Fraunhofer ISE, PTB report just 0.15% uncertainty in PV module yield measurements
An interlaboratory comparison between the CalLab PV Modules of Fraunhofer Institute for Solar Energy Systems ISE and Physikalisch-Technische Bundesanstalt finds the two organizations deviate by less than 0.15% when measuring the performance of photovoltaic modules. The Fraunhofer team says this is one of the most important indications as to whether their analysis is on the right track.
Mibet launches universal metal roof mounting system
The Chinese supplier said the new product uses high-strength AL6005-T5 aluminum alloy and SUS304 stainless steel. It can be adjusted to a tilt angle of 0-15°.
IEC-based technical specifications needed for second-life PV module market
The latest report from the International Energy Agency’s (IEA) Photovoltaic Power Systems Programme (PVPS) says second-life PV modules have the potential to reduce waste and extend the value of solar assets, but their market today remains underdeveloped and requires advances in technical qualifications, scalable reuse infrastructure and supportive policy frameworks.
SALD launches large area sheet-to-sheet tool for perovskite solar pilot lines
The Dutch spatial atomic layer deposition equipment manufacturer has launched a new sheet-to-sheet tool for pilot production of large area perovskite solar devices on glass substrates.
UV testing, solar cell factory inspection now mandatory for Munich Re’s PV warranty insurance
The world’s largest reinsurer has recently introduced stricter requirements for PV warranty insurance to further de-risk insured PV parks and set a higher benchmark for industry wide reliability and production quality.
Agrivoltaics? Yes in my vineyard
Researchers in Spain surveyed 238 wine tourists in the Murcia region and found broad support for trellis-integrated agrivoltaics in vineyards, with 94% backing solar integration and most respondents seeing no landscape conflict.
Comparing safety profiles of lithium-ion, sodium-ion and solid-state batteries
New research finds that battery safety rankings are not universal but highly dependent on application scenarios, and shows that LFP batteries can emit high levels of hydrogen fluoride, challenging their reputation as the “safest” chemistry.
SolarEdge ships US-made inverters to Europe, ramping up BESS manufacturing
Single-phase inverter products manufactured in Texas are now being shipped to multiple European markets as SolarEdge adapts its international export strategy. The manufacturer tells pv magazine key components will increasingly be manufactured in the United States in the coming years.
Scientists say land-preservation costs should be factored into agrivoltaics’ LCOE calculations
German researchers found that agrivoltaics costs far exceed agricultural benefits, raising doubts about subsidies and highlighting the need for more cost-competitive system designs.
New reflective coating increases BIPV power output by 11%
Australian researchers developed a low-cost reflective coating for semi-transparent solar roof tiles that lowers surface temperatures by up to 20 C and boosts power output by up to 11.7%. Simulations across five global cities showed energy savings of up to 5.85%, highlighting the coating’s strong potential for improving both building cooling efficiency and solar performance in BIPV systems.
