## How much solar power will you need?

To determine your home’s average energy requirements look at past utility bills.

You can calculate how many solar panels you need by multiplying your household’s hourly energy requirement by the peak sunlight hours for your area and dividing that by a panel’s wattage.

Use a low-wattage (150W) and high-wattage (370W) example to establish a range (ex: 17-42 panels to generate 11,000 kWh/year).

Note that how much sunlight your roof gets and factors such as roof size and battery storage will figure in as well.

If you work with SunPower, our solar experts will handle all these calculations for you.

But to give you some idea of how many solar panels are needed for the average home (or for your home in particular), here is a sample set of questions that a solar professional might use to figure it out:

How many watts do you currently use?

Look at your electricity bill for average usage.

Look for “Kilowatt Hours (or kWh) Used” or something similar, and then note the time period represented (usually 30 days).

If your bill doesn’t show kilowatt hours used, look for beginning and ending meter readings and subtract the previous reading from the most recent one.

You want daily and hourly usage for our calculations, though, so if your bill doesn’t show a daily average, just divide the monthly or annual average by 30 or 365 days, respectively, and then divide again by 24 to determine your hourly average electricity usage.

(And just in case you are wondering, a kilowatt-hour is how much power you are using at any given time multiplied by the total time the power is being used.)

A small home in a temperate climate might use something like 200 kwh per month, and a larger home in the south where air conditioners account for the largest portion of home energy usage might use 2,000 kWh or more.

The average U.S. home uses about 900 kWh per month. So that’s 30 kWh per day or 1.25 kWh per hour.

That’s the number of kilowatt-hours you need your solar system to produce if you want to cover 100 percent of your energy needs.

It’s important to note that solar panels don’t operate at maximum efficiency at all times. (See Solar 101: How Does Solar Energy Work?).

Weather conditions, for example, can temporarily reduce your system’s efficiency.

Therefore, experts recommend adding a 25 percent “cushion” to your target daily average to ensure you can generate all the clean energy you need.
