How to Choose the Right Solar System for Your Home

Choosing a solar system starts with your actual energy use — not only the kW number written on a quotation. Review your recent electricity bills, estimate the appliances you run during the day, and identify the loads that must remain powered during an outage. A proper assessment should also consider inverter limits, roof area, shading, cable distance, battery backup expectations, future load growth and electrical protection. A 5kW or 10kW system can perform very differently depending on the equipment and site. For the best result, combine your monthly units with a site survey and a list of important loads. This gives a much clearer basis for selecting panels, inverter capacity, batteries and protection equipment.
