NORTH AMERICA currently has tens of gigawatts of installed utility-scale PV generation with many more gigawatts under construction. Utility-scale solar will only reach its fullest financial and energy generating potential with the addition of energy storage, however. The majority of utility-scale PV base could expand energy production and increase revenues with the addition of energy storage. Choosing the right topology is critical to maximizing the impact of coupling energy storage with utility-scale solar installations.
