Soon, I hope. But no need to wait. You can expect to get 20% efficiency from solar panels today! (Meaning engineers have not figured out how to convert 80% of the available solar energy into electricity...yet.) But what you get now is good, clean energy, and 100% renewable! And, after the panel pays for itself, the rest is totally FREE!

Now the power is in your hands!
