Hello, solar enthusiasts! If you’re a regular reader, you might have noticed something a bit unusual happening in the world of weather patterns. As you know, these meteorological shifts can significantly affect solar panels for your home and larger solar assets managed by solar companies. And with a potential shift to La Niña conditions in North America, it’s essential to understand what this could mean for the solar industry and your personal solar array at home.
La Niña is a weather phenomenon, characterized by cooler sea surface temperatures in the equatorial Pacific, that significantly impacts the Atlantic hurricane season. This shift impacts the jet stream and therefore the amount of vertical wind shear, which controls hurricane formation. Wind shear disrupts hurricanes, but with less wind shear during La Niña, we could see more intense and numerous hurricanes. This change is particularly true for the Gulf of Mexico, which historically sees up to 10% below-average solar irradiance due to increased storm activity during La Niña years.
The Atlantic coast, though, often experiences the opposite effect. Here, we observe up to 5-10% above-average irradiance during summer months when La Niña is in effect. Despite more hurricanes occurring, the periods of relative stability between these large storms result in clear skies. These calm periods outweigh the storms and lead to higher average overall solar irradiance for the Atlantic Coast.
Now, this might sound too technical for some, but understanding these weather patterns is essential for both homeowners with solar panels and solar companies. The implications of these patterns extend to the distribution of solar generation across the US. A typical La Niña summer could mean a 2.7% increase in rooftop solar generation for New York, and 2.1% for New England. However, in contrast, places like Texas, which has many utility-scale solar assets, could see a decrease in production by about 1.6%.
The bottom line is that while weather patterns might be out of our control, that doesn’t mean we can’t prepare or adjust for them. If you’re a homeowner with solar, or if you’re exploring options for a solar array for home use, be mindful of these potential changes. If you work with a solar company, make sure you stay updated with the latest weather predictions to optimize your assets. After all, the more knowledge we have, the better we can navigate the dynamic world of solar power. Remember, the sun may not always come out tomorrow, but with solar, you’ll be ready when it does.

Always consult with a trusted solar company or expert when making decisions about your solar setup.
