34. Should have added...
So if we use the median numbers of $66,000 to install and a life expectency of 15 years, you get 165,600 kWh produced for $66,000, or approximately $0.40 per kWh.

Rates vary across the country, but I currently pay $0.138 per kWh.

So, putting aside environmental arguments, from a purely ecomnomical standpoint solar is still too expensive. And the cost of panels is only 50% of installation cost, so improvements in efficiency only reduce the cost by half of the efficiency increase.
