It’s time to scale. The killer feature of solar + batteries is what it doesn’t have – moving parts. This means that uniquely, solar + batteries can be modularly engineered and scaled without loss of efficiency. Its actually more efficient to locate them as close as possible to the consumer.
Large centralized solar, wind and fossil fuel energy will always be tied to the grid with its associated cost of transmission, power management and off take agreements.
Avoiding all these will afford solar + batteries the position of dominant technology for energy generation, storage and delivery over the next decade.
