Syntegra Solar International

What Syntegra Solar International does

Syntegra Solar International AG (SSI AG) is a Basel, Switzerland-headquartered consulting and advisory firm specializing in renewable energy and solar PV across Southeast Asia (Philippines, Vietnam, Malaysia, Thailand), the Gulf, Baltic, and Caribbean. The company was founded circa 2001 and delivers four core service families: (1) Technical Due Diligence (TDD) and M&A Technical Advisory for institutional investors and developers; (2) Lender's Technical Advisory (LTA) and Owner's Engineer (OE) services for banks financing utility-scale PV power plants; (3) EPC Project Management for utility-scale and C&I rooftop installations; and (4) Technology Innovation leveraging the PEG® low-height PV substructure (exclusive SEA sales agency for Jurchen Technology GmbH's patented three-part design) and FPV® floating solar (pioneered through the 220 kWp Magat River demonstration with Ocean Sun AS).

The firm monetizes through project-based professional services fees, EPC contract revenue via two jointly controlled subsidiaries (Tona Syntegra Solar in Vietnam with TONA Corp., and Syntegra Solar Thailand with Aspire Holding), sales commissions on PEG® substructures across eight SEA markets, and emerging EE/PV energy efficiency services developed jointly with Viessmann Group's Etanomics. Customer segments are organized around the high-stakes decision points of SEA PV development: banks and lenders requiring independent technical validation (e.g., Land Bank of the Philippines), project developers and asset owners needing owner's engineering and M&A buy/sell-side advisory (e.g., Bronzeoak Philippines, Macquarie/PINAI, ThomasLloyd, SN Aboitiz Power, PetroSolar, Citicore Power, ACWA Power), and C&I facilities pursuing turnkey rooftop EPC.

The company's competitive narrative rests on two decades of SEA-specific technical depth: founders Mathias G. Kothe (MIT Sloan MBA, 33 years RE/PV innovation) and Rainer Schott (33 years IT project management across <860 MWp) anchor a multidisciplinary team supplemented by regional partners (Pratch Kottanu and Moritz Sticher, each with 12-18 years of SEA PV development). Quantified credentials include >4.76 GWp of RE/Solar PV projects engaged as LTA/OE/M&A advisor, ~2 GWp of M&A TDD across 2021-2023, and ~60 MWp of EPC developed and commissioned in SEA. Private, partner-led, and without disclosed external funding, the firm operates with a 11-50 employee core augmented by JV partners for regional execution.

• Clean Energy Associates (CEA): Solar PV quality assurance, owner's engineering and technical advisory firm serving developers, lenders and investors across Asia — directly comparable niche competitor in PV-focused independent engineering.
• DNV: Global energy advisory and certification firm offering lender's technical advisory, owner's engineering and technical due diligence for utility-scale solar PV projects worldwide, including Southeast Asia — the most directly comparable full-scope competitor to Syntegra's core consulting practice.
• Enertis: Specialized solar and storage technical advisory firm offering owner's engineering, lender's technical advisory and independent engineering services; competes for similar PV-focused advisory mandates globally including in Asia-Pacific.
• Fichtner: German engineering consultancy with a strong renewable energy advisory practice including owner's engineer, lender's technical advisor and bankability studies — directly comparable to Syntegra's German-engineering heritage and SEA footprint.
