How much electricity does a solar panel produce?

When it comes to solar panels and solar power systems, each one is unique. Figuring out how much electricity a solar panel can generate involves considering several key factors and doing some simple math. First off, let’s break down how to calculate the electricity output of a solar panel.

The output of a solar panel is typically measured in kilowatt-hours (kWh). Most panels on the market today are designed to produce anywhere from 250 to 400 watts per day. A standard household solar system usually has a capacity ranging from 1kWh to 4kWh. For instance, a 4kW solar power system installed on an average-sized home can generate approximately 3,000 kWh of electricity annually, factoring in the available sunlight throughout the year.

Several variables influence the performance of a solar photovoltaic (PV) system, including panel size, positioning, orientation, and local weather conditions. These elements can temporarily affect the overall output of the system.

How Much Electricity Will My Solar Panels Produce?

Since every solar panel varies, it's essential to use a formula to estimate their electricity production. The following steps provide a rough estimate of the daily electricity generation for your solar panels:

• Multiply the square meter size of one panel by 1,000.
• Then, multiply that result by the efficiency rating of your panels (expressed as a decimal).
• Next, multiply that number by the average daily sunlight hours in your area.
• Finally, divide the result by 1,000 to get the daily output in kWh.

To calculate the monthly output, simply multiply the daily result by 30. Here’s an example using a 1.5 m² panel with 80% efficiency and six hours of sunlight daily:

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

This equates to approximately 216 kWh per month.
