Boat solar mounting shadow comparison calculator

Calculate observed daily yield by option and highest-yield option with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use observed daily yield by option and highest-yield option to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Observed daily yield by option (Wh)

Piecewise measured yield=unshaded hours×power+shaded hours×power.

Highest-yield option (1-based)

Piecewise measured yield=unshaded hours×power+shaded hours×power.

Assumptions & limits

Assumptions & limits

  • Uses supplied measurements only; no sun-position, panel-string or partial-shade electrical model. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Uses supplied measurements only; no sun-position, panel-string or partial-shade electrical model.
