What Waldevar Solar One Srl does
WALDEVAR Energy (legal entity Waldevar Solar One Srl / WALDEVAR Energy S.R.L.) is a privately held Romanian engineering, procurement, and construction (EPC) contractor specializing in the design, construction, and maintenance of large-scale and floating photovoltaic (FPV) solar parks. Founded in 2011 and headquartered in Tulcea with operational offices in Voluntari (Ilfov), the company serves utilities, energy companies, and industrial clients across Europe, with completed projects including a 9.13 MWp installation at Căzănești/Ialomița and a 34 MWp installation at Mircea Vodă/Constanța. Its service portfolio spans full-scope ground-mounted and floating PV EPC, operations and maintenance, mobile PV systems, structural pull-out load testing, and — following the 2026 acquisition of high-voltage specialist ELEMO — grid connection and substation infrastructure through the WALDEVAR Power Grid service line.
Technically, Waldevar's stack is built around conventional PV and FPV engineering rather than software platforms. Core capabilities include in-house EPC project execution from feasibility and consultancy through construction and operational management, specialized floating photovoltaic deployment on water bodies, mobile/portable PV configurations, and complex load/pull-out testing for structural integrity verification. The grid-side layer (WALDEVAR Power Grid) extends the offering into high-voltage substation design and construction, which the company describes as creating Romania's first fully integrated renewable energy infrastructure platform. The company holds ISO 9001, 14001, and 45001 certifications, alongside Romanian energy regulator ANRE authorizations of types A3, D1, D2, E1, and E2 plus an ISC construction license (ISC 2528, August 2025).
Commercially, Waldevar earns revenue through two streams: one-time EPC contract revenue from utility-scale and floating PV construction projects awarded via competitive bids and direct negotiation with utilities, industrial firms, and developers, and recurring operations and maintenance service revenue on completed installations. The go-to-market is enterprise field sales, with multi-year project-based pricing determined by installed MWp capacity, site conditions, and scope. The company is currently expanding into Italy, Germany, and the Czech Republic, has a 200+ MWp solar park co-development with Entek Elektrik, and a high-voltage substation EPC partnership with GEN-I Sonce. Ownership is concentrated under WALDEVAR Holding with no disclosed external investors or funding rounds in the available data.
