The first ever solar panel cell was created more than eighty years ago: and like many other innovations, it was created by pure accident. Yet since then, those signature rectangular structures can be spotted on the roofs of houses and buildings all over the world. In fact, the number of US solar panel installations is 23 times higher today than in 2014. While this is a clear win for environmental sustainability, it remains near impossible to measure and manage one’s clean energy consumption with solar panels alone. And with more than a third of the world’s population calling apartment buildings home, many consumers lack easy access to clean energy altogether.
