In a four-year project sponsored by the German Federal Ministry of Economics and
Energy, a consortium of German experts assessed the quality of actual PV power installations.
The researchers now report on how the effects of several common module failures on module and
string performance highlight the importance of consistent quality assurance to prevent risks to
financial success

Welcome to the first 2018 edition of PV Tech Power. The focus of our cover story is an area that has been exciting the editorial team here at PV Tech Towers for some time. Floating solar presents an entirely new pillar of solar deployment, as discussed at length by the Solar Energy Research Institute of Singapore (SERIS). In our Market Watch section we have expert coverage from Apricum of the booming Chinese market, exploring how the country’s vast demand, the so-called ‘hungry dragon’, will be satisfied in 2018 and beyond. With PV Expo returning to Tokyo this quarter, Japan’s RTS consultancy provides an update on a market that, despite its challenges in recent years, continues to represent a multi-GW opportunity and so much more.
