When comparing solar quotes in Brisbane, check the system size, panel and inverter brands, estimated annual generation, and whether installation suits your roof orientation and shading. Make sure each quote clearly separates equipment, labour, switchboard work, monitoring, approvals and any battery costs, and explains how Small-scale Technology Certificates (STCs) affect the price. It is sensible to compare several detailed quotes and check that the installer is appropriately licensed and using current Clean Energy Council accreditation requirements. Ask about product and workmanship warranties, then confirm the final design and terms directly with the installer before signing.
