About Why are photovoltaic panels frosted
Solar panels can often still work when frost gets on them, although there could be a slight decrease in their efficiency. The main concern with frost is that it can block the light from reaching the solar cell, which reduces its ability to generate electricity. In this article, we’ll discuss why frost can reduce the efficiency of solar panels .

Because heat can actually cause the photovoltaic cells that make up the panels to perform suboptimally, colder temperatures (especially colder temperatures without snowfall) are ideal for solar.
University of Illinois scientists have developed a way to remove snow and ice from solar panels at a much faster rate than conventional approaches. It is based on a glass coating on a film with high optical transparency and superhydrophobicity.
Snow and ice will under various circumstances cause both uniform and partial shading. It is necessary to examine the behaviour and influence of snow and ice on photovoltaic panels, to accurately determine and improve the long-term performance of solar power in snow-prone areas.
My untested hypothesis is that it's a "dead" panel. The others all carry current and are warmed a little bit. Maybe just a tiny bit of current so early in the morning, but some current nonetheless. The frosted one carries no current and remains frosted until warmed by direct sun.

6 FAQs about [Why are photovoltaic panels frosted ]
Do snow and ice affect photovoltaic panels?
Snow and ice will under various circumstances cause both uniform and partial shading. It is necessary to examine the behaviour and influence of snow and ice on photovoltaic panels, to accurately determine and improve the long-term performance of solar power in snow-prone areas.
Why do solar panels melt snow?
Solar panels are designed to attract the sun’s rays and trap them. Generally speaking, solar panels are 2°C (36°F) warmer than the ambient temperature. So even a glimmer of sunlight can cause the solar panels to start warming up, and in turn, melt the snow that is on them. Snow can act as a way to clean your solar panels (for free)!
Why do solar panels produce more electricity in the winter?
That’s why solar cells produce electricity more efficiently when it’s colder. 3 In the winter, it’s also less likely for solar panels to reach their peak temperature, or peak power. 4 Once their temperature rises above that peak temperature, solar panel performance decreases.
What happens if solar panels are covered in snow?
If snow covers your panels, they can't produce power – but it's easy to clean them off with the right equipment. Solar panels need sunlight to produce power, so if your solar panels are covered in snow, they will not generate electricity. Most panels are tilted at an angle, so snow will slide off on its own accord, but that can take time.
Do solar panels work better in the Cold?
In fact, photovoltaic (PV) solar panels work more efficiently in the cold. When panels are overheated, they can’t perform as well. Manufacturers rate their solar panels for how well they perform based on their peak temperature, the temperature beyond which the efficiency of the solar panels starts decreasing.
How do solar panels keep snow from accumulating?
Installation racks are also typically tilted up at 30 to 45 degrees, which keeps snow from accumulating (to a point). 10 A light dusting of snow is likely to blow off or disappear rapidly. In fact, on cold, clear days, snow from the ground can reflect extra sunlight onto your solar panels like a mirror.
