What GreenLogic does
GreenLogic is a privately held solar engineering, procurement, and construction (EPC) firm headquartered in Roslyn Heights, New York, founded in 2005 by Nick Albukrek and Marc Clejan. The company designs, sells, and installs custom photovoltaic (PV) and battery storage systems for residential homeowners, commercial businesses, small businesses, and new construction builders/architects across Long Island's Nassau and Suffolk counties, with three operating offices (Roslyn Heights, Manorville, Southampton), 101–250 employees, more than 3,000 lifetime installations across 100+ townships, and a stated $500M+ in cumulative client savings since inception.
The core technology stack is built on third-party hardware from premium partners — SunPower panels for PV modules and Tesla Powerwall and Enphase IQ Batteries for storage — layered with an internally developed set of system performance prediction and tracking tools used to size and validate installations. GreenLogic holds NYSERDA Quality Solar Installer Gold Status, the state's highest quality designation, and has received SunPower's Excellence in Solar Design and Installation Award four times, most recently in 2023. Customer-facing offerings include custom residential systems ($20,000–$60,000), commercial systems ($50,000–$500,000), Tesla and Enphase battery retrofits, new construction solar integration, and Power Purchase Agreements (PPAs) priced at $0.16/kWh with no annual escalator.
GreenLogic operates a sales-led, direct-to-consumer go-to-market model built around free in-person energy consultations performed by an in-house consulting team (no subcontracted installers), supported by a customer referral program paying up to $2,250 per converted referral and content marketing via blog, Facebook, and Instagram. Revenue is generated from one-time hardware sales, recurring PPA subscription fees routed through third-party system owners, and battery storage unit sales, with federal (30% ITC through 2032), New York State (up to $5,000 tax credit), and PSEG LI battery rebates (up to $6,250) explicitly marketed to lower customer acquisition friction. The company is bootstrapped, profitable, founder-controlled, and has not disclosed institutional capital, M&A activity, or geographic expansion beyond Long Island.

- Solar for Small Businesses Specialized solar PV solutions for Long Island small businesses including farms, retail shops, offices, private schools, and workshops under 12,000 square feet. Service includes presale energy analysis and PSEG LI account review with access to commercial financing and incentive programs.
- Solar + Battery Backup Home solar battery backup systems that store energy for use at night, during grid outages, or to avoid peak demand charges. Includes authorized installation of Tesla Powerwall integrated battery systems and Enphase IQ Battery (NEMA 3R rated) systems capable of powering HVACs and pool pumps, with Storm Guard feature for automatic pre-storm charging.
- Power Purchase Agreement (PPA) Solar financing arrangement in which a third party owns the PV system on the customer's property and the customer purchases the electricity generated at a fixed rate lower than utility rates. GreenLogic designs and installs the system; the third-party owner operates and maintains it. PPA rates are as low as $0.16 per kWh with no annual escalator and $0 upfront cost, with customers saving 25-35% on solar electricity produced starting in the first month.

GreenLogic competitors and assessment
Company assessmentDirect peers
- Trinity Solar: Trinity Solar is one of the largest privately held residential solar installers in the Northeast U.S., serving New York, New Jersey, Massachusetts, Connecticut, and surrounding states. It is highly comparable in size, regional concentration, and direct-to-homeowner sales motion.
- Sunrun: Sunrun is the largest U.S. residential solar, battery storage, and energy services company with national reach and a strong PPA/lease business model. It directly competes with GreenLogic for residential customers in NY and uses a similar subscription-style approach.
- Momentum Solar: Momentum Solar is a residential solar installer operating on the East Coast including New York, New Jersey, and Massachusetts. It offers in-house installation, battery storage, and direct sales—closely matching GreenLogic's residential offering and NY metro geography.
- Freedom Forever: Freedom Forever is a large U.S. residential solar installer operating across multiple states with a direct sales force and in-house installation teams. Its business model—custom-designed systems, direct-to-consumer, no subcontractors—closely mirrors GreenLogic's approach.
- Vivint Solar (now Sunrun): Vivint Solar (acquired by Sunrun) was a leading residential solar installer with a national direct-sales model combining solar and battery storage. It competes directly in the same residential solar PPA/lease segment GreenLogic serves.
Regional players
- All Energy Solar: All Energy Solar is a regional solar installer serving the Northeast U.S. including parts of New York. It offers residential and commercial solar with battery storage, providing regional competitive overlap with GreenLogic's NY footprint.
- Long Island Solar Power: Long Island Solar Power is a regional solar installer based on Long Island serving the same Nassau and Suffolk county market as GreenLogic. It directly competes in residential and commercial solar with a similar local direct-sales approach.
Others
- Enphase Energy: Enphase is a leading supplier of microinverters and battery storage systems (IQ Batteries) used in residential and commercial solar. While GreenLogic is an Enphase installer partner, Enphase's Installer Network and growing direct platform makes it an adjacent competitive influence on the residential solar ecosystem.
Broad incumbents
- SunPower (now Complete Solar): SunPower is a long-established solar panel manufacturer and installer with a national dealer network. GreenLogic is a SunPower Master Dealer, but SunPower also sells and installs directly in some markets, overlapping in residential and commercial segments.
- Tesla Energy: Tesla designs, installs, and finances residential and commercial solar (Solar Roof) and Powerwall battery systems nationally. While GreenLogic is a Tesla Powerwall installer partner, Tesla also competes for end customers directly as a vertically integrated solar and storage provider.
