The solar rebound effect in residential PV
The rebound effect consists of a reduction in expected gains from a more resource-efficient technology as a result of behavioral or systemic change. An international research team has investigated this phenomenon in the residential PV segment in Vietnam and has found that it could happen in any country where the policy supporting solar power is not fully and scientifically explained.
Hybridizing PVT energy with heat pumps, borehole storage
A European research group has tested an energy system combining PVT collectors, a water-to-water heat pump and borehole thermal energy storage in an Italian swine farm and has found the proposed system can completely replace fossil fuel-based power generation.
Deye releases new 50 kW/61.4 kWh battery
Chinese inverter manufacturer Deye has developed a new all-in-one energy storage system (ESS) with 50 kW of output and 61.4 kWh of storage capacity. It features LiFePO4 batteries with a maximum temperature of less than 40 C.
New CIGS solar cell design with antimony trisulfide promises 31.15% efficiency
The novel solar cell uses antimony trisulfide (Sb2S3) as the back surface field (BSF) layer. According to its creators, this layer can be included in conventional CIGS solar cells to improve their efficiency and reduce the absorber material’s cost.
TSUN releases new series of microinverters
Chinese manufacturer TSUN says its Titan series of microinverters can handle 15 A of continuous input DC current. They also feature a 97.2% efficiency and four maximum power point tracking (MPPT) channels.
Robotic measurement system assesses new materials for solar cells
Researchers in Japan have developed an automated system to perform photoabsorption and photoluminescence spectroscopy, optical microscopy, and white-light flash time-resolved microwave conductivity tests.
New anti-reflective coating for silicon solar cells
Developed by an international research group, the novel anti-reflective coating is based on silicon dioxide and zirconium dioxide. It reportedly minimizes a solar cell’s reflection loss, while enhancing its light absorption properties.
SolaX Power releases new residential batteries
China’s SolaX Power has developed two lines of integrated energy storage systems that reportedly support up to 200% PV oversizing. Their rated output power ranges from 3 kW to 15 kW.
Photovoltaics for wastewater disinfection
Researchers in Spain have developed a new system that simultaneously produces PV power and disinfects wastewater.
Behavioral perspectives on adoption of residential PV systems
Scientists in China have used computer simulations to gain a better understanding of the factors that influence the adoption of residential PV.
