PV-integrated noise barriers for transportation corridors
U.S. startup Ko-Solar and Germany’s R. Kohlhauer, announced plans to offer turnkey PV-integrated noise barrier systems for transportation corridors, such as alongside highways, railways, and airport runways.
Planted Solar expanding terrain-conforming PV plant design platform
The U.S-startup with a land-use efficient, terrain-conforming PV plant design for solar developers said it will invest in expanding into Europe, and in further product development.
How long do residential solar panels last?
Several factors affect the productive lifespan of a residential solar panel. In the first part of a series, we look at the solar panels themselves.
LNG, solar collectors improve round-trip efficiency of LAES systems
Scientists simulated several liquid air energy storage systems, comparing round-trip efficiency across configurations that include liquefied natural gas (LNG), solar, and Stirling engines, and further optimized performance using particle swarm methods.

Novel MPPT method combines APO, model-predictive control
An international research team has tested a hybrid control technique combining adapted perturb and observe (APO) with model-predictive control to address complex partial shading in solar arrays. The method, validated through simulation and physical experiments, reportedly outperforms existing approaches.
Impact of hydrogen on silicon solar cell degradation
German researchers have reviewed recent studies on hydrogen-related degradation in silicon solar cells. They said the work is timely, with n-type silicon dominating production and antimony-doping emerging.
‘Soft-connected’ floating PV for offshore scenarios
An international research team has tested a floating PV system with a “soft-connected” configuration under offshore conditions, using six modular pontoons linked by elastic bar elements to simulate mooring lines and connection ropes.
