Is Sweden an idyll for solar panels?
Sweden + Solar Panels = True...?
A common misconception is that we have too few sun hours in order for solar panels to pay off - well, that is not the case! In this artice we will sort out some of the most common misconceptions, so stay tuned!
The cold Swedish winter ought to slow down the generation of electricity, right?
Of course it's true that we have a cooler climate than most parts of the world, but that doesn't mean that your electricty production has to suffer, on the contrary! In fact, heat has a negative effect on the solar panels.
You can expect a deterioration of approximately 0.4 % for every degree that rises above 25 degrees Celsius. Therefore, if the panels are for example 30 degrees, it means that the production of electricity reduces by; 0.4 % × 5 degress = 2% deterioration. Let's say that it's 30 degrees in the air and the burning sun is shining on the solar panels at the same time, it's possible that the panels can rise up to 55-60 degrees celcius. If that happens there will be a power deterioration of as much as 12-16 %.
Sweden has multiple seasons. And because of that, the amount of sunlight varies every season. Swedish summer is relatively cool and has more hours of sun. So in fact that solar panels actually perform better in a cooler climate, meaning that we have excellent conditions for producing plenty of solar energy in Sweden despite fewer hours of daylight during the winter months. The excess solar energy you produce and sell back to the electric grid during the summer months compensates for the loss of solar energy during the winter season.
OK, but aside from the temperature, do the solar panels really withstand the pressure of snow and rain?
Our solar panels are manufactured to handle all different nordic climates. The solar panels we use are of the highest quality and rigorously tested before leaving the factory. The solar panels can handle incredibly high pressures and as the snow settles as a blanket on the panels, the weight is evenly distributed and has a minimal impact on the solar panels. When it comes to rain, the panels themselves are not affected. However! Rain comes with the clouds, which instead reduces the production of energy a bit. The rain helps you to clean the panels, and that's good!
