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

Many existing installations still operate below their potential efficiency. Upgrading these systems offers a path to better performance, cost savings, and longer service life. The key to successful upgrades lies in smart energy management and thorough energy system valuation. This post explores practical strategies to enhance renewable energy systems efficiency, focusing on how energy professionals can apply energy management techniques to maximize output and value.

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.
