Saturday read: Battery performance, uncovered

Batteries are taking the energy world by storm. From residential home storage systems to large-scale installations, today’s society increasingly relies on powerful batteries. And, as we all know, with great power comes great responsibility. But, how can we ensure that our use of batteries today is responsible, cost-effective, or even safe? Kai-Philipp Kairies, CEO of Accure Battery Intelligence, shares some of his experience gained from monitoring more than 750 MWh of various storage applications.

Sunday read: A decisive movement in module prices

The sky is the limit. Fortunately, this expression does not apply to current prices for PV panels, which have recently declined, following a continuous rise since the beginning of the year. Whether this situation holds, or whether prices drop further in the coming months is hard to say at the moment, writes Martin Schachinger of pvXchange. Polysilicon prices and thus wafer and cell prices could be in for a slight decline. However, a decisive movement in module prices in general is unlikely before the fourth quarter.
