North America currently has over 20 GW of installed utility-scale PV generation. With 2016 seeing the largest amount of PV installed to date with over 14 GW brought online. The majority of this installed utility-scale PV base could expand production hours and increase revenues with the addition of energy storage.
Here we will examine the coupling of energy storage with PV by comparing three principle methods: AC-coupled, DC-coupled, and hybrid solar-plus-storage inverters. We will also consider all possible revenue streams of solar plus storage and their availability based on available systems for coupling storage.
