What Krone Sonne does
Krone Sonne GmbH is an Austrian residential photovoltaic solutions provider headquartered in Mattersburg, operating as part of the Bessere Energie group affiliated with Burgenland Energie AG. The company sells complete PV packages to Austrian homeowners, bundling modules, inverters, mounting hardware, installation, grid connection administration, and EAG federal subsidy processing into a single offering. Its product portfolio spans two hardware tiers — Krone PV PLUS, a premium line built on Austrian-made Fronius GEN24 hybrid inverters and Fronius Reserva lithium iron phosphate batteries, and Krone PV PUR, a cost-efficient line using Fox ESS inverters — both carrying 10-year manufacturer warranties. System sizes range from 3 kWp to 10 kWp, with optional battery storage (6.3–12.6 kWh), full 3-phase PV-Backup+ emergency power, Smart Wallbox+ EV charging (up to 11 kW), and the Ohmpilot+ heating controller.
The company generates revenue primarily through one-time hardware sales with optional in-house installment financing (Ratenkauf), complemented by subscription income from the EnergIQ Plus energy management app (€4.99/month), a €99 on-site SonnenCheck analysis (refunded on order), and multi-year maintenance packages covering the 5th and 10th operating years. Go-to-market is a hybrid of product-led (online PV planner at kronesonne.at), sales-assisted (phone, email, on-site consultation), and channel-based (regional specialist installers across Austria), supported by a €150-per-side referral program and digital marketing. EnergIQ, operated on backend infrastructure provided by Zerofy OÜ, integrates with Fronius, BYD, Huawei, Shelly, MyStrom, and Sensibo devices for tariff-aware energy optimization.
Krone Sonne serves a long tail of Austrian residential homeowners as its primary customer base, having completed over 4,000 installations nationwide, and is extending into the commercial SME segment via a dedicated Business PV offering. It is a privately held company with managing directors Dr. Rainer Matiasek and Dr. Anja Schmidt, and is not publicly traded.
