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.
Rooftop systems are the most expensive way to do solar. I know everyone likes the idea of sticking it to the power company, but it does need to be deployed at scale to see the savings.
We should be encouraging community solar, where fields of panels are owned by the community.
