Solar panels have compounds that are semiconductors, the physics that governs these components do not “like” extremes in temperature.
And the solar energy has to get to the semi-conductors. Who is going to clean off the snow?
The Institute for Energy research (IER) reports:
“Record cold temperatures have hit parts of Europe and Asia causing electricity prices to spike as the normal generating supplies of electricity could not keep prices in check. Spain registered its coldest temperature on record, at -35.6 degrees Celsius, and several areas of the country, including Madrid, are under 18 inches or more of snow and may get record-breaking snowfalls. The electricity price in Spain soared to nearly €95 ($116) per megawatt hour—up 123 percent from prices the previous week and nearly three times higher than the 2020 average.”
