A quote should include: solar panels, string or micro inverters, mounting hardware and racking, DC and AC wiring, safety disconnects, electrical panel upgrades if needed, municipal building permit, provincial electrical inspection, Hydro-Quebec interconnection paperwork, labour, and warranty documentation.
