Response to the application for import tariffs on solar panels

BusinessChief.com reports that SegenSolar, a southern African subsidiary of the UK’s Segen group, has offered an opinion on South Africa’s proposed introduction of tariffs on all imported crystaline silicon photovoltaic (PV) solar panels. On 29 March 2019, the International Trade Administration Commission of South Africa published an application proposing the introduction of tariffs on all […]

Death of internal combustion: 1000 km EV range  

Electric aircraft have arrived. Cars are next. With no road resistance, the best electric aircraft, the Bye Aerospace eFlyer, achieves 1000 km with its solar wing option. This range will be the final nail in the coffin of internal combustion cars.    1000 km range for an electric car calls for four essentials: Extremely low drag […]

Locally made inverters for new solar farms

RWW Engineering, a South African manufacturer of electrical equipment for industry and utilities, has been appointed the South African manufacturer of inverters for Spanish company Green Power Technologies. The inverters will be used at three 75 MW solar PV farms which are being built as part of Round 4 of South Africa’s Renewable Energy Independent […]

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, […]
