Maharashtra Rooftop Solar for Businesses: Electricity-Duty Exemption, Policy Conditions and Records
A Maharashtra business should not treat rooftop solar approval as an electricity-duty exemption certificate. The connection arrangement determines how the installation operates with the grid. Duty treatment depends on the electricity-duty legislation, the applicable exemption instrument and the project's actual category and history.
AI Summary
A Maharashtra business should not treat rooftop solar approval as an electricity-duty exemption certificate. The connection arrangement determines how the installation operates with the grid. Duty treatment depends on the electricity-duty legislation, the applicable exemption instrument and the project's actual category and history.
This distinction matters especially in 2026. Maharashtra introduced a new renewable-energy and storage policy, followed by transition clarifications. Older policy benefits cannot simply be copied into every new rooftop proposal, and a ten-year benefit for qualifying captive Green Open Access projects is not a general ten-year exemption for all solar panels.
For an existing or proposed business installation, prepare one project chronology and one electricity reconciliation before calculating the exemption. This article explains that review as at 18 October 2026. It concerns commercial and industrial projects; household subsidy eligibility is a separate question.
Separate the three decisions
The project file should distinguish connection and safety permission, renewable-policy registration or eligibility, and electricity-duty treatment.
The distribution licensee deals with the installation's approved connectivity and energy-accounting arrangement. Maharashtra Energy Development Agency, commonly called MEDA or MahaUrja, administers relevant project-policy requirements. The electricity-duty authority deals with the duty legislation, registration, assessment and exemption conditions. Documents issued through these routes serve different purposes.
A net-metering acceptance confirms neither the beneficiary nor the duration of a tax concession. Equally, a policy registration does not excuse compliance with electrical safety standards or authorise a larger system than the approved connection allows. Identify which final documents the installer has actually delivered.
Maharashtra has several distribution licensees. A process used for an MSEDCL consumer is not automatically the upload workflow for a Mumbai consumer served by another licensee. Match the consumer account, project premises and permission documents to the correct service provider.
Start with the duty legislation
The Maharashtra Electricity Duty Act, 2016 expressly addresses energy produced through captive generation, renewable energy and other independent sources. Its classification is therefore broader than electricity purchased from the distribution company. Solar generation is not outside the Act merely because sunlight has no fuel invoice.
Section 4 permits notified exemptions, with conditions, area, purpose, limits and period as applicable. A business claiming relief must connect its consumption with the relevant exemption and eligibility evidence. A scheme presentation, installer quotation or projected payback chart cannot establish that connection.
The basic review distinguishes grid-purchased electricity, generation consumed by the business, electricity supplied to someone else and electricity exported to the licensee. Each category must be considered under the relevant provisions. Exemption of one stream does not automatically exempt every charge or every unit in the utility bill.
Do not confuse duty with transmission or wheeling charges, banking charges, grid-support charges, cross-subsidy surcharge or tax on electricity sales. Different legal instruments govern these amounts. A valid exemption from duty does not establish exemption from all network services.
Identify the policy by project history
The Maharashtra Renewable Energy and Energy Storage Policy 2025–26 to 2035–36 was approved through the Government Resolution of 18 March 2026. Its policy period extends to 31 March 2036. The policy preserves treatment under the 2015 and 2020 policies for projects already operational or under construction within its transition provision. It also preserves specified earlier arrangements, including the relevant off-grid part of the 2020 policy.
The September 2026 implementation clarification uses in-principle grid-connectivity approval before 1 April 2026 to identify projects continuing under the earlier policies. It also addresses projects that applied through MEDA's single-window route but were not yet registered: the prior connectivity approval matters. Protected older projects do not have an unrestricted option to choose the new policy instead.
Consequently, the panel purchase date and commissioning date alone may not decide the policy. Keep the application, MEDA project identification, connectivity approval and actual commissioning chronology together. Do not substitute a supplier's delivery challan for the relevant approval milestone.
Where a particular rooftop approval uses a distribution-level route different from the transmission-connectivity documents described in the transition clarification, obtain the appropriate agency's project-specific confirmation. Do not invent an equivalent date or classify a project simply because equipment was lying on the roof before April.
Understand what the ten-year statements actually cover
| Basis being considered | What must be established before claiming relief |
|---|---|
| 2015 renewable policy | The project falls within that policy and the applicable duty exemption; its solar provision concerns projects established under the policy for captive use |
| Project continuing under 2020 arrangements | The actual applicable policy provisions, amendments and duty instruments support the claim; older benefits cannot be imported by assumption |
| New policy captive Green Open Access relief | The long-term captive Green OA category, Maharashtra supply and qualifying energy storage requirements are met |
| Ordinary net-metered or behind-the-meter rooftop | Its own applicable exemption basis is identified; the existence of another project's ten-year concession is insufficient |
The 2015 policy contains a ten-year duty benefit for the solar projects established under that policy for captive use, alongside MEDA registration requirements. It also separately anticipates a policy for grid-connected rooftop projects. That context prevents a business from treating the isolated ten-year sentence as proof that every rooftop installation, of any vintage or ownership model, qualifies.
The 2020 solar provisions expressly retain applicable government taxes, cesses, fees and relevant distribution-company charges. Registration under that policy is not, by itself, a certificate of a blanket ten-year duty holiday.
Under paragraph 7.2.2 of the new policy, the ten-year duty incentive concerns long-term captive Green Open Access projects in Maharashtra supplying within Maharashtra and integrating storage for at least four hours at 50% of the contracted renewable capacity. The storage can be at the generation or consumer end under that provision. The ten years run from commissioning. This specific incentive must not be transferred to a small on-site rooftop installation merely because it includes a battery.
The storage conditions relevant to project connectivity are also distinct from the conditions for this duty benefit. Meeting a minimum connection requirement does not prove that the more specific incentive conditions have been met. Confirm the implementing instrument and authority acceptance before recognising the saving as established.
Map ownership and captive use correctly
Create a short ownership statement identifying the consumer, premises occupier, panel and inverter owner, project operator and party entitled to the electricity. Attach the lease, power-purchase agreement or financing agreement where relevant.
An owned installation bought under an engineering contract differs from a RESCO arrangement in which a developer owns the equipment and sells electricity to the premises occupier. A roof lease is not necessarily a lease of the generating plant. An equipment lease is not necessarily an electricity purchase. Read the contract's rights and obligations rather than accepting the invoice description.
If captive status is material, verify the applicable electricity-law ownership and consumption requirements and current rules separately. These requirements were amended in 2026; a historic checklist should not be reproduced without review. Common group ownership or a contract calling the supply “captive” does not, by itself, prove compliance.
Ask who bears duty if the intended exemption is denied, expires or ceases after an ownership change. A contractual allocation can decide reimbursement between the parties, but it does not bind the authority to grant an exemption. Budget both the supported case and the case in which duty becomes payable.
Assemble the exemption and compliance file
Keep the legal basis, project identity and continuing conditions in one accessible file. Useful evidence includes:
- Entity and authorised-signatory documents for the claimant.
- Premises ownership, occupation or roof-use rights.
- Project registration, approved capacity and relevant connectivity records.
- Commissioning certificate, meter installation records and opening readings.
- The exact exemption notification or order and any project-specific certificate.
- Ownership and captive-use evidence where the benefit depends on them.
- Storage capacity, duration, commissioning and operating evidence where required.
- Unit calculations, returns, payments and correspondence with the duty authority.
This is a preparation checklist, not a claim that every item is a mandatory upload for every project. The applicable provision and current service requirements decide the actual submission set.
The carried-forward electricity-duty rules provide a Form A registration route for specified non-licensee generation exclusively for own use. Under that own-use route, duty payable for a month is paid within ten days after month-end, and the quarterly Form B return is due by the fifteenth day of the following month. Establish how those requirements apply to the particular solar arrangement, exemption and current authority instructions. Supplies to other persons and other operating models should not be placed on the own-use form merely for convenience.
A policy exemption does not automatically remove every registration, declaration or reporting condition. The 2016 Act contains a specific treatment for energy exempt under section 3(2); do not assume that all notified policy exemptions have identical reporting consequences. Obtain the applicable filing position rather than stopping returns because the calculated payment is nil.
Reconcile generation, consumption, export and import
Use the approved meter arrangement to distinguish physical flows from financial settlement. In a simple installation without storage, if the generation meter records 30,000 units and the export meter records 8,000 units over the same period, 22,000 units remain for on-site consumption before any separately justified adjustment. If gross grid import is 12,000 units, the premises' physical consumption is approximately 34,000 units on those assumptions.
That does not mean the duty base is automatically 34,000, 22,000 or the 4,000-unit difference between import and export. The legally applicable category, exemption and approved billing method determine the duty treatment. A net credit on the bill must not erase the underlying flow records.
| Record | Why it matters |
|---|---|
| Generation meter | Establishes actual electricity produced within its measurement boundary |
| Import and export registers | Separate grid purchases from electricity injected into the network |
| Utility settlement statement | Explains credits, banking and billed quantities under the approved arrangement |
| On-site allocation | Supports the business consumption and any other-user supplies |
| Battery charging and discharge data | Prevents grid charging, solar charging and discharge from being counted incorrectly |
With batteries, simple generation-minus-export arithmetic may be inadequate. Explain charging sources, stored energy, discharge, losses and changes in stored balance. Do not count the same solar unit once when generated and again when discharged as two independently exempt units.
Maintain consistent meter dates and serial numbers. Keep replacement-meter closing and opening readings. Resolve discrepancies between an inverter dashboard, generation meter and utility statement before applying an exemption percentage or booking a recovery.
Review changes and the end of the benefit
Adding panels does not automatically restart an exemption. Create separate capacity and commissioning records for the addition, then establish whether it is a modification, a separately registered project or another category under the applicable policy and duty instrument.
The same review applies when the building is sold, the business changes its legal entity, a rooftop lease is assigned or a developer transfers the project. For projects governed by the relevant 2020 methodology, the February 2025 amendment adds no-dues requirements in the ownership-transfer process and addresses recovery of outstanding utility amounts. It is not a general extension of duty exemption.
Track the approved exemption end date and any continuing ownership, consumption or storage conditions. Review the financial effect before expiry rather than discovering the liability at the next audit. A certificate amendment recording a name change should not be treated as a new commissioning event.
When duty treatment is disputed, obtain the authority's written basis and review the relevant remedy and time limit promptly. Do not offset a disputed claim against other utility charges without an authorised adjustment. Maintain the undisputed billing and the disputed duty separately in the reconciliation.
assureOffice can support the accountant's related financial and practice work around a solar investment. The specialist project, metering and exemption evidence should accompany that work; there is no assumption that assureOffice grants technical approval or files electricity-duty applications.
A project review before claiming the saving
Before approving a solar-cost model or annual exemption schedule, answer five questions: which policy governs, which duty instrument applies, who qualifies, which units qualify and when the benefit ends. Link every answer to the project's actual documents.
If one answer remains unresolved, show its effect in the commercial analysis instead of assuming the most favourable outcome. Teams using assureoffice.in for related accounting work can keep the project reconciliation and unresolved items with their supporting financial records. The accountant's useful contribution is a traceable claim, a realistic cost estimate and timely escalation of a specific missing approval.
Frequently asked questions
1. Does net-metering approval itself establish duty exemption?
No. It establishes the approved connection and settlement arrangement. The business still needs the applicable electricity-duty exemption basis and any required eligibility or authority evidence for its project.
2. Is all self-consumed rooftop solar automatically exempt for ten years?
Do not assume so. Ten-year statements in the renewable policies have defined project categories and conditions. An ordinary rooftop installation must establish its own entitlement rather than borrowing an unrelated incentive.
3. Which policy applies if installation and commissioning occur in different years?
Read the transition provisions and actual approval history. For the 2026 transition, in-principle grid-connectivity approval before 1 April 2026 is significant. Equipment delivery and commissioning dates alone may not determine the policy.
4. Does an unprocessed MEDA application guarantee old-policy treatment?
No. The 2026 clarification distinguishes pending applications according to whether the relevant prior in-principle connectivity approval existed. Preserve the complete chronology and obtain confirmation for the project's particular approval route.
5. Can an older project choose whichever policy gives a better benefit?
Not freely. The transition clarification keeps protected projects under the applicable earlier policy and does not provide an unrestricted migration option. An addition must be analysed separately rather than relabelling the whole plant.
6. What is the new policy's specific ten-year duty incentive?
It concerns qualifying long-term captive Green Open Access projects supplying within Maharashtra, with storage meeting the four-hour and 50% contracted renewable-capacity conditions. It is not a universal rooftop concession.
7. Does installing a small backup battery satisfy that incentive?
Not necessarily. The qualifying category, storage capacity, duration and implementation requirements all matter. A battery described as “solar storage” does not prove the specific incentive conditions are met.
8. Are owned and RESCO rooftop systems treated identically?
They should not be assumed identical. Identify the generator, equipment owner, consumer and electricity-sale arrangement. The exemption's beneficiary and captive-use conditions may depend on those facts.
9. Does a roof lease establish ownership of the generating plant?
No. It normally concerns rights over the roof. Read the equipment, electricity-supply and financing contracts separately to establish ownership, operation and the party consuming or supplying electricity.
10. Can the power-purchase agreement guarantee an exemption?
A contract can allocate financial risk between parties, but it cannot require the duty authority to grant relief contrary to law. Include a clear allocation if the proposed exemption is denied or ends.
11. Which records distinguish exports from self-consumption?
Keep generation-meter and bidirectional import/export readings for aligned periods, together with the approved settlement statement. Explain meter boundaries and any separate supplies, auxiliary use or losses.
12. Is the utility's net billed quantity the physical consumption figure?
Not necessarily. Credits and banking can change the billed amount. Preserve gross import, gross export and generation separately, then apply the approved legal treatment to the relevant duty stream.
13. What changes when the project includes a battery?
Separate solar charging, grid charging, discharge, losses and stored-energy movements. Otherwise the same energy may be counted twice or grid electricity may be incorrectly treated as exempt solar generation.
14. Does duty exemption remove grid-support or banking charges?
No automatic conclusion follows. These charges arise under different regulatory provisions. Review each approved charge and any specific concession independently of the electricity-duty exemption.
15. Must an own-use generator consider duty registration and returns?
Yes. Establish the applicable registration and filing position with the duty authority. The own-use rules provide Form A registration and Form B reporting, while other arrangements require their own correct classification.
16. Does a nil payment mean no return is needed?
Not by itself. Check the exemption instrument, statutory provision and authority instructions. Payment relief and reporting relief are different questions, and one exemption category cannot automatically supply another category's reporting treatment.
17. Does adding panels restart the exemption clock?
No automatic restart follows. Document the addition's capacity, approval and commissioning date and establish whether it qualifies separately. The existing plant's expiry remains governed by its own legal basis.
18. What should be checked when ownership changes?
Review the transfer procedure, utility dues, beneficiary conditions, captive status and required amendments. Where the 2020 methodology applies, include its February 2025 ownership-transfer amendment in that review.
19. Does a proposed charge or draft regulation immediately change the position?
No. Establish the operative notification, regulation or order and its effective date. Policy proposals, committee reviews and consultation drafts must be distinguished from requirements actually brought into effect.
20. Can assureOffice approve the rooftop system or determine exemption?
Do not assume those specialist capabilities. assureOffice is relevant to surrounding financial and practice workflows. Technical permission, duty eligibility and statutory submissions require their own competent process and supporting evidence.
