Solar Array Configuration Calculator

Solar Array Configuration converts the entered electrical measurements into total modules. Use it to the total modules calculation.

Enter values for total modules

Use one consistent electrical operating case for all fields.

Enter series modules in the displayed unit.

Enter parallel strings in the displayed unit.

How Solar Array Configuration works

This worksheet evaluates modules = series × parallel. Solar Array Configuration uses Series modules, Parallel strings to report Total modules.

With the loaded values, total modules evaluates to 30.00 modules. Compare low and high values without overwriting the starting case.

Inputs for Solar Array Configuration

Series modules and Parallel strings belong to Solar Array Configuration. Keep source units with series modules. Continue to Solar String Voltage Calculator for string voltage.

The sample case is a worked example, not a design target.

Series modules
Example entry: 10.
Parallel strings
Example entry: 3.

Reading the Solar Array Configuration result

This output represents Solar Array Configuration.

Apply required margins only after identifying the correct equipment standard. Use Off-Grid Battery Bank Calculator.

Measurement and units

Use site-specific irradiance, temperature, shading, equipment limits, and measured system losses. Check prefixes on series modules.

Do not compare cases built from different unit prefixes or measurement locations.

Limits of this calculation

Confirm string voltage and current limits.

Only the stated inputs participate in this simplified model. Unentered effects remain outside Solar Array Configuration.

Questions about Solar Array Configuration

What does Solar Array Configuration calculate?

Solar Array Configuration reports total modules.

Can Series modules be zero?

For Solar Array Configuration, measure any zero series modules directly.

Why can total modules differ from measurement?

Confirm string voltage and current limits. Recheck series modules.

Should the result be rounded?

Keep extra digits while comparing cases, then round to the precision supported by series modules.
