Solar Efficiency Chart



The above chart illustrates the efficiency of a solar energy systems over time.
As one can see, multijunction concentrators is currently (!) the tech to beat, boasting a 40.7 efficiency rate.

What this chart says to us is that solar power is still in its infancy, just beginning to chart in terms of exponential growth.

And that is a very exciting thing!

Imagine solar cells with 100 percent efficiency. This chart says to us that that goal is just around the corner.

Sweet.

This lovely chart is the work of the National Renewable Energy Laboratory.
