New microinverter from the US
Yotta Energy’s new micro-inverter is claimed to be an ideal solution for commercial rooftop PV systems linked to between 500 kWh and 1 MWh of storage. The device has a peak efficiency of 96.5% and a nominal maximum power point tracking (MPPT) efficiency of 99.5%.
Solar energy collectors… grown from seeds!
Rice University engineers produced “near-perfect” 2D perovskite crystals for photovoltaic applications, grown from seeds.
Concrete flywheel storage system for residential PV
A French start-up has developed a concrete flywheel to store solar energy in an innovative way. Currently being tested in France, the storage solution will be initially offered in France’s overseas territories and Africa.
Black perovskite solar cell with 15% efficiency via thermal evaporation
The cell exhibited an open-circuit voltage of 1.1 V and was able to retain around 90% of its initial performance after 215 days of exposure to dim light at room temperature. According to its creators, this performance and the notable stability were ensured by the thermal evaporation technique used for depositing the perovskite layers onto the cell.
Solar 101: It all comes down to curb appeal
The residential solar industry has taken notice of the demand for beautiful, hidden panels, and is now providing creative and attractive designs that you can incorporate into your rooftop solar project.
Flexible perovskite solar module with 10.5% efficiency
The methylammonium-free inverted solar module was built on a flexible substrate made of polyethylene terephthalate (PET). A hole transporting material made of poly(triarylamine) (PTAA) and a double-cation cesium formamidinium (CsFA) perovskite layer were deposited through blade-coating and nitrogen-assisted blade-coating.
Stand-alone brackish water desalination system powered by photovoltaic-thermal unit
The BWRO unit, which has a treated water production capacity of around 11.80 L/h, was built with a pre-filtration module, a high-pressure DC pump, an RO module, and a post-treatment module. The PVT system was designed to meet the energy requirement of a high-pressure DC pump and a diaphragm-type circulation pump utilized to circulate soft water beneath the PV module for the active cooling of the panel itself.
Roll-out solar arrays installed in successful NASA spacewalk
The first new ISS Roll-Out Solar Array (iROSA) has been installed on the International Space Station.
Saule Technologies opens perovskite solar cell factory in Poland
The Polish perovskite solar cell specialist claims to be the first company in the world to have commissioned commercial production of the technology.
