The evolution of PV and PV+storage installation costs in the US in 2020
The cost of solar and solar+storage fell by an average of 10% betweenQ1 2020 andQ1 2021 in the US.
NREL examined the evolution of installation costs, taking into account all system and project development costs.
Large plants :
The cost of a 100 MW single-axis solar plant for a utility decreased by 12.3% from $1.02/W-dc to $0.89/W-dc.
The cost of installing a 60 MW/240 MWh stand-alone battery energy storage system (BESS) decreased by 13.1%, from $437/kWh to $379/kWh.
A 100 MW PV system + 60 MW/240 MWh DC battery decreased by 11.5% from $190 million to $168 million.
A 100 MW PV system + 60 MW/240 MWh AC battery decreased by 12.3% from US$190 million to US$167 million.
Commercial installations :
The cost of a single 200 kW solar installation decreased by 10.7
The cost of a 600 kW / 2.4 MWh single battery installation decreased by 10.6
The cost of a 1 MW DC solar installation and 600 kW / 2.4 MWh storage decreased by 9.2
The cost of an AC solar installation and storage decreased by 9.5
Residential installations :
The cost of a 22-panel system decreased by only 3.2
The cost of installing a single 5 kW / 12.5 kWh battery has decreased by 9.7
The cost of a residential DC solar system with storage decreased by 5.8%,
The cost of a residential AC solar system with storage decreased by only 3.4%.

Editor's note: We would like to see comparable estimates made in France. It is abnormal that our country does not have data on what is going on within it. Unless this obscurity favours the players in place!
