China is importing less and less silicon. Western manufacturers are selling to Vietnam!
Silicon imports by China have fallen to their lowest level since 2011. Non-Chinese silicon producers have been shipping larger volumes to South East Asia, says Bernreuter Research. This shift in destination

Which agrivoltaic system should I use for my olive groves?
What type of agrivoltaic installation is best for olive groves?
"The vertical inclination of the photovoltaic panels was found to be optimal for maximising the yield of olive trees", said the author of the study. "This unexpected finding highlights the nuanced interaction between the orientation of photovoltaic panels and the agricultural productivity of olive trees in agrivoltaic systems."

A new floating photovoltaic system has been developed
A new floating photovoltaic system has been developed by Spanish researchers.
"The novelty of the system lies in the combination of a dual-axis solar tracker with a mini-tensioning platform (TLP). "This is the first time that these two concepts have been proposed for a floating solar system, and HelioSea integrates the two.

Hydrogen production by electrolysis of water is still too marginal
The production of hydrogen by electrolysis of water is still not sufficiently achieved using solar energy. Projects are still too few and too far between to measure the performance of solar energy as a source of power for electrolysers. We have to wait until they are up and running and producing. One of the reasons for this is the intermittent and uncontrollable nature of solar energy.

The rebound effect of solar energy.
Researchers from Australia and Vietnam have analysed the short- and long-term dynamics of the rebound effect of solar energy.
The rebound effect is a reduction in the expected gains from a more resource-efficient technology resulting from a behavioural or systemic change.

How can a floating solar power plant be improved over a land-based plant?
What characteristics does a floating solar power plant need to have in order to optimise its production compared with a ground-based plant?
Researchers in Malaysia and India have analysed the effect of height, angle of inclination, wind speed, ambient temperature and water temperature on the efficiency and output of floating solar PV (FPV) compared with a conventional ground-mounted solar system.
