Solar PV Panel Smart Box for safety, security and enhanced performance

The start-up

A remote switch that enables users to switch off each solar PV panel individually.

The need

The DC voltage in rooftop mounted PV panels can reach levels of up to 1000 V. In emergency situations, and in cases of faulty wiring, individuals, especially firefighters, can be exposed to dangerous levels of electricity. A further issue we address is the widespread theft of rooftop PV panels.

The solution

The SolAngel product enables solar panels to be disconnected from each other in an emergency situation automatically or at the request of the owner or of fire fighters.

The value proposition

Our solution cuts off the voltage at the panel level, which eliminates the risk of electrocution by reducing the voltage to a maximum of 50 V. Our solution is also more economical than other comparative solutions, such as optimisers or micro-inverters, which mostly compete in the new installations sector. Other features that will be incorporated, since they add little to no cost on the hardware, are an anti-theft function and panel monitoring.
