Powering your home using solar technology is not a bad idea. But you are going to need a way to keep your solar panels clean. Scrobby Solar happens to be a robot that keeps your solar panels clean for you. It does not require an external power or water supply as it uses rain and a brush to scrub your panels clean. You can also control it using a Bluetooth connection.
Users have the option to change the schedule for the robot using its companion app. The default setting covers 3 full cleans per year. You can get your very own Scrobby Solar kit for as low as €269. The idea is certainly interesting, but it will interesting to see how well it performs over time.
