811MW of solar installed in the US in the 4th quarter of 2011. That is almost the equivalent of a nuclear reactor. While today's grid tied solar only has a 25% capacity factor; meaning it is producing peak electricity only 6hrs a day, this is a significant amount of power. 1MW powers approximately 200 US homes.
In the 4th quarter of 2011 South Carolina approved installs for approximately 130kw that's 1/1000th of the overall US market. California is still the US leader with 38% of the US market. NJ is 11% of the overall market leaving the 47 remaining mainland states to divide up 51%. Assuming the top 5 of those take 8% each that leaves 11% for the remaining 42 states. That is a 1/4% for each state. That gives SC a target of 2MW a quarter and 8MW a year goal to be considered even thinking of contributing to a domestic energy policy. That's a steep curve but one we could easily achieve if we worked together.
In Q3’11, the US PV market grew by 32% from Q2’11 and could reach 1.9 GW for the year, which would mean that the market has doubled in size for the second consecutive year. For large-scale non-residential and utility-scale projects in Q3’11 and Q4’11, the scheduled expiration of the US federal cash grant has encouraged progress to meet qualifying requirements; ongoing installation will continue throughout 2012, stimulated by the progress requirements for these cash grants.
