How is the energy footprint of this process compared to the standard way to produce silicon directly? Without answering this question we are still in the dark about the benefits of the new process.

If you buy panels for a certain cost, and you say they cost X per kWh, you also have to say how long a period of time it takes to get to that number.

No subsidies included.

Germany is installing for $2/watt.

—

Right now the cost of silicon cells is running about 35 cents per watt. Dropping the price of silicon will help, but that’s not where the expense is with solar. US solar is averaging around $3.50 watt while panels are averaging about 63 cents.

You may of course have meant that. the key is that 8 cents would eliminate the need for susidies and make solar competetive with utility provided power anywhere in the southwest.

In this price range non-silicon material prices would start limiting further cost reductions.
