Distributed Storage

UK scientists have discovered that second-life batteries could provide a lower levelized cost of electricity (LCOE) than conventional batteries in school buildings equipped with PV in East African schools. They said the cheapest system configuration uses either 7.5 kW or 10 kW of solar with 20 kWh of storage.

Rapidly deploying 5.2 GW of planned solar and storage in Puerto Rico, a possibility raised in a report by six national laboratories, would require an improvement in the Puerto Rico utility’s practices. A mandated procurement process has suffered delays at many steps.

Researchers from Victoria’s Deakin University say they have successfully tested a new process that can safely and effectively extract silicon from end-of-life solar panels, and then convert it into nano materials worth more than $45,000 (USD 31,500) per kilogram, in order to build better batteries.

pv magazine Australia’s Natalie Filatoff reports on the benefits of planning vast solar project pipelines, and the barriers faced by those who dare to dream big.

Renac Power’s new hybrid inverters have efficiency ratings of up to 97.5% and European efficiency ratings of 97.2%. They are available in four versions, with power outputs ranging from 3 kW to 6 kW.

Esysunhome (ESYSH), a new energy storage company in China, has developed a 5.12 kWh lithium iron phosphate (LFP) battery system with a 7.9 kW inverter. It says six modules can be combined for up to 30.72 kWh of energy storage capacity.

Buoyant predictions about a rosy future for African photovoltaics, based on the continent’s abundant solar resources, continue to overlook the difficulties of securing investment, as Empower New Energy co-founder and CEO Terje Osmundsen explains, referring to a report published by the Africa Solar Industry Association at the World Future Energy Summit in Abu Dhabi today.

PV integration in smart grids is a complex but highly relevant issue, with various aspects to be considered to develop different scenarios. Researchers in the IEA-PVPS Task 14 program are conducting a survey to collect opinions from peers in the PV branch to perform such an analysis.

California-based Yoshino Technology has developed portable batteries using solid-state Li-NCM cell technology. The four variants come with power outputs of 330 W, 660 W, 2,000 W, and 4,000 W.

Once a European leader in PV deployment, the solar market in Czechia has slumbered for the last decade. Now, with growing public support and financing in place, momentum is building and a gigawatt-scale pipeline is taking shape. However, fresh challenges loom, as Marija Maisch reports.
