When comparing solar quotes on the Central Coast, check the system size, panel and inverter brands, estimated annual generation, total price and whether GST, installation and any meter or switchboard work are included. Ask whether the installer is accredited and confirm the proposed system will meet your electricity needs, roof conditions and local network requirements. Quotes may account for federal Small-scale Technology Certificates, but the value and final price can vary. Review product and workmanship warranties carefully, and compare several written quotes before choosing an installer.
