Qilowatt Solutions B.V.

What Qilowatt Solutions B.V. does

Qilowatt Solutions B.V. is a Dutch sustainable energy installer headquartered in Apeldoorn that designs, sells, and installs home batteries, solar panels, and solar water heaters for residential and business customers across the Netherlands. The product portfolio is anchored on battery storage systems from Huawei, AlphaESS, Enphase, and Sigenergy, paired with solar PV and solar thermal offerings, with batteries priced in a €3,495–€12,499 range and solar water heaters at €1,750–€2,250.

The company's commercial model is sales-led and direct-to-customer, supported by an in-house team of certified installers operating from a central Apeldoorn location. Customer acquisition addresses four segments: residential households (primary), SMB and MKB accounts, large enterprises, and institutional buyers including housing corporations and municipalities. Customer trust is supported by a 4.7/5 Trustpilot score, SGZE guarantee fund affiliation, and a VAT recovery service delivered through De Centrale to reduce purchase friction.

Qilowatt's principal differentiator versus a generic installer is the integration layer with energy markets. Through the NextEnergy Gateway and Frank Energie partnerships, installed battery systems can participate in FCR, aFRR, and intraday market trading as of April 2025, turning the battery from a passive self-consumption asset into an active grid-balancing revenue stream. The company is privately held with no disclosed funding rounds, no parent company, and a leadership team comprising General Director Maarten Versloot, Commercial Director Erik Braunius, and Technical Director Mike Brouwer.

Direct peers

• Frank Energie: Frank Energie is a Dutch dynamic energy contract provider whose app controls home batteries to trade on the imbalance, day-ahead, FCR, aFRR, and intraday markets. Overlaps directly with Qilowatt's energy-trading value proposition and is simultaneously a technology partner, making it the closest functional competitor in the trading-enabled battery segment.
• Zelfstroom: Zelfstroom is a Dutch residential solar and battery installer selling directly to Dutch homeowners with a similar sales-led, advisory-driven GTM. Highly comparable to Qilowatt in target customer, product mix (solar + home battery), and ownership/financing options.
• Tibber: Tibber is a digital dynamic-tariff energy retailer active in the Netherlands with smart-home energy management features and integrations with home batteries. Comparable to Qilowatt in dynamic-contract and energy-optimization positioning, though primarily a retailer rather than installer.
• Bink Solar: Bink Solar is a Dutch solar panel and home battery installer serving residential customers. Comparable to Qilowatt in target segment, product offering, and direct-to-consumer sales model in the Netherlands.
• EnergyZero: EnergyZero is a Dutch dynamic energy contract provider that offers variable hourly tariffs and is increasingly integrated with home energy storage. Comparable to Qilowatt in dynamic-tariff customer value proposition and battery-savings narrative.

Broad incumbents

• Pure Energie: Pure Energie is a Dutch green energy supplier offering dynamic tariffs and renewable supply to households. Comparable to Qilowatt in targeting cost-conscious green-energy Dutch consumers, but competes primarily on supply rather than hardware installation.
• Greenchoice: Greenchoice is a large Dutch green energy supplier with residential and SMB offerings across supply, solar, and increasingly storage. Comparable to Qilowatt at the customer and value-proposition level (green energy, self-generation, cost reduction) but operates at much larger scale and as a broad incumbent.
• Vattenfall: Vattenfall is a major European energy company with a Dutch retail business offering supply and solar/battery solutions. Comparable to Qilowatt in serving Dutch residential and SMB customers with renewable energy offerings, but as a broad incumbent.
• Eneco: Eneco is one of the largest Dutch energy companies offering supply, solar, heat pumps, and increasingly home battery solutions to residential and business customers. Comparable to Qilowatt in customer base and product direction, but as a broad incumbent with much greater resources.

Others

• NextEnergy: NextEnergy is a Dutch energy company that provides dynamic energy contracts and the NextEnergy Gateway used to trade on multiple energy markets. Not a direct competitor to Qilowatt but a critical technology partner and adjacent infrastructure provider in the same energy-trading ecosystem.
