The folks over at Solar Power Rocks have gone through the solar policies of all 50 US states in order to rank them all. Solar Power Rocks’ overall grades for each state are based 60% on solar incentives (overal solar system payback time based on all incentives, feed-in tariffs, tax credits, utility and state rebates, etc.), 20% on utility policies (whether or not the state has a renewable portfolio standard / renewable energy standard, the strength of that RPS/RES, and electricity rates), 10% on interconnection policies, and 10% on net metering policies.
For a quick glance at the results, here’s a colorful infographic from Solar Power Rocks (note the color legend on the top-right corner of this article):
For another look at the ranking criteria, here’s a pie chart:
And for a detailed breakdown of how the states performed on each criteria, here’s a colorful spreadsheet (click to enlarge — still hard to read):
Interestingly, I’m on the verge of reporting per capita solar power capacity state rankings. They won’t match up perfectly with these solar policy rankings, but I bet there will be some overlap. Stay tuned to CleanTechnica for those exclusive rankings.
