Most American houses require between 16 and 20 solar panels to meet their energy bills. However, this figure is solely based on the typical American household’s power usage. 

Depending on how much energy your household needs, the power rating of each solar panel you install, and how effectively the panels can operate in your region, you can determine the ideal quantity of solar panels for your home. 

This step-by-step procedure lets you figure out how many solar panels you need to power your house. 

Step 1: Assess your consumption of electricity 

To find out how much electricity your home typically uses each month, first check over your power bills. Power consumption varies with the seasons, so to obtain an overall average, review your monthly invoices for a year, add the total number of kilowatt-hours you consumed each month, and divide the result by 12. 

Find out how many peaks solar hours your location receives in step two. 

Finding out how many peaks and sun hours your location experiences each day is the next stage since the actual output of a solar panel is influenced by how much direct sunlight it receives each day.

Step 3: Calculate the wattage of the solar panel 

Next, to find out how much power any solar panels you could buy can produce, examine their wattage. Since not all panels have the exact quantities of energy, their wattage indicates their production. The more panels you need to power your home, the lower their power rating will be. 

When discussing the total energy production of a solar panel system, you add up the wattage of all of its panels, which requires using numbers in the thousands of watts. The data may be made more straightforward by measuring the output in kW rather than watts. Since one kilowatt equals 1,000 watts, 16 solar panels with 300-watt ratings each have a combined rating of 4.8 kW. 

Under ideal circumstances, a 4.8 kW solar power system can generate 4.8 kWh of electricity in a single hour. The system won’t create as much energy in the actual world.
