Solar has seen a 70% compound annual growth since 2010, with over 4GW installed in 2013. Indeed, preliminary numbers indicate that approximately 28% of all new US generation capacity installed in 2013 was from solar. Despite this growth, solar generation is still a small part of the overall generation mix. This holds true even for the states with the highest solar penetration.

A new study from Lawrence Berkeley National Laboratory finds that homes in California with rooftop solar installations sell for higher prices than comparable homes without solar. The authors find that the value of homes increases by $5,900 for every kW of solar installed, though this premium decreases by 9% per year of system age.
The National Renewable Energy Laboratory (NREL) recently released a report that breaks down the ‘soft costs’ associated with the installation of residential and commercial photovoltaic systems in greater detail than ever before, with detailed looks at customer acquisition and system design costs, as well as permitting, inspection and interconnection costs.
A new study from the Rocky Mountain Institute and the Georgia Tech Research Institute finds that U.S PV installation labor costs can be decreased from $0.49/watt to $0.29/watt by utilizing installation best practices. Researchers studied installation practices at 26 sites in the U.S. and Germany to determine current practices and future opportunities.
With distributed solar growing at a record pace, states nationwide are assessing the benefits and costs of this dynamic resource. The implications of these studies couldn't be higher, as cornerstone policies such as net metering are on the line.
In its review of 15 distributed solar PV benefit and cost studies, the Rocky Mountain Institute (RMI) finds significant variability in estimated distributed PV values, owing to differences in methodology, local context, and input assumptions. RM
This report provides a new cost-benefit analysis of the impacts of solar distributed generation (DG) on ratepayers in the service territory of Arizona Public Service (APS). The study shows that distributed solar generation (DG) and net energy metering will provide Arizona Public Service (APS) customers with $34 million in benefits each year.
A recent NREL report finds that in 2011, 17% of U.S supermarkets were in utility territories where PV could be installed at or below the cost of traditional generation. In 2012, they estimate that this percentage increased to 40%. The report is
Today, from security and battlefield readiness to cost savings and efficiency, America’s military is making an unprecedented commitment to renewable energy sources, and solar is “walking point” on many of these new, innovative efforts.
As of early 2013, there are more than 130 megawatts (MW) of solar photovoltaic (PV) energy systems powering Navy, Army and Air Force bases in at least 31 states and the District of Columbia. See what states have the most solar installed on our interactive map.
