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.

Currently running 8kWh of lead-acid which as we know might as well be around 3kWh usable. Going to lithium would really make a car out if it, but the car itself is a weird old thing and not worth much so I don’t want to invest a ton into it.
