What does a typical PV system look like?
• How is power measured from a PV or solar electric power system? • The capacity of a PV system is stated in terms of the number of watts, kilowatts or megawatts it produces in standard sunlight conditions. A good estimate for New York is that each kilowatt of PV capacity (alternating current) will produce approximately 1,000 to 1,300 kWh (kilowatt hours) per year, depending on the angle at which the solar panels are mounted. Thus, a 3 kW system will generate about 3,000-3,900 kWh per year, or about 50-60 percent of the average residence’s electric consumption.
