Researchers develop new material for efficient and sustainable organic solar cells

  A team of researchers from Friedrich Alexander University (FAU), Nuremberg, led by photovoltaics researcher and materials scientist Prof. Dr. Christoph Brabec have achieved an important milestone in the quest to develop efficient solar technology as an alternative to fossil fuels. Together with colleagues from Imperial College London and the King Abdullah University of Science […]

Smart buildings – protagonists of the smart grid

  The smart grid is the future of our power supply. Smart grids need smart buildings. Equipped with modern building automation, these buildings can be used as a counterbalance in the complex interplay between power generation and energy demand. The growing importance of user-generated energy and the different ways in which energy can be stored […]

Preventing system failure in solar PV systems

  It is vital for solar photovoltaic (PV) systems to accommodate the temperature fluctuations and environmental conditions to which they are typically exposed as these conditions often cause ongoing system failure. The difference between standard test conditions (STCs) and nominal operating cell temperature (NOCT) is of interest here as these values in PV modules determine […]

Lightning and surge protection for rooftop PV systems

  Apart from damaging solar photovoltaic (PV) modules, inverters and monitoring elecronics, lightning strikes also lead to field-based and conducted electrical interference. According to the South African Photovoltaic Industry Association (SAPVIA), photovoltaic (PV) is the fastest growing power generation technology in the world. More than 35 GW of PV is installed and operating worldwide, producing […]

Understanding the benefits of solar power

  Using solar energy would be a logical route for us to follow in an effort to alleviate the energy shortage. But we don’t. There are several good reasons why South Africans are reticent, amongst them being the cost of installation, lack of a clear understanding about what is available and, the fact that feeding […]

New PV projects bring 33 MW of extra power

Construction has already started on two of Africa’s most powerful photovoltaic (PV) plants as part of South Africa’s REIPPP.  These projects will be fitted with 6000 safeTrack Vertec azimuth tracking systems supplied by IdeemaTec Deutschland. Each of the trackers is equipped with 23 modules. The 22 MW Herbert project will use 4000 trackers, while the […]
