The First Rays of Sunshine
Three TU Delft students huddled together in 2015, staring at a problem that had plagued the solar industry for years. Solar installers were working blind—guessing system yields, struggling with manual measurements, and making promises they couldn’t keep. This turned out to be the start of a solar software success story and guide.
What if there was a better way?

Design: Seeing the Impossible
Our journey began with a radical idea. What if we could create a tool that could see what no one else could? Imagine aerial imagery so precise, so detailed, that every roof became a canvas of potential. We developed software that can calculate yields with over 95% accuracy, transforming rough estimates into crystal-clear designs. And not only is it accurate, it’s also quick: you can create a full design in 90 seconds.
To this day we keep making sure that we maintain this accuracy, continuously monitoring over 25.000 systems and transforming the way you can design by introducing new features such as drone imagery & looking to the future with AI-enhanced imagery.
Sell: Turning Possibilities into Profits
However, we quickly learned that installers weren’t only struggling with designing accurate systems. Our next challenge was: How do you sell a system better than any other competitor?
The solar market is a competitive landscape. Installers were struggling to convince clients with generic quotes & complicated presentations, resulting in lost sales opportunities. We knew there had to be a smarter approach.
Our sales tool became the secret weapon solar installers never knew they needed. Suddenly, a time-consuming and difficult process of creating a proposal became a breeze. With the click of a button, installers were able to make personalised proposals in their own style that blew their prospects away and turned them into happy clients.
Conversion rates soared, with installers increasing their conversion rate by 24% on average. Installers started selling solar with ease & confidence.


Connect: Continuous Engagement
But we didn’t stop there. We discovered a hidden truth: a solar installation isn’t the end of a customer relationship—it’s the new beginning.
Heat pumps. EV chargers. Batteries. The modern homeowner wants more than just solar—they want a complete energy ecosystem. With our lead generation tool Connect+, we’ve created a way for installers to turn past customers into premium leads, to continue the conversation long after the first installation. And the best thing? You can use our proposals to finalise the deal as well.
