How much electricity does a solar panel produce?

Every solar panel and every solar power system is unique, just like the homes they power. When trying to figure out how much electricity a solar panel generates, there are several key factors to consider—and some quick math involved too. Let’s break it down step by step.

First off, let’s talk about how to calculate the electricity output of a solar panel. Electricity production is measured in kilowatt-hours (kWh). Most panels on the market today typically produce anywhere from 250 to 400 watts per day. A standard residential solar system usually has a capacity ranging from 1kW to 4kW. For instance, a 4kW solar system installed on an average-sized home could generate up to around 3,000 kWh annually—factoring in the hours of sunlight throughout the year. However, it's important to remember that other variables, like the size of the panels, their positioning, and the local climate, can all influence performance.

In addition to the amount of sunlight available, external factors such as weather conditions, panel efficiency, and the angle at which they're mounted can affect how much electricity your solar PV system produces on any given day.

 

How Much Electricity Will My Solar Panels Produce?

Since no two solar panels are exactly alike, calculating their potential output requires a formula. Using this method gives you a rough idea of how much electricity your solar panels can generate each day.

To calculate the daily electricity output:

• Start by multiplying the square meterage of one panel by 1,000.
• Next, multiply that result by the efficiency rating of your panels (converted to a decimal).
• Then, multiply that figure by the average number of daily sunlight hours in your area.
• Finally, divide the total by 1,000.

For a monthly estimate, simply repeat the process and multiply the daily output by 30.

Let’s illustrate this with an example. Suppose you have 1.5m² panels with an efficiency rate of 80%, and your location enjoys six hours of sunlight per day:

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

How Much Solar Power Do I Need?

Once you know how much electricity your panels can produce, you can work backward to determine the appropriate size for your solar system based on your household's energy consumption. It's crucial to ensure that your system meets your needs without being oversized or undersized. Don't worry—you don’t have to tackle this alone!
