Evaluating the Technical and Economic Performance of PV Plus Storage Power Plants: Report Summary

LCOE is a incomplete metric for evaluating PV plus storage because of the significant increase in value associated with storage—benefit/cost ratio is an alternative metric that accounts for the added value. Coupling by co-locating storage and solar can decrease the overall net costs of deploying PV and storage (AC coupling).

Go big, go DC: an in-depth look at DC-coupled solar-plus-storage

Using the example of a 100MW AC inverter connected to a 130MW DC solar array, the plant''s output is 100MW, resulting in many megawatt hours of clipped energy annually. Connecting energy storage to the PV array by DC coupling allows for the PV-to-inverter ratio to be significantly increased, and output otherwise clipped and lost in
