Saft and Nedap have decided to join forces to create effective energy storage systems, based on state-of-the-art lithium-ion (Li-ion) battery technology, that will enable on-grid photovoltaic (PV) installations to make the optimum use of the solar power they produce. Saft Li-ion battery modules, designed specifically for energy storage in residential and commercial PV applications, in combination with Nedap’s PowerRouter solar inverter with...

Enova Systems has delivered 4 incremental 120kW drive systems to Optare Plc for integration into their Solo Electric Bus.

Heliatek GmbH continues to set new world records for organic solar cells. The company has commissioned SGS, an accredited and independent testing facility, with a measurement campaign of its latest organic photovoltaic (OPV) cells. The result of this campaign is a new world record for OPV with 10.7 % cell efficiency on 1.1 cm2. It also confirms the superior low light and high temperature performances of OPV compared to traditional solar technolog...

Konica Minolta Sensing Americas, Inc. launched its AK-120/130/140 Photovoltaic (PV) Reference Cells, the world’s first triple junction solar reference cells. Now available, the AK-120/130/140 is the latest addition to the AK Series of reference cells. KMSA first introduced its AK Series in 2010 at the SPIE Optics and Photonics conference to much industry excitement. Reference cells are used as a standard point of calibration to ensure consiste...

The following application note describes the modifications implemented on the STEVALISF001V1 demonstration board, originally designed to work as a PFC rated for a power of 3 kW, to be used as a front-end boost stage for photovoltaic applications. In recent years the field of solar energy, the production of electric power using solar cells, is requiring power electronic solutions to manage the power delivered by the panels.

Following a short overview of types of solar power systems and converters, this application note introduces a fully working, grid-connected solar inverter prototype suitable for rooftop applications. This solar inverter has been equipped with STMicroelectronics’ MDmesh and silicon carbide (SiC) devices to allow evaluation of these products in “green” technologies.

Goldwind has announced the launch of its GW93/1500 ultra-low wind speed permanent magnet direct-drive (“PMDD”) turbine. The Group’s latest R&D achievement leverages its well-established 1.5MW PMDD turbine platform as the foundation for a new series with power generation efficiency that is among the highest in the industry.
