Long Island’s chief solar-industry group is combining forces with a state solar group to give it a bigger voice in Albany. The group has also expanded its reach to further embrace energy-storage solutions.

The group, formerly known as the Long Island Solar Energy Industries Association, is now the Long Island Solar & Storage Alliance, operating as a subcommittee of the New York Solar Energy Industries Association.

Tara McDermott, chairwoman of the alliance and a director at EmPower Solar, an Island Park solar contractor, said the move will combine the strengths of the two groups, while allowing the alliance to focus on issues particular to Long Island, which vastly leads the state in solar installations.

“Instead of two separate organizations, we’re now working as one,” she said, pointing to recent successes in working with LIPA to enhance community solar programs that give customers access to cheaper power without panels on their roofs. LIPA also committed to meetings with local industry leaders through the group to work toward the state goal of more green energy.
