From feasibility, structural assessment and electrical design through CEIG, DISCOM and net-metering approvals to installation and commissioning — delivered by one accountable engineering team.
Design, approvals and execution under one contract — not three vendors and a coordination problem.
Industrial tariffs move in one direction. Solar is the only line in a factory's energy cost you can fix for twenty-five years, which is why it gets board attention that a lighting retrofit never does.
A module supplier, an electrical contractor and an approvals consultant means every interface is somebody else's problem. When generation underperforms, you get three explanations and no fix.
Metal sheet roofs vary enormously in purlin spacing and residual capacity. A capacity quoted before the structural check is a guess, and correcting it after procurement is expensive.
Net metering and CEIG are frequently excluded from the quote in a line nobody reads. The plant then sits commissioned but unsynchronised while the paperwork is sorted out.
Three inputs. Your numbers appear before we ask for anything.
Indicative only — not a quotation. Actual output depends on shading, tilt, tariff structure and DISCOM policy. Open the full model for payback, IRR and NPV.
Equipment recommendations, a shadow-aware layout, DISCOM route for your state, and the full financial model — prepared by an engineer, not generated.
An engineer will send your feasibility report within one business day.
We are not the lowest number you will be shown, and this is where the difference sits. Every item below is something we have been called in to correct on somebody else's installation.
Capacity sized to the roof, not the load
A bigger number reads better on a quote. But generation you cannot consume — and cannot export under your net-metering cap — earns nothing. Sizing follows your consumption pattern and sanctioned load, or it is decoration.
Structure priced for a flat roof
Mounting on an industrial shed carries wind and dead load into a structure that was designed for neither. The cheap quote assumes standard purlins and discovers otherwise on site.
Approvals excluded in a footnote
Read what the quote actually includes. Net metering, CEIG and DISCOM liaison are real work with real timelines, and if they are not in the scope they become yours.
No shading study
Chimneys, water tanks, adjacent blocks and inter-row spacing all cost generation. A yield figure produced without a shading analysis is arithmetic, not engineering.
Electrical integration treated as an afterthought
Solar has to land in an existing LT or HT system alongside DG, and the protection scheme has to work for both. This is where solar-only installers run out of depth — and where an MEPF contractor is doing familiar work.
Electricity bill and load analysis
We start from twelve months of bills, your sanctioned load and your shift pattern — not a per-sq-ft rule of thumb. This decides capacity before anything else is discussed.
Site survey, structural and shading assessment
Roof condition, purlin spacing and residual capacity; obstructions and inter-row shading. This is what turns an indicative number into an engineered one.
Feasibility and financial model
Capacity, generation estimate, CAPEX versus OPEX comparison and payback — with the assumptions stated so your CFO can challenge them.
Design and electrical integration
Array layout, string design, inverter selection, LT/HT integration, protection scheme and DG coordination.
Approvals — filed by us
Net-metering application, DISCOM technical feasibility, CEIG approval. In-house, because approvals are our core trade.
Supply, installation and testing
Procurement against specification, mounting, DC and AC works, earthing and lightning protection, then testing.
Synchronisation and commissioning
Bi-directional meter, DISCOM synchronisation, performance verification and handover documentation.
Monitoring, O&M and AMC
Generation monitoring and preventive maintenance — because a plant that silently underperforms for three years costs more than it saved.
The engineering is identical in all three. What changes is who puts up the capital, who owns the asset, who carries the O&M, and who keeps the savings.
You fund it, you own the asset, and every rupee it saves stays with you.
Trade-off: You fund the capital and carry the O&M.
Compare on lifetime rupeesA lender funds the bulk of the plant against a contribution from you. You still own the asset at the end.
Trade-off: You take on a repayment obligation and the O&M, and the lender takes security over the building.
Test it against your own EMIAn investor or developer builds and owns the plant on your roof, and you buy the units it makes. This is how the model works in the market — whether a given project qualifies is a question for assessment, not a standing SEPL offer.
Trade-off: Smaller saving, usually more total cost than owning across 25 years, and you give a third party rights over your roof for the term.
Model a PPA offer you've been sentSolar PPA, RESCO or bank loan — which suits your factory?
Request a project-specific review of bank-financed ownership and investor-funded alternatives. Availability, borrower contribution and terms depend on project assessment and the lender or investor.
Published borrower contribution on the captive solar schemes we checked (2026-09-27): State Bank of India Surya Shakti Solar Finance — 20% minimum for captive projects, with deviation not permitted; 25% minimum for other-than-captive; Indian Bank IND-SURYA SHAKTI — 25% on the cost of the equipment and erection charges. SEPL is an EPC contractor, not a lender — we are not presented here as a partner of any bank, and the loan decision is the lender's.
Want to see what a real proposal looks like before you talk to anyone?
We'll send a worked 500 kWp commercial example — layout, BOQ structure, generation model and the full CAPEX-versus-PPA comparison. A sample, not a quote for your site.
Figures above are indicative and depend on your tariff, region, roof and tax position. Tax treatment changes — confirm depreciation and input-credit specifics with your CA before you commit. We put the assumptions on screen rather than in a footnote.
DISCOM Net-Metering & CEIG Applications Prepared and Filed In-House.
Approvals are our core trade as an MEPF contractor — not something we sub out to a consultant and hope for. You sign, we file, we follow up.
Feasibility & application
Load study, single-line diagram and the net-metering application prepared and filed.
CEIG / Electrical Inspector
Drawings, test reports and the inspection itself — coordinated and attended by our team.
Synchronisation & meter
Bi-directional meter, DISCOM sign-off and grid synchronisation, through to commissioning.
Calculators, costed examples, state guides and the approval route — open, ungated, and written by the team that does the work.
The engineering is the same; what changes is the roof, the load pattern and the approvals that apply.
Worked examples at four capacities. Indicative — your tariff, roof and region move the numbers.
Every one gives a usable answer without a form. The assumptions are shown on screen, not buried in a footnote.
The part most quotes leave out. Which DISCOM grants net metering, which Inspectorate approves the install, and in what order.
Where we execute, and what is specific to each state's supply and approvals.
What solar changes is different in each. These are the sector pages, with the solar angle called out.
Verified projects only — capacity and outcome figures appear where the project record carries them.
Planning something similar? Request a feasibility review.
We are vendor-neutral and buy on bankability, warranty terms and service reach — not on whoever is discounting hardest this quarter. Final makes are fixed in your BOQ and agreed before order.
Listed makes are those we specify and procure against. Names and marks belong to their respective owners; listing them indicates the equipment we install, not endorsement or an exclusive partnership.
Two steps. The first asks nothing personal — just enough about your facility for an engineer to tell you whether solar stacks up, and at what size.
Usually within one business day. If it's urgent, call +91 70099 85817 or message us on WhatsApp.
It follows your consumption, not your roof. We size against twelve months of bills, your sanctioned load and your daytime demand curve, then check the roof can carry it. Capacity you cannot consume or export earns nothing, so a bigger number on a quote is not automatically better. The calculators on this page give an indicative figure in a minute; a site survey turns it into an engineered one.
Yes, in-house. Approvals are our core trade as an MEPF contractor — we file Fire NOC and CEIG applications routinely, and net metering runs through the same team. We publish state-by-state guides to the process so you can see what is involved before you commit.
It is a finance question, not a solar one — the engineering is identical. CAPEX means you fund it, own the asset, keep 100% of the saving and claim accelerated depreciation. OPEX/PPA means a developer funds it and you buy the units, with no capital outlay but a smaller saving and usually more total cost over 25 years. The comparison calculator models both against your actual tariff.
Engineering and installation are usually the predictable part. Approvals are what move the date, and they vary by state and by how complete the application is when it is filed. We prepare approvals in parallel with procurement rather than after execution, specifically so inspection is not what holds up synchronisation.
We tell you before you commit, and we say so in the feasibility rather than after procurement. Sometimes the answer is a smaller array, sometimes structural strengthening, sometimes a ground-mount or carport instead. What we will not do is quote a capacity the structure cannot carry.
We have delivered projects across 18+ Indian states. The seven states with dedicated pages are the ones where we file approvals routinely and know the DISCOM process in detail. For anywhere else, ask — the engineering travels, and the approvals are learnable, but we would rather be straight with you about the difference.
It settles tariff, sanctioned load and consumption in one photo — three of the four inputs any real assessment needs. An engineer will come back with an indicative size, saving and payback.
