What we do?
How do we measure whether a Solar Photovoltaic (PV) system performs well? Can Solar PV sites be assigned a health rating and what is their future performance? We answer this with Senorless PV performance measurement, integrating with energy platforms and delivering industrial automation. We also design interoperability solutions for decentralized energy management: PV, Battery ESS & EV.
Technology
Soltell's Sensorless technology is a state-of-the-art tool for assessing PV performance indicators (energy, power and soiling indices) at superb accuracy, developed with the support of the Israel Innovation Authority. This low-cost, high-accuracy smart alternative to meteorological stations and remote sensing solutions utilizes site's electrical sensor data to extrapolate localized irradiance and temperature conditions.
