Top 5 Dutch solar software solutions in 2025

Imagine the ability to plan, design, and visualize a solar installation before even setting foot on the site. Sending automated emails to your clients without having to type them every time, or having your client sign your quotation online just after you send it. That's the power of software. In the fast-paced world of sustainable installations, using software designed specifically for your needs can be a game-changer.

However, like any technology, each software comes with its own set of pros and cons. That's why we've taken the time to analyze the Dutch market and create a list of the top 5 Dutch solar software solutions available in 2025.

In this blog post, we'll dive deep into each software, discussing their features and pricing to help you make an informed decision.

2Solar pricing

2Solar license costs vary by role. Admin licenses are the priciest, while viewing accounts, like those for installers, are the cheapest. Onboarding costs, calculated per user, are also important to consider. This pricing model benefits small companies with one admin role and several mechanics but can be costly for large businesses with many admins and additional roles. Prices can differ by country and company setup, so we suggest contacting the 2Solar team directly to find the best pricing for your business.

SolarMonkey

SolarMonkey has a strong presence in the Netherlands, Belgium, Germany, Spain, and the UK (since August 2023). It serves small businesses, mid-size businesses, and large enterprises.

SolarMonkey pricing

SolarMonkey uses a project-based payment method, making it easy to budget for each project individually. In the Dutch market, SolarMonkey charges €15 per quote or €150 for 10 quotes. This project-based pricing method allows businesses to pay only for what they use, making it a cost-effective solution for small companies. On the other hand, if you need to generate a lot of solar quotations, SolarMonkey might be a costly solution for you. In the Spanish market, the pricing is slightly lower at €14.50 per quote or €145 for 10 quotes, with the same project-based payment method.
