A group of scientists led by the R&D center of Dubai Electricity and Water Authority (DEWA) has developed a new methodology to conduct on-site I-V curve measurements in PV systems. “It is common ...

Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs. The ...

In my previous article on photovoltaic (PV) systems (“The Highs and Lows of Photovoltaic System Calculations” in the July 2012 issue), I went through methods to calculate the changes in voltage due to ...

As envisioned by First Solar at their Analyst Day in 2016, the MVDC plant architecture replaces DC combiner boxes with DC-DC converters that boost string voltages from 1500V DC to the range of 5kV DC ...
