A single contract, a single accountable partner. TPC Solar delivers C&I rooftop, ground-mount, and utility-scale projects end-to-end — including storage and grid interconnection.
Most solar project delays don't happen at the panel or the inverter — they happen at the interfaces. Between the designer and the procurement team. Between the main contractor and the substation subcontractor. Between the lender's engineer and the utility. A single EPC contract collapses those interfaces. The schedule, the specification, the warranties and the accountability all sit in one place.
A single scope of work takes you from site feasibility to commissioning and continues into long-term O&M. No coordination gaps between designers, suppliers and contractors.
Every project moves through the same six phases. Each phase has a fixed gate — you know exactly what is being delivered, by when, and what you sign off on before the next one starts.
Site survey, solar resource data, shading analysis, interconnection feasibility, LCOE modelling. Output: feasibility report with capacity range, indicative CapEx and LCOE.
2–4 weeksSingle-line diagram, PV layout, equipment BoM, yield forecast (P50/P90), fixed-price EPC proposal with performance guarantees.
3–6 weeksEPC contract executed, detailed engineering package produced, permit applications filed, equipment orders placed with OEMs.
8–12 weeksFactory acceptance testing, shipping, customs clearance and on-site delivery. Cold-chain logistics for BESS cells where required.
8–20 weeks (parallel)Mobilisation, civil works, structural and electrical installation, MV substation build, final testing and commissioning. Weekly progress reports with drone imagery.
12–36 weeks depending on sizeGrid synchronisation, utility witness testing, performance-ratio validation, as-built documentation, spare parts delivery, O&M contract activation.
2–4 weeks + ongoing O&MFactory, warehouse, and distribution-centre rooftops. Ballasted flat-roof and rail-mount systems, net-metering or wheeling configurations, optional on-site storage.
Captive generation for industrial loads — cement, steel, desalination, oil & gas auxiliary power. Fixed-tilt and tracker configurations.
Independent Power Producer projects with long-term PPA structure. Central inverter architectures, MV substations, SCADA integration, grid-forming BESS where specified.
Containerised LFP storage added to existing or new PV sites — peak shaving, frequency regulation, or grid-forming applications.
PV + diesel + battery microgrids for remote industrial sites, agricultural processing, and grid-edge locations with unreliable utility supply.
Packaged substations and interconnection works delivered under the same EPC contract. Transformer, MV switchgear, protection, metering and utility witness testing included.
Most of our EPC contracts are structured as fixed-price turnkey with performance-ratio and availability guarantees. The risk of site conditions, OEM delays and cost overruns sits with us — not with you.
500 MWp delivered across 17 countries. 98% on-time closure against original COD. Zero lost-time incidents.
Civil, electrical, structural, grid-interconnection, safety, commissioning — each discipline visible in what actually gets executed on site.
Transformer specification, switchgear selection, protection-relay settings, grid-code compliance testing and utility coordination are TPC scope — not a sub-contract the developer has to project-manage themselves.
That integration is why our projects hit COD on schedule and why the independent-engineer report comes back without open action items.
The project doesn't stop at first kWh. Our O&M contracts keep the plant producing at design-basis performance for the full asset life.
Safety performance is the clearest leading indicator of construction quality. Sites that run safely run on schedule, and the reverse is also true.
Our engineering studio is the quiet part of the business that everything else depends on. PVsyst and PlantPredict modelling is the visible output, but upstream of that sits the real work: albedo measurement, soiling assumptions, tracker geometry, inverter sizing ratios, clipping strategy, cable sizing, short-circuit studies, protection coordination, grid-code compliance modelling, SCADA architecture. Every decision gets written into a design basis document that the construction team is held to.
We also run lender technical advisor diligence on our own designs before we sign a contract. A design that cannot stand up to independent review is a design we would not build.
"We awarded TPC a 180 MW EPC on single-source negotiation after their technical response came back better than three competitive bids. They hit COD six weeks early. I have nothing else to add."
The three counterparties who evaluate an EPC through different lenses — each reporting back independently, each in their own words.
We ran the technical response through our independent engineer before even opening the commercial envelope. It was the most complete submission we had ever received on a sub-200 MW procurement.
Their engineering desk caught two issues in our own IE's study and quantified them in the proposal. That is not a thing other EPCs do — most would have just closed the loop and moved on.
We approved the TPC package for bankability after two working sessions. The warranty stack, the performance bond, the LTA acceptance — everything was in place. Our credit committee had no outstanding items.
Send us a location, a target capacity, and a rough timeline. We'll come back within 5 business days with a feasibility response and an indicative LCOE.
