Compare solar quotes on more than the total price: check the system’s capacity, expected generation, panel and inverter brands, warranties and estimated payback. Make sure each quote clearly shows whether the price includes design, installation, monitoring, connection fees, warranties and any Small-scale Technology Certificate (STC) discount. Ask how the system will suit your roof, household electricity use and future battery plans, rather than comparing headline panel numbers alone. Before signing, verify the installer’s licence and discuss the quote with the relevant energy provider or a qualified solar professional if anything is unclear.
