Last I heard silicon based was getting close to 25% efficiency. So for the same amount of energy of a square meter of a traditional panel, you'd need 10 square meters. That's a huge solar panel for only a regular amount of energy. I assume they'll continue to get more efficient though, maybe in a few years it'll be worth it.
