Modern consumer solar is breathtakingly amazing.
We forget how bad things were just 15-20 years ago.
Earlier today, I set up a folding panel with sunpower cells; it was literally vertical, in a window, facing South. Total surface area.. maybe 3sqft, weighing 1lb. It was making ~20W for 4 hours, and managed to completely recharge my 130Wh battery pack in 8. Through a window. In the winter, in Canada.
The thing cost $120.
It's easy to get lost in the constant claims of breakthroughs while forgetting what an amazing time we live in. 20 years ago, this panel would have blocked out the sun and cost a months' salary.
