A country collectively too stupid to operate, the sum more ignorant than the parts.

Caught between a rock and... Nevermind.

AQI was 107 in Taipei, American neocons used to rip into China for their horrendous AQI.

Does someone here have opinions on salt based batteries? For home use with #photovoltaics on the roof.

I found https://www.salzstrom.com/category/all-products which seems to be as available as the lithium ones. Prices are also not that far off.

Much longer lifetime as well as not being lithium based seem to be a huge benefit.

March solar stats

South facing 5kwp array, 5kw inverter and 2x15kWh batteries in the west of Ireland

Solar total 363.2 kWh
Grid Import 405.5 kWh
Grid Export 239.4 kWh
Grid total 166.1 kWh

Imported energy cost €23.32
Exported energy return €58.12
Total energy cost -€34.80

I'll endeavour to get all the data into a spreadsheet so I don't have to copy and paste stuff, which is a pain on a mobile phone.

Very nifty approach!

"Perovskite solar cells (PSCs) with power-conversion efficiencies comparable to established technologies hold huge promise for becoming the future photovoltaic technology, also given their versatility, low-cost and energy-efficient fabrication processes. However, PSCs are not stable under moderate reverse bias, an unavoidable situation under real-world operation, for instance, caused by partial shading of a module or installation with PSCs connected in series. Approaches to address this issue have focused on engineering the device architecture to enhance the breakdown voltage and mitigate the detrimental effects of reverse bias2,5,6. Here we present a completely different approach that fully solves the reverse-bias issue. With our Memsol, we developed a new concept of a solar cell with an integrated memristor, which protects the solar cell and simultaneously works as a bypass element. The memristor is realized by area-selective deposition of an additional metal–insulator stack and shares the perovskite and electrodes with the solar-cell part. Reverse-bias and shading tests show that the Memsol remains stable and automatically toggles between a low-resistance bypass state and full-efficiency solar-cell operation, dependent on the illumination and bias conditions."

Dr Gilbz spells it out. The #climate scientists were a bit too conservative. #climateChange denial is strong in the US these days, but if it provides any comfort, please know many of us are still doing our best, regardless. I’m putting up more #photovoltaics this summer. Rebates be damned.
