Potential-induced degradation (PID) is still one of the main reasons for unpredictable power losses in PV power plants. Volker Naumann, Otwin Breitenstein, Klemens Ilse, Matthias Pander, Kai Sporleder and Christian Hagendorf of Fraunhofer CSP examine how the PID susceptibility of PV modules is influenced by environmental stress. It is found that PID may develop in originally PID-resistant modules after a period of one to three years of unsuspicious operation, depending on climatic conditions
Some intriguing, colourful and exciting images of new tech, new solutions and one or two 'only in Japan' ideas from Day One of World Smart Energy Week, incorporating PV Expo, International Smart Grid Expo, Battery Japan Expo and more.
The new Q1 2020 bankability analysis has now been completed by the PV-Tech market research team, ranking PV module suppliers within the PV ModuleTech Bankability Ratings. The listing reveals that LONGi Solar now commands AAA-Rated status, the highest grade achievable. A further seven module suppliers are in the AA and A bands and four suppliers fall into the B levels.
Carrie Xiao speaks exclusively to Trina Solar vice general manager and executive vice president Yin Rongfang on the company’s continued R&D, the roadmap for its new 210 module and why he feels modules remain “grossly undervalued” in the solar supply chain.
It has always been anticipated that by the early 2020s, the feed-in tariff would have tapered away in Japan’s booming solar market. Andy Colthorpe speaks with analyst Izumi Kaizuka at RTS Corporation to learn more about what the future holds for post-subsidy solar in Japan.
Growatt has introduced its new XH series of storage ready inverters that works with a low voltage battery and has a battery interface which can be easily extended later to a storage system without retrofit cost, providing home owners who are looking to convert their rooftop PV systems into solar storage systems in the future.
PV Tech’s Carrie Xiao gets the details behind TBEA Sunoasis’ new strategy targeting hybrid-powered microgrids, and how its product suite is driving that market.
With the spin-off of most of its solar cell and PV module manufacturing operations to new entity Maxeon Solar Technologies (MXT) expected in Q2 2019, SunPower shed new light on the planned capacity expansions of the new offspring in its fourth quarter earnings call.
In a guest blog for PV Tech, Austin Ditz, senior project manager for project operations; and Eugene Rhee, director of performance engineering, both of Sol Systems, run through five of the most common technical problems with solar deployment that can be avoided through integrated delivery and engineering processes.
PV Tech talks exclusively to LONGi founder and president Li Zhenguo, discussing the module manufacturer’s rise, its aggressive expansion and the trends driving it forward
