Welcome to LISEIA

LISEIA is the Long Island Solar Energy Industries Association.

Through collaborative efforts, LISEIA seeks to ensure the proper growth and longevity of the solar industry on Long Island and beyond.

LISEIA is proud to be an official task force of NYSEIA, the New York Solar Energy Industries Association.

Collectively, LISEIA represents approximately 85% of Long Island's solar industry professional organizations, including contractors, suppliers, electrical inspectors, architects and engineers.

LISEIA also works collaboratively with many government and non-profit organizations, notably Renewable Energy Long Island, RELI, and all county, city, town and village governments, of whom we represent.

LISEIA general meetings are open to the public, and occur every third Wednesday of the month. Please join us and help support this vital industry.
