Technology and R&D

The Chinese manufacturer said its new OG02 series includes IP-65-rated inverters with an AC output power of 3 kW to 6 kW. The new products also feature a maximum efficiency of 97.6% and a European efficiency of 96.5%.

The Chinese manufacturer said it developed a new circuit-model–based method to accurately detect hot-spot risks in TOPCon back-contact modules, overcoming limitations of the IEC 61215 approach caused by low shunt resistance. Validated through indoor and outdoor tests, the method predicts temperature rise under shading and reportedly enables faster, more accurate hot-spot risk assessment.

New research from Italy has shown that agrivoltaic systems can reduce potato yield by up to 15% compared to full-light cropping. However, moderate early-season shading was found to delay soil-moisture depletion, extending biomass accumulation and improving water-use efficiency.

Under the terms of the agreement, Aiko will be licensed to Maxeon’s back-contact solar cell and module patents outside the U.S., while both companies drop all ongoing legal actions.

The European Network of Transmission System Operators for Electricity published a report on instability detection technologies to help countries with high renewable energy shares maintain grid reliability. The study highlights key tools, research priorities, and the need for stakeholder collaboration to advance real-time monitoring and data-driven decision-making.

Researchers in the Netherlands developed a model to identify tolerable degradation rates of the top cell in perovskite-silicon tandem modules. Simulations showed that an increase in tandem module efficiency from 28.0% to 32.9% could raise the tolerable degradation rate by approximately 50%.

An international study finds that successful agrivoltaic projects require farm-specific, holistic co-design that integrates PV layout with agricultural mechanization from the earliest planning stages. Without proper alignment between machinery, crops, and PV systems, agrivoltaics risk major land loss, lower field efficiency, and higher operating costs, undermining farm profitability.

Copec, Luxmeter Energy, and Ventisqueros have commissioned a system at the Quintupeu salmon farming center in Hornopirén, a remote area of southern Chile. The installation features a 48 kW photovoltaic plant paired with a 109 kWh battery storage system, enabling the facility to reduce its reliance on diesel generators in this off-grid aquaculture operation.

The multi-project cluster includes the world’s largest single-site electrochemical energy storage facility: the 4 GWh Envision Jingyi Chagan Hada Energy Storage Power Station.

Swiss startup Sun-Ways is testing removable solar panels installed on an operational railway line through a pilot project with French railway operator SNCF in Switzerland.
