Over 30 days, your system would produce about 420 kWh of electricity per month. That’s 420 kWh you don’t have to pay your utility company for. Based on the national average electricity rate of around 14 cents per kilowatt-hour, a 3kW solar energy system could save you an average of about $60 per month on energy bills.
(In other words, don’t expect a 3kW solar system to power an average American home’s lights, electronics and appliances.) Most solar energy companies will tell you that 3 kW of power isn't enough to cover all your electricity use, but adding a 3kW solar system to your roof or backyard can still help you lower your utility bills.
Three kilowatts of solar capacity could power a very small, off-grid home, but it’s likely too little to fully offset the energy use of the average American household. Due to the small size and output, a 3kW solar panel system could be ideal for powering a DIY project.
The number of solar panels you need for a 3kW system depends on the wattage of your solar panels, but you’ll likely need eight to 10 panels if you go with the kinds of panels normally used for residential applications.
