, What we do

Five disciplines.
One delivery model.

Engineering, procurement, construction, storage, and the agrivoltaic work that comes with it. Each one self-performed , we do not subcontract the load-bearing engineering or commissioning.

End-to-end, load-bearing engineering kept in-house.

Engineering & feasibility studies

Bankable site selection, yield modelling, grid-integration studies, IFC/EBRD-grade ESIA , delivered by an in-house team of 64 engineers across electrical, civil, geotechnical, and environmental disciplines. We don't outsource the work the lenders are going to read.

Procurement & supply-chain control

Tier-1 OEM relationships negotiated from inside the supply chain , our Qingdao HQ removes the middlemen. Multi-currency hedging, bonded warehousing in three regional hubs (Qingdao, Marseille, Basra). We don't lose six months at a port-of-entry permit because we have already cleared the next 60 containers.

Construction & site commissioning

Self-perform civils and electrical for sites above 50 MW. Locally trained crews everywhere we build , over 2,400 local engineers and technicians trained to date. Commissioning under IEC 62446 , every string tested before energization, every test result in the lender's report.

Battery energy storage integration (BESS)

AC- and DC-coupled BESS up to 400 MWh, designed for arbitrage, capacity firming, and ancillary services. We dispatch our own SCADA stack and provide a 10-year performance warranty on round-trip efficiency , not just on availability, which is what most counterparties offer.

Agrivoltaic systems & land-use integration

Elevated arrays designed in consultation with regional agronomists , preserve cropland yield while generating power above it. Eight years of operating data across three climatic zones, including our Iraq greenhouse pilot. Co-revenue models for landowners as standard.

02 / Methodology

Four phases. Each one ends in a signed transfer.

The delivery model is deliberately linear. Each phase is contractually independent , investors can engage at any stage and exit at any phase boundary.

PHASE 013–9 months

Feasibility & bankability

Site selection, ESIA, yield modelling, grid-integration study, financial modelling. Output: bankable due-diligence package.

  • Geotech + topographic surveys
  • P50/P90 yield
  • IFC ESIA
  • Financial model · IRR / DSCR
PHASE 029–18 months

EPC delivery

Detailed engineering, procurement, construction. Single-counterparty EPC contract , fixed price, date-certain, performance-guaranteed.

  • Detail design freeze
  • Procurement & logistics
  • Civil works
  • Electrical install
PHASE 032–4 months

Testing & commissioning

String-level testing, energization, grid synchronization, performance-ratio acceptance. PR-guarantee threshold met before sign-off.

  • IEC 62446 acceptance
  • Hot commissioning
  • 30-day PR test
  • Lender's engineer sign-off
PHASE 04Ongoing · O&M optional

Operator handover

Asset transfer to the owner-operator. Optional 5–10 year O&M contract with availability and PR guarantees attached.

  • Final as-builts
  • O&M handbook
  • Local crew handover
  • Performance bond
