operate responsibility, production representations, and remedies. Do not rely on a verbal completion date or savings guarantee that the contract disclaims.

Financing, warranty, and transfer

Reconcile the contract with lender disclosures or third-party ownership terms. Check liens or security interests, prepayment, payment changes, transfer on sale, insurance duties, maintenance, warranties, dispute terms, and end-of-term obligations.
