When it comes to solar power, every panel and system has its own unique characteristics. That’s why figuring out how much electricity a solar panel can generate requires some careful consideration of several key factors—along with a bit of straightforward math. First things first: how exactly do we calculate the electricity output of a solar panel?

Electricity output is typically measured in kilowatt-hours (kWh). Most modern solar panels produce anywhere from 250 to 400 watts per day. A typical home solar system usually ranges between 1kWh and 4kWh in capacity. For instance, a 4kW solar power system installed on an average-sized house can generate up to approximately 3,000 kWh annually, even accounting for variations in sunlight hours. However, the actual output depends on various factors, including the amount of sunlight your area receives throughout the year, the size and positioning of the panels, and the weather conditions that may temporarily affect performance.

Since each solar panel differs, we’ll walk through a simple formula to help you estimate how much electricity your solar panels can produce. By following these steps, you’ll get a rough idea of the daily electricity generation potential for your solar panels:

• Multiply the square meter size of one panel by 1,000.
• Take the result from the first step and multiply it by the efficiency rating of your panels (expressed as a decimal).
• Next, multiply that number by the average daily sunlight hours in your region.
• Finally, divide the total by 1,000.

To calculate the monthly estimate, just repeat the process and multiply the daily output by 30. Let’s look at an example calculation using 1.5 square meters of panels with 80% efficiency and six hours of daily sunlight:

1.5 × 1,000 = 1,500
1,500 × 0.8 = 1,200
1,200 × 6 = 7,200
7,200 ÷ 1,000 = 7.2 kWh per day
Monthly total: 7.2 × 30 = 216 kWh
