International researchers have analyzed the potential of sodium-based energy storage and found recent technical advances have arrived faster than those for the lithium-ion batteries which have been studied for three decades. Issues remain, however, before sodium constitutes a complementary option to lithium.
U.S.-Spanish researchers have proposed a new way to assess the reliability of PV modules and their warranties. It is impossible to fulfill a 25-year warranty if the threshold of returned modules exceeds 5% and the annual degradation rate is over 0.73%.
Three big projects are candidates for support from the Covid recovery plan laid out by the bloc.
Module manufacturer Trina Solar has completed the acquisition of the Spanish tracker company, inverter maker Sungrow has secured contracts from Three Gorges New Energy and Akcome Technologies has completed construction of its heterojunction cell and module factory.
Solar is regaining speed in Spain after the Covid-19 crisis. Iberdrola is now building 150 MW, while Foresight recently acquired a 26.1 MW project. FRV has secured financing for a 136 MW array, Audax plans to issue green bonds to finance its pipeline, and an 800 MW solar park is expected to provide with power Alcoa’s aluminum plant in Galicia.
