Before comparing solar panels on the Central Coast, check your roof’s condition, shading, orientation and available space, as these affect the system’s suitability and likely output. Ask each installer about panel and inverter warranties, expected generation, monitoring, installation costs and whether the work will meet Australian standards. The installer should also confirm grid-connection requirements with the local electricity network and explain any Small-scale Technology Certificate discount without presenting it as guaranteed. Compare written quotes from appropriately accredited installers, and consider independent advice if you are unsure about the proposed system.
