IRENA says global solar capacity rose by 345.5 GW in 2023

The International Renewable Energy Agency (IRENA) says developers installed 345.5 GW of solar throughout the world in 2023. China mainly drove the surge, accounting for nearly three-quarters of all new renewable energy, but IRENA says more equitable growth will be needed to hit 2030 deployment targets.

Hydrogen batteries vs. lithium-ion batteries

Researchers in Australia have compared the technical and financial performances of a hydrogen battery storage system and a lithium-ion battery when coupled with rooftop PV. They evaluated two commercially available systems – LAVO and Tesla Powerwall 2 – and found that the lithium-ion battery provides better financial profits, whereas the hydrogen battery offers more battery lifespan for long duration of energy storage.

Israel hits 51% renewable production for first time

The Israeli government said that earlier this month, for several minutes, renewable energy accounted for most of the nation’s energy production. In particular, solar covered 45% of total generation.

Inverter undersizing not universally effective to reduce soiling losses

An international research team explained that, although inverter clipping is initially effective in mitigating soiling losses, these losses could become more visible with time, as solar module degradation makes clipping less frequent. They also warned that inverter undersizing alone may not be enough to mitigate soiling losses and suggested cleaning as an additional way to reduce them.

RCRS Innovations to scale lithium battery manufacturing capacity, launch new product lines

Noida-based RCRS Innovations Ltd, the parent company of lithium-ion battery manufacturer EXEGI, plans giga-scale expansion. It will also launch container-sized energy storage solutions with megawatt-hour level capacities and add TOPCon products to its range of solar panels.

Tesla’s new power play

The first installations featuring the Tesla Powerwall 3 are currently being completed in the United States, with the company promoting a fully integrated solar-plus-storage and electric vehicle (EV) residential system, with big backup power capacity. While the first Powerwall created a new market segment, the latest iteration enters a marketplace in oversupply.
