Engineered for Performance

Turnkey Solar EPC Services

ONE POWER delivers full-service Solar EPC capabilities for commercial rooftop, industrial, and ground-mounted utility PV power plants.

Engineering (E): Performing site irradiation analysis, shading simulations, structural load calculations, and electrical circuit design to maximize yield.

Procurement (P): Sourcing tier-1 PV modules, high-efficiency string/central inverters, heavy-duty mounting structures, and transformer switchgear at competitive costs.

Construction (C): Executing foundation civil works, structural assembly, DC/AC cabling, substation wiring, and grid interconnection under strict safety management

Electrical & Telecommunications Infrastructure

As a fully licensed electrical contractor, we engineer and construct essential power networks for public institutions, commercial complexes, and smart industrial parks. Our scope encompasses high-voltage substations, indoor/outdoor lighting, cable tray installations, municipal streetlight networks, and IT fiber-optic infrastructure

Smart O&M & Remote Telemetry Systems

Solar assets require continuous monitoring to maintain peak performance. ONE POWER’s proprietary IoT telemetry system connects field sensors directly to our central monitoring center, performing automated diagnostic checks, predicting component failures, and alerting dispatch teams to prevent operational downtime

Global Renewable Energy Development

Extending our engineering expertise across international markets:

Southeast Asia (Vietnam, Indonesia, Myanmar): Conducting utility-scale solar land surveys, regulatory reviews, grid capacity assessments with state utilities like PLN, and PPA structuring.

Philippines: Completed turnkey Solar EPC construction in General Santos.

Africa (Madagascar, Seychelles): Awarded off-grid solar PV EPC projects designed to provide reliable electricity to rural healthcare and community facilities
