Solar+Storage System Sizes

Key Questions

  • What is a typical solar+storage system size for my building type?
  • What is the impact of declining technology costs on optimal system sizes?

Explore optimal system sizes for different building types and locations using the interactive charts below.

  • Average system sizes increase with declining technology costs.
  • Optimal battery capacity increases with building load, especially at lower technology costs.

Average System Sizes for Commercial Buildings where Solar+Storage is Economical

as determined through cost-optimization modeling
(average of all cost points)


As a rule of thumb, a 10kW solar PV system would require about 1000 square feet of roof space. A 1MW ground mounted system would require approximately 6 acres of land.
