Electrical Solutions for Utility-Scale Ground-Mounted PV Plants
We engineer and manufacture complete medium- and low-voltage electrical systems for large-scale ground-mounted photovoltaic (PV) power plants. Our solutions cover every stage — from inverter output to grid interconnection — ensuring reliable operation, grid compliance, and long-term performance.
With decades of experience in power distribution and renewable integration, we provide modular, pre-assembled systems for faster EPC deployment, safer operation, and easier maintenance across hundreds of megawatts.
- Centralized or string inverter topologies
- MV collection networks up to 35 kV
- Skid-mounted or containerized power blocks
- Fully compliant with IEC / CE / ISO standards
Project Overview — Powering Utility-Scale Solar Farms
Ground-mounted PV plants are the backbone of modern solar generation, delivering hundreds of megawatts directly to the grid. These installations demand reliable medium-voltage equipment, robust transformers, and intelligent control systems that can operate continuously in outdoor environments.
We supply complete electrical solutions — from inverter stations to main substations — ensuring every connection meets grid code and performs flawlessly over the plant’s 25-year lifespan.
Typical System Architecture
Our utility-scale PV electrical chain is designed for efficiency and modular expansion:
Core Electrical Equipment Supply
Outdoor or indoor metal-clad switchgear designed for reliability and safety. Includes SF₆ or solid-insulated options, integrated protection relays, and arc-flash containment for collector stations.
Compact gas-insulated or solid-insulated RMUs enable flexible feeder connections within MV rings. Ideal for distributed PV block architectures where redundancy and service continuity are key.
Oil-immersed or dry-type step-up transformers (400 V→33 kV / 35 kV). Customized for high ambient temperature, low losses, and long service life under continuous load.
Located near inverter stations. Provide control, auxiliary supply, protection, and monitoring at LV level. Factory-tested assemblies minimize onsite wiring.
Full monitoring and control of each feeder and transformer via SCADA integration. Real-time status, alarms, and data logging improve plant availability and performance.
Case Example — 100 MW Utility-Scale PV Plant
This 100 MW solar farm was built across 200 hectares of land with 400 inverters and 50 power blocks. We supplied 35 kV medium-voltage switchgear, ring main units, step-up transformers, and low-voltage panels for each inverter skid. All units were delivered as pre-assembled modules for faster commissioning and lower onsite risk.
The plant has achieved over 99.95% availability since commissioning, providing renewable energy for more than 200,000 households annually.
