Photovoltaic-thermal module based on biochar-PCM achieves 79.6% efficiency
Indian scientists have developed a panel with an electrical efficiency of 13% and and thermal efficiency of 66.6 %. They built the system with a 100 W PV panel, a rectangular absorber, and a cooling technique based on a phase change material (PCM) that uses biochar derived from water hyacinth.
Hitachi Energy opens advanced power system factory in Chennai
The HVDC and power quality product factory will cater to the rising number of high-voltage transmission projects in India and export to support global HVDC installations.
Emmvee gets Fraunhofer ISE on board for solar cell line
India’s Emmvee Group has appointed Germany’s Fraunhofer Institute for Solar Energy as the technology partner for its upcoming 1.5 GW PV cell manufacturing facility.
New EV battery offers 50% more density than traditional lithium-ion batteries
Ionblox says it will use $32 million of series B funding to support the buildout of a novel silicon anode electric vehicle battery.
IIT-Madras Research Park signs thin-film R&D MoU with First Solar
IIT Madras Research Park and US-based First Solar will cooperate on a range of research and development (R&D) activities including the localization of thin film and other next-generation PV technology supply chains in India, high-volume manufacturing, PV module testing, and high-value recycling.
Survey shows 34.3% failure rate for residential inverters over 15 years
The Bern University of Applied Sciences in Switzerland has published the initial results of a survey on the durability and performance of residential PV inverters and power optimizers over a 15-year period. They found that more than 65% of the inverters did not present yield-relevant faults by their 15th year of operation.
Sodium aluminum battery for renewables storage
US researchers have designed a molten salt that could potentially reach an energy density of up to 100 Wh/kg at a cost of $7.02/ kWh. The battery uses an aluminum cathode that charges quickly and reportedly enables longer-duration discharge.
Dutch startup unveils controller to store excess PV power in hot water
Solyx Energy has developed a device to maximize solar self-consumption in residential homes. The sensor measures how much solar power can be fed back into the grid at different times, while a controller redirects that excess energy into an electric water heater.
Prime Minister flags off OIL’s hydrogen bus at India Energy Week
Oil India Ltd (OIL) indigenously developed this hydrogen fuel cell-based bus under its Startup incubation program SNEH. The bus is powered by a 60 kW PEM fuel cell.
AC vs. DC in residential buildings equipped with solar-plus-storage
Scientists in Sweden have compared AC and DC topologies in PV-powered buildings using battery storage. They have found that DC distribution systems can achieve energy savings when they are combined with solar-plus-storage systems.
