Solar Cost for $600 Electric Bill

This is a solar power savings and cost estimate* for a $600 monthly electric bill.

A 20kW or 20,000 watt solar panel system could offset most of your energy use. Results will vary based on utility rate, location and installation factors.

Save $214,856 over 25 years

This is how much money you could save with solar power. Save $540 per month or $6,480 per year after going solar.

The return-on-investment (ROI) is a positive 17% to 27%.

The payback period is 4 to 7 years. The solar panels may work for 25 years or more.

Other benefits of solar power

Be energy independent and avoid utility rate hikes.

Increase your property value by $60,000 to $80,000 depending on where you live. Real estate studies show that a solar home can increase market value at resale.

The environmental benefits are priceless with clean, renewable energy. The solar panels for this size are the equivalent of planting more than 40,000 trees over the system lifetime.

20kW solar system

A 20,000 watt system will use from 50 to 67 panels. The modules can generate around 2,500 kWh of electricity per month on average (varies by location). The solar array will need 1,250 square feet of space on the roof or ground.

How much does it cost?

The average sticker price before tax credit is $34,000 to $54,000 for a grid-tied 20kW solar system.

The NET COST after tax credit could be $25,100 for self-installed DIY, or $40,000 for professional, full-service installation.

The total cost should include building plans, permit, panels, inverter, rooftop mount, installation and warranty.

Electricity Cost before going solar

This is how much you will pay the utility if you don't use solar panels. $600 per month, or $7,200 per year or $246,000 over 25 years. Don't forget inflation! Utility rates go up 4% on average every year.
