Energy from the Sun
What Does a 100kW PV System Mean?
• As the sun rises the photovoltaic cells begin to produce electricity at a low level
• At noon a 100kW system is producing at its optimum output
• In California the average is 5 peak sun hours a day
• Therefore, we could say that this 100kW system produces 500kWh/day (100kW x 5 hours =
500kWh)
• Depending on your energy usage profile a 100kw system could produce all or part of your total
energy needs
