This app allows investors of “We Share Solar”, a crowd-funding platform for collective solar power in the Netherlands, to constantly monitor the performance of their solar panels. An indicator makes it easy for users to check how much energy they are generating. A real-time connection with the shared solar panels shows the perform-ance at any particular moment, as well as daily, monthly, annual and total performance. These figures are then compared to the expected return, providing a transparent overview of how the investment is performing.
