The weekend read: Inverter issues

PVEL’s inaugural inverter scorecard is showing up the need for much more scrutiny on the reliability of inverters. But are developers and EPCs even paying attention?

IRENA and the UN ink agreement to combat desertification with renewables

A memorandum of understanding signed by the institutions was not solar specific but the use of PV modules for shading, especially in agriculture, can reduce water consumption and help halt the expansion of deserts.

Solar-plus-storage vs grid enhancement part II

Grid expert Andrea Mansoldo tells pv magazine how energy markets based on solar and storage are feasible as an alternative to costly grid infrastructure work. He says around 6 GWh of battery capacity may be a good alternative to building 1000km of power line or an AC 750 kV high-voltage line.

The cooling effect of PV

Research from Finland’s Aalto University claims the residential cooling sector could sustain 540 GW of solar generation capacity if the world’s air conditioning systems were solar powered. Academics say synergies between PV and the cooling industry will become stronger as demand for the latter shifts nearer the equator, where seasonal differences in weather are less pronounced.

The energy transition is easily affordable but all hope of 1.5C warming will vanish in 2028

Technical consultancy DNV GL has published its Energy Transition Outlook 2019. While the electric vehicle, storage and renewable energy industries are likely to see significant rises in demand, the sobering conclusion is the world will miss carbon reduction targets by a long shot.

New methods for fault detection revealed at EU PVSEC

Quality control and problem detection and classification was brought into focus at the conference in Marseille. A packed house at a session focused on the latest fault detection techniques indicated the high level of interest in the field.

Recovering interest rates may raise large scale solar electric price 11%

Renewables investment may by hit by rising interest rates despite the falling cost of clean energy tech just as fossil fuels avoid the impact of rising base rates.

Solar pioneer Pierre Verlinden: The big problem is apathy

On the first day of this year’s EU PVSEC conference, veteran solar researcher Pierre J Verlinden won the Becquerel Prize for Outstanding Merits in Photovoltaics. The award recognized more than 40 years as a leading PV researcher in academia and at leading companies including Sunpower and Trina Solar. Its recipient spoke to pv magazine about what is needed from solar to stave off catastrophic climate change.

Maximize the benefits of solar energy through techno-ecological synergies

The dire assessment from the International Panel on Climate Change (IPCC) made it very clear this past year: To avoid the worst impacts of the climate crisis, a significant shift to clean energy sources must be well underway by 2030.

Eric Luo: China will see just 20-25 GW of solar per year through 2025

The GCL System chief executive made comments that fly in the face of an expected solar gold rush in China that analysts predict will start this month. Though rising overseas demand will address overcapacity fears, according to Luo, the soundbite is sure to chill PV boardrooms across the world’s biggest solar market.
