FAQS about 2021 photovoltaic energy storage

Did PV cost decline in the first quarter of 2021?

The 2021 PV cost benchmarks report found cost declines for PV-plus-storage and standalone battery energy storage systems (BESS). This graph shows how costs of standalone BESS fell significantly in the first quarter of 2021 compared to the first quarter of 2020. A major component of total installed system costs is the cost of the PV modules.
