A recent report by GTM Research & SEIA shows that the US solar PV market is becoming increasingly fragmented. In 2005, California represented 80% of the U.S. solar market; today, it's only 30%. In 2010, East Coast markets lead by New Jersey, Pennsylvania, Florida and North Carolina, installed more solar than California. And the trend continues in 2011.
Whilst such diversity is a positive thing for the overall health of the US solar market, ensuring sustainable growth in the long term and dealing with different incentives and regulations across the states can prove a headache for the solar industry. In many instances, the REC dominated markets of the East bare little resemblance to the established markets in Western states and with strong growth being observed in the east of the country, many solar developers are shifting an increasing proportion of their operations to the market.
