SUNLUX

What SUNLUX does

SUNLUX s.r.o. is a Czech photovoltaic (FVE) engineering, procurement, and construction (EPC) company headquartered in Brno with operations in Kuřim, founded in 2009. The company designs, installs, commissions, and services turnkey solar energy systems for three customer segments: residential (rodinné domy), commercial and industrial firms (firmy), and public institutions, primarily across the Moravia region of the Czech Republic. Its core technology stack combines solar panels (AIKO, Canadian Solar, AEG, München Solar), inverters (Fronius, GoodWe, SolaX, Victron), battery energy storage systems up to 783+ kWh (SolaX Trene, Alpha ESS), Tigo panel-level optimizers for fire safety and partial-shading mitigation, and Infigy 2.0 / Infigy Play smart energy management platforms for remote monitoring and spot-price optimization. SUNLUX also delivers ČMI-certified electricity meter replacement for green-bonus installations and EV charging integration (GoodWe wallboxes).

The business operates on a direct-sales, quote-based model with no published pricing. Revenue is generated primarily through one-time turnkey installation contracts, supplemented by professional services revenue from technical audits (thermography with FLUKE cameras, I-V curve measurement with METREL), maintenance, ČMI-certified meter replacement, and community energy advisory under the KOMUNERG program. Go-to-market is direct via website inquiry forms and phone, with no resellers or distributors. SUNLUX differentiates through 15+ years of operating history, multiple OEM certifications (Fronius Service Partner, GoodWe PLUS+ Installer, Tigo Certified Installer, TIČR authorization), CAFT industry association membership, in-house custom switchgear manufacturing, and post-warranty servicing of both its own and competitor installations.

Scale indicators3 records

Recent moves5 records

Expansion highlights3 records

Broad incumbents

• Sonnen GmbH: German battery storage specialist (owned by Shell) providing residential and small commercial BESS systems with smart energy management. SUNLUX integrates similar BESS solutions (SolaX Trene, Alpha ESS) and offers equivalent energy management functionality through Infigy.
• Fronius International: Austrian-headquartered global manufacturer of solar inverters, welding, and battery charging technology. SUNLUX is a Fronius Service Partner and integrates Fronius inverters across its installations; Fronius is a broader incumbent with both overlapping installer network support and its own solar energy business unit.
• IBC Solar: German solar PV system integrator and wholesaler serving installers and large-scale projects across Europe. Comparable to SUNLUX as a PV system provider, but operates at significantly larger scale and broader geographic footprint including utility-scale project development.
• Solarwatt: German manufacturer of solar glass-glass modules and provider of complete PV systems including battery storage and energy management. Comparable offering to SUNLUX's turnkey residential and C&I solution, with stronger brand recognition across Europe and own module manufacturing.
• SolaX Power: China-headquartered manufacturer of hybrid inverters and battery storage systems (including the Trene large-capacity storage line used by SUNLUX). A core technology partner whose products underpin much of SUNLUX's BESS offering.

Emerging players

• Enphase Energy: US-based global supplier of microinverters and battery storage with strong European installer network. Competes in the same module-level power electronics and energy management category as SUNLUX's Tigo-optimized installations.
• Tigo Energy: US-based module-level power electronics provider whose optimizers SUNLUX installs as a Certified Tigo Installer. Provides enabling technology that differentiates SUNLUX's PV installations against non-optimized competitors.
• SolarEdge Technologies: Israeli-headquartered global leader in DC-optimized inverter and module-level power electronics for solar. SUNLUX uses Tigo for similar panel-level optimization; SolarEdge is a relevant technology peer whose ecosystem overlaps with SUNLUX's installer offering.

Direct peers

• Photon Energy: Amsterdam-listed solar PV developer and installer with deep Czech/Central European roots, offering turnkey utility-scale and C&I photovoltaic solutions. Directly comparable to SUNLUX as a turnkey solar PV provider in the Czech market, though operating at materially larger scale across multiple geographies.
• GreenTech Czech Republic: Czech renewable energy and solar PV installer operating in the domestic market across residential, commercial, and utility segments. Comparable regional peer competing for the same Czech customer base served by SUNLUX.
