Energy before losses
Starting energy · kWh
Allowed range: 0 to 1000000000
Solar Loss Chain Calculator
Multiply successive loss factors and see how each stage changes energy.
Open this toolSuccessive losses act on the energy remaining after the previous stage. Adding every loss percentage can misstate the result.
List the energy path and enter each stage once. Include battery losses only for energy actually routed through storage.

How to use
- Enter energy before losses.
- Add the entries in sequential loss stages as separate rows. Include stage and loss at this stage for each row.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why use this tool
The stage by stage view explains how an initial energy amount changes along the chosen path.
Before relying on the result
Percent losses act on the remaining energy at each stage. Include a battery stage only for energy routed through the battery; direct solar energy should not incur it.
Tool limitations
Percent losses act on the remaining energy at each stage. Include a battery stage only for energy routed through the battery; direct solar energy should not incur it.
Questions
Should direct solar energy include battery losses?
Not if it bypasses the battery. Model the path the energy actually follows.
What should I check before using Solar Loss Chain Calculator?
Check Energy before losses, Stage and Loss at this stage. Use the exact units shown beside the controls and replace any example values with your own inputs.
