Choose solar PV panels for residential, commercial and specialist projects, including high-efficiency and bifacial options from established manufacturers. Compare output, module efficiency, dimensions, construction and warranty before selecting a panel for the available roof or mounting area. Panel choice also affects string design, inverter compatibility, handling and mounting requirements, so check the complete electrical and mechanical specification rather than wattage alone. If you are building a full system, pair your panel selection with suitable mounting, PV cable, connectors, isolation and an inverter designed for the proposed array.
