Excel File Sheet Solar Power System Design Calculator

Sizing a solar system by hand means juggling panels, batteries and inverters across five spreadsheets.

Every project repeats the same routine: collect the inputs, run the checks, format the output. This workbook compresses that routine into a single reusable file — start from a working template instead of zero.

At the heart of the template

Enter system voltage, daily sunshine hours, and electrical load details

Calculates the required solar panel array size in watts based on the load

Allows selecting the solar panel voltage and configuring panel strings

Shows total number of solar panels needed

Specify battery bank voltage, reserve days, depth of discharge, efficiency

Calculates battery amp-hour rating and number of batteries required

Made for

Solar installers, electrical engineers and energy consultants sizing off-grid and hybrid PV systems.

Why it works on real projects

Instant delivery — arrives right after your order.

Clear, documented logic — check every step yourself.

Reusable every project — build once, adapt as needed.

Proven — 9 engineers own this workbook already.
