When comparing solar quotes in Canberra, check that each proposal uses the same system size and clearly lists panels, inverter, mounting, installation and any battery costs. Ask about estimated annual generation, likely savings, feed-in tariff assumptions, warranties, monitoring and whether the installer will manage ACT electricity-network approval. The final price can vary with roof access, shading, switchboard upgrades and the number of small-scale technology certificates (STCs) available, so advertised figures may not apply to every home. Compare several detailed quotes and verify the installer’s credentials before signing.
