A Self‐Supervised Machine Learning Approach for the Estimation of Open‐Circuit Voltage Degradation in Photovoltaic Systems

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 920-941, July 2026.
This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage ( voc) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets. Results across three PV installations

L’evoluzione delle Stazioni Totali: quarant’anni di innovazione Topcon

GEOmedia, 2018
A 40-year history, from the introduction of the first total station model, so named because it introduced an absolute innovation compared to the combination theodolite-EDM, up to the last generations of robotic instrumentation for which the involvement of operator is reduced to the minimum terms.

Sustainable Photovoltaics: Optimising Material Consumption, Cost and Environmental Performance Through Smart Sustainability Approaches for Crystalline Silicon Solar Photovoltaics

Solar RRL, Volume 10, Issue 11, 15 June 2026.
A sustainability framework shows that photovoltaics can simultaneously improve material security, reduce costs, and improve environmental performance. Updated learning curves reveal declining material intensity and emissions alongside rising energy return on investment, EROI (> 25).

The Path to Future‐Proof Photovoltaics in Europe: Current Status and Impact of Technological Innovation on Reliable and Bankable Photovoltaics

Advanced Energy and Sustainability Research, Volume 7, Issue 6, June 2026.
This article provides an overview of the current state of the art and future improvements in PV technology and explains how changes in the technology and design of individual PV components—at the module level, the balance‐of‐system (BOS) level, or the PV plant level—can affect the reliability, durability, and energy output of a PV system.

Validation of a portable near‐infrared reflectance spectrometer to determine harvest maturity in grass seed crops

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Seed moisture content (SMC) is the most reliable indicator of seed maturity and the optimal harvest timing in grass seed crops. Current SMC testing methodologies used in grass seed crops are slow or inaccurate, making it difficult to make timely harvest decisions.
