Search for local installers with the right electrical licences and relevant solar accreditation, then compare several written quotes rather than choosing on price alone. Check the proposed panels, inverter, installation method, warranties, after-sales support and whether the installer will manage grid-connection paperwork. You can also look for customer reviews and ask for evidence of insurance and recent local work. Eligibility for any incentives or certificates depends on the system, installer and your circumstances, so confirm current requirements through the official government guidance and your electricity distributor.
