EPC for solar and energy storage
GREEN UNION PTE. LTD. provides engineering, procurement and construction services for photovoltaic and energy-storage projects. From a Singapore base we take programmes from early design through construction and handover.
Solutions
Solar and storage, designed and built as one programme
We cover the project types that typically sit inside a photovoltaic and energy-storage EPC mandate: ground-mount plants, rooftop arrays, battery systems, and combined solar-plus-storage sites.
01
Utility-scale photovoltaics
Ground-mount solar plants engineered, procured and constructed as a single delivery.
02
Commercial rooftop solar
Rooftop arrays for industrial and commercial sites, scoped to structure, load and grid connection.
03
Energy storage systems
Battery energy storage specified, installed and commissioned for site or grid use.
04
Solar-plus-storage
Hybrid plants where generation and storage are designed, built and handed over together.
What we do
A full EPC path, not a single trade
The company is the counterpart for engineering, procurement, construction and commissioning — so a photovoltaic or storage project is not split across disconnected vendors.
Engineering
Layout, electrical design and construction documentation for solar and storage plants.
02Procurement
Modules, inverters, batteries, balance-of-plant and logistics aligned to the design.
03Construction
Site works, mechanical and electrical installation under a controlled construction plan.
04Commissioning
Testing, grid-connection support and documented handover of a working plant.
How we work
From site assessment to a working plant
Each engagement follows a controlled sequence so design, equipment and construction stay on the same specification.
01
Assess
Site conditions, interconnection options and the client’s performance brief are recorded first.
02
Design
Engineering locks layout, electrical architecture and construction packages before procurement.
03
Procure
Equipment and materials are sourced to the approved design, not substituted ad hoc on site.
04
Build
Construction follows the issued drawings, with inspection points through mechanical and electrical works.
05
Hand over
Commissioning, documentation and training close the EPC scope when the plant is ready for operation.
