Debunking myths about PV system orientation, dimensioning
New research from Lappeenranta University of Technology shows that there is no single correct orientation for a PV installation.
UN chief warns more fossil fuel investment is ‘delusional’
As Australia battles an energy crisis, the United Nations secretary general has called for increased investment in renewables, saying it is the only “true path to energy security”, warning new funding from governments for fossil fuel exploration or production is simply “delusional”.
Lithium-ion vs. vanadium redox flow storage
UK scientists have compared the performance of lithium-ion storage systems and vanadium redox flow batteries for a modeled 636 kW commercial PV system in southern California. They have found that both technologies, coupled with an oversized PV array, could achieve a levelised cost of electricity of less than US$0.22/kWh (AU$0.32/kWh), while offering a self-sufficiency ratio of 0.95.
Megasol reveals new solar PV in-roof system
Swiss module manufacturer Megasol has unveiled a novel rooftop PV system in two variants — full-black and translucent. The installation consists of vertical supports, a ridge profile, and solar modules.
Silver-alloyed CIGS solar cell with transparent indium back contacts, 12% efficiency
Scientists in Sweden have developed a wide-gap ACIGS solar cell with hydrogen-doped indium oxide (IOH) transparent back contacts and silver alloying to increase the absorber bandgap energy. The device achieved an efficiency of 12.0%, an open-circuit voltage of 835 mV, a short-circuit current of 22.1 mA cm2, and a fill factor of 65.2%.
New solar module for pavement applications
Hungarian tech company Platio Solar has developed a new solar PV paving line featuring monocrystalline and polycrystalline cells with clear or opal glass.
Downsizing gallium nitride inverters
A German consortium led by Fraunhofer IEE aims to bring gallium nitride inverters closer to commercial viability. The primary goal of the research project is the optimisation and miniaturisation of inverters, including passive components such as cooling systems, casings, and mounting structures.
Green hydrogen price may drop to $7.5/kg by 2025
Aurora Energy Research says in a new report that maximum green hydrogen project profitability could be achieved when solar and wind power plants are combined with electrolysers.
BYD launches new C&I battery
Chinese battery manufacturer BYD has launched an expanded portfolio of energy storage systems designed for the commercial and industrial solar markets. At The smarter E in Munich last month the company also provided a sneak peak at a new high-voltage storage system expected to be launched later this year.
Melbourne-based 8 Star Energy set to shine in Europe
Melbourne-based 8 Star Energy has been announced as a distribution partner alongside Germany-based Memodo as world leading battery brand Energizer launches its Energizer Solar PV portfolio across Europe.
