Lightricity

Lightricity manufactures and sells the world’s most efficient indoor PV technology (though it works excellently outdoors, too). It converts indoor light to energy with up to 35% efficiency – a more than six-fold improvement on conventional PV. A panel the size of a fingertip will power an IoT device forever. Even in extremely low indoor light, opening possibilities to power IoT devices not previously thought possible with indoor light. We offer two solutions. For those designing new connected devices, our customisable PV panels can be integrated into any low-power IoT device as an alternative to primary batteries. For IoT systems integrators, we offer off-the-shelf, easy-to-integrate, completely maintenance-free PV-powered sensors for many common measurement and tracking applications.
