For large-scale grid storage, pumped hydro is the most cost-effective option, but at smaller scale, this technology is not competitive with batteries. This investigation set out to find the crossover size at which batteries and pumped storage have similar overall costs, when used for off-grid communities.
Solar generators are portable battery storage systems powered by solar panels. Unlike solar-plus-storage systems, solar generators are not designed to back up major appliances in the event of an outage. You can compare solar generators by assessing the watts and watt-hours of the systems, as well as their battery chemistries.

The centralized generation has also lower flexibility to failures, than the distributed one. As if a relevant fault occurs in the plant, a big portion of the generation power could be turned off, with relevant impacts in the dispatching and with possible power interruptions for several final users. An Overview of Distributed Vs.
