A 30kW solar system is a large residential or commercial-sized array that can produce a substantial amount of electricity. The daily energy output varies depending on the location, ranging from 100kWh in Hobart to 127kWh in Perth. Under optimal conditions, a 30 kW system can generate approximately 30,000 to 40,000 kilowatt-hours (kWh). . Estimate daily, monthly, and yearly solar energy output (kWh) based on panel wattage, quantity, sunlight hours, and efficiency factors. Losses come from inverter efficiency, wiring, temperature, and dirt. The biggest the rated wattage of a solar panel, the more kWh per day it will produce. How Much Sun Do You Get (Peak Sun Hours). Example: In a sunny region like California, a. .
