This project is about how to save money with solar panels on your roof. The user is able to configure its own house with solar panels. On a map you can choose the position of your residence, your type of roof and its rotation towards the sun. The application calculates how much energy the solar panels could generate and when your investment would be payed off. To get a special discount it is possible to involve more houses in the same street in the same contract. All the necessary arrangements can be done online. This project was a cooperation between Info.nl and Edenspiekermann – I joined this agile project as the lead designer.
