The article discusses how using solar power and batteries can make charging electric vehicles cheaper. By combining solar panels and batteries, the cost of charging an electric vehicle can be lower than using electricity from the grid. The study shows that using only solar power for charging is the most cost-effective option over the next decade. However, using a combination of solar power and batteries can be more expensive initially but becomes cheaper in the long run. This research supports the idea that charging electric vehicles with solar power and hybrid systems is a feasible and cost-effective option for the future.
