What Geosun does
Geosun s.r.o. is a privately held Czech company founded around 2009 and headquartered in Soběslav, operating across three integrated activities: wholesale distribution of photovoltaic and heating components, in-house manufacturing of selected equipment, and exclusive Czech distribution of the Infigy smart energy management platform. Its product portfolio spans photovoltaic panels (AIKO with ABC back-contact technology and Swiss Solar with half-cell architecture), Solinteg hybrid inverters and battery storage (2.56 kWh modules up to 64–112 kWh Integ E Series), in-house manufactured FVE switchgear built with ABB components, the proprietary ECO-ONE line of compact indoor heat pump units (HW, DHW, AiHW, iFHW variants) paired with Mitsubishi outdoor units, floor heating systems, and flow-through electric boilers. The company's go-to-market is a horizontal B2B wholesale model targeting certified installers, system integrators, and construction companies across residential, commercial, and utility-scale segments in the Czech Republic and potentially the broader Central European market, supported by free technical training and installation support rather than direct consumer marketing. Geosun is founder/owner-managed by Managing Director Martin Flaška, with no disclosed external investors, parent company, or institutional funding.
