Why a 9kW Solar System with Batteries Could Be Overkill (Or Perfect) for Your Home
Calculate your actual energy consumption before committing to a 9kW solar system with batteries. Pull your last 12 months of electricity bills, add up the total kilowatt-hours used, and divide by 365 to get your daily average. Most households consuming 25-35 kWh daily find a 9kW system hits the sweet spot between coverage and cost,…
