How much electricity do solar panels produce?

The amount of electricity produced by solar panels depends on many factors, such as the number of panels, their efficiency, location and weather conditions. In this article, we will discuss these factors and give an overview of how much electricity solar panels can produce.

Efficiency of solar panels

The efficiency of solar panels means how much of the sun’s radiation is converted into electricity. The efficiency of solar panels on the market today usually varies between 15 and 22 percent. More efficient panels produce more electricity with the same surface area.

Location and weather conditions

Location is one of the most important factors in the amount of electricity produced by solar panels. For example, in Finland, solar panels produce less electricity in the winter months, while the production is significantly higher in the summer. In southern Finland, solar panels produce more electricity than in northern Finland, because the south has more sunlight all year round.

Number of panels and installation

The amount of electricity produced by solar panels also depends on the number of installed panels and their installation angle. In general, the more panels installed, the more electricity is produced. The optimal installation angle and orientation of the panels can also have a significant impact on production.

Examples of production quantities

The following are examples of how much electricity solar panels can produce under different conditions:

• One 300 W solar panel produces on average about 300-400 kWh of electricity per year in southern Finland.
• A 10 kW solar panel system can produce approximately 8,000-10,000 kWh of electricity per year.
• In Northern Finland, production volumes can be around 20-30% lower than in Southern Finland.

Summary

The amount of electricity produced by solar panels varies depending on many factors, such as the efficiency of the panels, location, weather conditions, and the number of panels installed. In general, solar panels can generate a significant amount of electricity, especially during the summer months and in southern latitudes. It is important to design your solar panel system carefully and consider all these factors to achieve maximum returns.
