What Solar Monkey does

Solar Monkey is a Netherlands-based B2B SaaS company that provides cloud-based design, calculation, and quotation software for renewable energy installers. Founded in 2015 by three engineers from TU Delft, the platform enables installers of solar PV systems, home batteries, heat pumps, EV chargers, and air conditioning to produce system designs in approximately 90 seconds, generate professional branded quotations with customizable templates, and run 25-year financial projections including self-consumption, self-sufficiency, and dynamic tariff scenarios. The company serves over 500 installation companies in the Netherlands and over 800 solar businesses across Europe, and following the March 2026 merger with Swiss company Eturnity, the combined entity serves 2,000+ installers across 8+ European countries.

The core technology is a cloud-based SaaS platform built by TU Delft engineers, featuring automated shading calculations, panel orientation analysis, five preset regional consumption profiles (Netherlands, Belgium, Germany, Spain, Italy), battery yield optimization using hourly time-series data (8,760 values per year), and Dynamic Rates modules for markets transitioning to dynamic energy contracts. The product portfolio includes the Core Software platform with PV Design and Battery Calculation modules as primary capabilities, plus add-on modules for Heat Pump, EV Charger, and Air Conditioning quotations, the Connect+ lead generation tool with branded landing pages, and Zonnegarant monitoring service that reads yield data from SolarEdge, Growatt, SMA, Solax, Goodwe, and Trannergy inverters via API. An open API and pre-built integrations with Pipedrive, Salesforce, Odoo, Zoho, HERO Software, BLOX, Splandid, OutSmart, MoreApp, and AirTeam embed the platform into installer operations across CRM, ERP, and field service workflows.

Solar Monkey operates a hybrid SaaS revenue model with a monthly subscription starting at €85 per month plus a usage-based €12 per project fee, distributed primarily through self-serve website signup with a 14-day free trial across country-specific domains (NL, UK, DE, ES, BE). The company is headquartered in Den Haag, Netherlands, and is backed by a European investor syndicate including Helen Ventures (Finland), Eneco Ventures (Netherlands), 4impact, InnovationQuarter, Klima (Spain), and Junction (Belgium). CEO and founder Jan Pieter Versluijs leads the company alongside CCO Annemarie de Jong.
