Solar panels work best at temperatures of 77 degrees Fahrenheit (25 degrees Celsius), but will lose efficiency faster as temperatures rise above this. However, if you live in an area with heavy snowfall, you may want to consider investing in snow guards or a snow rake to prevent snow from accumulating on your panels and blocking the sunlight.
For example, the optimal tilt angle of a solar panel in the Northern Hemisphere is equal to the latitude plus 15° in winter and minus 15° in summer. On the other hand, in the Southern Hemisphere, the latitude is minus 15° in winter and plus 15° in summer. The calculation goes as follows:

Achieving 1.5 degree C-aligned targets for zero-carbon power, however, will require such gains to accelerate dramatically — the global share of solar and wind in electricity generation has been growing by an annual average of 14%, but this needs to reach 24% by 2030.
For example, when the temperature coefficient is minus 0.5 percent, it means that efficiency decreases by 0.5 percent for every degree above 25 °C (or every 1.8 degrees above 77 °F). Solar panels from different manufacturers will vary in their temperature coefficients.

At the top of the atmosphere, the difference of the incoming solar radiation energy minus the amount of solar radiation energy that is scattered back to space (this difference being the amount of solar radiation energy absorbed by the Earth system) must balance the emitted infrared radiation energy for radiative equilibrium to hold.
Hailstorms can cause severe damage to solar PV plants. In Texas, 400,000 of a solar plant''s 685,000 modules were damaged in a hailstorm in 2019, causing at least US$70 million in damages.
Solar panels angled at 45 degrees will allow hail to slide off as it hits, providing them some protection and still letting them generate energy. Yet, hailstorms can severely damage even slightly angled solar panels.

We have the 82,800 Btu/hr. snowmelt load, and then we need to recalculate the heating load at a 20-degree-F outdoor temperature instead of minus 5 degrees F. If we do that math and come up with, say, 56,566 Btu/hr., then the boiler needs to be able to supply 139,366 Btu/hr. - enough to handle both the snowmelt and heating loads.
