This French Start-up Mixes Wind and Solar Energy In A Single Unit

Unéole’s energy system combines a photovoltaic rooftop panel with 2 compact wind turbines, generating 40% more energy than an ordinary rooftop panel. Solar panels work best in strong sunlight but Unéole’s units generate power when it’s overcast or during winter and can turn through the night to ensure a steady flow of power. The turbines are silent, so they don’t disturb building occupants and they’re built from mostly recycled aluminium and steel.
