Under optimal conditions, a 1kW solar panel system can generate approximately 4 to 5 units (kilowatt-hours or kWh) of electricity daily. The actual output depends on several factors,
View Details
On average, a 1kW solar panel system can make 4 to 5 units of electricity per day. And it depends on the sunlight it receives. Over a month, there can be around 120 to 150 units of electricity.

Definition: Peak sun hours refer to the number of hours in a day when the solar irradiance averages 1,000 W/m², which is considered the optimal level for solar energy production.
