PMKUSUM Component B: Solar Pump Subsidy Guide for Installers

If you only sell rooftop solar, you are ignoring one of the largest government-funded order books in Indian solar. Under PM KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyaan), the PMKUSUM Component B solar pump programme pays for standalone off-grid solar water pumps for farmers, and the government funds up to 60% of every system you install. More than 3 crore diesel pumps still run on Indian farms, according to the Ministry of New and Renewable Energy (MNRE), and replacing them is a national priority.

This guide is written for EPCs and installers, not farmers. It covers the subsidy structure, who qualifies, how empanelment works, the application workflow, pump sizing and pricing, documentation, the rejection reasons that kill projects, and how to quote PMKUSUM-B work profitably.

What PMKUSUM Component B Actually Covers

PM KUSUM has three components, and confusing them is the first mistake new installers make. Component A covers small ground-mounted solar plants (500 kW to 2 MW) on farmland. Component B covers standalone solar agricultural pumps, fully off-grid systems that replace diesel or kerosene pump sets where no grid connection exists. Component C covers solarisation of existing grid-connected agricultural pumps.

Component B is the volume play. MNRE's target is roughly 17.5 lakh standalone pumps nationally under the scheme, according to MNRE scheme documentation (2019, revised targets), with state-wise tender awards under the component tracked each quarter by Mercom India. Pumps range from 2 HP to 7.5 HP for standard applicants, with 10 HP allowed in some states for deep borewells. Every system includes modules, mounting structure, pump motor, controller with remote monitoring, and a mandatory 5-year comprehensive warranty.

The Subsidy Structure: Central, State, and Farmer Share

The subsidy is calculated on the MNRE benchmark cost for each pump capacity, not on your invoice price. Per a Press Information Bureau release (2023), Central Financial Assistance (CFA) is 30% of the MNRE benchmark cost or the tender-discovered price, whichever is lower. The standard split:

Two details matter for your quote. First, the PIB release (2023) confirms Components B and individual pump solarisation under C can run even where a state does not commit its 30% share, in which case the farmer's contribution rises. Second, CFA is released to you (the vendor) through the state nodal agency after commissioning and inspection, so your working capital planning must absorb a 60 to 120 day receivable cycle in most states.

Who Is Eligible: The Farmer and the Field

Eligibility is farmer-side, but you will be the one screening it in practice. A qualifying applicant is an Indian farmer with agricultural land (owned, or leased with a registered tenancy agreement), a working water source on or near the field, and critically, no existing grid-connected pump connection on that survey number. The Aadhaar-linked bank account is mandatory because any farmer-side subsidy flows via DBT.

Priority goes to small and marginal farmers (landholding up to 2 hectares) and SC/ST applicants. In states where applications exceed the annual allocation, priority categories clear the queue first. A farmer with an existing electric pump on the same field belongs in Component C, and pushing them into Component B is one of the most common rejection triggers.

Empanelment: How to Become an Approved Component B Vendor

You cannot install a subsidised Component B pump unless your firm is empanelled with the state nodal agency. Unlike PM Surya Ghar, where DISCOM empanelment is relatively open, PMKUSUM-B vendor selection usually runs through competitive tenders or expression-of-interest rounds at the state level: GEDA in Gujarat, RRECL in Rajasthan, MAHAURJA in Maharashtra, UPNEDA in Uttar Pradesh, MPUVNL in Madhya Pradesh, HAREDA in Haryana.

1. 1

   Get your compliance file ready

   GST registration, PAN, Udyam registration, 2 to 3 years of ITRs and financials, and a solvency certificate. Most tenders also ask for an EMD (earnest money deposit), typically 1 to 2% of the bid value.

2. 2

   Lock compliant hardware

   Modules must be on the ALMM list, and pump sets must meet MNRE specifications and BIS standards. Our explainer on the ALMM list and what it means for your procurement covers the module side in detail.

3. 3

   Bid in the state tender or EOI round

   You quote a per-HP rate against the MNRE benchmark ceiling. L1-style price discovery is common, so know your breakeven before you bid, including the 5-year warranty and service cost.

4. 4

   Sign the rate contract and build a service network

   Most agencies require district-level service presence or a declared service partner. The 5-year comprehensive warranty is enforced, so budget one to two service visits per pump per year.

The Application Workflow, Step by Step

The farmer applies, but in practice the empanelled vendor drives the file. The national portal is pmkusum.mnre.gov.in, while most states route applications through their own nodal agency portals.

1. Screen and register the farmer. Verify land record, water source, and no existing grid connection. Register on the state portal (geda.gujarat.gov.in, rrecl.com, upneda.org.in, mahaurja.com) with the farmer's Aadhaar-linked mobile number.
2. Submit the application with documents. Land records, Aadhaar, bank details, water source proof. See the documentation section below.
3. Wait for selection and the demand letter. Batch-wise review takes 15 to 30 days in Gujarat, 30 to 60 days in most other states, per nodal agency processing norms reported in 2025 to 2026.
4. Collect the farmer's contribution. The demand letter opens a window (usually around 30 days) to deposit the 10% share. Farmers who miss the window lose the slot.
5. Install and commission. A standard 5 HP system takes 3 to 5 days on site. The state inspector then certifies the installation, typically within 7 to 15 days.
6. Claim the subsidy. CFA plus state share releases to your account after the commissioning certificate, subject to fund availability in that state's allocation.

Pump Sizing and Pricing: The Benchmark Math

Sizing is governed by MNRE guidelines: 2 to 3 HP for holdings up to about 2 acres with shallow wells, 5 HP for 2 to 5 acres, 7.5 HP for larger holdings or medium-depth borewells, and 10 HP in states that allow it for deep borewells. The nodal agency's field officer confirms the approved HP during site verification, so never pre-sell a 7.5 HP system before that check.

MNRE publishes benchmark costs per HP, and the subsidy applies to that benchmark. The table below uses indicative benchmark ranges reported by industry trackers in 2025; always pull the current benchmark from MNRE before quoting.

If your tender rate exceeds the benchmark, the farmer pays the difference, and that difference is where deals die. Keep your per-HP rate at or under benchmark, and make margin on volume and efficient installation instead. For broader pricing context across system types, see our data on solar system pricing by state.

Documentation: What the File Must Contain

Rejections at the documentation stage are avoidable and embarrassingly common. The complete file for a Component B application:

• Aadhaar card of the applicant, matching the bank account for DBT.
• Land record in the state format: 7/12 Utara and 8A in Gujarat, Jamabandi in Rajasthan, Khasra or Khatoni in MP and UP.
• Bank passbook or cancelled cheque of an Aadhaar-seeded account.
• Water source proof: borewell completion report or groundwater permission where required.
• Tenancy agreement plus landowner consent, for tenant farmers.
• Recent passport-size photograph.

GST treatment on your invoice is separate from the subsidy file. Solar pump supply-and-install is generally billed as a composite supply; our breakdown of GST on solar installation services covers how to structure it.

Common Rejection Reasons and How to Prevent Them

Most Component B files fail for administrative, not technical, reasons. Ranked by frequency in nodal agency feedback and installer reports through 2025:

1. Name mismatch between Aadhaar and the land record. The top rejection. Fix it at the Talati or Tehsildar office before applying.
2. Existing grid connection on the same survey number. Makes the farmer ineligible for Component B; redirect to Component C.
3. Stale land records. Outside the 6 to 12 month freshness window some states enforce.
4. Bank account not Aadhaar-seeded. DBT fails silently and the file stalls.
5. Unverified water source. Missing borewell completion report or groundwater permission.
6. State quota exhausted. MNRE allocates state-wise annual targets; late-year applications get waitlisted. File early in the financial year.

One more worth stating plainly: the government application is free. Agents charging "application fees" or "guaranteed selection" fees before the demand letter are a fraud risk that damages the whole vendor ecosystem. Tell your farmers this explicitly.

Component B vs Component C vs PM Surya Ghar: Where to Focus

Each scheme serves a different customer and a different margin profile. Choose based on your working capital, service network, and district mix.

Compared with PM Surya Ghar rooftop work (our PM Surya Ghar subsidy slabs guide covers that side), Component B has less sales friction but thinner margins and heavier after-sales obligations. Component C sits between the two: grid-connected farmers, DISCOM involvement, but an existing customer base you can identify from agricultural feeder data. For the wider policy picture, our roundup of MNRE guidelines for 2026 tracks what changed across schemes.

How to Quote PMKUSUM-B Projects Profitably

The installers who lose money on Component B all make the same error: they quote like it is a rooftop job with a subsidy discount. It is not. We call the correct method the KUSUM-B Bid-to-Bank Stack: price against the benchmark, not the customer; fund the receivable, not just the install; and sell the warranty tail, not just the pump.

In practice, the stack means four things on every quote. Show the benchmark price, the exact subsidy split, the farmer's 10% and loan option, and the diesel saving payback, all on one page. Add your cost structure on top: module, pump set, structure, transport to a rural site, installation crew, two warranty visits a year, and the financing cost of a 90-day subsidy receivable. If that full stack still clears your margin floor at the tender-discovered rate, bid. If it does not, skip that state and put the capital into rooftop instead. Our solar installation cost breakdown is a good base for building the line-item model, and the QuickEstimate pricing page shows what it costs to run the quoting side digitally.

The exception worth admitting: in states where the discovered rate is very close to benchmark and the agency pays within 45 days (Gujarat and Rajasthan have the better reputations here, per installer reports in 2025), Component B volume can outperform residential rooftop on a pure margin-per-crew-day basis.

How QuickEstimate Fits

PMKUSUM-B sales are high-volume and documentation-heavy. Your field team is collecting land records, Aadhaar copies, and water-source photos at farm gates, then chasing demand letters and farmer contributions over WhatsApp for weeks. That workflow collapses if it lives in a notebook and a personal WhatsApp account.

• Proposal Generator, produce a branded one-page quote showing benchmark cost, the 30% + 30% subsidy split, farmer share, and diesel payback in under a minute from the field.
• WhatsApp Follow-up, nudge farmers on the demand-letter window and the 10% deposit, with read receipts so you know who has seen the reminder.
• Quotation System, keep per-HP rates and state-wise subsidy math consistent across every sales rep, so no one quotes off a stale benchmark.
• Pipeline Management, track each file by stage (applied, demand letter, deposit paid, installed, commissioned, subsidy received) instead of losing files between site visits.

If you are building the farmer-lead side of this business, our guide on how to manage solar leads at volume covers the intake and follow-up structure that keeps a 100-file pipeline moving.

What to Do This Week, For Your EPC

1. Check your state's empanelment calendar. Visit your nodal agency's site (GEDA, RRECL, UPNEDA, MAHAURJA, or yours) and note the next tender or EOI window, the previous discovered rate, and the EMD amount. This takes 30 minutes.
2. Pull the current MNRE benchmark costs from mnre.gov.in and rebuild your per-HP rate card. If your numbers predate the last benchmark revision, your subsidy math is wrong in at least one direction.
3. Run the Bid-to-Bank Stack on ten past quotes. Add the receivable financing cost and two annual warranty visits to your old per-HP price. If the real margin survives at your state's discovered rate, bid the next round. If not, you just saved a working-capital mistake.

Frequently Asked Questions

What is PMKUSUM Component B?

PMKUSUM Component B is the part of the PM KUSUM scheme that funds standalone, off-grid solar water pumps for farmers, replacing diesel pump sets where no grid connection exists. It covers pumps up to 7.5 HP (10 HP in some states) with a subsidy of 30% central plus 30% state on the MNRE benchmark cost, per MNRE guidelines.

How much subsidy does a farmer get under Component B?

In general states, the farmer gets 60% of the benchmark cost as subsidy (30% central CFA plus 30% state share), pays 10% upfront, and can finance another 30% through a concessional bank loan. In northeastern and hilly states, the central share rises to 50%, taking total subsidy to 80%, per MNRE scheme terms.

Who is eligible for a PMKUSUM Component B pump?

An Indian farmer with owned or leased agricultural land, a working water source (borewell, open well, or canal intake), and no existing grid-connected pump connection on that survey number. Small and marginal farmers and SC/ST applicants get priority in oversubscribed states, according to MNRE guidelines.

How does an installer get empanelled for PMKUSUM Component B?

Through the state nodal agency (GEDA in Gujarat, RRECL in Rajasthan, UPNEDA in UP, MAHAURJA in Maharashtra), usually via a competitive tender or expression-of-interest round. You need GST and Udyam registration, financials, an EMD, ALMM-listed modules, MNRE-spec pump sets, and a district-level service network, per state tender conditions.

How long does a Component B project take end to end?

A clean file takes roughly 45 to 90 days from application to commissioning: 15 to 60 days for selection and the demand letter, around 30 days for the farmer's deposit, 3 to 5 days for installation, and 7 to 15 days for inspection. Subsidy disbursement to the vendor can take another 60 to 120 days depending on the state.

What is the most common reason Component B applications get rejected?

A name mismatch between the applicant's Aadhaar and the land record is the most frequent rejection, followed by an existing grid connection on the same survey number, stale land records, and non-Aadhaar-seeded bank accounts. All four are preventable with a 30-minute pre-check before filing.

Is PMKUSUM Component B profitable for installers?

Yes at volume, if you price against the state tender-discovered rate rather than the MNRE benchmark ceiling and budget for the 5-year warranty plus a 60 to 120 day subsidy receivable. Margins per project are thinner than residential rooftop, but sales friction is far lower because 60% of the cost is government-funded.
