Snow can dramatically affect the performance of solar photovoltaic (PV) systems. In January 2026, a radical snow event blanketed many solar PV sites in northern Italy, offering a rare opportunity to study how heavy snow cover influences solar energy production. Using Soltell's Sensorless performance measurement and SysMap analytics, this event provided valuable insights into measuring soiling ratios under extreme conditions and improving analytics for operational responses to

A robust alternative to remote weather measurement is urgently required, mitigating the risks associated with weather satellite network degradation, upon the increasing risk of low-orbit space debree cascade event.

Among the latest advancements, Sensorless solar performance measurement has emerged as a promising approach to accurately measure the performance of rooftop solar installations without the complexity and expense of additional hardware sensors.

Businesses are looking for ways to optimize their operations and reduce costs. For commercial solar asset owners, one powerful approach is predictive maintenance. By leveraging advanced technologies, predictive maintenance not only enhances performance but also improves the overall financial health of solar installations.

Explore effective techniques to optimize rooftop solar inverters and ensure peak energy performance.

Soltell’s SysMap API V1.1 delivers Sensorless technology-powered, Orange Button-compliant solar performance data, designed for Energy Finance, SCADA & EMS platforms. One REST integration gives you real-time/historical production, modeled energy, availability, performance indexes, soiling losses, predictive O&M insights in any language, and full operating reports.

Rooftop solar PV systems are tightly coupled to the stability of the electricity grid. While most discussions focus on modules, soiling, shading, or inverter efficiency, one of the most influential factors on real-world performance is the condition of the local grid. Voltage, phase quality and even frequency determine whether a solar inverter can operate continuously or must disconnect for safety.

The issue of leakage in photovoltaic energy systems is controversial and you will find a large number of professional opinions on the subject. Some recommend completely ignoring the matter, while others do recommend monitoring the phenomenon and executing a systemic solution once every few years, and there are those who recommend treating the phenomenon as soon as possible - allocating the problematic component with the defective insulation. Who is right? Well - probably all
