The solar energy market is booming in Massachusetts, as commercial building owners, municipalities, and name-brand retailers like REI and Kohl’s take advantage of state incentives that have made it more affordable to fund solar power projects.
Even as activity has slowed in several other key states, the number of installations here has grown so steadily that the Solar Energy Industries Association, a national trade group, expects Massachusetts to rank in the top 10 among states that will add the most solar power this year.

Capacity vs output needs to be clarified; all PV systems yeild 25% of output in consideration of insolation. 250 GW or solar capacity is approximately 62.5 GW of useful power. It would be nice if the industry would rate their 'success' accordingly by reminding the public of the intermittency of the source which leads to massive back-up requirements on the gird which are both costly and fossil-fuel fired.
