How much solar power will the world install eventually? 10 terawatts? 64? Or maybe something astounding like petawatts once our Dyson sphere gets moving.

In the shorter term though - the Solar Overton Window is widening - and a terawatt per year of capacity in nigh. Image I wrote a short article on this widening window, and it feels hopeful.

‘* SAYS BY SEPTEMBER 1, AMOUNT OF STORAGE CAPACITY ADDED TO GRID SINCE PRIOR SEPTEMBER PROJECTED TO REACH 4,302 MEGAWATTS (MW)’

Anyone know the connected value last September? I’ll go look… marketscreener.com/news/latest/Ca… Here’s the document referenced by this press release

“pilot production line for perovskite-based PV cells is expected to be operational at the factory by late 2024, with a view to producing commercially viable Perovskite cells by 2026”

@solar_chase Current perovskite+silicon record cell is 33.2%

Solar and Solar+2 hours of storage paybacks modeled, includes model assumptions, of the California PUC proposed NEM 3.0.

Models seem to incentivize projects more at 50% of load, with two hours of batteries - 5.6 to 7.9 year paybacks for Residential.

docs.cpuc.ca.gov/PublishedDocs/… Commercial paybacks modeled in the 6.0 to 7.9 across the utilities and solar through solar+storage. No label on whether this is new or old model.

2022 Global Solar Capacity Installation Projection Thread: A collection of professional projections by the likes of @BloombergNEF, @IHSMarkit, @WM_PowerRenew, @SolarPowerEU, @PvInfolink, @PaulaMints1, and even the @IEA - plus whatever else I think is cool and fits in the thread. As of November, @BloombergNEF's public number was that the world may install 211 GW of solar power. This is the middle range, and very well could end up being higher.

I think @solar_chase said 2021's number ended up being 183 GW.
