Greta Thunberg’s speeches and activism on Climate Change inspire me to no end. We need the sort of laser integrity and vigilance that this brave 16 year old girl has shared. That climate change and global warming is indeed that “black or white,” (we choose to stop it or we don’t), and that we as humans need, as an emergency, to commit ourselves to zero carbon emissions NOW. I did it this year. I vowed to move out of Los Angeles, and live on farms and new paradigm communities, while converting to wind, solar, and/or electric energy, the way I live in Maui, Hawaii, an o... show more

Agrophotovoltaik - Doppelte Ernte durch Solarmodule auf dem Feld


Quelle: deutschlandfunk.de

"Jeden Tag werden in Deutschland 61 Hektar für Siedlungs- und Verkehrsflächen freigegeben. Das entspricht ungefähr 85 Fußballfeldern. Flächensparen ist deshalb ein erklärtes Ziel der Bundesregierung – genauso wie die Energiewende. Die sogenannte Agrophotovoltaik könnte beides unter einen Hut kriegen."

Congratulations on the upcoming holiday - with Beltane, Walpurgis Night. Perhaps someone might think that it's late, it was May 1st. The point here is this: many people know that equinoxes and solstices fall on different days each year - this depends on many factors, primarily due to the fact that the calendar year (365 or 366 days in a leap year) does not coincide with the solar year (~365.24 days), but 4 other holidays from "Wheels of the Year" are traditionally celebrated on specific days of the Gregorian calendar:

Solar cells (like people!) work better with caffeine....Perovskite-based devices benefit from the strong bond between lead and the same chemical found in coffee and tea.
Scientists at the California NanoSystems Institute at UCLA have found that caffeine improves the stability of materials under heat,a property known as thermal stability,of perovskite solar cells, which could someday replace traditional silicon-based solar cells.For the past few years, perovskite solar cells have been thought to be the future of solar power because they could eventually cost less to produce than today’s silicon solar cells and they have the potential to be more energy-efficient. Research on perovskite solar cells dates back only to the early 2010s, but they are already nearly as efficient as silicon solar cells, which have been researched for more than 40 years.

China’s Solar Industry Expected To Be Subsidy-Free In 2021


Considering basically all energy producers reduce receive heavy subsidies, this is breaking in quite a new era...

China’s solar industry is expected to transition towards a subsidy-free market which could begin as early as 2021, according to a new analysis of China’s solar industry published by Asia Europe Clean Energy (Solar) Advisory.

The Asia Europe Clean Energy (Solar) Advisory (AECEA) published its new analysis last week, analyzing a new consultation paper published by China’s National Energy Administration (NEA) entitled Work Plan for the Construction of Unsubsidized (Grid-Parity) Projects for Wind & Solar PV. It follows in the footsteps of China’s efforts to revitalize its solar industry after it took a significant hit in May of 2018 when the NEA essentially capped installations.

“This signals a permanent policy shift towards zero-subsidy renewables,” explained Jonathan Luan, an analyst with Bloomberg New Energy Finance.

Agrophotovoltaics - Fraunhofer Reports Combining Farming With Solar 186% More Efficient In Summer Of 2018


For many people, solar power is seen as a threat to farming communities. That’s because they believe farmers must choose between raising crops or livestock and installing solar panels on their land. The Fraunhofer Institute has been conducting experiments in what it calls agrophotovoltaics for two years near Lake Constance, Germany. In the first year, it found the combination of solar and agriculture made the land 160% more productive than if it had been devoted exclusively to one or the other.

The Lake Constance farm mounts its solar panels 5 meters above the ground, leaving room for livestock and plants to grow and conventional farm equipment to operate beneath them. In comparison to open fields in the area, solar irradiation beneath the panels was about 30% less, the air temperature was identical, but soil temperatures in the spring and fall were lower.

So it seems with slightly different design combined with hotter climates, solar could well mean double benefits.

Origin of apparent light-enhanced and negative capacitance in perovskite solar ....So-called negative capacitance seems to remain an obscure feature in the analysis of the frequency-dependent impedance of perovskite solar cells. It belongs to one of the puzzling peculiarities arising from the mixed ionic-electronic conductivity of this class of semiconductor. Here we show that apparently high capacitances in general (positive and negative) are not related to any capacitive feature in the sense of a corresponding charge accumulation. Instead, they are a natural consequence of slow transients mainly in forward current of the diode upon ion displacement when changing voltage.

How farmers could help save South Africa from rolling blackouts


While the electricity price increases for the next three years are expected to negatively affect the agricultural industry, farmers have the capacity to run renewable energy projects on their farms to not only reduce their costs, but support the national grid. Eskom has announced tariff increases of 9.4%, 8.1% and 5.2% for the next three financial years.

Nicol Jansen, Agri SA chairman: economics, says farmers can apply to implement renewable energy for their own use, while remaining connected to the grid and feeding any additional power into the national grid. Farmers must register with energy regulator Nersa to do this, for an application fee of R200. “There are already about 400 farmer applications in the system and there is great interest in building solar capacity for this purpose,” he says.

Jansen notes that both Eskom and Nersa need capacity to process the 400-odd applications from farmers efficiently. “Once those applications have all been approved, we (the agricultural industry) could reach a targeted 1 000MW of power and it is quite possible t... show more

"The goals discussed above may be far too conservative, and progress toward 100% green energy will likely come faster than the Spanish government now envisages, driven as much by consumers’ desire to save money and improved efficiency and lower prices, i.e. by market mechanisms, even if the government becomes less ambitious."

Stromspeicher der PV Anlage


Ich hab gerade neue Zähler im Speicher meiner Batterie entdeckt.
Die Batterie nimmt Strom auf und gibt diesen ab. Und hat dafür auch absolute Zähler im Bauch.

Bisher wurden 301,445 KW/h insgesamt geladen.
und entladen wurden insgesamt 218,406 KW/h.

Macht einen Wirkungsgrad von 72,45%
