Huge Vietnamese solar park could hit 2.8 GW within a year
An energy transition investment report published this week has also revealed the former world record low price for solar power announced by the Al Dhafra project in Abu Dhabi last year, has fallen even lower since.
German start-up offers 5.2 kWh AC battery that works without inverter
Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.
New residential lithium-ion battery from Germany
The battery system, which is aimed at increased self-consumption, can handle a maximum DC input power of 18 kW and 1000 V.
Micro-inverter for balcony solar modules
Two different devices designed by German manufacturer Bosswerk can feed up to 300 or 600 watts into the home network. The company offers a 12-year guarantee.
Sonnen battery still running after 28,000 full charge cycles
Sonnen has published test results indicating the longevity of its storage systems after extended use.
Germany’s first tender for rooftop PV concludes with average price of €0.0688/kWh

The Hydrogen Stream: Plans for $75bn, 50 GW green energy hub in Western Australia
Plus, as the European Commission prepares to present its ‘Fit for 55’ climate change package tomorrow, European companies are continuing to develop hydrogen plans, including Shell in Norway and Siemens in Germany.
Bringing the noise for better solar cell efficiency
An international team of scientists developed a technique to isolate individual sources of electrical ‘noise’ within a solar cell. Comparing the technique to being able to pick out a single voice within a 200-person choir, they say the technique will help to improve understanding of where efficiency losses occur within a cell, and effective ways to mitigate them.
SMA, Renusol link planning tools
The German companies plan to combine their tools for project planning and battery systems via a new interface. They aim to simplify the work processes of planners and installers.
Solar+storage could provide 80% of annual EV power needs
A new EUPD Research report shows that a PV system can cover 39% of the power demand of an electric vehicle, but this potentially rises to 80% if storage is included.
