Solar Loss Chain Calculator

WHATSON / SOLAR & BATTERY

Solar Loss Chain Calculator

Multiply successive loss factors and see how each stage changes energy.

Starting values are editable examples. Enter your own loads, datasheet values and site assumptions.

Successive 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.

01 / GET STARTED

How to use Solar Loss Chain Calculator

  1. Enter energy before losses.
  2. Add the entries in sequential loss stages as separate rows. Include stage and loss at this stage for each row.
  3. Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
02 / A CLEARER WORKFLOW

Why choose this tool?

The stage by stage view explains how an initial energy amount changes along the chosen path.

Before you use 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.

03 / COMMON QUESTIONS

Questions about Solar Loss Chain Calculator

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.
