When someone in Gujarat starts getting solar quotes, two names frequently come up together: Heaven Green Energy and Adani Solar. The comparison is understandable but requires a clarification upfront — Adani Solar is primarily a panel manufacturer. When you receive a quote from an “Adani Solar installer,” you’re dealing with a third-party channel partner who has an authorisation to sell Adani-branded panels, not Adani’s own installation team.
This distinction matters for service quality, subsidy handling, and long-term support.
This post compares Heaven Green Energy and Adani Solar channel partners across the dimensions that actually determine your 25-year ownership experience — not just the day of installation.
Direct answer: Adani Solar panels are ALMM-listed quality products used widely across India, including by Heaven Green Energy on applicable projects. The meaningful comparison is between Heaven Green Energy (a direct EPC firm) and individual Adani channel partners (resellers whose service quality varies by partner). Heaven Green Energy is empanelled on all four Gujarat DISCOM portals for PM Suryaghar, is GEDA-empanelled for PM KUSUM, and offers a 10-year workmanship warranty — credentials that vary widely across channel partners.
Understanding the Business Models
Before comparing features, it helps to understand how each operates.
Heaven Green Energy is an independent solar EPC (Engineering, Procurement, and Construction) company. When you hire Heaven Green Energy, you’re working directly with the firm that designs your system, procures components, manages installation, handles subsidy paperwork, applies for net metering, and provides post-installation maintenance. The same company is responsible for your system from site survey to year 25.
Adani Solar is part of the Adani Group’s renewable energy business. Its primary business is manufacturing solar panels — it runs one of India’s largest panel factories in Mundra, Gujarat. Adani Solar sells panels through a network of authorized channel partners (dealers, distributors, installation companies). These partners quote under the “Adani Solar” brand, but they are independent businesses — not Adani employees or Adani subsidiaries.
This means “getting a quote from Adani Solar” actually means getting a quote from one of hundreds of authorized partners. Partner quality, service depth, subsidy capability, and post-installation support vary significantly from partner to partner.
💡 Fast tip
Heaven Green Energy installs Adani, Waaree, and Tata solar panels on relevant projects, depending on technical specifications and pricing. Being an independent EPC means we're not tied to one manufacturer's product line. We select panels based on what suits your roof, budget, and system design.
Dimension 1: Geographic Service Depth in Gujarat
Gujarat is a large and diverse state. A solar company that services Ahmedabad well may have no meaningful presence in Morbi, Bharuch, or Navsari.
Heaven Green Energy has salaried engineers based in Ahmedabad, Surat, Rajkot, Vadodara, Morbi, and 20+ other Gujarat locations. Service calls, AMC visits, and warranty claims are handled by this employed team.
An Adani Solar channel partner’s geographic coverage depends entirely on that partner’s team size. A partner based in Ahmedabad may install in Surat, but their post-installation service response in Surat may be slow or non-existent. Before signing with any channel partner, ask specifically: “Where is your service team based, and what is your SLA for a service call in my city?”
Dimension 2: PM Suryaghar Subsidy Handling
The PM Suryaghar Muft Bijli Yojana subsidy of up to ₹78,000 requires the installer to be registered on the pmsuryaghar.gov.in vendor portal, empanelled with your specific DISCOM, and capable of managing the online application process.
Heaven Green Energy is empanelled with all four Gujarat DISCOMs (UGVCL, DGVCL, PGVCL, MGVCL) and manages the complete subsidy application process — from portal registration to final subsidy disbursement. Our team has processed hundreds of successful subsidy claims.
Adani channel partners vary significantly. Some large partners are empanelled and handle the process competently. Others are not on the DISCOM portal at all, meaning you’d either lose the subsidy entirely or need to manage the application yourself.
This is not a hypothetical concern. According to data published by CEEW (Centre for Energy, Environment and Water), subsidy delays and denials are disproportionately concentrated among installations done by installers who were not properly empanelled at the time of installation. The CEEW India solar adoption report highlights this as a key barrier to residential solar adoption.
⚠️ Watch out
Before signing any solar contract, ask your installer to show you their empanelment letter from your DISCOM. Better yet, verify yourself on pmsuryaghar.gov.in by searching for the vendor's name or registration number. An unempanelled installer cannot get you the PM Suryaghar subsidy — a ₹78,000 loss you cannot recover after installation.
Read our detailed guide on PM Suryaghar in Gujarat for the full subsidy process: PM Suryaghar Gujarat complete guide.
Dimension 3: PM KUSUM Agricultural Solar
For agricultural connections and farmers looking to reduce diesel/grid costs through solar, PM KUSUM (Component B/C) requires installation by a GEDA (Gujarat Energy Development Agency)-empanelled contractor.
Heaven Green Energy is GEDA-empanelled for PM KUSUM. We handle the complete KUSUM application, subsidy documentation, and installation process for farmers across Gujarat. See our PM KUSUM service page for details.
Adani channel partners may or may not have GEDA empanelment. This is especially variable — many urban-focused channel partners have no KUSUM capability at all. If you’re a farmer or agricultural consumer, verify GEDA empanelment before shortlisting any installer.
Dimension 4: Post-Installation Support and Warranty
A solar system runs for 25 years. What happens in years 3, 7, or 15 matters as much as the installation day.
| Support Dimension | Heaven Green Energy | Adani Channel Partner |
|---|---|---|
| Workmanship warranty | 10 years | Typically 1–5 years (varies by partner) |
| Annual AMC option | Available (service plans) | Varies — many partners offer no formal AMC |
| Service response SLA | 48–72 hours across Gujarat | Varies; may be slow outside partner’s home city |
| Dedicated O&M team | Salaried in-house team | Usually outsourced or ad-hoc |
| Performance monitoring | Offered on request | Varies |
| Generation guarantee | Written kWh/year commitment available | Rarely provided in writing |
Panel manufacturers like Adani Solar provide product warranties (25-year performance guarantee on the panels themselves). But this is distinct from workmanship warranty (covering structural mounting, wiring, junction boxes, and installation quality). Workmanship warranty is the EPC’s responsibility — not the panel manufacturer’s.
If a wire corrodes at year 4 because it wasn’t properly sealed during installation, the panel manufacturer’s warranty doesn’t cover it. Your installer’s workmanship warranty does — if it exists and if the installer is still in business.
For a full explanation of what each warranty covers and what to look for in a solar contract, see our solar panel warranty explained guide.
Dimension 5: Panel Brand Selection
Heaven Green Energy is a panel-agnostic EPC. We install Adani, Waaree, Tata, and other ALMM-listed panel brands based on your project’s technical requirements, budget, and availability. This flexibility means you get the right panel for your situation — not just whatever the installer has agreed to push.
For a detailed comparison of panel brands available in Gujarat, see our solar brands Gujarat comparison guide.
An Adani channel partner primarily sells Adani-branded panels (that’s the point of the channel partnership). If Adani panels aren’t the best fit for your roof type, budget, or generation target, you may not hear that from a partner incentivised to sell Adani panels.
This doesn’t make Adani panels bad — they’re ALMM-listed and well-regarded. It just means you may not get objective brand advice from a branded channel partner.
Dimension 6: Pricing Transparency
Solar quotes can be structured in ways that obscure the real cost per component.
Heaven Green Energy provides itemised quotes breaking down:
- Panel cost per watt (model number, wattage, brand specified)
- Inverter cost (model number, capacity, warranty specified)
- Balance of System (mounting structure, wiring, DCDB/ACDB, earthing, lightning arrester)
- Installation labour
- Net metering application fee
- PM Suryaghar subsidy handling (included at no extra charge)
A channel partner quote may present a single “total system cost” or lump-sum figure without line-item detail. This makes it impossible to evaluate whether you’re getting quality components at fair prices or low-grade components at inflated labour rates.
The local vs national solar EPC cost comparison covers this in more detail.
💰 Real numbers
A 3 kW system quote should show: panels (~₹45,000–₹55,000), inverter (~₹25,000–₹35,000), mounting structure (~₹15,000–₹20,000), wiring/BOS (~₹12,000–₹18,000), installation labour (~₹12,000–₹15,000), net metering application (~₹3,000–₹5,000). Total before subsidy: ₹1,12,000–₹1,43,000 in a competitive Gujarat market. If a quote is significantly below this, ask what's been cut.

The EPC Quality Audit Framework: 8 Checkpoints
Before signing with any solar installer in Gujarat — including Adani channel partners, other brands, or Heaven Green Energy — verify these 8 points. We call this the EPC Quality Audit Framework.
-
Are they on your DISCOM’s PM Suryaghar empanelled vendor list? Check at pmsuryaghar.gov.in by searching the vendor portal. A “yes” from the installer is not enough — verify the registration yourself.
-
Do they have GST registration? Ask for their GSTIN (15-digit number starting with your state code). Verify it at gst.gov.in. Unregistered solar sellers cannot issue valid tax invoices, which affects your ability to claim subsidy and file insurance claims.
-
Do they have a registered office — not just a mobile number? An installer with a physical office, registered on the MCA portal, is far less likely to disappear after installation. Check the MCA (Ministry of Corporate Affairs) website or ask for their company registration number.
-
Do they specify an ALMM-listed panel model in the quote? ALMM (Approved List of Models and Manufacturers) is the MNRE’s quality registry. Only ALMM-listed panels qualify for PM Suryaghar subsidy. Your quote must name a specific panel model — not just “solar panel, 550 W.” Verify the model at solarrooftop.gov.in.
-
Do they specify a BIS/IEC-certified inverter model? The inverter should carry BIS certification (or IEC equivalence). Ask for the inverter model number and check for BIS mark. Uncertified inverters can void insurance and fail DISCOM inspection.
-
Do they include net metering application in scope? Net metering application, DISCOM inspection coordination, and bi-directional meter installation should be included in your contract. If it’s listed as an extra or not mentioned, clarify before signing.
-
Do they provide a performance guarantee (kWh/year commitment in writing)? Any credible installer can tell you — in writing — how many units your system will generate per year. If they refuse or say “it depends on weather,” that’s insufficient. A professionally designed system has a calculable P50 and P90 generation figure.
-
Do they have a dedicated O&M team (not “call us if there’s a problem”)? Ask specifically: “Who will respond to a service call? How soon? Are they your employees or are they subcontracted?” A salaried in-house team is far more reliable than a reactive network of subcontractors.
Heaven Green Energy answers Yes to all 8 of these checkpoints. We encourage every prospective customer to run any installer — including us — through this framework before committing.

What the Independent Research Says
Bridge to India, one of India’s leading solar market research firms, estimates that installation quality and post-sale service are the top two factors driving customer satisfaction variance in rooftop solar — ahead of panel brand and even system price. Their research consistently shows that EPC firms with direct installation teams outperform dealer/channel networks on after-sales satisfaction.
The CEEW residential solar report found that approximately 30% of residential solar complaints in India relate to subsidy delays caused by installer-side application errors — most of which occur at smaller or less-experienced channel partners.
MNRE’s empanelment data shows that empanelment requirements have tightened since 2023 — installers must now demonstrate project history, technical staff credentials, and financial stability to be listed on DISCOM portals. This has narrowed the quality gap but hasn’t eliminated it.

Step-by-Step: How to Evaluate Any Gujarat Solar Installer
- Ask for their DISCOM empanelment reference number and verify it at pmsuryaghar.gov.in. This takes 5 minutes and is the single most important check.
- Request an itemised quote with panel model, inverter model, and warranty terms listed separately. Decline any quote that won’t show line items.
- Ask for 3 references from installations in your city completed in the past 12 months. Contact them and ask about the subsidy process timeline and any post-install issues.
- Run the 8-point EPC Quality Audit Framework listed above. Note which checkpoints the installer passes or fails.
- Compare workmanship warranty terms. Get them in writing — not verbal assurances. A 10-year workmanship warranty should be in the signed contract.
- Confirm net metering is included in scope. Ask who submits the DISCOM application and who coordinates the meter installation.
- Ask for a written generation estimate (kWh/year) with the assumptions stated (roof orientation, tilt, shade factor, system efficiency).
- Get 2–3 quotes. Not to find the cheapest price, but to compare component specifications and warranty terms side by side.
Frequently Asked Questions
Is Adani Solar the same as the Adani Group installer?
No. Adani Solar is the panel manufacturing division of Adani Group. When you receive a solar quote branded as “Adani Solar,” you are dealing with an authorised channel partner — an independent company licensed to distribute Adani panels. Adani Group does not typically send its own engineers to install residential rooftop systems.
Do Adani Solar panels qualify for PM Suryaghar subsidy?
Yes. Adani Solar panels are on the MNRE’s ALMM (Approved List of Models and Manufacturers), making them eligible for PM Suryaghar subsidy. The relevant question is whether your installer (not the panel brand) is empanelled on your DISCOM’s vendor portal to process the subsidy application.
Does Heaven Green Energy install Adani Solar panels?
Yes. Heaven Green Energy is a panel-agnostic EPC. We install Adani, Waaree, Tata, and other ALMM-listed panel brands depending on project requirements, pricing, and availability at the time of installation. We do not have any exclusive arrangement that limits us to one brand.
What is the difference between a panel warranty and a workmanship warranty?
A panel manufacturer’s warranty covers the panels themselves — typically a 25-year performance warranty and a 10-year product warranty. A workmanship warranty covers the quality of installation: mounting, wiring, electrical connections, and structural work. If a wire corrodes or a bracket fails because of installation error, the workmanship warranty covers the repair cost. This is the EPC’s responsibility, not the panel manufacturer’s.
How do I verify if an installer is empanelled for PM Suryaghar in Gujarat?
Go to pmsuryaghar.gov.in and navigate to the vendor/installer registration section. Search for the company by name or DISCOM. Gujarat has four DISCOMs — UGVCL (north Gujarat), DGVCL (south Gujarat), PGVCL (Saurashtra), MGVCL (Madhya Gujarat). Your installer should be empanelled on the portal for your specific DISCOM.
What is the PM KUSUM scheme and how is it different from PM Suryaghar?
PM Suryaghar (Muft Bijli Yojana) is for residential rooftop solar. PM KUSUM is for agricultural connections — it subsidises solar pumps and feeder-level solar for farmers. PM KUSUM in Gujarat requires GEDA (Gujarat Energy Development Agency) empanelment, not just DISCOM empanelment. Heaven Green Energy holds GEDA empanelment for PM KUSUM work.
Is a 10-year workmanship warranty standard in Gujarat?
No, it’s above market standard. Most Gujarat installers offer 1–5 years of workmanship warranty. Heaven Green Energy provides a 10-year workmanship warranty as standard on all residential installations, reflecting confidence in installation quality built through 10,000+ completed projects.
How does Heaven Green Energy compare to large national solar brands?
This is covered in detail in our local vs national solar EPC comparison. The short version: large national brands have brand recognition but often execute through local subcontractors with variable quality. Heaven Green Energy uses its own salaried team for installation and service across Gujarat, which provides tighter quality control and faster post-install response.
What if I already have Adani Solar panels installed and want service support?
If your existing installer is unavailable or unresponsive, Heaven Green Energy can provide AMC (Annual Maintenance Contract) services for systems installed by other companies, including those with Adani Solar panels. Contact us with your system details for an AMC quote.
