Expert Solar Systems

What Expert Solar Systems does

Expert Solar Systems is a privately held Dutch solar installer founded in 2018 by René Westerheijden and headquartered in Purmerend. The company sells and installs complete photovoltaic (PV) systems for residential homeowners and small commercial customers across the Netherlands, with a stated service area covering every Dutch province and municipality. Pricing is published per system size (6-12 panel configurations with publicly disclosed prices ranging from approximately €3,200 for a basic GoodWe inverter package to roughly €6,200 for a premium Enphase micro-inverter package, all on glass-glass panels), indicating a transactional residential model.

The product architecture is a modular solar system built around Tier-1 glass-glass panels (Solarwatt, Hannover Solar, AEG, Exasun/Wienerberger Wevolt) paired with inverter solutions from SolarEdge (with per-panel optimizers), Enphase (per-panel micro-inverters), or GoodWe (basic 1-phase string). The company also offers Triple Solar PVT panels for combined electricity and heat generation, accessories such as Bird Blocker, and ancillary services including solar panel disassembly/reinstallation coordinated with Ruiter Dakkapellen and broader home sustainability work such as roof renovation and insulation.

Go-to-market is sales-led and direct-to-consumer: free in-home advisory consultations, customized quotes, and a typical 3-week installation timeline. Acquisition channels include the company website (content marketing, FAQ), LinkedIn, Trustpilot reviews, and customer referrals (with referral bonuses). Revenue mechanics combine one-time hardware sales (panels, inverters, mounting materials) and professional services (installation, disassembly/reinstallation, ancillary home-sustainability work); multi-year warranty handling is positioned as a service differentiator. The company is a member of the Holland Solar trade association and operates as the AEG Authorized Platinum Reseller via BonGo Solar.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Zelfstroom: Dutch residential solar specialist offering consultation, installation, and after-service to homeowners. Direct competitor with comparable go-to-market including in-home advisory and nationwide Dutch coverage.
• Solar.nl: Large Dutch residential and small-commercial solar installer operating nationally with a similar panel-plus-inverter-plus-installation offering. Competes head-on with Expert Solar Systems for the same Dutch homeowner segment.
• Zonneplan: One of the largest Dutch residential solar installers serving homeowners nationwide with bundled PV, battery, and heat-pump solutions. Directly comparable customer base, product mix, and geographic focus to Expert Solar Systems, but at materially greater scale.

Regional players

• Budgetcheck (Energie): Dutch energy comparison and switching service that also facilitates residential solar installations through partner installers in the Netherlands. Comparable customer intent (Dutch homeowners shopping solar) though primarily a marketplace lead-gen model rather than direct installer.

Broad incumbents

• Vandebron: Dutch energy supplier that has moved into distributed solar generation offerings for households. Comparable in customer relationship (Dutch residential energy consumer) but bundles solar within a larger energy supply business.
• Coolblue: Large Dutch omnichannel retailer that has expanded into residential solar installation alongside its core electronics business. Adjacent/overlapping offering to Expert Solar Systems but bundled within a much broader retail brand and operations.
• Sungevity: Historically significant European residential solar installer with operations in the Netherlands. Targets the same Dutch residential PV segment but as part of a multi-country footprint and historically larger marketing-driven acquisition model.
• Eneco: Major Dutch energy utility that offers residential solar installation and rental products alongside electricity and gas supply. Overlaps with Expert Solar Systems' Dutch homeowner segment but operates at vastly larger scale across multiple energy products.
