Common questions
What if the system works but savings are lower than promised?
Keep the sales projection, actual bills, generation records and any explanation from the installer. The issue may be about the promise rather than total system failure.
Should finance documents be included?
Yes. Solar disputes often involve both the installer and finance provider, so keep the credit agreement, payment records and lender replies.
What if the installer has stopped trading?
Keep company details, proof of payment, warranties, finance documents and failed contact attempts. Those records may help identify the practical complaint route.
