The sky is overcast. Harsh winters. Rain. “Should I even bother” may be a question you’re asking yourself if you live in a place like this. The conventional belief is that the output of your system is directly related to the weather. Instead of benefiting from solar energy the same way that cities such as Los Angeles and Florida will, cities such as Pittsburgh and New York will not. Contrary to popular belief,
In locations with terrible weather as well as in areas where the sun shines, solar technology has made significant strides. We’ll go over a few of them with you now.
Solar performs well in overcast conditions.
It’s ironic that Germany, the world’s solar superpower, is also one of Europe’s cloudiest nations. During the month of May, it generated more than 95% of its electricity demands from solar power. The amount of sunlight that Germany receives is nearly equal to that of Alaska, yet the country still manages to generate around 25 gigawatts of electricity using solar power. Isn’t it incredible? When it comes to how much sunlight you get each year, cloudy days aren’t as important. Cities with overcast weather, like Cleveland, Portland, and Boston, are excellent candidates for solar power!
winter and solar panel performance
Solar energy relies on light, not heat, as a critical consideration. Regardless of how chilly it is outside, your solar panels will be in fine working order as long as you get some sunlight. As a rule of thumb, you should aim to maximize the amount of sunshine that reaches your solar panels.
the resulting impact on the power generation
During overcast weather, how much power will your solar panels generate? On a sunny day, your solar panels will only provide 25%-45% of the electricity they generate. Even in low-light settings, solar panel manufacturers such as SunPower and LG have developed panels that maintain their efficiency and production levels.
So, what’s the conclusion? Is solar still effective when it’s raining or overcast? The answer is yes, even in cities like Ohio (a small 4kW solar energy system can cover the majority of the electricity bills). It doesn’t matter if the weather is cloudy or if it’s raining. However, remember that your roof is solar-ready and receives no shading!
