Solar Shading Loss Calculator

How Solar Shading Loss works

The result comes from energy = baseline × (1 − shading loss). Solar Shading Loss uses Unshaded energy, Shading loss to report Energy after shading. Suggested inverter rating belongs in the separate Solar Inverter Size worksheet.

With the loaded values, energy after shading evaluates to 20.64 kWh. Keep other entries fixed when exploring a measurement range.

Inputs for Solar Shading Loss

Unshaded energy and Shading loss belong to Solar Shading Loss. Keep source units with unshaded energy.

Treat the preset entries as an arithmetic example. Supply measurements or ratings from the actual circuit.

Unshaded energy

Example entry: 24 kWh.

Shading loss

Example entry: 14%.

Reading the Solar Shading Loss result

This output represents Solar Shading Loss.

Do not treat the calculated number as a component rating by itself. Check standard sizes, transients, protective margins, and manufacturer limits. For autonomy duration, use Solar Autonomy Calculator.

Measurement and units

Use site-specific irradiance, temperature, shading, equipment limits, and measured system losses. Check prefixes on unshaded energy. Array power can be checked in Solar Irradiance Power Calculator.

Keep the same electrical reference points across saved cases.

Limits of this calculation

Electrical mismatch can make shading loss nonlinear.

The arithmetic is intentionally narrower than a complete circuit model. Unentered effects remain outside Solar Shading Loss.

A useful Solar Shading Loss comparison

Record energy after shading before testing a different unshaded energy value.

Document the alternate unshaded energy source. Use MPPT Voltage Window Calculator to a separate available voltage margin calculation.
