How competitive is solar? Competitive enough to build more than 31,000 megawatts, even if no subsidies were available! www.ilsr.org/projects/solarparitymap/. That's what the solar parity map at the link shows. Wow!
Given the current solar tax credits available, the solar parity map finds that customers would be economically rational to build more than 150,000 megawatts of solar. Under current policies, massive amounts of solar would be builit in California, Texas, Florida, and New York.
Visiting the solar parity map is well worth doing!
