Solar EPC

What solar EPC means, who this page is for, and what happens next

Solar EPC stands for engineering, procurement and construction. One contractor designs the plant, buys the equipment and builds it through to commissioning, so one party answers for the result. Heaven Green Energy, headquartered at Mota Varachha, Surat, delivers turnkey ground-mount solar EPC and also acts as the execution subcontractor for other solar EPC companies. For a plain-language definition, read what is solar EPC.

Who it is for

  • Solar and EPC companies that need an execution partner for tender-based work
  • Developers, landowners and investors building a ground-mount plant, see ground-mount solar parks
  • Businesses with a roof or open land, see industrial and commercial solar

What the EPC covers

  • Design and site survey
  • Engineering and procurement
  • Installation and commissioning
  • Operations and maintenance after handover

What happens next

Send your company, location, capacity, project status and scope through the form. Our team reviews the tender or the site and follows up with a proposal.

Scope

What a turnkey EPC contract covers, phase by phase

This is how we split the work. The contract states the exact boundaries for your project.

PhaseWhat is done

ProcurementModules, inverters, mounting structures, DC and AC cables, protection, earthing and monitoring equipment, sourced from tier-1 manufacturers and matched to tender norms and GUVNL specifications.
ConstructionSite preparation and civil works for ground-mount plants, structure and module installation, wiring, inverter and electrical connections.
CommissioningGrid interconnection and metering, testing, grid synchronisation and handover documentation.
Operations and maintenancePreventive cleaning, performance monitoring, breakdown response and annual health reports.

Phase scope follows our solar EPC guide and the process described on this page.

Agree these in writing before you sign any EPC contract

  • Who owns land checks, surveys and the site data.
  • Who files the DISCOM, CEI and other approvals.
  • The equipment list: module, inverter, structure and cable makes, and their warranties.
  • Where civil and electrical scope ends, including the evacuation line.
  • The commissioning tests and the documents handed over.
  • The O&M term, response time and reporting.
  • Payment milestones, and which of them depend on commissioning.
Choosing a model

Turnkey EPC compared with the alternatives

Turnkey EPC

One contractor owns design, procurement and construction through commissioning. You deal with one party for delivery and performance.

Split contracts

You hire the designer, the equipment supplier and the installer separately and manage the gaps between them. More control, more coordination risk.

Ownership models

Captive use, third-party PPA, selling to the DISCOM or a RESCO arrangement decide who owns the plant and who buys the power. An EPC contractor builds the plant under any of them. See solar park project models.

FAQ

Solar EPC, Common Questions

Scope, subcontracting, timelines and what to send.

Still have questions?
What is solar EPC?
EPC stands for engineering, procurement and construction. One contractor designs the solar plant, buys the equipment and builds it through to commissioning, so a single party is accountable for the result. The model is also called turnkey EPC.
What does a turnkey solar EPC contract include?
Site survey and design, engineering, procurement of modules, inverters, structures and balance-of-system equipment, civil and electrical construction, grid interconnection, testing and commissioning, and handover documents. Operations and maintenance can follow as a separate stage. The exact scope is written into the contract, so agree the boundaries before you sign.
Do you work as a subcontractor for other EPC companies?
Yes. Heaven Green Energy serves as a subcontractor for solar EPC companies, delivering tender-based project execution to the client's specification and tender norms. Send the tender or project details through the form above.
How is EPC different from buying equipment and hiring an installer separately?
With split contracts you coordinate the designer, the equipment supplier and the installer yourself, and any gap between them becomes your risk. Under EPC one contractor owns design, procurement and construction, so there is one point of accountability for performance and delivery.
How long does a solar EPC project take?
It depends on size, site and approvals. As a typical range, commercial and industrial projects of 10 to 500 kW take 8 to 16 weeks, and large solar parks of 1 to 50 MW take 6 to 12 months. Your project timeline is fixed after the site survey and approvals review.
Is operation and maintenance part of the EPC?
It is the last stage of our process: preventive cleaning, performance monitoring, breakdown response and annual health reports after commissioning.
What should I send to get an EPC quote?
Your company name, location, project capacity, project status and the scope you want covered. Those are the fields on the EPC quote form above. If the work is tender-based, send the tender documents as well.
