Low-cost 'solar absorber' promising for future power plants

Emil Venere for Phys.org: Researchers have shown how to modify commercially available silicon wafers into a structure that efficiently absorbs solar energy and withstands the high temperatures needed for "concentrated solar power" plants that might run up to 24 hours a day.

PVinsights: China Demand Recovery Decelerates Solar Slump

Alternative Energy - Thu, 04/06/2017 - 08:49
Global solar panel prices continue to drop this week, extending the longest losses since 2017, but the rate of decline has slowed significantly from previous weeks. The demand in China has restored momentum in April. However, the demand recovery would still not be strong enough to reverse the downtrend of prices, but should help to limit the scope of decline. Meanwhile, although the demand in China has improved, the demand in rest of the major solar markets still appears to be lackluster. In EU and the US, solar panel prices were slashed sharply since 4Q16 and recently major module makers have ceased aggressive pricing. In Japan and India, fierce competition in these regions in efforts to win PV projects in 2H17 continue to drive solar panel prices lower.

48V Mild Hybrid: Greater Ambitions Now

Alternative Energy - Wed, 04/05/2017 - 12:04
At the excellent Electric & Hybrid Vehicle Conference here in Sindlefingen, Germany, 48V mild hybrids are rightly a strong focus. The consensus is that we are quickly moving beyond the opening shots that can reduce carbon dioxide by up to 14%. These tend to involve belt starter generator BSG, no electric drive modes, PO/1 positioning on engine, 480Wh 48V battery and 12 kV supplied. This was described as little more than an upgraded stop-start albeit with cold start, fast start, quietness and fuel economy.
