What Energieversum does

Energieversum is a German full-service photovoltaic (PV) system integrator founded in 2010 and headquartered in Steinhagen, Germany, operating as a subsidiary of EnBW Energie Baden-Württemberg AG — Germany's second-largest energy company with approximately 30,000 employees and over 90% public ownership. The company provides all-inclusive fixed-price solar packages to German residential and commercial customers, bundling solar modules, lithium iron phosphate (LFP) battery storage (including the proprietary EV.longlifeakku co-developed with Fox ESS with 10,000 guaranteed cycles and a 20-year warranty), hybrid inverters, the EV.cockpit home energy management system (HEMS, co-developed with Schneider Electric), EV wallboxes, heat pumps (heatrex Giant and Silence), and backup power systems into turnkey solutions. The company claims more than 50,000 residential customers, 528,000+ mounted PV modules, 20,000+ installed battery storage systems, and 250+ commercial/industrial projects.

The business model combines one-time revenue from PV installation sales (residential battery storage systems priced at €8,000-€11,000; small commercial installations at €900-€1,100/kWp; and solar parks at €600,000-€900,000 per MWp) with recurring revenue from a dynamic electricity tariff (claiming up to 35% savings vs. standard tariffs), PV insurance products including EV.protect with 20-year coverage, and PV financing facilitation. Pricing is delivered through individualized consultations rather than public e-commerce; a 4-month commissioning guarantee is included in the all-inclusive package.

Go-to-market is built on a direct field sales force of regional solar advisors (Fachberater) who conduct on-site feasibility assessments, supported by a Germany-wide network of certified specialist installation partners (Fachpartner) and Montageteams. Customer acquisition flows through website consultation booking, Google and ProvenExpert reviews, word-of-mouth referrals, and a partner network. The company serves three primary segments: residential homeowners (single-family and multi-family buildings), commercial and industrial customers (ranging from 30 kWp small commercial to multi-MW solar parks), and large commercial properties (shopping centers, hotels, clinics requiring industrial heat pumps). Operations are entirely domestic within Germany.

Revenue model

1. Photovoltaik Komplettpakete: Energieversum generates the majority of its revenue from selling all-inclusive photovoltaic systems as fixed-price packages. These include solar modules, inverters, mounting hardware, installation, and commissioning. Pricing is determined by system size, components selected, and roof complexity. The company guarantees operation within four months of order confirmation.
2. Batteriespeicher (EV.longlifeakku & SENEC): Sale of battery storage systems including the proprietary EV.longlifeakku (LFP, 7.52–26.32 kWh, 20-year warranty) and SENEC storage systems. Storage systems can be purchased as part of a new PV installation or retrofitted to existing solar installations.
3. Wallbox & EV-Ladetechnik: Revenue from selling and installing wallbox charging stations including the proprietary EV Charger 11 kW, SENEC.Wallbox (11/22 kW), Schneider Electric Charge 11/22, and AlphaESS SMILE. Solar-optimized charging is a key selling point for EV-owning households.
4. Wärmepumpen (Gewerbe & Privat): Energieversum acts as an intermediary for commercial heat pump sales and installation through its partner heatrex. Products include the heatrex Giant (for commercial properties over 1,000 m²) and heatrex Silence (residential). The company facilitates the sale while heatrex handles delivery, installation, and commissioning.
5. Gewerbe PV-Lösungen: Comprehensive commercial and industrial PV solutions including rooftop installations (flat and pitched roofs), ground-mounted solar farms (Freiflächenanlagen), commercial battery storage, and heat pump integration. Commercial projects range from 30–100 kWp small commercial to multi-MW installations. Revenue derived from large-scale system sales and project management fees.
6. Dynamischer Stromtarif: Energieversum offers a dynamic electricity tariff through a comparison portal, enabling households to purchase electricity at hourly market rates. Claims up to 35% savings versus standard tariffs, using 100% green electricity. Revenue generated through electricity supply contracts with consumers.
7. PV-Versicherung & EV.protect: Optional insurance products including EV.protect covering follow-up costs for up to 20 years, providing financial protection for the PV investment. Also offers PV insurance policies bundled with the all-in packages.
8. Photovoltaik-Kredit: Energieversum facilitates financing for PV installations through a photovoltaic credit partnership, offering favorable terms for customers to finance their solar investments.
