The U.S. solar energy industry grew to new heights in 2008 and many industry observers expect thatgrowth to continue in 2009. Total capacity grew by 1,265 megawatts (MW)1 in 2008, up from 1,159 MW installed in 2007.2 This brings the total installed capacity up by 16 percent to 9,183 MW. Capacity in both photovoltaic (PV) and solar water heating systems grew at record levels. And while no new concentrating solar power (CSP) plants were completed in 2008, projects totaling more than 6,000 MW are in the pipeline most with signed purchase power agreements. Solar pool heating capacity grew at a slower rate than in 2007, reflecting conditions in the residential real estate market.

In 2007, the U.S. solar energy industry saw a glimpse of a gigawatt future. There was signi?cant growth in the commercial and residential PV markets and a new utility-scale segment for PV emerged with the fastest growth of all segments representing over 15 percent of the annual U.S. installed PV capacity. The ?rst concentrating solar power plant was built in more than 15 years with dozens more utility-scale projects in the pipeline. The expansion of the solar water heating market continued. Thousands of U.S. jobs were created and billions of dollars were invested. And, the industry strengthened its presence in Washington and our united coalition support across the country.
The National Renewable Energy Laboratory (NREL) routinely estimates the technical potential of specific renewable electricity generation technologies.
Establishing interconnection to the grid is a recognized barrier to the deployment of distributed energy generation. This report compares interconnection processes for photovoltaic projects in California and Germany.
More than half of the electricity produced in the southeastern states is fuelled by coal. Although the region produces some coal, most of the states depend heavily on coal imports.
This case study covers the process of successfully integrating photovoltaic (PV) systems into a low-income housing development in northeast Denver, Colorado, focusing specifically on a new financing model and job training.
Over the last several years, solar energy technologies have been, or are in the process of being, deployed at unprecedented levels.
Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination.
The SunShot Vision Study explored the potential growth of solar markets if solar prices decreased by about 75% from 2010 to 2020.
The price of photovoltaic (PV) systems in the United States (i.e., the cost to the system owner) has dropped precipitously in recent years, led by substantial reductions in global PV module prices.
