Uniper to build Germany’s largest PV plant
Uniper plans to power a green hydrogen production facility in the German state of Lower Saxony with 317 MW of solar.
Italy’s solar installations hit 2.3 GW in H1
Italy deployed 2.3 GW of new solar capacity in the first half of the year, while its cumulative installed PV capacity reached 27.4 GW at the end of March, according to Italia Solare, the national solar energy association.
Mongolia completes 10 MW solar farm
Mongolia has connected a 10 MW solar farm to the grid, as part of a plan to deploy 40.5 MW of solar and wind capacity in the nation’s western regions.
ClearVue next-gen ‘solar window’ powers through mass production run
Australia’s ClearVue Technologies says it has confirmed the scalability and “commercial viability” of its second-generation integrated glazing units, following a mass production run using a standard manufacturing line at a factory in China.
Selenium solar cell built with laser-annealing achieves record fill factor of 63.7%
Built by Danish researchers, the device also achieved a power conversion efficiency of 5.0%. They designed the cell with a soda-lime glass substrate, a tin oxide (FTO) layer, an electron transport layer made of titanium oxide (TiO2), a selenium absorber, a molybdenum oxide (MoOx) layer, and a gold (Au) metal contact.
Integrated PVT–air source heat pump for deployment in limited space
South Korean scientists built an air source heat pump integrated with a photovoltaic thermal unit that can reportedly achieve an average heating and cooling coefficient of performance (COP) of 3.54 and 3.31, respectively. The system is also claimed to be 44% cheaper than ground source heat pumps combined with PVT energy.
Yaskawa Solectria Solar introduces 175-250 kW utility-scale string inverters
Yaskawa Solectria Solar has developed new utility-scale string inverters with capacities ranging from 175 kW to 250 kW. They are optimized for use with First Solar modules and qualify for the US domestic content bonus tax credit.
Solar for water deionization
Scientists in Canada have combined PV power generation with water purification based on capacitive deionization (CDI), which is claimed to have low operational cost, enhanced energy efficiency, and less water rejection than conventional purification techniques. The solar-powered system prototype is able to produce more water than a conventional CDI system on a sunny day.
Daikin presents mid-temperature refrigerant split heat pump
The new product can reportedly provide a leaving water temperature of up to 65 C. It is available in three versions with outputs of 8 kW, 10 kW, and 12 kW, respectively.
Kstar launches all-in-one lithium-titanate batteries for residential applications
The new batteries reportedly provide steady operation for up to 16,000 charge cycles. It has a storage capacity of 5.4 kWh and a depth of discharge of 90%.
