I have a 15.83 kW (44 panels) array in sunny 🌞 California! 
Discussion
I live in Alberta. Snowbound for six months out of the year. Little sunlight during those months. Solar energy is not an option. It's been done, but its an expensive endeavor that doesn't always work out.
This tech is around 15 years old. I had big hopes for it.
3 questions;
Average cost per panel?
How many acres needed?
Did you set them up yourself?
