Total white out is when you can't see 5 feet ahead in heavy or blowing snow. The picture shows just fine snow mist with easily 100 yards of visibility. I've had white out that prevents seeing 15 ft from my front door to the walkway that leads to my driveway.
I have some generic solar panels. 25 watt units. Even with snow they will generate enough to charge a cell phone in mid day sun. Insolation is inadequate in my location to waste money trying to run my house on solar panels. It's marginal even on a clear day.
my pics didn’t load... just blank white images.
Mine put out measurable current even at night (city lights refected back from atmosphere mainly). And if there’s a full moon, probably enough to charge that cell phone.
