In our opinion, you need not bother yourself with the math behind this, especially when you can quickly call us at Select Electrical and Solar Solutions to get a free quote. But if you want to take on a more hands-on approach, follow these simple steps, and you’d do just fine.

  1. Define Your Home’s Energy Usage

Before installing a solar system, you need to know how much energy your home uses in the first place. You can quickly determine your monthly energy consumption by checking your electricity bill for the previous month. You’d find the figure recorded in kilowatt-hours (kWh) at the bottom of the invoice.

  1. Calculate How Much Energy Solar Panels Generate In Your Area

You’ve determined your home’s average energy consumption? Great! Now, you need to determine how much solar energy your geographical location receives.

The intensity of sunlight in a particular area is known as that area’s “peak sun hours”, and the value varies from state to state. You can quickly look up the average number of daily peak sun hours for your state online.

Once you have that daily figure, multiply it by 30 to get the average monthly peak sun hours for your area. The value of your monthly peak sun hours equals the amount of electricity (measured in kWh) your 1kW solar panels will provide in a day!

  1. Determine The Solar System Size You Need To Get

Now that you know how much electricity you can get from 1kW solar panels. You also know how much energy your home needs every month. Knowing the size of the solar system you need to install becomes easy!

To get the size in kW, divide your home’s monthly electricity usage by your area’s monthly peak sun hours, then you’re good to go!

  1. Calculate How Many Solar Panels You Need

You finally have all the information you need to calculate the exact number of solar panels your home needs.

Each solar panel has a power rating in watts. Remember the figure you got after calculating your home’s solar system size?

Now, divide the value of the size of your solar system in watts by the individual wattage of the solar panel you want to install. Voila! The number you get is the exact number of solar panels your solar system needs.
