Batteries so cheap that solar doesn’t sleep: Solar electricity every hour of every day is here and it changes everything | Ember

1. Cheap batteries change everything, everywhere. 

2. Batteries are prohibitively expensive.

   Why evs are out of reach for a significant portion of the planet. Similar with solar. Looking at 150ah batteries and it’s $$$.

   Want me kw and it’s thousands.. so regardless on the way you phrase it. Cheap they are not

3. Cheap anything changes everything.

   If this is true and batteries can be made to meet demand, the main issue would then be making the panels.

4. The thing about this (and it’s great, of course) is that it’s specifically about “the sunniest places.” In Vegas, you need the batteries to get through the night and an occasional cloudy patch. Where I live in Seattle, you’d need the batteries to get you through winter. Compensating for season effects is *much* more expensive.

5. Yee-fucking-haw! Let’s go!

6. Already works for domestic installations in Australia. Long way off for industrial applications

7. Amazing to see this with today’s prices. Economies of scale will continue to compound, and hopefully someday the sunny areas can be efficient net exporters to their neighbors.

8. Okay. Where’s the 100% wind/solar/battery grid? Shouldnt have to wait until storage is cheap to see a experimental 100% renewable grid.

9. LOL, where I am, on some winter days, 6.4kW of panels struggle to generate 3kWh, and it can stay like that for several weeks. a 15kWh battery is not going to work for me.

   On a good summer day, said panels easily generate 45kWh.
