Very good.

We have laboratory prototypes right now reaching 29%.

Essentially, they're coming up with better methods to trap the sunlight and to turn it into energy.

The cost, let's talk about cost now.

So back in 2004, the cost for solar panels was approximately $5 to $7 per watt.

I know it's a little hard for most of us to understand watts and how many watts of each panel or whatever, but let's just use watts and that dollar figure to compare panels back then to today.

So $5 to $7 per watt back then.

And today we are at, anybody?

$0.50 is the figure that I found.

You said $0.20?

All right, that's really good, actually.

I hope you're right and my figure is wrong here.

For what?

So that's over a 90% reduction in the cost to collect solar energy.

Yeah, without a doubt.

Durability and lifespan.

2004, the expected lifespan of solar panels was around 20 to 25 years.

There is definitely performance degrading happening, approximately 1% degradation per year.
