The Best Solar Installers in Suffolk and Nassau Counties

1: Power Solutions – Highest Rated Long Island Solar Installer

Power Solutions is one of the most established names in solar. The advantage of this team is bespoke solutions tailored to the customer. Local solar experts offer a range of options from customizable and scalable battery solutions, like the Generac PWRcell 2 and Tesla Powerwall 3, to solar panels from top brands like REC and Qcells.

• Pros: Detailed cost/benefit analysis, on-site surveys including drone surveys, scaled solutions that balance budget and savings, and long-term 24/7 support.
• Cons: Not the cheapest solar installer, but Power Solutions is well-positioned for value, especially when considering the long-term return on investment, thanks to fully-customized arrays and battery storage.

Power Solutions has consistently maintained one of the highest customer ratings of any solar company in New York.

2: SUNation Energy – Most Recognizable Local Installer

SUNation is one of the most visible solar brands on Long Island. The company is based in Ronkonkoma and serves all of Long Island. Often considered a “big box” or “corporate” solar installer.

• Pros: Large and well-established local infrastructure makes the company efficient in both lead times and customer service delivery.
• Cons: The experience may feel less personal, with some customers reporting an overly inflexible and departmentalized process where communication may be slower during the permitting phase (a crucial step in completing a solar project).

3: EmPower Solar – Deep Local Experience/Premium Pricing

Empower is deeply committed to clean energy in the New York market and has strong local experience on Long Island.

• Pros: Focuses on high-efficiency hardware and has a reputation for professional and clean installations.
• Cons: Often perceived as one of the most expensive options on the market. Installation quality is excellent, but a higher upfront cost can extend the solar payback period.

4: GreenLogic – New Construction Expertise

Greenlogic has a strong presence on Long Island’s East End and is well-known for its ability to integrate solar into new construction projects.

• Pros: Strong established relationships with local architects and homebuilders, and experience with complex construction projects.
• Cons: Primarily focuses on the luxury segment, especially in the Hamptons. This can make scheduling and pricing less competitive for the average home in Western Suffolk or Nassau.

5: Hytech Solar – Price Matching

Hytech is rapidly growing and is known for aggressive price matching. It is one of the newest solar contractors on Long Island.

• Pros: Some of the lowest “cost-per-watt” quotes for budget-focused homeowners.
• Cons: Rapid growth and a focus on beating the market on cost leave little room for 1-on-1 consultation and custom engineering.
