“The smartest energy choice under the sun”. Perhaps in these harsh times where we’re running out of fossil fuels for our use and have started using solar energy, do you really think that they can only be used in the presence of the sun’s direct rays?
Did you know that solar panels can be used even in extremely low temperatures and even in cold deserts for that matter? You might be fascinated to know that solar panels absorb energy from our sun’s readily available abundant light and not its heat!
Solar energy is way more cheaper than fossil fuels and its costs have fallen more than 99 percent since 1977. It is one of the fastest energy sources to deploy.
How do they work in snow and during rains?
One of the most intriguing things which one wouldn’t know about or has a haphazard perception about is that solar panels can actually work even when there is snow and when it showers thoroughly. It is quite interesting to know that even during these compromised climatic conditions they have the potential to generate electricity even with a layer of snow on top of the panel. In fact, this may even increase its efficiency as sunlight is still received in some form. The so-called dark reflective glass on the front side of the panel initiates snowmelt and makes it slide off before it clogs the working performance of the panel. This is because of the reason that dark
colored panels attract heat and helps in the melting process easily. As one must have already observed that the panels we have seen or come across are usually tilted towards the sky. Ever wondered why? This 30 to 45-degree tilt is made so that all the unwanted snow cannot pile up on top of the panel directly affecting its operating efficiency. This states that investment in solar panels in these cold weather places is certainly a good investment opportunity for prospective buyers.
During the rainy days, the sun, perhaps, is still delivering its daylight to solar panels during a rainstorm facilitates electricity generation in the form of radiations. In fact, surprisingly, rainwater helps to wash off any form of dirt or dust particle present on the panel’s glass surface and makes it gleam beautifully. This is because snow tends to have a form of anti-soiling properties which even takes of dirt while melting. However, there is one drawback as the electricity generated in this case depends on the density of the clouds which proportionally strikes its efficiency.
Science behind their working in cold climatic conditions
Even in extremely glacial regions, solar energy can be utilized for electric power generation. For that matter, it increases the optimal efficiency of the panel. So, its working goes this way; firstly, the electrons in the silicon are put in motion, when the photon particles of the sunlight collide with the photovoltaic cells. Furthermore, this leads to the creation of an electric current and is sent to the electric distribution box. A rechargeable solar battery can somehow help store this electricity generated when in times of need. Primarily, during some sort of high electricity usage, during the odd hours, which is basically, during the nighttime or even when unexpectedly the grid stops working.
Electrons usually do not have any movement in cooler regions. But when these are activated by increasing sunlight, a significant distinction is observed in the voltage of the electricity generation as more energy than usual is generated. This is the main reason why solar panels have more efficiency when in colder areas. Any undesirable output in these regions will be predominantly because of the shorter sunlight hours or heavy frosty weather.
One of the most important things to be kept in mind while removing the snow from the panel is that never use it. It has the potential to destroy the panel using any tool, so it’s indeed better if not put into use. Additionally, it may even hamper the warranty of the panel by decreasing its lifespan which is more than 25 years! In these cases, the optimal solution to prevent this destruction is to purchase snow guards. They can help in providing for any form of injury to the panel and happen to be relatively cheap and facilitates the speedup of snowfall off.
Also, the cold climatic conditions help to prevent solar panes from heating up and catching fire. Sometimes, in hotter regions, there tends to be so much heat that it eventually ends up with unwanted overheating of the panel. Hence, colder areas can in some way be the ideal condition for the panels to perform effectively and efficiently.
