About Rooftop photovoltaic energy storage capacity
The evaluation shows that China's rooftop PV generation potential reaches 6575 TWh yr −1, mainly concentrated in the eastern China, and that at least 90% grid flexibility and 8–12 h of storage capacity are necessary to achieve two-thirds PV penetration and meet the 5% curtailment constraint.

Between 2020 and 2021, there were 10.7% ($0.19/W) and 6.0% ($0.10/W) reductions (in 2020 USD) in the commercial rooftop and commercial ground-mounted PV system cost benchmarks respectively. Figure 6 and Figure 7 present the U.S. national benchmarks from our commercial PV models.
We start by simulating the storage capacity required for an extreme scenario where the rooftop PV potential in Jiangsu Province is completely developed and the PV curtailment rate must be zero. It is revealed that the storage capacity should be at least 0.64 TWh, 1.37 TWh, 2.94 TWh, and 4.97 TWh in a grid with 100%, 90%, 80%, and 70% system .
SETO funds research that helps maximize the value of rooftop solar systems for their owners. An example of this is solar-plus-storage, which consists of battery systems that store solar energy for later use.
