many companies are exploring drone delivery to get the job done. In areas where the power grid has been leapfrogged by home solar, solar-powered drones can be the final link in the supply chain, safely and reliably depositing orders directly to consumers — no roads or fossil fuels necessary. Each rooftop panel could become a charging station for delivery drones. The drones can make deliveries throughout a region while stopping to recharge on homes with charging stations connected to solar panels. Without having to go back to its home base, the deliveries are faster, more efficient, and cheaper. Plus, the customers get credit for the power that the drones sip from their panels.
