kW measures the maximum output by a solar panel system.
Solar panel systems with higher kW output generate more renewable electricity.
Actual output is determined by local weather, orientation, and shading.
Under ideal conditions, 1 kW of install capacity will produce 1,200 kWh of renewable electricity.
To compare, the average family uses 9,000 kWh to power lights, electronics and appliances over a year.
Electricity generated by a solar panel system can be used immediately or stored in batteries.
With Utility approval, excess electricity can be fed into the grid and used to reduce energy bills.
