Most of the solar-energy projects completed in New Jersey are located in the central part of the state, according to data from theNew Jersey Clean Energy Program.

Home owners, businesses, schools and others have built nearly 33,000 solar installations throughout the state through the end of January, the NJCEP data shows. These systems have a capacity of more than 1.4 million kilowatts- enough energy to power 14 million 100-watt light bulbs for an hour apiece.
