Most residential solar panels today range from 300W to 450W. Higher wattage panels mean fewer units are needed to reach 3kW. For example, using 300W panels, you would need approximately 10 panels to generate 3kW. If using 400W panels, only 8 panels are needed. [pdf]

A 10kW Solar Kit requires up to 650 square feet of space. 10kW or 10 kilowatts is 10,000 watts of DC direct current power. This could produce an estimated 1,350 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the solar array facing South. [pdf]
How much energy does a solar panel produce? On average, a solar panel can output about 400 watts of power under direct sunlight, and produce about 2 kilowatt-hours (kWh) of energy per day. Most homes install around 18 solar panels, producing an average of 36 kWh of solar energy daily. [pdf]
