Choice of PV backsheet material affects module life

DuPont Photovoltaic and Advanced Materials’ (DuPont’s) 2019 Global Field Reliability Study shows that the choice of backsheet material used on PV modules can result in significant degradation and negatively impact solar module performance. The report lays out failures with PET, polyamide and PVDF backsheets and issues with glass-on-glass modules. The report also highlights trends in […]

Africa’s energy landscape transitions to base load-capable renewables

The advent of renewables, new storage technologies present Africa’s utilities with an opportunity to increase capacity and efficiency while re-kindling their appeal to investors.  There has been a clear and rapid evolution in Africa’s energy and energy infrastructure landscape over the last decade. While much of this new technology has challenged the traditional dominance and […]

Leading in renewable energy finance

Even a brief search of the headlines of newspapers around the world will leave one in no doubt that the threat posed by climate change has morphed from being solely a focus of climate activists to one of global concern. The climate emergency is now being recognised at board level, so contributing towards meeting the […]

Pairing solar and storage challenges gas peakers

Gas peakers have been around even before the recent rise of renewables made them even more indispensible. How else could grid operators fill in the void created by the vanishing solar generation when the sun sets at the end of the day or when wind stops spinning the wind turbines’ blades? And with natural gas […]

Safe, robust, repeatable and reliable solar energy 

Using innovative technology, the latest fixed-string voltage innovation in photovoltaic (PV) solar systems introduces a significant advantage over commonly deployed traditional string inverters.  Before we look at the advantages offered, allow me to explain what is meant by a “fixed-string voltage”. By using a maximum power point tracking (MPPT) electronic device at each PV module, […]

Nuclear power in a clean energy system

Nuclear power today makes a significant contribution to electricity generation, providing 10% of global electricity supply in 2018. In advanced economies, nuclear power accounts for 18% of generation and is the largest low-carbon source of electricity. However, its share of global electricity supply has been declining in recent years. The International Energy Agency’s (IEA’s) report, […]

Lightning protection provided for large poultry farm’s solar installation

Lightning and surge protection specialist Dehn Africa was recently involved in an extensive project to provide and protect rooftop solar power to one of South Africa’s largest poultry farms, Chubby Chick, in Potchefstroom. All parties involved worked closely together from design to commissioning, ensuring the installation was comprehensively protected from lightning effects during its lifetime. […]

Large-scale South African solar water-heating projects save money and the environment

Industry uses more energy in the form of heat than as electricity, giving South African companies the perfect opportunity to exploit the country’s abundant solar and wind resources to produce power and heat for the re-industrialisation of the country. Speaking at the launch of two of Southern African Solar Thermal Training and Demonstration Initiative’s (Soltrain’s) […]
