Solar+Storage/Impact on System Size
From Open Energy Information
Solar+Storage System Sizes
- 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.
