Commercial electricity rates on Long Island rank among the most expensive in the country. A well-designed solar system reduces your operating costs from day one, improves your net operating income, and insulates your business against future rate hikes. Most commercial systems achieve full payback in 5 to 7 years and then produce free power for decades. GreenLogic clients have saved a combined $500M+ to date, and MACRS accelerated depreciation is available for qualifying businesses.

What Nobody Tells You
Our Infrequently Asked Questions section will shed some light on the things Long Island business owners need to know before going solar, and the questions worth asking, even if you haven't thought to ask them yet.
Why choose a local company over a large national chain, especially for commercial projects?
GreenLogic is extremely well connected with the local utility. Solar is still a new industry and even the local utility is encountering new hurdles every day. GreenLogic has a long history of coming up with innovative solutions that allow previously rejected projects to move forward.
How much does commercial solar cost on Long Island?
The cost depends on your system size, roof type, and energy consumption. Most Long Island commercial systems range from $50,000 to $500,000 before incentives. With MACRS accelerated depreciation, the federal ITC for qualifying projects, and zero-down financing options, many businesses see a net payback in 5 to 7 years and generate effectively free power for decades after that. GreenLogic models your specific numbers before you commit to anything.
How long does a commercial solar installation take?
Most commercial installations take anywhere from a few days to a few weeks, depending on system size and roof complexity. The full process from contract to energization typically runs 3 to 6 months, with permitting and PSEG LI interconnection driving most of the timeline. GreenLogic manages every step and has over two decades of experience navigating the approval process across every Suffolk and Nassau County municipality.
Will solar work for my building if I lease rather than own it?
It depends on your lease terms. Some commercial tenants successfully install solar with landlord approval and a lease rider. In other cases, a power purchase agreement structure may be a better fit. GreenLogic has worked through both scenarios and can help you figure out what makes sense for your specific situation before any money changes hands.
What happens on cloudy days or during winter?
Commercial solar systems produce power year-round, including on overcast days. Production is lower in winter months, but Long Island averages more than 200 sunny days per year, and PSEG LI net metering credits surplus summer generation against lower-output months. Your system is designed around your annual consumption profile, not just peak production days.
Does my roof need to be replaced before installing solar?
Not necessarily, but we do assess roof condition as part of every pre-sale analysis. If your roof has less than 10 years of useful life remaining, we'll flag it so you can address it before installation rather than after. Getting ahead of a roof replacement saves time and avoids the cost of temporarily removing and reinstalling panels later.
