What 4BLUE does
4BLUE B.V. is a Dutch B2B solar wholesaler founded on August 1, 2015 by a team of four entrepreneurs including Dennis and Robert-Paul Evers, operating from Andelst in the Netherlands after relocating from Nijmegen to accommodate growth. The company sells solar panels, inverters (string and micro), battery storage systems, mounting materials, AC/DC electrical components, air conditioning units, and EV charging stations exclusively to professional installation companies, with the only disclosed end-customer reference being ChargeUp for a peak-shaving energy storage project. Its technology core is a B2B e-commerce platform featuring a system configurator that builds a complete solar system (panels, batteries, distribution board) in five minutes, a quick-order CSV upload tool, a real-time inventory module, a battery decision tree, and a solar yield calculator, complemented by the 4blueprint project advisory service staffed by PV-engineers for SMB commercial installations.
Revenue is generated primarily through transaction-based hardware sales to registered business customers with credit limits, with order surcharges of €60 for orders under €2,500 and €75 transport fees for deliveries to installation sites; complementary revenue flows from the 4blueprint advisory service. 4BLUE operates a hybrid go-to-market combining inside sales, field account management, and product-led growth through self-service configurators. The team has grown to 50+ specialists, with partnerships spanning Enphase, Growatt, Huawei, Meyer Burger, URECO, Risen Energy, and Esdec/Enstall, plus a recycling partnership with Stichting OPEN. The company has received multiple FD Gazellen nominations and self-identifies as the fastest-growing solar wholesaler in the Netherlands.

4BLUE competitors and assessment
Company assessmentDirect peers
- Enerix: Franchise-based solar installer network in DACH with strong distribution and installer-enablement focus. Comparable to 4blue in target customer (installers) and emphasis on configurator-style project support.
- Krannich Solar: One of Europe's largest B2B solar wholesalers with a multi-country presence. Directly comparable to 4blue as a full-line PV distributor serving professional installers across panels, inverters, batteries, and mounting.
- Memodo: European B2B solar and storage distributor operating in DACH and beyond. Closely comparable to 4blue's model: multi-brand panel/inverter/battery wholesale, project services, and installer-focused tooling.
- IBC Solar: German-headquartered solar wholesaler and EPC operator with decades of distribution history. Comparable to 4blue as a multi-brand solar component distributor serving installers and project developers across Europe.
Broad incumbents
- BayWa r.e. Major European renewable energy group combining wholesale, project development, and services. Overlaps with 4blue as a solar component distributor but operates at much larger scale across a broader portfolio.
- Viessmann: Large German HVAC/heating incumbent that also distributes solar and storage to installers. Comparable to 4blue as an adjacent-category wholesaler using installer relationships, but at much greater scale and breadth.
Regional players
- Zelfstroom: Dutch solar installer and supplier focusing on the residential prosumer market. Comparable to 4blue's downstream customer profile and a regional counterpart in the Netherlands.
Others
- Enstall / Esdec: Mounting-systems manufacturer (Esdec/ClickFit Evo, FlatFix) that is both a 4blue supplier and a globally scaled competitor in PV mounting distribution. Relevant adjacency given shared installer channels.
