An international research team has presented all possible system designs and applications for photovoltaic-thermal (PVT) technology. Their review includes conventional PV-T collectors, air-based systems, liquid-based installations, water-based collectors, refrigerant-based systems, heat-pipe-based technologies, dual air-water systems, building-integrated PVT arrays, and concentrated PVT collectors.

LG has developed a new energy storage system for the US residential market that combines two 10-hour batteries or 16-hour Prime battery modules in parallel, providing 19.2 kWh to 32 kWh of capacity and a maximum 9.6 kW output from the inverter.

The Turkish authorities have set a 10-year feed-in tariff (FIT) of TRY 1.06 ($0.0545)/kWh for PV systems that are installed between July 1, 2021, and December 31, 2030. Solar projects with Turkish PV components will be given an additional five-year tariff of TRY 0.2880/kWh.

India’s Jakson says its new lithium battery inverter offering consists of a 3 kW battery energy storage system with a 3 kW hybrid inverter and a 4.8 kWh, 48V lithium-ion battery module. It can be expanded to megawatt scale, depending on power backup requirements.

California is looking to implement fixed monthly charges on utility bills, but the potential impact on residential solar remains unclear.

Record solar generation from large-scale and rooftop PV is driving down the wholesale cost of energy, reducing emissions to record lows, and helping to set new records for minimum demand for electricity from the grid, according to the Australian Energy Market Operator (AEMO).

Badenova has installed 912 glass-glass PV modules along a cycling path in the city of Freiburg, Germany, as part of a new pilot project.

Beny Electric’s new 600 W microinverters are designed for balcony solar modules, with a 96.5% efficiency rating and a European efficiency of 96%. They are available in three versions, with outputs of 500 W, 550 W, and 600 W.

Nippon Sheet Glass (NSG), Japan’s largest glassmaker, plans to show photovoltaic windows developed by its US unit, Ubiquitous Energy, at a train station in Japan. The windows feature a transparent photovoltaic coating with an invisible element of power generation, capable of absorbing non-visible wavelengths.

pv magazine speaks to Tim Riedel, who owns a 24 kW residential rooftop PV system and a 12.86 kW air-source heat pump, about the return on investment for air-source heat pumps and the savings households can achieve by pairing them with PV.
