Solar Subsidies in Bihar: A Vendor Selection Guide
How choosing the wrong installer can invalidate your PM Surya Ghar subsidy before you even apply
Learn how to verify empanelled vendor status, demand the right documentation, and spot red flags that could get your Bihar rooftop solar subsidy rejected. A step-by-step guide for NBPDCL and SBPDCL homeowners.
TL;DR
Empanelment is a subsidy prerequisite, not a quality badge â If your installer isn't registered on the national solar rooftop portal under your specific Bihar DISCOM (NBPDCL or SBPDCL), your subsidy application cannot even be filed.
Verify before you pay â Check the national portal's statewise vendor list yourself. Do not accept screenshots, verbal claims, or "pending empanelment" as proof.
Sequence matters as much as the installation itself â DISCOM feasibility approval must come before installation. Installing first and applying later breaks the subsidy chain.
Get subsidy commitments in writing â Your contract should specify the vendor's responsibility for portal submissions, DISCOM coordination, and net metering, with clear remedies if they fail to deliver.
Check references for actual subsidy receipt â Ask for past customers who have the subsidy money in their bank account, not just panels on their roof. One phone call can save you â¹78,000.
Guide Orientation: What This Guide Covers and Who It's For
This guide helps Bihar homeowners choose the right empanelled vendors for residential rooftop solar installation, specifically to protect their eligibility for solar subsidies under the PM Surya Ghar Yojna. It is written for homeowners in NBPDCL and SBPDCL service areas who are considering a rooftop system in the 1 kW to 10 kW range.
By the end, you'll understand exactly how to verify an installer's empanelment status, what documentation to demand before signing anything, and how to spot the warning signs that separate legitimate vendors from those who will leave your subsidy application stuck or rejected.
This guide does not cover commercial or industrial solar installations, off-grid systems, or states outside Bihar. It focuses narrowly on vendor selection as a subsidy-eligibility decision, not a general quality-comparison exercise.
Why Choosing the Right Empanelled Vendor Matters for Solar Subsidies
In Bihar, your solar subsidy doesn't depend only on your roof, your documents, or your system size. It depends on who installs it. Under the PM Surya Ghar framework, MNRE requires vendors to complete a prescribed registration process before they can operate under the scheme. If your installer hasn't done this, your subsidy claim path is blocked from day one.
This is where Bihar homeowners face a specific, local risk. The state's rooftop solar market is growing fast. Bihar's renewable energy policy targeted 1,000 MW of rooftop solar as part of a broader push, and that growth has attracted both legitimate installers and opportunistic operators who promise subsidies they cannot deliver.
The cost of choosing wrong is not just a bad installation. It's a â¹78,000 subsidy (on a 3 kW system) that never arrives. It's a DISCOM approval process that stalls because the vendor isn't in the system. It's months of follow-up calls that go nowhere. And in many cases, homeowners discover the problem only after the panels are already on the roof and the money has been paid.
Bihar's 2025 energy policy draft confirms that BREDA facilitates subsidies through government agencies, meaning the official channel is not optional. It is the only path. Your vendor choice is the gate that opens or closes that path.
Core Concepts: Understanding Empanelment, DISCOMs, and the Subsidy Chain
What "Empanelled" Actually Means
An empanelled vendor is an installer who has been officially registered on the national solar rooftop portal and approved to work under the PM Surya Ghar Yojna in a specific DISCOM area. This is not a quality certification or a customer review score. It is a bureaucratic prerequisite: without it, the vendor cannot submit your installation details through the portal, and your subsidy application cannot proceed.
Bihar's DISCOM Structure
Bihar has two main power distribution companies: NBPDCL (North Bihar Power Distribution Company Limited) serving north Bihar, and SBPDCL (South Bihar Power Distribution Company Limited) serving south Bihar. Both fall under BSPHCL. Your vendor must be empanelled under the correct DISCOM for your area. North Bihar's DISCOM appears in the official statewise vendor list under the simplified rooftop solar framework.
The Subsidy Chain: How the Money Flows
The subsidy is not a discount your installer gives you. It flows from the central government, through MNRE, to the DISCOM, and then to your bank account after your installation is verified and your net meter is commissioned. Every link in this chain requires your vendor to be in the system. If any link breaks, the money stops.
Common Misconception: "Any Installer Can Get You the Subsidy"
This is the single most expensive misconception in Bihar's solar market. Many installers will tell you they can "handle the subsidy paperwork" or that they are "in the process of getting empanelled." Neither of these statements means they are currently authorized. If they are not on the portal today, your application cannot be filed today.
The Vendor Selection Framework: Eligibility First, Everything Else Second
Most homeowners approach vendor selection by comparing prices, panel brands, and warranty terms. These factors matter, but they are secondary. In Bihar, the correct framework inverts the priority:
Stage 1: Eligibility Verification â Confirm the vendor is empanelled under your DISCOM on the national portal.
Stage 2: Documentation Audit â Verify the vendor's documentation practices match what the DISCOM and portal require.
Stage 3: Process Alignment â Ensure the vendor follows the correct sequence (DISCOM approval before installation, not after).
Stage 4: Commercial Evaluation â Only now compare pricing, equipment, and terms.
Stage 5: Contractual Protection â Lock in commitments about subsidy facilitation, timelines, and accountability in writing.
This framework ensures you never waste time evaluating a vendor who cannot legally deliver your subsidy. Each stage acts as a filter. A vendor who fails Stage 1 is eliminated before you ever discuss price.
Step-by-Step: How to Choose an Empanelled Installer in Bihar
Step 1: Verify Empanelment Status on the National Portal
Objective: Confirm, with your own eyes, that the vendor appears in the official database for your DISCOM area.
Go to the national solar rooftop portal's statewise vendor list. Select Bihar. Select your DISCOM (NBPDCL or SBPDCL). Look for the vendor's company name in the results. If they appear, note their registration number. If they don't appear, stop the conversation.
Do not accept screenshots from the vendor as proof. Do not accept "we are listed under a different name" as an explanation without verifying it yourself. The portal is publicly accessible and free. There is no reason to take anyone's word for it.
Anti-patterns to avoid: Trusting a vendor's claim that they are "about to be empanelled" or that their empanelment is "under a partner company." Both are common tactics used by unregistered operators. Also avoid confusing MNRE channel partner listings with DISCOM-specific empanelment; they are different things.
Success indicator: You have the vendor's name and registration number from the portal, confirmed by your own search.
Step 2: Confirm DISCOM-Specific Authorization
Objective: Ensure the vendor is authorized to operate in your specific DISCOM territory, not just "in Bihar."
Empanelment is DISCOM-specific. A vendor empanelled under NBPDCL cannot necessarily process your application if your electricity connection is under SBPDCL, and vice versa. Check your electricity bill to confirm which DISCOM serves your home. Then cross-reference with the vendor's listing on the portal.
This step catches a surprisingly common problem. Some vendors operate across multiple districts but are only empanelled in one DISCOM area. They may install your system, but when it comes time to submit the application, the portal rejects it because the vendor-DISCOM pairing doesn't match.
Anti-patterns to avoid: Assuming that because a vendor has done installations in your city, they are empanelled under your DISCOM. Geography and DISCOM boundaries don't always align neatly in Bihar.
Success indicator: Your electricity bill's DISCOM matches the vendor's empanelment DISCOM on the portal.
Step 3: Audit the Vendor's Documentation Process
Objective: Verify that the vendor follows proper documentation practices that will survive DISCOM scrutiny.
Before signing anything, ask the vendor to walk you through the documents they will prepare and submit. At minimum, the process requires: your identity proof, electricity bill, bank account details (for subsidy disbursement), roof ownership proof, and a technical feasibility report. The vendor should be able to list these without hesitation.
More importantly, ask how they handle the DISCOM approval process. A legitimate empanelled vendor will explain that DISCOM technical feasibility approval must come before installation begins. If a vendor says "we'll install first and handle the paperwork later," that is a red flag. The correct sequence is: apply on portal, get DISCOM feasibility approval, install, request DISCOM inspection, get net meter commissioned, then receive subsidy.
Anti-patterns to avoid: Vendors who are vague about documentation timelines or who ask you to sign blank forms. Also watch for vendors who want full payment before DISCOM approval is secured.
Success indicator: The vendor provides a clear, written timeline showing each documentation step and the expected DISCOM response window.
Step 4: Evaluate Pricing Within the Subsidy Context
Objective: Understand the real cost of your system after subsidy, and identify pricing red flags.
A 3 kW system in Bihar typically costs â¹2.10 lakh to â¹2.40 lakh before subsidy, with an estimated net cost of â¹1.20 lakh to â¹1.32 lakh after the â¹78,000 central subsidy. If a vendor quotes significantly below this range, ask what's being cut. If they quote significantly above it, ask what's being added.
The critical pricing question is not "how cheap can you go?" but "what is included in this price that protects my subsidy eligibility?" A vendor who uses non-BIS-certified panels or uncertified inverters may save you â¹15,000 upfront but will cause your installation to fail the DISCOM inspection. For a detailed breakdown of what actually drives costs, see this real solar panel cost breakdown.
Anti-patterns to avoid: Choosing the cheapest quote without verifying equipment certifications. Also avoid vendors who bundle the subsidy amount into their quote as a "discount" rather than explaining it as a separate government disbursement to your bank account.
Success indicator: You have a written quote that separates equipment cost, installation cost, and expected subsidy amount, with BIS certification details for all major components.
Step 5: Check Track Record on Subsidy Disbursement
Objective: Verify that the vendor has a history of completed installations where the subsidy was actually disbursed.
Empanelment alone doesn't guarantee competence. Ask the vendor for references from past Bihar customers who have received their subsidy. Not customers who are "waiting for it" or whose "application is in process," but customers who have the money in their bank account. A vendor who has been empanelled for months but cannot point to a single completed subsidy disbursement is either new (which carries risk) or ineffective at navigating the process.
If possible, call one or two references directly. Ask them: How long did the process take from application to subsidy receipt? Did the vendor handle the DISCOM inspection coordination? Were there any delays, and how did the vendor respond? The BREDA channel is the state-level facilitator, and a good vendor will have a working relationship with this agency.
Companies like Ghar Ghar Solar, which operate specifically in Bihar with a local presence, can often provide verifiable references from nearby neighborhoods, making this step easier for homeowners who want to speak with someone in their own area.
Anti-patterns to avoid: Accepting testimonials on the vendor's website as proof. Also avoid vendors who refuse to share customer references citing "privacy" without offering any alternative verification.
Success indicator: You have spoken with at least one past customer who confirms subsidy receipt, and the timeline they describe is consistent with what the vendor promised you.
Step 6: Secure Written Commitments on Subsidy Facilitation
Objective: Get contractual clarity on what happens if the subsidy application fails or is delayed due to vendor error.
Before you pay anything, your agreement with the vendor should include explicit clauses covering: the vendor's responsibility to submit all portal applications, the vendor's commitment to coordinate with the DISCOM for feasibility approval and post-installation inspection, a timeline for net metering commissioning, and a clear statement of what happens if the subsidy is denied due to vendor-side errors (incorrect documentation, non-compliant equipment, missed deadlines).
This is not about being adversarial. It is about aligning incentives. A vendor who is confident in their process will have no problem putting these commitments in writing. A vendor who resists written commitments is telling you something important about their confidence in their own empanelment and process.
Anti-patterns to avoid: Verbal assurances like "don't worry, we handle everything." Also avoid contracts that make the subsidy the homeowner's sole responsibility after installation is complete.
Success indicator: You have a signed agreement that explicitly names the vendor's subsidy-related responsibilities and includes a remedy clause for vendor-caused delays or rejections.
Step 7: Understand the Post-Installation Verification Sequence
Objective: Know exactly what happens after panels go on your roof, so you can hold the vendor accountable through the final mile.
Installation is not the finish line. After installation, the vendor must upload commissioning details and photographs to the national portal. The DISCOM then sends an inspection team to verify the installation. Only after the DISCOM inspection is cleared and the net meter is commissioned does the subsidy disbursement process begin. Bihar's policy provides 100% banking of energy across all 12 months, which means your net meter setup directly affects your long-term savings.
Many scam scenarios exploit this gap. The installer finishes the physical work, collects payment, and disappears before the portal submission and DISCOM inspection. You're left with panels on your roof but no subsidy and no net metering. A legitimate vendor stays engaged through this entire sequence.
Anti-patterns to avoid: Paying the final installment before the DISCOM inspection is completed. Also avoid assuming that because the panels are generating power, the subsidy process is on track.
Success indicator: You can log into the national portal and see your installation's commissioning report uploaded, and you have a confirmed date for the DISCOM inspection.
Practical Examples: What Goes Right and What Goes Wrong
Scenario A: The Shortcut That Costs â¹78,000
A homeowner in Muzaffarpur finds an installer offering a 3 kW system for â¹1.85 lakh, well below market rate. The installer says the subsidy will be "adjusted" in the price. The homeowner pays in full. Panels go up in two weeks. But when the homeowner checks the national portal, there is no application. The installer, it turns out, was not empanelled under NBPDCL. The homeowner now has a working solar system but no path to the â¹78,000 subsidy and no net metering. The system generates power, but excess energy is wasted because there is no net meter to credit it.
Scenario B: The Patient Process That Pays Off
A homeowner in Patna verifies the installer's empanelment on the portal, confirms SBPDCL authorization, and signs a contract with subsidy facilitation clauses. The installer submits the application, waits for DISCOM feasibility approval (which takes three weeks), then begins installation. After installation, the vendor uploads commissioning data, coordinates the DISCOM inspection, and the net meter is installed within six weeks. The subsidy of â¹78,000 is disbursed to the homeowner's bank account two months later. Total time from first contact to subsidy receipt: approximately four months. Total out-of-pocket cost after subsidy: â¹1.25 lakh.
What Separates These Two Outcomes
The difference is not panel quality or price. It is whether the vendor was empanelled, whether the correct sequence was followed, and whether the homeowner verified before paying. Scenario B took longer, but the homeowner saved â¹78,000 and has a net-metered system that earns credits every month. Ghar Ghar Solar's approach in Bihar follows this second model: verify first, install in sequence, and stay accountable through subsidy disbursement.
Common Mistakes and Pitfalls
Paying in full before DISCOM approval: This removes the vendor's incentive to complete the subsidy process. Structure payments in milestones tied to DISCOM approval, installation, inspection, and net metering.
Confusing a sales office with empanelment: A vendor can have a physical office in your city without being empanelled. Office presence is not the same as portal registration.
Ignoring the DISCOM-vendor mismatch: Empanelment under NBPDCL does not cover SBPDCL areas. Always match your bill to the vendor's registration.
Treating the subsidy as guaranteed: The subsidy depends on a chain of correct actions. Any documentation error, equipment non-compliance, or process shortcut can break the chain. Treat it as conditional until the money is in your account.
Skipping reference checks: It takes 15 minutes to call a past customer. It takes months to recover from a failed subsidy application. The math is clear.
These mistakes are not signs of carelessness. The system is complex, and information is scattered. The point is not to blame yourself if you've made one of these errors, but to know what to watch for going forward.
What to Do Next
Start with one action: go to the national portal's vendor list, select Bihar, select your DISCOM, and see which vendors are listed. Save or screenshot the results. This gives you a verified shortlist before you talk to anyone.
From there, use this guide as a reference checklist, not a one-time read. Each step corresponds to a specific conversation you'll have with a potential vendor. Bring the questions from each step to those conversations. If a vendor can answer them clearly and confidently, you're likely in good hands. If they deflect, rush, or get vague, move to the next name on your list.
Your subsidy eligibility is not something to figure out after installation. It is the first decision you make, and the vendor you choose is how you make it.
Frequently Asked Questions
What are the steps involved in applying for solar subsidies under PM Surya Ghar Yojna?
The process follows a specific sequence: register on the national solar rooftop portal, select an empanelled vendor, get DISCOM technical feasibility approval, complete installation, have the vendor upload commissioning details, pass the DISCOM inspection, get your net meter commissioned, and then the subsidy is disbursed to your bank account. Skipping or reordering these steps can invalidate your application.
Why is it important to get DISCOM approval before installing solar panels?
DISCOM feasibility approval confirms that your electrical connection and roof can support the proposed system, and it formally registers your application in the subsidy pipeline. If you install before getting this approval, the DISCOM has no record of your project, and your vendor cannot upload commissioning data to the portal. This effectively locks you out of the subsidy.
How do I ensure my solar installation qualifies for government incentives for solar?
Three things must be true: your vendor must be empanelled under your specific DISCOM (NBPDCL or SBPDCL in Bihar), all equipment must carry BIS certification, and the correct application sequence must be followed through the national portal. Verify all three before signing any agreement.
Which documents are required for the solar subsidy application process?
You will typically need your Aadhaar card, a recent electricity bill from your DISCOM, bank account details (for subsidy disbursement), proof of roof ownership or authorization, and passport-size photographs. Your empanelled vendor should provide a complete checklist specific to your DISCOM's requirements and handle the portal submission on your behalf.
When can I expect to receive the subsidy amount after installing solar panels?
In Bihar, the timeline from completed installation to subsidy disbursement typically ranges from 6 to 12 weeks, depending on DISCOM inspection scheduling and portal processing. However, delays are common if documentation is incomplete or if the vendor fails to upload commissioning data promptly. Having a written timeline commitment from your vendor helps set realistic expectations.
How can I verify if a solar installer is genuinely empanelled in Bihar?
Visit the national solar rooftop portal's statewise vendor list, select Bihar, and choose your DISCOM (NBPDCL or SBPDCL). Search for the vendor's company name. If they appear with a registration number, they are empanelled. Do not rely on the vendor's own claims, screenshots, or certificates. The portal is publicly accessible and takes less than two minutes to check.
