First, what “EPC” means:

EPC stands for Engineering, Procurement, and Construction.
One team plans the system, buys the right parts, builds it, and hands it over in working condition. You deal with one accountable partner. No finger-pointing. No gaps.

What happens before work starts

Good projects start with clear facts. We begin with:

Site assessment: Roof or land checks. Shadow analysis. Access, wind, soil (for ground-mount). Safety and structural checks.
Solar resource study: Sunlight data and on-site conditions.
Energy yield estimate: Expected monthly and yearly generation.
Load and tariff review: Your consumption pattern and current costs.
Business case: CAPEX or OPEX model, payback, and cash flow.
Regulatory scan: Net metering or open access scope. Local rules. Utility constraints.

If you want an independent view before any build, ACE Renewtech also offers a solar power plant consultancy service. This covers feasibility studies, due diligence, LCOE insights, and bid support.

Engineering: turning a plan into a buildable design

This is where design choices lock in performance and safety.

System sizing: Based on space, budget, and your load profile.
Layout and strings: Module placement, string size, and routing to cut losses.
Electrical design: DC and AC design, cable sizing, protection, earthing, lightning, SLDs.
Structures: Roof mount, ground mount, ballast or pile. Wind and load checks.
Inverters and transformers: Central or string inverters. LV/MV interface.
Monitoring and control: SCADA or online portals for live tracking.
Compliance: Local codes and standards. Utility interconnection rules.

Design must be practical. It should reduce losses, ease future maintenance, and meet all safety norms. We document assumptions and share drawings so you know what you will get.

Procurement: buying the right components, not just cheap ones

The bill of materials is large. It includes modules, inverters, structures, cables, protection devices, junction boxes, earthing kits, transformers, switchgear, communication gear, and more.

Vendor selection: Based on proven quality, warranties, and delivery reliability.
Certification checks: IEC and BIS compliance where required.
Factory inspections: As needed for critical items.
Logistics planning: On-time deliveries to match the build schedule.
Spares strategy: Essential spares defined upfront for faster repairs.

Cost matters. But total lifetime value matters more. We aim for the lowest cost per kWh over the life of the plant, not just the lowest price today.

Construction: building safely and on schedule

A safe and tidy site is a productive site.

Site setup: Safety plans, barricading, storage, and QA procedures.
Civil and structural works: Foundations or ballast, walkways, and drainage.
Module mounting: Careful handling to protect glass and backsheets.
DC works: String wiring, combiner boxes, and terminations.
AC works: Inverter stations, transformers, switchgear, and metering.
Cabling and earthing: Correct routing, labeling, and test reports.
Grid tie-in: Utility interface built to spec.
Testing and commissioning: IV curves, insulation, protection, and performance checks.

Clear documentation follows each step. You see what was built and how it was tested.

Approvals and handover

We coordinate with the utility and authorities for:

Net metering or open access permissions
Safety inspections and test reports.
Meter installation and witness testing.

You receive a complete handover pack: as-built drawings, warranties, manuals, test certificates, and training for your team.

Operations and maintenance (O&M)

Solar is not “fit and forget.” Clean panels and healthy equipment keep your output steady.

Monitoring: 24/7 performance tracking with alerts.
Preventive maintenance: Scheduled cleaning, torque checks, thermography, and inspections.
Corrective maintenance: Swift fault finding and fixes.
Spares and support: Defined SLAs and response times.
Performance review: Monthly reports, PR and CUF tracking, loss analysis, and improvement actions.

Good O&M protects your investment and keeps the business case on track.

EPC vs consultancy: which one do you need?

Choose EPC when you want a single partner to design, build, and deliver a working plant. One contract. Fixed scope. Clear timelines
Choose solar power plant consultancy service when you want independent advice, feasibility checks, owner’s engineering, or support for tenders and vendor evaluation. You can use this before EPC or alongside it to add oversight.

ACE Renewtech provides both. You can start with consultancy and move to EPC with us, or keep them separate. Your call.

Delivery models we support

CAPEX: You invest. You own the plant. You get full savings
OPEX (RESCO/lease): A developer owns the plant. You buy power via PPA. Lower upfront spend.

We help you compare options with clear numbers. No inflated claims. Just data and risks noted plainly.

Where EPC fits: rooftop, ground mount, and more

We build for:

Rooftop (C&I and institutional): On RCC, metal, or elevated structures.
Ground-mounted (utility and captive): From a few MW to large parks.
Hybrid and storage: Solar with batteries or diesel offset.
Carports and special sites: Where space needs a dual use.

Each site has quirks. We design for that, not for a template.

Quality, safety, and compliance

We follow standard checklists for all critical activities. We track non-conformities and fix them early. We use lockout-tagout, PPE, working-at-height rules, and electrical isolation practices. We test before we energize. This protects people and assets.

Timelines and costs: a realistic view

Timelines depend on size, site readiness, and approvals. A small rooftop can take weeks. A large ground mount can take months. Costs depend on modules, inverters, structures, cabling distances, and grid interface. We share a transparent BOQ and schedule so you can plan ahead. If something shifts, you know why and what it means.

Why work with ACE Renewtech

Single point of accountability: One team from idea to operation.
Clear design and documentation: You see the logic and the drawings.
Quality components: Balanced with availability and service.
On-site safety: Non-negotiable.
Steady O&M: To protect generation and uptime.
Flexible engagement: Full EPC or standalone consultancy — your choice.

We keep the language simple and the process visible. No hidden steps. No flashy claims.

Quick FAQ

Is a solar EPC company the same as an installer?
Not exactly. An installer may just mount and wire. An EPC partner designs, procures, builds, commissions, and coordinates approvals, then supports operations.

Can I start with a study before I commit?
Yes. Our solar power plant consultancy service gives you feasibility, yield, and financial clarity before you decide.

What happens if my load changes later?
We plan for future expansion where possible. We also guide you on upgrades, storage, or policy options if your load grows.

Conclusion:

A solar EPC company owns the heavy lift of design, buying, building, and handover. It keeps the project accountable and the risks managed. With ACE Renewtech, you can choose full EPC or start with consultancy. Either way, you get a clear plan, a safe build, and steady operation — so your plant does what it should: deliver clean, reliable power at a fair cost.
