SUN PEAK

What SUN PEAK does

SUN PEAK (legal entity: SUN PEAK Unternehmensgruppe der Ratio Data GmbH) is a German turnkey solar installer headquartered in Hemsbach, Baden-Württemberg, in business since 2003 and operating as part of the Ratio Data GmbH corporate group under Managing Director Peter Doll. The company designs, supplies, and installs photovoltaic systems for residential homeowners (primary segment) and commercial/agricultural operators (secondary segment) in the German market, with all installation work performed by its own in-house roofers and electricians rather than subcontractors.

Its core product offering centers on rooftop photovoltaic systems combined with battery storage, offered through two main technology partnerships: SENEC (SENEC.P4 and SENEC.Home storage systems, with up to 4.2–17.75 kWh usable capacity, solar-optimized charging, peak shaving, and a 20-year warranty extension) and SolarEdge (Home Battery 48V, Hub inverters, and module-level power optimizers with backup capability). The product surface also includes the SENEC Wallbox for EV charging, Würth mounting structures, multiple PV module brands (QCELLS Q.PEAK DUO M-G11S+, Trina Vertex S, Meyer Burger glass-glass), and an own-branded SUN PEAK glass-glass module (430W). Supporting services include free on-site consultation (Vor-Ort-Beratung) using drone-based roof documentation and monitoring via the SENEC.App.

SUN PEAK makes money predominantly through one-time hardware sales and installation fees on each project (PV systems, battery storage, and EV chargers), with consulting and project management bundled into the installation quote. Pricing is not publicly disclosed and is determined individually per on-site consultation. The go-to-market is direct field sales, primarily through website lead capture, word-of-mouth referrals, and the free on-site consultation funnel, with no resellers or distribution partners used. Customer concentration is low by construction because the model is fragmented residential and small-commercial project work, though the company is geographically concentrated in the Hemsbach/Baden-Württemberg region.
