PV Gap

Chad Said:

Solar Power in the future?

We Answered:

Well, we'd have to invent a new technology altogether.

Right now, the most efficient solar cells are barely 20% efficient. Until recently, it took more energy to build a cell than it could produce during its entire life.

So, the question you're asking, while very simple, is actually very complicated from a technical point of view.

To give you an example of the problems we face. Solar cells work better at colder temperature. Yet, the sun is stronger in hotter countries... So, what do we do with that?

The only venue for solar power as we know it is for local production- say for a farm or a small village to ease the load on the main grid.
