Solar sizing for homes, business & industry · inverter, battery & PV from 1 kW to 1 MW

Industrial solar sizing
Megawatt thinking, engineering discipline.

Process loads, motors and long shifts need a design that respects surge and three-phase supply. Get a first sizing in minutes, then take it to detailed engineering.

Typical loads we size for

  • Motors & compressors
  • Pumps & irrigation
  • Process heating
  • Conveyors
  • Cold rooms
  • Workshop tools
  • Site offices
  • Lighting towers

The approach

Sized from what you actually run.

01

Three-phase aware

Choose single or three-phase supply and the inverter selection is steered by it.

02

Motor surge accounted for

Large motors start at several times their running current. The inverter is checked against that surge, not only the running kW.

03

Transparent formulas

Every result shows the working behind it, including sun hours, derate, efficiencies, depth of discharge and ageing, so an engineer can check it line by line.

04

Clear review flags

Above the residential band the result carries an engineering-review flag, so a first estimate is never mistaken for a final design.

Four steps

From load list to bill of materials.

  1. 01

    Choose the site

    Home, office, commercial building or industrial plant — then start from a ready scenario or a blank list.

  2. 02

    List the loads

    Appliances with quantity, power and running hours, split between sun hours and night. Or import a spreadsheet.

  3. 03

    Set backup & supply

    Grid-tied, hybrid or off-grid, single or three-phase, generator or not — and how long the essentials must run.

  4. 04

    Get the system

    Inverter, battery and array, string layout, matched products and a bill of materials — saved and shareable.

Industrial FAQ

Good questions.

Is the result a final design?

No. It is a fast, transparent planning estimate. Confirm every design against the manufacturer datasheets, a site survey and your local wiring regulations before you build.

How does it handle diesel generators?

Choose a system type with a generator and the engine accounts for it as a backup source alongside the grid and the battery.

Can I change the design assumptions?

Yes. Efficiencies, depth of discharge, end-of-warranty capacity, inverter loading and design margins can be changed for each sizing, within set bounds.
