Berlin-based climate research institute Mercator Research Institute on Global Commons and Climate Change (MCC) has released a new study indicating that, in the last decade, the cost of solar power has dropped by 87 percent, and the cost of battery storage by 85 percent.
Batteries definitely do not cost the same.
Well that’s a compelling case you make there.
Have a counterpoint:
Solar battery average price in 2018 was $10k for 10kw Its now $12k for 10kw.
So you’re actually right! The price has increased.

Now do again with the same manufacturer and minus the ridiculous inflation we had in the last couple of years.
You are comparing the average to a high end.
