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 Sensorless PV performance measurement, integrating with energy platforms and delivering industrial automation. We also design interoperability solutions for decentralized energy management: Solar PV, Battery ESS & EV Charging.
High-accuracy Solar PV Performance assessment
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.

Advantages
Industrial IoT-powered Sensorless technology delivers 94-98% accuracy in solar PV performance assessment. Embedded in the SysMap solution, it enables financial risk management, monitoring automation and predictive maintenance (assessing degradation, soiling accumulation, grid disturbances, current leakage, etc.) - saving 90% in operations, 40% in maintenance, and cutting PV downtime by 65%. Coupled with high-accuracy solar PV forecasting, it optimizes energy management, increasing average site revenue by 3-7%.
