Michael Drewniak, a spokesman for Governor Christie, didn't immediately respond to a phone message or e-mail seeking comment today.
"We're pretty confident the governor will sign it," Jeff Tittel, director of the Sierra Club in New Jersey, said in an interview. "The legislature has been working with Christie's team to ensure his support."
'Financial Albatross'
New Jersey developers added 174 megawatts of photovoltaic panels in the first quarter, surpassing California as the largest solar state with 34 percent of all U.S. installations, according to the Solar Energy Industries Association.
New Jersey's draft 2011 Energy Master Plan referred to an incentive program for solar energy as a "financial albatross." The phrase was removed in the final version, which cut the state's renewable-energy goal to 22.5 percent of all power sources from 30 percent by 2021.
