Storage screening
Storage decisions need interval evidence.
Rated capacity describes equipment. It does not establish dispatch value, savings, or resilience at a site.
Reviewed 2026-07-14Equipment values shown
Rated power and rated energy determine duration. The calculation applies an 85 to 92% round-trip-efficiency assumption and reports an upper bound on energy available to shift per full cycle.
Why annual savings are suppressed
Annual totals cannot establish coincident solar surplus, peak demand, cycling, tariff value, dispatch, or degradation.
Backup runtime is not calculated.
Study inputs
Estimating annual savings requires interval and site evidence.
- Interval load
- Interval solar
- Demand tariff
- Outage objective
- Interconnection
- Safety and code review
- Degradation and warranty
