How to calculate the solar system size I need?

To calculate the size of solar system that will be perfect for your home, follow these steps:

  • Figure out your current monthly and daily energy usage. You can do this by looking at your previous (preferably 12 months) power bills. Divide your average monthly bill by 30 to get the daily kWh and divide the annual bill by 12 for the monthly kWh.
  • Research and find out the amount of sunshine hours your area receives. Use a sun hours chart and record the peak sun hours for the city closest to you.
  • Measure your roof’s total size to figure out how many watts per square meters will be required. This will determine the number and size of panels you’ll need.
  • Finally, divide your daily kWh consumption by the peak sun hours in your area. Multiply the result by an efficiency factor of 1.15, which gives you the size of the solar system you need. You can also use an online solar system calculator to do the math.

How much will I save with solar panels?

It depends on how much energy you consume and the rate of electricity in your area. Homes that receive large power bills at the end of the month stand to save more than those with small bills.

You’ll also save more with solar panels if you live in an area where the cost of electricity is relatively high. Any small increase in the prices of electricity means more savings for solar owners.

Will I eliminate my bills with solar?

Not 100%. Even though you save a lot on power bills with solar, you only cut about 80 – 90% of your bills. At the end of the month, you’ll still receive a bill since you still rely on grid power in the evenings.

The only way you can achieve net-zero power savings is to invest in a solar battery.
