Harnessing the Sun. Delivering Results. Building Trust.
India receives some of the highest solar irradiation levels in the world — making solar power not just an environmentally responsible choice, but one of the most financially compelling energy investments available to businesses, industries, and institutions today. The economics are clear. The technology is proven. And the long-term benefits — reduced energy costs, energy independence, carbon footprint reduction, and enhanced corporate sustainability credentials — are measurable, lasting, and significant.
The question for most organisations is not whether to invest in solar. It is who to trust to get it right. At Truven Energy Private Limited, we bring together 500+ MW of collective project experience, an uncompromising commitment to transparency, and a genuinely client-first approach to deliver solar power solutions that perform as promised — from the first conversation to the final year of operation and beyond.
We do not just install solar panels. We design, engineer, procure, construct, commission, and operate complete solar power systems — with the same rigour, care, and honesty applied at every single stage. And we do it under a single point of accountability, so our clients never have to manage complexity, chase contractors, or wonder whether the right decisions are being made on their behalf.
What Is EPC — And Why Does It Matter?
EPC stands for Engineering, Procurement, and Construction. In the context of solar power, it describes the comprehensive, end-to-end delivery of a solar power plant — from initial site assessment and detailed system design through equipment procurement, civil and electrical construction, system integration, testing, commissioning, and handover.
Choosing an EPC partner is the single most consequential decision in a solar project. The EPC contractor is responsible for every technical decision, every procurement choice, every quality standard, and every construction outcome that will determine how your plant performs for the next 25 years.
At Truven Energy, our EPC service is built on four non-negotiable principles: technical excellence, complete transparency, seamless delivery, and long-term accountability. These are not aspirations — they are the standards by which every project we undertake is designed, managed, and measured.
Every successful solar project begins with a rigorous, honest assessment of the site and a clear-eyed evaluation of its solar potential.
Our site assessment process includes:
Solar Resource Assessment: We conduct a detailed analysis of the solar irradiation profile at your site using industry-standard meteorological data, satellite-derived irradiance datasets, and on-site measurement where applicable. We do not rely on generic regional averages. We build a site-specific solar resource model that accurately reflects the generation potential of your location — across seasons, weather conditions, and time of day.
Site Survey and Geotechnical Assessment: Our engineering team conducts a comprehensive physical survey of the site, assessing available area, orientation, shading obstructions, structural constraints (for rooftop systems), soil conditions and bearing capacity (for ground-mounted systems), and access logistics. For rooftop systems, we conduct detailed structural assessments to ensure your building can safely support the intended solar installation.
Grid Connectivity Assessment: We evaluate the available grid infrastructure at or near your site — including substation capacity, feeder availability, and grid stability — to understand the connectivity options, costs, and constraints for your project. We provide an honest assessment of grid connectivity timelines and requirements, so there are no surprises during the approval or commissioning process.
Shadow Analysis and Yield Modelling: Using advanced simulation tools including PVsyst, we model the expected annual energy generation of your proposed solar system — accounting for site-specific irradiation data, shading from surrounding structures and vegetation, system losses, and equipment performance parameters. Our yield models are calibrated against real-world performance data from comparable operating assets — ensuring that the projections we present are conservative, defensible, and genuinely achievable.
Financial Feasibility Analysis: We prepare a detailed financial model for your project — including capital cost estimates, energy yield projections, grid tariff comparisons, payback period calculations, net present value analysis, and internal rate of return — to give you a complete and honest picture of the financial case for your solar investment before any commitment is made.
Detailed engineering is where a solar project is truly designed — and where the long-term performance of the plant is fundamentally determined. Poor engineering decisions made at this stage cannot be corrected by excellent construction. The foundation of a high-performing solar asset is a rigorously engineered system.
Our detailed engineering scope covers every technical aspect of your solar power plant:
System Design and Optimisation: We design your solar power system from first principles — selecting the optimal combination of panel technology, inverter topology, mounting structure, and system architecture for your specific site, load profile, and commercial objectives. We do not apply a standard template to every project. Every system we design is optimised for its specific context.
Solar Panel Layout and Shading Analysis: We develop detailed panel layout drawings that maximise the use of available area while minimising inter-row shading losses, respecting structural and access constraints, and optimising string configuration for inverter compatibility. Our layouts are developed iteratively, with multiple options evaluated and compared before a final design is confirmed.
DC System Design: We design the complete DC side of the solar system — including string configuration, DC cable sizing, combiner box specification, DC protection devices, and earthing arrangements — to minimise resistive losses, ensure system safety, and optimise inverter loading across all operating conditions.
AC System Design: We design the complete AC electrical infrastructure for your plant — including inverter output cabling, AC distribution boards, transformer specification, metering arrangements, and grid connection equipment — in accordance with all applicable Indian and international electrical standards.
SCADA and Monitoring Architecture: We design a comprehensive SCADA and remote monitoring system for your plant — enabling real-time visibility of generation data, equipment health, alarm conditions, and key performance indicators. Our monitoring systems are designed for ease of use, reliability, and long-term data integrity — giving you and our O&M team continuous, accurate visibility of your plant’s performance.
Structural Engineering: For rooftop systems, we design mounting structures that are structurally compatible with your building, wind-load certified, and corrosion-resistant. For ground-mounted systems, we design pile foundations and module mounting structures engineered for your specific soil conditions, wind zone, and module configuration. All structural designs are prepared by qualified structural engineers and documented for regulatory submission.
Bill of Materials and Technical Specifications: We prepare a complete, itemised Bill of Materials for every component in your solar system — specifying technical requirements, quality standards, testing certifications, and performance guarantees. These specifications form the basis of our procurement process, ensuring that every component sourced for your project meets the standards required for long-term, high-performance operation.
Procurement is where the quality and cost-effectiveness of a solar project are largely determined — and where many EPC contractors let their clients down, either through poor vendor selection, inflated procurement margins, or the substitution of inferior components after contract award.
At Truven Energy, our procurement process is built on three principles: technical rigour, complete transparency, and genuine independence from supplier influence.
Technology-Agnostic Vendor Evaluation: We maintain no exclusive supplier agreements and accept no commercial incentives from equipment manufacturers. Our vendor evaluations are conducted entirely on the basis of technical merit — assessing module efficiency, power output warranty, degradation guarantee, temperature coefficient, mechanical durability, and manufacturer financial stability for solar panels; and efficiency, reliability, warranty terms, grid compliance, and after-sales support for inverters and other electrical equipment.
Open-Book Procurement: We share our vendor evaluation matrices, comparative quotations, and negotiated pricing with our clients in full. You know exactly what equipment is being proposed, why it has been selected over alternatives, what it costs, and what commercial terms have been agreed with the supplier. There are no hidden procurement margins and no unexplained line items.
Global and Domestic Sourcing: We source from a carefully curated panel of global and domestic manufacturers — spanning Tier 1 solar panel manufacturers, leading inverter brands, and high-quality mounting structure fabricators. Our sourcing panel is continuously reviewed and updated based on performance data from operating projects, manufacturer audit findings, and evolving market intelligence.
Logistics and Supply Chain Management: We manage the complete logistics and supply chain for your project — including international and domestic freight, customs clearance, inland transportation, and site delivery — ensuring that equipment arrives on time, in undamaged condition, and with all required documentation and certifications.
Inspection and Quality Assurance at Source: For larger projects, we conduct factory acceptance testing and quality inspection at the manufacturer’s facility before despatch — verifying that the equipment supplied meets the specifications agreed at procurement and the quality standards required for long-term performance.
The quality of civil and structural work on a solar project has a direct and lasting impact on plant safety, structural integrity, and long-term performance. Poorly executed civil work — inadequate foundations, non-compliant cable trenching, substandard module mounting — creates risks that can manifest as safety incidents, structural failures, or performance degradation years after commissioning.
At Truven Energy, we execute civil and structural works to the highest standards — with qualified site engineers supervising every activity, comprehensive quality assurance documentation, and a zero-compromise approach to safety and workmanship.
Our civil and structural construction scope includes:
Site preparation: Clearing, grading, and levelling of the project site in accordance with design requirements.
Pile foundation installation: Driven or bored pile installation for ground-mounted module mounting structures, executed in accordance with geotechnical design specifications.
Module mounting structure erection: Installation of pre-engineered, galvanised or aluminium mounting structures in accordance with structural design drawings and manufacturer specifications.
Cable trench excavation and backfilling: Trenching, bedding, cable laying, and backfilling in accordance with cable routing drawings and civil specifications.
Control room and inverter room construction: Construction of equipment housing structures to civil and electrical design specifications.
Boundary wall and security fencing: Perimeter security infrastructure in accordance with project requirements and applicable standards.
Internal access roads and drainage: Site access roads, cable crossing structures, and surface water drainage in accordance with site civil drawings.
Every aspect of our civil construction is executed in accordance with a comprehensive Quality Assurance and Quality Control plan — with documented inspection and test records maintained for every critical activity.
Electrical installation is the most technically demanding phase of solar project construction — and the phase where the largest proportion of long-term performance and safety risks originate. Poorly executed electrical work can result in energy losses, equipment failures, fire risks, and safety incidents that persist throughout the plant’s operational life.
At Truven Energy, our electrical installation teams are qualified, experienced, and supervised by senior electrical engineers on every project. We apply the same rigorous quality standards to every connection, every termination, and every test — regardless of project scale.
Our electrical installation scope includes:
Commissioning is the process by which a completed solar power plant is systematically tested, verified, and certified as safe and ready for operational service. A rigorous commissioning process is not a formality — it is the final opportunity to identify and correct any issues before the plant enters long-term operation, and the definitive demonstration that every system and component is performing as designed.
At Truven Energy, our commissioning process is thorough, documented, and independent — with every test procedure, test result, and commissioning outcome recorded in a comprehensive commissioning report that is provided to the client in full.
Our commissioning scope includes:
Handover: Upon successful completion of commissioning, we provide the client with a comprehensive handover package — including all as-built drawings, equipment manuals, test records, commissioning reports, warranty certificates, and O&M documentation.
At Truven Energy, we understand that different clients have different financial objectives, capital availability, risk appetites, and operational priorities. A commercial model that is ideal for one organisation may be entirely inappropriate for another. That is why we offer four distinct commercial structures for solar power projects — and why we invest the time to understand each client’s specific circumstances before recommending an approach.
Maximum long-term savings: As the owner of the asset, you capture the full financial benefit of every unit of energy generated by your plant — with no tariff payments to a third-party asset owner.
Accelerated depreciation: Solar power plants qualify for accelerated depreciation under Indian tax law — providing a significant tax benefit in the early years of plant operation that substantially improves the after-tax return on investment.
Complete ownership and control: You own the asset. You control every operational decision. There are no contractual obligations to a third-party owner, no lock-in periods, and no restrictions on how you use or modify your energy infrastructure.
High lifetime ROI: For clients with available capital, the CAPEX model consistently delivers the highest lifetime return on investment of any commercial solar structure — with typical payback periods of 4 to 7 years and a remaining asset life of 18 to 21 years of largely cost-free generation.
Balance sheet asset: A solar power plant is a productive, depreciable capital asset that adds value to your organisation’s balance sheet.
Energy price certainty: Once installed, your solar generation costs are fixed for the life of the plant — providing a valuable hedge against future grid tariff escalation.
Zero capital investment: You do not invest a single rupee in the solar plant. All capital, financing, and asset ownership costs are borne by Truven Energy or its financing partners.
Immediate cost savings: Your contracted solar tariff is set below your current grid electricity cost — meaning you begin saving money from the first day of plant operation.
No technology or performance risk: Truven Energy owns the plant and is contractually responsible for its performance. If the plant underperforms against guaranteed generation levels, the financial consequence is borne by us — not you.
No maintenance responsibility: All operations, maintenance, and performance management of the solar asset is handled entirely by Truven Energy. You have no maintenance obligations, no operational complexity, and no staffing requirements for the plant.
Predictable energy costs: Your solar tariff is fixed or subject to a clearly defined, transparent escalation mechanism — providing long-term energy cost predictability that is not available from the grid.
Immediate sustainability benefits: You begin consuming renewable energy from day one — contributing to your organisation’s sustainability targets and ESG commitments without any capital outlay.
Significantly lower energy costs: Power consumed through the Group Captive Open Access model is typically priced substantially below conventional grid supply — reflecting the lower cost of renewable generation and the favourable regulatory treatment afforded to captive consumption.
Regulatory benefits of captive status: Entities meeting the regulatory criteria for captive consumption — including the minimum ownership stake requirement — benefit from a more favourable open access charge structure than third-party open access consumers, improving the overall economics of the arrangement.
Shared capital investment: The capital cost of the solar plant is shared across multiple participating entities — reducing the individual investment required from each participant while enabling access to a larger, more cost-effective plant than any single entity might develop independently.
Long-term energy cost certainty: Once the plant is commissioned and the Group Captive arrangement is registered, participating entities enjoy stable, predictable energy costs that are protected from grid tariff escalation for the life of the asset.
Collective sustainability impact: Participating entities collectively reduce their carbon footprint and strengthen their ESG credentials through shared investment in a single, high-impact renewable energy asset.
Scalability: The Group Captive model can be structured to accommodate the addition of new participants or the expansion of the plant’s capacity over time — providing a scalable framework for growing energy requirements.
The Group Captive Open Access model is best suited to industrial groups with multiple facilities across a state, corporate clusters with shared ownership structures, or coalitions of independent businesses with complementary energy profiles and a willingness to co-invest in a shared renewable energy asset. It is particularly compelling for energy-intensive industries where electricity costs represent a significant proportion of operating expenses, and where the cost savings available through Group Captive Open Access can deliver a meaningful competitive advantage.
No on-site land or space required: The solar plant is located remotely — at a site optimised for solar generation — with no requirement for the client to provide land, rooftop area, or any on-site accommodation for the generating asset.
Below-grid energy tariffs: Solar energy purchased under a Third Party Open Access PPA is typically priced significantly below conventional grid supply — delivering immediate and sustained energy cost savings without any capital investment by the client.
Zero capital investment: The client purchases energy, not an asset. All capital investment, financing, and asset ownership is borne by the plant developer — in this case, Truven Energy or its financing partners.
Scalable energy volumes: The Third Party Open Access model can be structured to supply any volume of energy required by the client — from a few million units per year to hundreds of millions — making it scalable to even the largest industrial energy consumers.
Access to large-scale, high-efficiency generation: Remotely located, utility-scale solar plants benefit from superior site conditions, optimised system design, and economies of scale — delivering energy at a lower cost per unit than small-scale on-site systems.
Immediate sustainability impact: From the first day of supply, the client is consuming certified renewable energy — contributing directly to their sustainability targets and supporting renewable energy generation at scale.
