Will the array provide power during when it is snowing or hailing?
Full sun is not required for the array to produce, but in poor weather, the panel production won’t be 100%.
On a cloudy day, the modules will produce at a much lower rate.
If snow is accumulates on the modules, production may be zero. Snow tends to slide off modules more
quickly than other roof surfaces, and the modules are usually installed in a south-facing direction. If snow
days are likely, then factor snow days
into the system’s projected production
.
Solar modules can tolerate rough weather. Most are designed to withstand ¾-inch hail at 120 miles per
hour, and they are also built to stand up to direct lightning strikes.
Can I add solar panels to the solar power system later?
Yes. Unlike arrays built with traditional string inverters, adding to the array is a simple procedure without a
lot of design constraints.
