Turnkey EPC: Rooftop & Ground-Mount Projects

High-Performance Utility & Distributed Solar Engineering

Solar Quest is a full-service EPC provider delivering precision-engineered solar installations across institutional, commercial, transit, utility, and industrial sectors. From high-capacity transit terminals to multi-megawatt ground-mount solar farms, we build resilient solar assets engineered for peak yields over decades.

1. Utility & Industrial Ground-Mount CAPEX Projects

We undertake turnkey execution of ground-mounted solar projects on private, institutional, and industrial lands under the CAPEX model. Our scope covers complete land grading, geotechnical and pile testing, robust MMS (Module Mounting Structure) fabrication, high-voltage switchyards, pooling substations, and dedicated transmission lines.

2. Industrial & Transit Rooftop Installations

Our rooftop portfolio covers multi-megawatt transit systems (including 20 MWp across BMRCL Bangalore and 7+ MWp across CMRL Chennai) as well as multi-site programs across 1500+ state utility sites (KPTCL Karnataka), utilizing high-density East-West (E-W) dual-tilt configurations and aerodynamic ballasted designs.

Key EPC Advantages:

Flexible Financial Models: CAPEX & RESCO / PPA

Tailored Investment Structures for Rooftop and Ground-Mount Assets

Solar Quest offers versatile deployment structures designed to fit your financial goals—whether your priority is maximum lifetime return on investment or immediate operational cost reduction with zero capital outlay.

1. CAPEX Model (Turnkey Client Ownership)

In the CAPEX (Capital Expenditure) model for rooftop and ground-mount plants, the entire solar PV system is funded and owned directly by the client. Solar Quest delivers turnkey EPC execution.

• Maximum Long-Term ROI: Realize 100% of the generated power savings immediately, achieving system payback in 3–4 years.
• Tax & Depreciation Benefits: Avail accelerated depreciation (AD) and statutory tax incentives for renewable energy infrastructure.
• Full Asset Ownership: Complete authority over equipment selection, land use, and plant output.

2. RESCO / PPA Model (Zero-Capex / OPEX)

Under our RESCO (Renewable Energy Service Company) / Power Purchase Agreement model, Solar Quest finances, designs, builds, operates, and maintains the solar power plant with zero upfront capital investment from your business.

• Zero Capital Outlay: Retain core funds for business expansion while lowering energy overheads.
• Guaranteed Tariff Savings: Purchase clean power at fixed, pre-agreed rates substantially lower than commercial grid tariffs.
• Risk-Free Performance: We assume all operational, generation, and component risks with guaranteed performance ratios (PR).

PM-KUSUM Scheme Execution

Decentralized Solarization for Agriculture & Rural Feeders

Solar Quest actively participates in executing projects under the Government of India's flagship PM-KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan) scheme, driving clean energy access, farmer empowerment, and grid stability.

Our Capabilities Under PM-KUSUM:

• Component A (Decentralized Ground-Mounted Plants): Turnkey EPC and grid-synchronization of small solar plants (500 kW to 2 MW) on barren/agricultural land connected to rural 33/11 kV substations.
• Component C (Feeder-Level Solarization - FLS): Solarization of dedicated agricultural distribution feeders under the CAPEX/RESCO model to supply reliable daytime power for irrigation.
• End-to-End Execution: Detailed site topography, civil piling, HT transmission line erection, DISCOM bay connectivity, and long-term O&M compliance as per MNRE guidelines.

Operations & Maintenance (O&M)

Data-Driven Telemetry & Preventive Plant Health Management

A solar PV plant's financial return depends directly on operational uptime. Solar Quest provides comprehensive Annual Maintenance Contracts (AMC) and asset management services driven by proactive monitoring and rapid breakdown resolution.

Our dedicated operations team ensures peak plant health through structured maintenance schedules, string-level electrical troubleshooting, and mechanized cleaning solutions.

Our O&M Service Portfolio:

• Preventive Maintenance: Regular IV-curve tracing, thermal imaging/hotspot analysis, torque checks, and inverter servicing.
• Predictive Analytics: Real-time SCADA telemetry tracking daily generation, degradation, and weather-corrected performance ratios.
• Corrective & Breakdown Support: Rapid-response field teams for emergency component replacements and grid synchronization faults.
• Automated Module Cleaning: Optimized wet and dry cleaning cycles to eliminate soiling losses and maximize generation.
