1KOMMA5&deg; was founded in summer 2021 by entrepreneurs and industry experts with the aim of making buildings holistically CO2 neutral through the use of photovoltaics, heat pumps and charging infrastructure. This is implemented by providing technology for decentralized, clean energy, mobility and heat supply. Thanks to the intelligent energy management &ldquo;Heartbeat&rdquo; and the dynamic electricity tariff &ldquo;Dynamic Pulse&rdquo;, 1KOMMA5&deg; always guarantees the cheapest and cleanest electricity from sun and wind. 1KOMMA5&deg; participates in particularly innovative craft businesses in the areas of photovoltaics, electricity storage, charging infrastructure and heat pumps, on the one hand to strengthen regional crafts and on the other hand to enable high-quality advice and installation at the customer's site. 1KOMMA5&deg; currently operates over 65 locations with around 1,500 employees from Europe to Australia. In addition, 1KOMMA5&deg; is working on networking and controlling decentralized generation systems with the aim of fully realizing the potential of the decentralized energy transition. For this purpose, all installed systems become part of a networked IoT platform, which uses algorithms to guarantee optimal, automatic operational management over the life of the system.
