SolarEdge has released new optimizers for residential PV applications with a DC power rating of 500 W, a maximum efficiency of 99.5%, and a weighted efficiency of 98.6%. The optimizer for commercial and industrial applications offers 1.4 kW of rated DC power.

The extent to which PV-powered vehicles contribute to a reduction of CO2 emissions depends on variables such as the carbon intensity of the local grid, driving patterns, and solar irradiation. The market introduction requires technical optimization of the PV, but also of the vehicles.

The German PV testing equipment provider said its new Sinus-3000 Pro line is an ‘all-in-one system’ that can perform power measurements, bypass diode testing, insulation testing, visual inspection, and electroluminescence measurements. It is also offering the Sinus-3000 Advanced line for the testing of perovskite-silicon tandem, multi-junction and other new material cells.

Recom is offering five versions of its new all-black panels, with power outputs ranging from 440 W to 460 W and efficiency ratings of 22.5% to 23.6%. They feature 108 half-cut monocrystalline cells with n-type and back-contact technology.

Hurtigruten Norway. a cruise ship operator, said its new wind-solar-powered cruise vessel will be ready in 2030. It will have a storage capacity of 60 MWh.

Renac Power’s new all-in-one energy storage system for commercial and industrial (C&I) applications features a 110.6 kWh lithium iron phosphate (LFP) battery system with a 50 kW inverter.

A Chinese research team has fabricated an all-perovskite solar cell with a 3D/3D double-layer perovskite heterostructure that reportedly ensures improved charge extraction. The device achieved an open-circuit voltage of 2.112 V, a short-circuit current of 6.5 mA cm-2, and a remarkable fill factor of 81.9%.

US-based Runhood has introduced a modular battery design that directly connects to a portable solar array, so it can be quickly swapped in and out of the power bank for off-grid flexibility.

AEG is offering three versions of its new all-black panels, with power outputs of 420 W to 430 W and efficiency ratings ranging from 21.5% to 22.0%. They feature 108 half-cut monocrystalline cells with n-type technology.

Sunways’ new three-phase hybrid inverters have efficiency ratings of up to 98.2% and European efficiency ratings of 97.4%. They are available in seven versions, with power outputs ranging from 15 kW to 33 kW.
