Built for commercial and industrial clients who demand industry-leading technical depth.

Before construction begins, we do the work that determines whether your project will perform over its entire 25-year asset life. We conduct comprehensive site feasibility studies — evaluating roof or land suitability, grid connectivity, irradiance, and structural conditions — and produce rigorous energy yield models in PVsyst, with fully documented loss parameters and P50/P90 sensitivity analysis for your finance team.

Where independent technical oversight is required, our engineering mandate is ring-fenced from our EPC scope — providing your leadership team and financiers with conflict-free quality assurance on design, procurement, and construction.

What we deliver:

• Site feasibility study and technical due diligence
• Irradiance and resource analysis
• PVsyst energy yield modelling (P50/P90)
• Grid connectivity assessment
• Owner's Engineer appointment and scope definition
• Detailed Project Report (DPR) with financial model and IRR sensitivity

Our engineering team produces the complete design package before construction mobilises — optimised plant layout, single-line diagrams, civil and structural drawings, cable schedules, and a Bill of Quantities tied to the project financial model. Procurement is managed as a supply chain discipline: Tier-1 vendor qualification, factory acceptance testing, and delivery scheduling that keeps the construction programme on critical path.

On site, our project managers operate to a written Quality Management Plan with defined hold and witness points at every major construction milestone. Safety is not a parallel workstream — it is embedded in every method statement and daily toolbox talk.

What we deliver:

• Detailed engineering design (electrical, civil, structural)
• Approved Vendor List (AVL) management and Tier-1 procurement
• Factory acceptance tests and logistics coordination
• Construction management and HSE supervision
• Quality Management Plan and Inspection & Test Plan
• Progress reporting and cost tracking against earned value

Grid interconnection is where many C&I solar projects lose time — and facility owners lose money. TerraFlux manages HT connection engineering, protection coordination, and DISCOM approval workflows for rooftop, captive, and open access installations — eliminating the coordination gap between your solar EPC contractor and the grid interface that causes most commissioning delays.

We manage the full DISCOM interconnection approval process — load flow studies, protection coordination, relay settings, and synchronisation testing — starting early in the project timeline, not after installation is complete.

What we deliver:

• HT grid interconnection engineering and execution
• Protection coordination study and relay settings
• DISCOM interconnection application and approval management
• Pre-commissioning testing (IV curve tracing, insulation resistance, relay function)
• Grid synchronisation and commercial operation declaration (COD)

Commissioning is not the end of our responsibility — it is the beginning of the asset's productive life. We hand over every project with a complete documentation package: as-built drawings, O&M manuals, equipment warranties, test reports, and a commissioning certificate structured for lender sign-off.

For clients who want ongoing performance assurance, we provide yield tracking and variance analysis against the modelled P50 baseline, BESS dispatch performance reporting, and long-term asset optimisation recommendations — turning operational data into decisions that protect your returns across the full project life.

What we deliver:

• Complete handover documentation package (as-built drawings, O&M manuals, warranties)
• Commissioning certificate and lender sign-off support
• Yield tracking and P50 variance reporting
• BESS dispatch performance analysis
• Long-term asset optimisation advisory
• Annual technical due diligence for refinancing and asset sale
