How does the yield of solar panels depend on the location?

The yield of solar panels depends on many factors, one of the most significant of which is location. The effect of location on the yield of solar panels can be divided into several different areas, such as geographical location, climatic conditions, seasonal variations and local obstacles. In this article, we will take a closer look at these factors.

Geographical location

Geographical location directly affects the amount of energy produced by solar panels. In general, solar panels produce more energy near the equator, where the sun’s radiation is strongest and the length of the day is more uniform throughout the year. At northern and southern latitudes, the sun’s radiation is weaker and the length of the day varies more with the seasons.

Climate conditions

Climatic conditions, such as cloudiness, temperature and rainfall, also affect the yield of solar panels. Cloudiness reduces the amount of solar radiation, which reduces the yield of the panels. High temperatures can also reduce the efficiency of solar panels, as panels work best in cooler conditions. Rainfall and snow can cover the panels, reducing their yield.

Changes in the seasons

Seasonal changes have an effect especially in northern and southern latitudes. In winter, the days are shorter and the sun’s radiation is weaker, which reduces the yield of solar panels. In summer, the days are longer and the sun’s radiation is stronger, which increases the yield. This variation is more noticeable in Finland, for example, compared to areas close to the equator.

Local barriers

Local obstacles such as buildings, trees and terrain can shade solar panels and reduce their yield. It is important to place the solar panels where they will receive as much direct sunlight as possible without shading.

Summary

The yield of solar panels depends significantly on the location. Geographical location, climatic conditions, seasonal variations and local barriers are all factors that affect the amount of energy produced by solar panels. In order to achieve optimal yield, it is important to consider these factors in the placement and design of solar panels.
