What Soltop Energie does

SOLTOP Energie AG is a Swiss privately held Aktiengesellschaft founded in 1973, headquartered in Elgg, Switzerland, that designs, manufactures, and distributes integrated renewable energy systems spanning photovoltaic modules, inverters, battery storage, electric vehicle wallboxes, heat pumps, ice/ground thermal storage, and the proprietary KIGO brand of radiant climate ceilings. Manufacturing is conducted at two Swiss facilities in Elgg and Sierre, with sales and service coverage in German- and French-speaking Switzerland, the European Union and Norway via a wholly-owned German subsidiary (SOLTOP Energie GmbH), and a recently established US sales representative position.

The company's technology stack centers on the patented KIGO copper heat exchanger (laser-welded copper tubes on rectangular perforated sheets) and a family of climate ceiling products (Standard, Flex, Copper, Zen) that claim up to 45% energy savings for heating and cooling, alongside Duraklick mounting systems and the Soltop Energy Master energy management system. Revenue is generated primarily through B2B distribution to professional installers (solar, roofing, electrical, heating contractors) and planners/architects, supplemented by direct B2C sales through the company website with online calculators, and an after-sales service operation across Switzerland.

Customer reference projects span marquee enterprise logos (Microsoft, UBS, AXA, Audemars Piguet, Aproz Mineralquellen) and public/commercial buildings (Bahnhof Siders, Musikzentrum Sion), while the primary volume base is distributed across residential and small-commercial projects via the installer channel. The company is led by CEO Wolfgang Thiele, CFO Thomas Habrik, and CHRO Sandra Robbiani, operates two wholly-owned regional subsidiaries, and holds active memberships across at least eight Swiss and one Swedish industry associations in solar, heat pumps, and building climate.

Core offering

Soltop Energie AG manufactures and distributes renewable energy hardware for residential and commercial buildings, including complete photovoltaic systems (modules, string and hybrid inverters, battery storage, wallboxes, mounting systems), heat pumps (air-water and brine-water), and the proprietary KIGO climate ceiling product family for radiant heating and cooling. The company also supplies integrated energy solutions such as ice and ground thermal storage (IceSol/EarthSol), heating system replacement services, and customer service support, sold primarily to professional installers, planners, and architects in Switzerland, the EU, and Norway.

Product overview

Soltop Energie AG is a Swiss renewable energy company established in 1973, serving as a reliable partner for solar installers, roofers, electrical and heating contractors, planners, and architects. The company operates as a single unified product portfolio rather than a platform-plus-modules architecture. Their offering spans five core product categories: (1) Photovoltaic systems with components including Energy-Wizard string inverters, Energy-Butler battery/hybrid inverters, Energy-Charger wallboxes, and Soltop Energy Master management systems, plus Duraklick mounting systems for flat roofs; (2) Heat pumps including air-water and brine-water systems with storage solutions; (3) KIGO climate ceilings (KIGO Standard, KIGO Flex, KIGO Copper, KIGO Zen Klimatop) for radiant heating and cooling with up to 45% energy savings; (4) Energy Solutions including IceSol ice storage, EarthSol ground storage, thermal collectors, and heating replacement; and (5) Customer service and EU/Norway sales operations. These products are networked into holistic energy solutions combining generation, storage, and intelligent management.
