how many kwh do solar panels produce
Electricity is billed by the kilowatt hour. Solar panel energy output is also measured in kWh per square meter of panel surface. The average electricity consumption for a household in the United States is 8900 kWh per year.
Electricity generated can be anywhere between 0 to 6 kWh per day per kW of installed solar power and it depends of geography, time of the year. For a particular geography, total energy (kWh) generated per year can be determined for a year on an average. The lifetime of a power plant is assumed to be around 25 years.
