What to ask before signing with an installer

Ask for the installer's electrical registration and confirm the certificate of compliance is included in writing. Ask who issues it and when you receive it.

Ask what the warranty covers separately for panels, inverter, batteries and workmanship — these are almost never the same length.

Ask what happens if the system underperforms against the estimate they gave you, and get the answer in the quote, not in a WhatsApp message.
