The warm season is almost here, but we will have to deal with fog and overcast skies for a few more months. During the winter the sun, especially in the regions of Northern Italy, is desired. Not only from us, but also from our Solar Panel Lahore Contrary to what one might think, however, the modules on the roof of the house also produce when the weather is bad. But how much do they make? Let’s clarify the functioning of the systems during the winter months.
Does the photovoltaic system also work in winter?
Of course yes! The photovoltaic modules are not damaged by the cold. In reality they work optimally with temperatures below 25° C. That’s why their performance is not affected by low temperatures and they continue to produce clean energy even in winter . Obviously as long as the sun keeps shining!
We know that during the winter the hours of light are reduced and with them also the time needed for energy production. The trick is to methodically design the installation of the modules . By paying attention to the shadows and choosing the pitch of the roof facing south, the photovoltaic system will continue to produce energy throughout the winter, even if to a lesser extent than in the summer months.
Fog and cloudy sky: is the photovoltaic system working?
Foggy or cloudy days put a strain on the efficiency of the photovoltaic system. But production does not stop . The panels also work with diffused light, with an income much lower than the normal one. In situations of this type, CIS modules and latest generation photovoltaic cells are indicated, which offer excellent yields even on days without sun.
Are rain and snow a risk for photovoltaic modules?
Absolutely no! The rain does not damage the panels in any way. Indeed, we can say that a rain of a certain intensity can be useful for removing dirt and dust that have accumulated during the summer and spring months, limiting the efficiency of the panels. That’s why covering the plant in winter (as many believe right) is actually a mistake.
Even snow does not cause damage to the modules. However, many prefer to remove it because, by covering the surface of the panels, it limits their production.
How much does a photovoltaic system make in winter?
We understood that gray days, fog and little light affect the yield of the plant. The truth is that when we decide to install Solar energy in Pakistan on the roof, we don’t have to consider their monthly production, but the overall yield over the year . This also applies to those who already own an implant. If we were to rely only on the data collected in the coldest 2-3 months, we would conclude that photovoltaics are not worth it. In reality, despite the drop in production during the winter, having a plant is definitely worth it! In fact, with the warm season, the energy produced will amply cover our needs, so much so that we forget the slight losses of the winter period.
Furthermore, this decrease varies from region to region and is felt more by those who live in Northern Italy. To overcome this problem, however, we can choose to install CIS modules, which are more efficient even with bad weather and diffused light than normal crystalline silicon panels.
