Operations & Maintenance
Performance monitoring, preventive maintenance and uptime-backed contracts. Live plant data flows straight into the investor portal your team already uses.
See live dataAdvisory & Quotations
Transparent per-kW costing, GST-inclusive quotes and honest payback modelling — so your finance head signs off as fast as your plant manager does.

Why Imperra
Built by manufacturers,
not by contractors
Most solar developers come from construction. We came from running factories — where an hour of downtime is a number on a P&L, not a line in a report.
01
Industrial-grade engineering
Structural loading, cable sizing and earthing designed to plant standards — not to the minimum the inspection asks for.
02
Schedules we actually hold
Procurement locked before mobilisation. Milestone dates go in the contract because we intend to hit them.
03
We own what we build
A large share of our 83.25 MW is on our own balance sheet. We live with the design decisions for 25 years, same as you.
04
Data you can audit
Daily generation, per-MW yield and variance against expected — visible to you in the portal, not summarised in a monthly PDF.
05
Gujarat is home ground
Surat-based, working across six districts. DISCOM paperwork, land records and local vendors are relationships, not obstacles.
06
One accountable team
The engineer who sized your array is reachable when the inverter throws a fault three years later. No subcontractor maze.
Environmental impact

In their words
What our clients say
“
They sized the array against our actual shift pattern rather than our sanctioned load, and the first year's generation came in where they said it would. That is not something we had experienced before.

“
The O&M team flags a dip before we notice it on the bill. Having the daily numbers in one dashboard has made the whole thing auditable for our finance department.

Quote to commissioning ran to the schedule they gave us at signing. For a rooftop of this size in Gujarat, that alone was worth the decision.

Our foundation
Engineering rigour.
Disciplined execution.
We develop, build and operate utility-scale solar power infrastructure — bringing manufacturing-grade discipline to India's clean energy transition.
Leadership
The people behind Imperra
Dhiraj Rathi
Managing Director
Two decades of heavy-industry and manufacturing leadership within Eagle Group. Dhiraj drives strategic land acquisition, regulatory alignment and the operational discipline that lets utility-scale solar scale without quality drifting.
Manish Jaju
Managing Director
Manish leads Imperra Energy alongside Dhiraj, with responsibility for the group's growth in renewables — project development, capital deployment and the partnerships that take the portfolio beyond its current 83.25 MW.
Heritage
Built on Eagle Group's
industrial foundation.
Imperra Energy stands on the foundation of Eagle Group — a Surat conglomerate synonymous with strength, consistency and performance across core industrial sectors.
That heritage brings a deep understanding of large-scale project execution, rigorous quality control and long-term asset value — principles we apply directly to the renewable portfolio.
Philosophy
Manufacturing precision,
applied to solar.
We reject the standard approach to solar deployment. Every site is treated not as a construction project but as an engineered power generation facility.
Rigorous site engineering before ground is broken
Quality control at every construction milestone
Long-term asset value over short-term completion
Track record
How the portfolio grew
From the first captive rooftop to a state-wide generating base.
Gen 1
Eagle Group established in Surat — textile and yarn manufacturing across three generations.
Phase I
First captive rooftop plants commissioned for group textile units.
Phase II
Expansion into ground-mount clusters across Bharuch, Narmada and Vadodara.
Phase III
Kutch and Banaskantha sites added; O&M practice formalised.
Today
83.25 MW DC across 11 sites and 29+ plants, with live investor reporting.
Standards & compliance
How we hold the line
Every plant is engineered, documented and handed over against a fixed standard — the same one whether it is our asset or yours.
Tier-1 modules only
BIS-listed, ALMM-compliant modules with full manufacturer warranty pass-through.
Documented handover
As-built drawings, string test reports, torque logs and O&M manual with every commissioning.
DISCOM & net-metering
Application, inspection and approval handled end to end with the relevant Gujarat DISCOM.
Safety on site
Height, electrical and hot-work protocols enforced for our crews and every subcontractor.
Careers
Engineers who want
their name on the plant.
We hire slowly and keep people long. If you are a site engineer, a design engineer or an O&M technician who would rather own an asset than close a ticket, we should talk.

Whether you're a manufacturer exploring solar or an investor evaluating the sector, we'd like to hear from you.
What we do
Four services.
One accountable team.
From the first shadow analysis to the twenty-fifth year of generation reports — engineered, built and operated by the same bench.
Solar EPC
Design · Build · Energise
Turnkey ground-mount and rooftop solar. We survey, engineer, procure, construct and commission — one contract, one schedule, one point of accountability.
- Shadow analysis, structural loading and string layout
- ALMM-compliant module and inverter procurement
- Civil, mounting, DC/AC and earthing execution
- String testing, DISCOM inspection and commissioning
Operations & Maintenance
Monitor · Maintain · Report
Uptime is the product. Scheduled cleaning, preventive maintenance, fault response and a generation record your finance team can audit line by line.
- Daily generation logging against expected yield
- Module cleaning cycles tuned to local soiling
- Inverter, cabling and hotspot thermography checks
- Live dashboard access for owners and investors
Advisory & Feasibility
Model · Cost · Justify
Before anyone signs anything: what the site can carry, what it will generate, what it costs and when it pays back — with the assumptions written down.
- Load-curve study against your actual consumption
- Transparent per-kW, GST-inclusive costing
- Payback, IRR and 25-year cashflow modelling
- Net-metering, open-access and captive structuring
Asset Development & Ownership
Acquire · Develop · Hold
We develop and hold generating assets ourselves. Land identification, approvals, evacuation and long-term operation — the same discipline whether the asset is ours or a partner's.
- Site identification and land due diligence
- Statutory approvals and evacuation planning
- Co-investment and partnership structures
- Lifetime asset management and reporting
How we work
From first call to first unit
A typical industrial rooftop runs 8–14 weeks from signed order to energisation. Here is what happens in between.
01
Enquiry & load study
You send twelve months of bills and the roof or land you have. We work out your real consumption pattern — not the sanctioned load — and what fraction solar can sensibly cover.
02
Site survey & engineering
Physical survey, shadow analysis, structural assessment and string layout. You get a system size, a generation estimate and the assumptions behind both.
03
Proposal & commercials
Per-kW pricing, GST breakup, payment milestones, payback and IRR. One document, no hidden scope, no "as applicable" line items.
04
Order, approvals & procurement
DISCOM application and net-metering paperwork filed in parallel with module and inverter procurement. Material is locked before we mobilise.
05
Construction
Civil and mounting, module installation, DC/AC cabling, earthing and LT panel work — with milestone QC sign-offs and torque logs recorded as we go.
06
Testing & energisation
String testing, insulation resistance, DISCOM inspection, meter change and grid synchronisation. Handover pack with as-builts and the O&M manual.
07
Operations & reporting
Cleaning cycles, preventive maintenance, fault response and daily generation logged against expected — visible to you in the portal from day one.
