Weekend Read: Europe’s subsidy conundrum
On Nov. 6, the European Solar PV Industry Alliance (ESIA) published a recommendation paper in which it set out how its members envisage a European support scheme to foster the development of European solar. What chance does it have of actually achieving its goals? Götz Fischbeck delivers an assessment.
New multilevel PV inverter concept based on switched capacitors, single DC input
Scientists in India have developed a 500 W seven-level inverter prototype based on switched capacitors. The device is reportedly able to achieve a high efficiency despite switching, conduction, and capacitor voltage ripple losses.
