In arid regions soiling can greatly impact the energy yield of PV systems and drive up their O&M costs. Benjamin Figgis, Amir Abdallah, Maulid Kivambe, Brahim Aissa, Kamran Ali, Cédric Broussillou and Veronica Bermudez of the Qatar Environment & Energy Research Institute and Klemens Ilse of the Fraunhofer Center for Silicon Photovoltaics review the main challenges associated with soiling of PV plants globally, and the most promising techniques for dust prevention and cleaning in dry climates, drawing on research results from six years of PV performance and soiling studies at the QEERI’s Outdoor Test Facility in Doha
Nuclear reactors approaching end-of-life, a sound PV manufacturing industry and a robust legal system all make a strong case for solar PV to muscle into Taiwan’s energy mix. Last year, a new government set a target of 20GW solar by 2025, but the industry must deal with scarce land availability and the threat of typhoons. PV Tech examines some of the huge numbers being proposed and what it will take to realise them.
With competition in the tracker marketplace becoming extremely fierce, rival companies are adding new features all the time aimed at minimising installation and operation costs, and enhancing durability. Here we profile some of the single-axis trackers currently available on the market and the innovative design features they offer.
Energy storage in the US is being propelled forward by falling costs and increasingly favourable markets and policy. But for the full value of storage to be realised, numerous regulatory and fiscal barriers must still be surmounted, writes Matt Roberts, executive director of the Energy Storage Association.
Over the past 12 months, the US solar business has been on a rollercoaster ride, with the high-profile bankruptcy of SunEdison and the merger of SolarCity and Tesla stealing the headlines. Danielle Ola talks to the experts about some of the key trends shaping the world of solar finance and investment in the US.
