EmPower Solar was co-founded in 2003 by David G. Schieren and Gregory D. Sachs with an ambitious vision: to make solar energy the dominant energy source in New York and beyond. The company’s roots trace back to pioneering work in renewable energy storage, including hydrogen fuel cell projects like the U.S. Department of Energy Solar Decathlon House and a solar-and-wind-powered hydrogen fueling station in the Town of Hempstead. That early work in energy storage—using solar electricity to split water through electrolysis—gave the founders confidence in solar’s capabilities and set the stage for what would become one of Long Island’s premier solar installation companies. Based in Bethpage, NY, this solar installer in Bethpage has grown steadily over two decades through organic expansion and word-of-mouth. Today, EmPower Solar employs approximately 100 full-time workers across three New York locations and has installed over 5,000 residential and commercial solar energy systems, totaling more than 50 megawatts of distributed solar across the Long Island and greater NYC area. The company proudly serves Nassau, Queens, Suffolk, Brooklyn, Staten Island, and Westchester communities—putting solar panels on homes throughout New York’s most populous region. EmPower Solar operates as a full-service solar power development company, handling every step under one roof: sales, design and engineering, permitting, in-house installation, and long-term customer service and care. The company holds NABCEP certification (092907-25) and has earned recognition including the NYSERDA Quality Solar Installer award. Schieren, who holds a Master of Science in Energy Management from the New York Institute of Technology and chairs the New York State Solar Energy Industry Association (NYSEIA), has testified before Congress and remains a vocal advocate for clean energy policy. EmPower Solar’s mission extends beyond solar panels alone. The company emphasizes total home electrification, offering complete solar installation systems paired with Tesla Powerwall and other battery storage solutions for backup power, EV charging stations for electric vehicle owners, SPAN smart service panels, and even time-of-day utility rate analysis to maximize savings for New York homeowners. EmPower partners with premium manufacturers including Tesla, SunPower, REC, QCells, and Enphase, and backs all installations with a 25-year comprehensive workmanship warranty and a five-year production guarantee. The company’s client-focused culture, which they call the ‘EmPowering Way,’ emphasizes professionalism, teamwork, excellence, and commitment to clean energy. To date, EmPower Solar has saved clients more than $20 million in avoided energy costs and has deployed over 150 battery storage systems. The company is also active in community engagement, including partnerships with New York City FC and local STEM education programs. For Long Island and NYC homeowners looking to reduce energy costs, achieve energy independence, and transition to clean solar energy, EmPower Solar delivers local expertise, premium technology, and service that extends across the 25-plus-year lifespan of every system they install.
