When you can cancel
There are a few common moments when cancellation is possible. Before you sign, you can decline any quote. After signing, your rights depend on the contract language and whether state law gives you a cooling-off window. If a system is third-party owned or financed, the finance company or lease owner may have separate rules. Also keep in mind that approvals, permits, and interconnection steps can affect timing — once permits are pulled or equipment is ordered, it can be harder to reverse course without fees or delays.
How cancellation can change price and timing
Cancelling can affect what you pay and how quickly you can move forward later. You might lose part or all of a deposit, or be charged for work already done like roof prep or permit fees. If you ask a different company for a new quote, expect numbers to change because every roof, inverter choice, panel brand, and local permit cost is different. Financing terms can also shift: a loan or lease offer you had may not be available later. Finally, incentives and utility interconnection timelines can change while you wait, so cancelling and re-starting may add delay.
What to check in your contract before cancelling
Read the cancellation clause first. Look for language about deposits, refund windows, and fees related to work already performed. Check how financing or third-party ownership is handled — loans, leases, and power purchase agreements often include separate termination rules. Note who is responsible for permits and inspections, who owns any renewable energy credits, and whether warranties transfer. If anything is unclear, ask for a plain-language explanation in writing.
How to cancel and practical next steps
If you decide to cancel, start with a written notice to the installer and any finance provider. Request written confirmation of the cancellation and any refund timeline. Keep records of emails, receipts, and permit status. If a deposit or fee is disputed, review the contract and consider escalating: ask for a clear itemization of charges, contact your bank if you paid by card, or consult a consumer protection office if necessary. After cancelling, get several new quotes and compare the same components — system size, panel and inverter brands, permit handling, estimated production, and financing terms — so you can make a fair comparison next time.
