Test of near-vertical installation of panels at altitude
Swiss company Axpo is installing 2 MW of solar power on the walls of the water reservoir in Muttsee (canton of Glarus, Switzerland) at an altitude of 2,500 metres. The panels in the upper row have an inclination of 77°, while the lower row would be set at 51 degrees of inclination.
Several studies show that PV systems in mountainous regions can produce a lot of electricity, even in winter. Axpo estimates that during the winter months, the system will supply around half of its annual electricity production, compared with around a quarter of the annual production of similarly sized plants in the relatively flat lowlands of Switzerland. The absence of fog is one of the many advantages of high-altitude projects, as clear skies mean more solar radiation. The panels are also more efficient at low temperatures, in addition to the advantages of the bifacial effect of snow.
If this project lives up to expectations, it will help mitigate the seasonal decline in electricity generation in winter due to fog, clouds and lower levels of solar radiation.
Swissolar, the photovoltaic association, estimates that a total of 50 GW of photovoltaic capacity will be installed to meet Switzerland's future energy needs, replacing fossil fuels in the context of the gradual reduction in nuclear capacity. This amount of solar energy is 25 times more than the country has already installed to date.
PV Magazine of 28 November
Editor's note This experiment only goes in the direction of a search for the best ways to produce energy with the panels. All the tests are carried out. We had the panels laid vertically, installed them five metres above the ground to improve agricultural production, placed them on lakes, soon on the sea, placed the panels to obtain the reflection of the luminosity on the ground (by the albedo)... We are looking in all directions.

Analysing hybrid power plants in another way
The American NREL has been studying the potential of hybrid power plants that combine wind, solar and storage. The development of such plants is driven by the need to increase profitability and to take into account parameters beyond the discounted cost of electricity, taking into account time-varying revenues and better managing the variability inherent in renewable energy.

La réalité de l'hydrogène vert derrière le battage médiatique.
L’hydrogène est de plus en plus considéré comme un atout essentiel pour la décarbonisation des réseaux et des transports. L'intérêt pour cette technologie est en hausse : Shell estime que le secteur de l'hydrogène mérite les mêmes niveaux de soutien que ceux accordés à l'énergie dans le passé.

Les ventes de panneaux bifaciaux se font surtout dans les pays émergents
En juin 2019, les Etats-Unis libéraient les importations de panneaux bifaciaux de droits de douane, puis supprimaient cette suppression le 28 octobre. Un tribunal a suspendu l'exécution de cette suppression le 21 novembre. Les ventes n’ont pas eu le temps de s’instaurer. Les importateurs se méfient des décisions trop brutales.
Cette modification non encore définitive modifie les perspectives du marché des panneaux bifaciaux. Ils sont concentrés dans les pays émergents, selon les douanes chinoises

On se préoccupe de recycler les batteries usagées
Certains s'inquiètent déjà de l'abondance de batteries lithium-ion en fin de vie, provenant de véhicules électriques. Ils affirment que chaque million de véhicules électriques en fin de vie produira 250.000 tonnes de batteries. Parmi ceci, il y a de nombreux métaux rares et coûteux.
