An MIT-spawned company has teamed up with architects and an Italian frozen-desserts brand to design an origami-inspired umbrella to power fridges.

Although self-consumption of solar power is the optimal economic approach, the expense of household batteries at present outweighs the increased ability they offer to use electricity generated on the roof. Whether aggregated ‘virtual batteries’ offer better returns is an open question, due to lack of electricity company transparency.

The research group led by Professor Martin Green has published Version 58 of the Solar cell efficiency tables. He spoke with pv magazine about the criteria with which these tables are compiled and the importance of result certification by independent third parties.

DuPont has developed a repair kit for PV modules with backsheet failures. Cracked and chalking backsheets can cause problems for solar project owners, but this could easily be addressed in the field without swapping out the PV modules. Stéphan Padlewski, regional marketing leader EMEA at DuPont Photovoltaic Solutions, spoke to pv magazine about how the solution works.

PV module making is a brutally competitive industry. And for Slovenian module maker Bisol, in business since 2004, one of the keys to success has been to remain focused on the value its products deliver to the customer. And as company founder and CEO Uroš Merc explains, in 2021 this means reimagining module degradation.

Despite the growth, one-off exceptional events in the fourth quarter hit the solar EPC’s overall fiscal performance. These included a prime subcontractor going bankrupt in Australia, rising module prices, and increased freight costs.

Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists. The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen.

Conventional incentives such as renewable portfolio standards, feed-in tariffs or feed-in premium payments may lead to a price cannibalisation scenario for wind and solar, according to a new study from a German-Swedish research group. CO2 pricing is, however, considered an efficient tool to maintain their market value high enough to ensure new investments. A total system cost approach, rather than an LCOE perspective, is needed to understand the strong dependence of market value on policy choice though.

This year, PV cell manufacturers will face the challenge of transformation. Apart from adjusting the ratio of production for different-sized cells, some manufacturers are turning to next-generation opportunities, shifting investment from p-PERC to n-type technology. PV InfoLink Analyst Amy Fang discusses the issues facing n-type cell development this year.

Despite the impact of the pandemic and associated economic crisis, 2020 saw unprecedented growth in the solar market. With the International Energy Agency stating that high rates of capacity additions are the new normal, has the energy and investment environment fundamentally changed? Felicia Jackson in London explores these issues.
