Solar photovoltaic (PV) panels generate the most energy per square meter when they receive direct sunlight.
But what happens when it is overcast and rainy?
When clouds block out the sun, your solar panels will still produce clean electricity. This is true even in the wintertime (in fact, all things being equal, modern PV panels actually perform better in colder temperatures).
But how can solar panels possibly generate power under cloud cover?
Why Solar Power Works on Overcast Days
Solar panels harness both visible light and infrared light in order to create usable electricity:
Even if solar panels only used ultraviolet light, they would still be able to generate electricity during cloudy days. If you have ever gotten sunburned on an overcast afternoon, you understand this concept intuitively.
But all of the above is theoretical. Let us look at some actual proof that solar works just fine in cloudier, rainier climates.
Real-world Proof That Solar Works When It is Rainy or Cloudy
You would think that countries along the equator would lead the global solar revolution. But in fact, many of the most active solar hotspots are in colder, rainy regions that do not receive year-round sunshine:
A little closer to home are New Jersey, Massachusetts, New York and Connecticut northern states that receive their fair share of storms and cold temperatures. Customers in these areas would not invest in solar power if the numbers did not make sense. And yet, these are some of the most active markets that Direct Energy Solar currently serves.
