Wattco

What Wattco does

Wattco is a privately held Dutch solar PV installation company founded in 2007 and headquartered in Maasdijk, in the Westland region of the Netherlands. The company designs, installs, and maintains photovoltaic systems for two primary customer segments: homeowners (Particulier) seeking residential energy independence and cost reduction, and businesses (Zakelijk) including commercial enterprises, homeowner associations (VvE), greenhouse operators, and infrastructure-related clients. Beyond standard rooftop PV, Wattco develops niche specializations including facade panels, carports with integrated EV charging, weak-roof mounting systems, and Hortisolar greenhouse-integrated panels that replace flat glass in greenhouse roofs.

Wattco's technical approach is anchored in Enphase micro-inverter architecture rather than traditional string inverters, providing per-panel optimization, built-in safety through low-voltage operation, and panel-level monitoring through the Enlighten app. All installations are performed by in-house mounting teams with more than 12 years of experience, and the company holds ISO 9001:2015 TUV quality and VCA safety certifications, alongside Enphase Platinum Partner status. Energy storage capability is delivered through sister company Battco, providing home battery and Energy Management System integration that positions the company ahead of the planned phase-out of the Dutch salderingsregeling net metering scheme in January 2027.

The business operates on a sales-led motion using a three-step process of free consultation, custom quote, and certified installation. Revenue is generated primarily through one-time hardware sales combined with installation labor for residential customers, supplemented by EV charging infrastructure and energy storage hardware, and by custom engineering services for complex commercial projects. Pricing is fully quote-based and not publicly disclosed; distribution is direct, combining inside sales for SMB and residential customers with field sales for enterprise projects, all concentrated within the Westland regional market.
