BloombergNEF and Sustainable Energy for All have jointly published a report by the Mini-Grid Partnership proposing solar minigrids as a critical technology to bring electricity to the 789 million people who still lack access.

The module manufacturer and micro-inverter supplier will connect their products in the factory to reduce installation costs, while providing a list of value propositions for micro-inverters.

pv magazine’s Quality Roundtable this year brought together experts from a broad range of applications relevant in the solar industry. The overarching theme this year was quality concerns with new technologies. Experts from companies and research institutes held that the failures that the industry has observed with technologies such as 2P single-axis trackers are not inherent in the technology but can be addressed.

The storage technology promises ten times the energy density offered by lithium-ion batteries but notorious cycling instability remains a concern. Researchers in South Korea may have come a step nearer a solution.

Hydrogen-fueled aviation has a realistic chance of helping the sector achieve climate goals, according to a European Union-commissioned study.

They are words to chill the soul of solar project owners when uttered in relation to feed-in tariffs: retroactive FIT cuts. A Ukrainian government smarting at the cost of funding an overly successful solar incentive program appears bent on emulating the approach of governments in Spain, Italy and Czechia by reopening signed payment contracts to reset the monies paid for clean power, despite the costly lawsuits that have greeted such moves in the past.

The European Commission has sent the European Green Deal on its way and a preliminary version of its anticipated hydrogen strategy has been leaked. The plan does not lack ambition, as the EU seeks to assert tech leadership in green hydrogen through coordinated efforts across the value chain.

The EU appears poised to roll out battery storage capacity to provide flexibility to systems with more variable renewables. The European Commission’s Directorate-General for Energy has also noted policies that must be addressed to establish a level playing field for storage.

Chinese manufacturer JA Solar has announced a new 525 W+ panel and said the product will be available from the second half. Domestic rival Risen has shipped the first batch of its high-powered modules and intends to stick to pre-Covid-19 plans to ramp up production.

The International Seabed Authority will change regulations for deep-sea mining this year. The ocean floor is covered with potato-sized pebbles containing high levels of cobalt, manganese, nickel and copper – materials that could soon be in short supply as the energy transition progresses.
