Problem
Homeowners in Germany face high heating and electricity costs, complex financing options, and fragmented installation services when trying to transition to renewable energy systems such as heat pumps and photovoltaic panels.
Solution
Enter acts as a full‑stack energy advisor and marketplace that guides homeowners through a complete retrofit process. The company first performs a detailed, whole‑house analysis—including heating load, building envelope, and consumption patterns—to determine the optimal size of a heat pump, solar PV system, battery storage, and smart energy manager. Based on this analysis, certified regional SHK master‑craftsmen install the precisely dimensioned equipment, while Enter secures the maximum available KfW and BAFA subsidies. An integrated software platform, Enter Connect, continuously optimizes operation by shifting loads to low‑price electricity periods and maximizing self‑consumption of solar generation. The service remains free until the homeowner decides to proceed, and includes a two‑year remote‑maintenance guarantee.
Target Audience
Primary customers are German single‑family homeowners and small residential property owners seeking to replace fossil heating with renewable systems and reduce their energy bills.
