GO SunPilot is your solar forecast app: it predicts precisely when your rooftop PV system or balcony solar plant will generate power – and when to run your washing machine, dishwasher or EV charger on free solar energy. Boost your self-consumption and cut electricity costs, no smart home hardware required.

You are standing in the kitchen, coffee steaming – and your phone shows you at a glance: today at 11 a.m. your solar system will produce enough power to run the washing machine and dishwasher at the same time, for free.
No more guessing. No more wasted solar power.
