To light Las Vegas, you would have to cover the whole state of Nevada with solar panels. Everything would be cut off from sunlight, no grass, no crops, cows sitting in shade. Building roofing shingles out of solar cells is quite another thing. They need to be replaceable and tough enough to stand hail and tree limbs falling. Making all roofing out of solar would cut the demand way down and could be a long term solution for rising demand.

As for myself, I could replace all my usage except for my air conditioners. I would keep them on the grid. I have a large roof area and seperate garage area.

Cover the whole state of Nevada to power Las Vegas ? Not quite.

You get basically 10 watts per square foot from a PV, and you can count on 5 hours per day as an average in Nevada. So 5wh per square foot, or 140Mwh per square mile per day. That’s enough for 5,000 homes. If you covered a square 100 miles on a side, you’d have power for 50 million homes. 200 miles on a side and you’d have enough power for all the homes in America. 300 miles on a side and you’d have enough electric power for all homes and businesses in America. And have plenty of Nevada dessert left over.

Cost is the issue — finding space for enough solar panels is not.
