Solar Panels For Homes

How Many Solar Panels To Power My Home?

Most homeowners seek to eliminate their electricity bill by switching to solar energy. So to find out how many solar panels you need to power your home, you would need to determine how to meet the amount of energy you use with solar energy.

To find the correct amount of solar panels for your home you should find out how many kWh of energy you use. You can call your electricity company or find this amount in your monthly energy bill statement. (1kWh=1,000 watts of power per hour).

Here’s a simple way to figure out your ideal solar panel system size:

kWh per month / (avg sunlight per day * 30) = kW solar system

You’ll most likely be working with 250-watt solar panels. 250-365-watt panels are most the most commonly installed solar panels for business and residential solar power systems.

If you consider solar panel production ratios (1.31 and 1.61 are the highest and lowest in the U.S.), then divide 11,000kWh (average U.S. residential energy use) by the ratios, then divide that number by 250 (your typical solar panel wattage), you’ll get a an average range of solar panels needed for a house.

Of course this number is going to fluctuate based on the size of your home, your energy use, and how much energy costs in your area.

You can also reduce these costs with tax incentives and the federal ITC tax credit.

You’ll want to know the average kWh energy use in your home start saving energy on your home today.

The average 2,000 sq. ft. U.S. home uses around 1,000 kWh of energy per month or about 32 kWh per day.

And the typical U.S. citizen uses 41% of their electricity on heating a space and 35% on appliances/electronics/lighting.

Of course these numbers will fluctuate based on whether you live in a hot or cold area and how conscientious you are of energy use.

It also depends on how energy-efficient your home is. For example, using ENERGY STAR appliances, having proper insulation, and updated windows can reduce your energy use and, therefore, the cost of your monthly energy bill.

How Long Will It Take To Payoff My Solar Panel System?

To calculate your solar payback time, you’ll want to consider these key numbers:

  • Gross cost: Subtract your up-front incentives/rebates from the gross cost of your solar panel system.
  • Benefits in finances per year: Add your yearly financial benefits together. This includes the amount your saving in energy each year and any other incentives such as tax credits or cuts.
  • Payback Number: Divide the Gross Cost number by your Benefits number. This should be the number of years until you achieve solar payback/payoff.

The solar payback period is the calculated time it will take you to pay off your solar panel system.

The average payback time is around 6 to 9 years.

Every year after that solar payback period is considered all financial gain.

This payback period changes depending on whether you’re part of the PPA (Power Purchase Agreement) program, doing a solar loan/lease, or buying the panels outright.

Really high and volatile energy rates, as well as the fact that solar is becoming so affordable, makes it much easier and beneficial for homeowners to get solar and pay it off quickly.
