About JAS Energy Solutions
JAS Energy Solutions FlexCo is an engineering and services company for photovoltaics and energy solutions founded in 2024 in Vienna. The company supports PV projects for single-family homes, residential construction, commerce and industry throughout Austria — from site analysis via yield simulation, module and string planning and profitability calculations through to installation, commissioning and ongoing support. The portfolio includes battery storage systems including commercial large-scale storage systems over 100 kWh for peak shaving and arbitrage, emergency power solutions, e-charging infrastructure with load management, as well as roofing and sheet-metal work. In addition, JAS offers thermography and drone inspections, maintenance, 24/7 monitoring, subsidy and permitting consulting as well as support with energy communities and energy management systems. Customers include Sozialbau AG, Wien Energie and HANSA FLEX; in 2025 a PV system with around 181 kWp was commissioned in Klagenfurt. The company is headquartered in Vienna.
