Solarcheck24

Solarcheck24 is a German photovoltaics company based in Aachen, North Rhine-Westphalia, that positions itself as a regional PV specialist for homeowners. According to its own description, the company plans, supplies and installs turnkey solar systems with battery storage for single-family homeowners, with a focus on Cologne and its surrounding area — including Leverkusen, Hürth, Bergheim, Dormagen, Euskirchen and Troisdorf — as well as across the wider state of North Rhine-Westphalia. Its website markets the company under the tagline "Ihre PV-Profis aus dem Rheinland" (your PV professionals from the Rhineland). The company's core offer is a complete package: solar modules, a battery storage unit, an inverter, installation and grid registration. Its homepage advertises three complete packages, each including 10 kWp of solar modules, a 10–11.8 kWh battery storage unit, an inverter, installation and registration. The cheapest advertised package, the "Felicity" package, is listed at €12,999 including installation and grid operator registration, with 22 JA Solar 450 W modules and an 11.8 kWh storage unit. Solarcheck24 emphasizes fixed-price guarantees, €0 down payment, and installation by its own employed installation teams rather than subcontractors. A distinguishing feature of the company's sales process is its 3D solar planner, which lets prospective customers enter an address, mark their roof and place modules to receive an immediate PV plan including an energy yield and profitability calculation, free of charge and without registration. After that, a consultant visits the customer's home for a free on-site appointment, checks the roof and meter cabinet, and prepares a binding fixed-price offer — usually on the same day. The company states that installation of a single-family home is typically completed in one day, and that grid registration and commissioning are included. Solarcheck24 highlights manufacturer partnerships and system partnerships, and its website references KfW funding and 0% VAT eligibility. It also promotes the fact that feed-in tariffs end in 2026, urging customers to commission systems by 31 December 2026 to secure 7.78 ct/kWh for 20 years. The company describes itself as using JA Solar modules (full-black, glass-glass), hybrid inverters and battery storage, with manufacturer warranties of 12 years product / 25 years performance for modules, 10 years for inverters and 10–12 years for storage. As a regional installer, Solarcheck24 competes in Germany's residential solar market, where demand has been shaped by feed-in tariff deadlines, VAT exemptions and KfW funding programs. The company's emphasis on in-house installation teams, fixed pricing and a digital planning tool reflects common differentiators in this market. Its exact founding year, ownership structure and executive leadership are not specified in the available evidence.
