Klarsolar

What Klarsolar does

Klarsolar (legal entity: klarsolar GmbH) is a German full-service residential photovoltaic (PV) provider founded in 2018 in Heidelberg by Bastian Arend and Dejan Durdic. The company offers consulting, configuration, planning, and installation of solar systems for private homeowners across Germany, anchored by three packaged offerings — Solar Basis Paket (from €8,799), Solar Komplett Paket (from €11,999), and Solar Autarkie Paket (from €16,999) — each bundled with the E.ON Home Energiemanager for intelligent energy management. Operations are supported by a proprietary digital sales-and-processing platform called "Klara," the Odoo Enterprise ERP system, and a recent Aurora Solar integration for live solar design and grid-registration planning.

The business operates a hybrid go-to-market combining a self-service online configurator (konfigurator.klarsolar.de), a customer portal (my.klarsolar.de), regional field sales (Außendienst) covering 16+ German territories, an independent craftsman partner network (Handwerkspartner) for installation execution, and recruited commercial agents (Handelsvertreter, §84 HGB). Revenue is generated primarily through one-time hardware sales of PV systems including panels, inverters, battery storage, wallboxes, and heat pumps, supplemented by installation and professional services, partner commissions, and recurring post-sale energy products (E.ON dynamic electricity tariffs, Energiemanager subscriptions).

Since December 2023, Klarsolar has been a 100% subsidiary of E.ON Energie Deutschland GmbH, providing balance-sheet backing, brand credibility, and access to E.ON's energy product suite. The company has served over 10,000 residential customers, holds a 4.3-star Google rating across 964 reviews, and was recognized on the Financial Times' Europe Fastest Growing Companies list. Current stated headcount is 101–250 with a publicly stated target of 1,000+ employees by 2025 and 50+ active job openings, signaling an aggressive scale-up phase under E.ON ownership.
