How we work
The EPC Process, Explained
EPC stands for Engineering, Procurement, and Construction — the three pillars of a complete solar power plant delivery. HillRockS International manages every phase, from initial site survey and government form submissions to final plant commissioning.
Engineering
Site Survey, Design & Documentation
We begin with a thorough site assessment, solar resource analysis, and load profiling. Our engineers prepare detailed project reports (DPR), single-line diagrams, structural drawings, and all documentation required for government approvals and plant setup form submissions.
- Site feasibility study
- Detailed Project Report (DPR)
- Plant layout & structural design
- Government form filling & approvals
- Grid connectivity documentation
Procurement
Equipment Sourcing & Supply Chain
We source and procure high-quality solar modules, inverters, mounting structures, cables, and balance-of-system components from MNRE-approved and BIS-certified vendors, ensuring compliance with government tender specifications.
- MNRE-approved solar modules
- String & central inverters
- Mounting structures (ground/rooftop)
- HT/LT cables & switchgear
- Monitoring & SCADA systems
Construction
Installation, Testing & Commissioning
Our certified installation teams execute civil, structural, and electrical works with precision. We conduct rigorous testing, inspection, and commissioning procedures, followed by handover documentation and grid synchronisation.
- Civil & structural works
- Module mounting & wiring
- Inverter & transformer installation
- Testing, inspection & commissioning
- Grid synchronisation & handover

Why solar for government projects
The Case for Solar Energy in Public Infrastructure
India's government sector is at the forefront of the nation's renewable energy transition. Solar power offers measurable, long-term advantages for public institutions and infrastructure projects.
Zero Fuel Cost
Solar energy eliminates recurring fuel expenditure. Once installed, a solar plant generates electricity at near-zero marginal cost for 25+ years, delivering significant savings to public budgets.
Reduced Electricity Bills
Government buildings and facilities typically achieve 30–60% reduction in electricity bills through rooftop and ground-mounted solar installations, freeing funds for core public services.
National Policy Alignment
India's National Solar Mission targets 500 GW of renewable capacity by 2030. Government projects adopting solar directly contribute to national energy security and climate commitments.
Long-Term Asset Value
Solar plants are long-life infrastructure assets with minimal maintenance requirements. With a 25-year performance warranty on modules, they deliver consistent returns on public investment.
