2. EnergySage
EnergySage is not a traditional solar installer but a powerful online marketplace, earning its spot as one of the best resources for Long Island residents. It functions as a neutral intermediary, allowing homeowners and business owners from Hempstead to Montauk to receive multiple, competitive quotes from a network of pre-screened local and regional solar companies. This approach demystifies the shopping process and empowers you with transparent, comparable data before making a commitment.
The platform’s strength lies in its standardized quote system. Instead of deciphering different proposals, you can compare key metrics like cost per watt, equipment brands, warranty terms, and financing options in an easy-to-read, side-by-side format. This "apples-to-apples" comparison is a significant advantage, helping you identify the best value and avoid overpaying.
Key Features and User Experience
EnergySage provides a wealth of educational resources tailored to New York. Users can access up-to-date information on the NY-Sun Megawatt Block Incentive, federal tax credits, and Long Island-specific utility programs. The platform's interface is clean and user-friendly, guiding you through the process of creating a property profile and requesting quotes. An internal messaging system keeps all communication with potential installers organized in one place.
- Product Selection: Access to a wide variety of solar panel and inverter brands through multiple installers.
- Customer Service: An assigned Energy Advisor can help you navigate quotes and answer questions.
- Availability: Free to use for all homeowners and commercial property owners across Long Island.
Pro Tip: When using EnergySage, pay close attention to the installer's local experience and reviews. While the platform vets for licensing and insurance, a company with a strong track record in your specific town or utility territory (PSEG Long Island) is often a better choice.
Pros & Cons
| Pros | Cons |
|---|---|
| Transparent Comparison: Easily compare multiple quotes side-by-side to find the best value. | Final Vetting Required: You are still responsible for reviewing the final contract. |
| Vetted Installers: All companies on the platform are pre-screened for quality and credentials. | Persistent Follow-up: Some installers may be aggressive with their follow-up calls. |
| Educational Resources: Access to NY-specific data on pricing, incentives, and savings. | Not a Direct Installer: EnergySage is a marketplace, not the company doing the work. |
For those just beginning their solar journey, EnergySage is an invaluable tool for market research and initial pricing. It helps you understand the core differences between solar panels vs. traditional energy sources on Long Island and provides the confidence needed to engage with installers directly.

3. SolarReviews
SolarReviews operates as a comprehensive research and due diligence platform, making it a crucial stop for any Long Island resident considering a solar investment. Rather than being a marketplace, it functions as an extensive database of consumer reviews, installer profiles, and regional cost data. This allows homeowners from Suffolk to Nassau County to thoroughly vet potential installers, verify their reputations, and gain a clear understanding of market pricing before signing any contracts.
The platform’s primary value is its focus on transparency and education. By publishing state-level cost-per-watt data and detailed equipment comparisons, it equips you with the knowledge needed to critically evaluate quotes you receive from direct installers or marketplaces. This context is invaluable for determining if a bid is competitive and ensuring you are getting high-quality components for your home or business.
Key Features and User Experience
SolarReviews offers a suite of free tools designed to empower the consumer. Its cost and savings calculators provide realistic budget estimates tailored to the Long Island area, factoring in local utility rates and New York-specific incentives. The platform features an impressive library of buying guides that break down complex topics, from panel efficiency to inverter types, in simple, non-technical language. The user interface is straightforward, making it easy to search for local installers and read verified customer reviews.
- Product Selection: Features detailed comparisons and reviews on a wide range of solar panels, inverters, and battery brands.
- Customer Service: As an information-only site, direct customer service is limited; its value lies in the self-service resources.
- Availability: The platform and its resources are freely accessible to all users across Long Island.
Pro Tip: Use the SolarReviews cost-per-watt benchmarks for New York as a reference when you receive quotes. If an installer’s price is significantly higher, you have the data to ask for a justification or negotiate for a better deal.
Pros & Cons
| Pros | Cons |
|---|---|
| Excellent for Due Diligence: In-depth reviews and profiles help you vet local companies. | Information Only: It’s a research tool, not a platform for managing contracts. |
| Provides Cost Context: Pricing data helps you evaluate quotes and avoid overpaying. | Inconsistent Review Volume: Not every installer will have a large number of recent reviews. |
| Unbiased Equipment Guides: Helps you understand the technical side of your investment. | Does Not Generate Quotes: You must still reach out to installers or use a marketplace. |
For property owners who want to be well-informed before engaging with sales representatives, SolarReviews is an indispensable resource. It provides the background knowledge needed to confidently navigate the process of finding one of the best solar companies Long Island has to offer.

4. NYSERDA "Find a Contractor" (NY-Sun)
While not a direct installer, the NYSERDA "Find a Contractor" tool is a foundational resource for anyone serious about going solar on Long Island. This official directory for the NY-Sun program is the most reliable way to verify that a solar company is eligible to offer state-level incentives, including the valuable NY-Sun Megawatt Block incentive. It serves as a crucial first step for due diligence, ensuring you engage with contractors who are compliant with New York State's standards.
The platform's primary strength is its direct link to state-backed quality assurance. It allows homeowners and business owners from Elmont to Riverhead to filter through a list of participating contractors who are authorized to handle all the necessary incentive paperwork on their behalf. This significantly reduces the risk of working with a non-compliant installer and potentially losing out on thousands of dollars in rebates.
Key Features and User Experience
NYSERDA's directory stands out by awarding Quality Solar Installer (QSI) designations. Contractors can earn a Gold or Platinum badge based on multi-year performance, quality inspection scores, and installation volume. This provides an at-a-glance indicator of a company’s track record and commitment to high standards. While the interface is more utilitarian than a commercial marketplace, its search functionality is straightforward, allowing you to find local providers efficiently.
- Product Selection: The directory lists contractors; the specific panels, inverters, and batteries they offer will vary by company.
- Customer Service: As a state-run directory, it does not offer direct customer service for installations but provides guidance on selecting a contractor.
- Availability: A free public resource for all New York residents, including everyone on Long Island.
Pro Tip: Use the QSI designations to create your initial shortlist. A company with a Gold or Platinum rating has a proven, multi-year history of quality installations as judged by NYSERDA's own inspection process, making them a lower-risk choice.
Pros & Cons
| Pros | Cons |
|---|---|
| Authoritative Vetting: All listed contractors are authorized to participate in NY-Sun incentives. | Basic Interface: The user experience is more functional than a polished consumer website. |
| Quality Indicators: The QSI (Gold/Platinum) system helps identify top-performing installers. | No Endorsement: NYSERDA lists participants but doesn't guarantee any individual company's work. |
| Direct Incentive Link: Ensures the contractor you choose can secure your state-level rebates. | Requires Further Research: It's a directory, so you must still gather and compare quotes yourself. |
For Long Island property owners, starting your search with the NYSERDA directory is a smart, strategic move. It helps create a vetted list of potential partners, making it one of the most important tools for finding the best solar companies Long Island has to offer and ensuring your project qualifies for every available state incentive.

5. PSEG Long Island (Solar Hub & Participating Contractors)
As Long Island's primary utility, PSEG Long Island offers a vital resource for anyone considering solar, even though it is not an installer itself. Its Solar Hub is an essential starting point for homeowners and businesses from Huntington to the Hamptons, providing direct access to information on local programs, incentives, and the all-important interconnection process. This platform helps you understand how a solar project aligns with the local grid and financial programs before you even speak to a contractor.
The key strength of this resource is its official "Participating Contractors" list. These are installers who are approved to work within the NY-Sun program framework and are familiar with PSEG-LI’s specific technical requirements for connecting to the grid. By starting your search here, you can be confident that you are engaging with companies that understand the local utility landscape, which can prevent significant delays and complications down the line.
Key Features and User Experience
PSEG Long Island's Solar Hub acts as a centralized source of truth for utility-specific solar information. It provides clear details on programs like the Battery Storage Rewards incentive and community solar options, which are crucial for maximizing your return on investment.

Pros & Cons
| Pros | Cons |
|---|---|
| Local Utility Context: Provides official guidance on interconnection and local programs. | Not a Price-Comparison Tool: You must contact each contractor individually for proposals. |
| Vetted Contractor List: All listed contractors are aligned with the NY-Sun program framework. | No Endorsement: PSEG-LI does not endorse any specific installer; the list is informational. |
| Incentive Information: Direct links to details on battery rewards and other NY incentives. | Limited Scope: The resource focuses on utility interaction, not the full customer journey. |
For Long Island residents, consulting the PSEG-LI Solar Hub is a critical step in the due diligence process. It ensures your project is compatible with local regulations from the start and helps you find qualified installers who are among the best solar companies Long Island has to offer.
