INTERACTIVE SOLAR CALCULATOR

Build Your Preliminary Solar System Estimate

Use the solar system calculator to assess residential, commercial, industrial and remote-site electrical loads using visible engineering assumptions

Zubicon Solar Sizing Calculator

Use actual equipment nameplate data whenever available. Default appliance values are only preliminary starting points.

Project profile

Select the closest project, system type, GCC location and electrical supply.

Project application
Intended solar system
Qatar is the default. Local grid and authority requirements must be verified.
Select “Not sure” when the meter or main distribution board has not been checked.

Electrical appliance loads

Add each major load. For air conditioners, pumps and motors, enter electrical input power—not cooling tonnage or horsepower alone.

How the Solar System Calculator Derives the Estimate

The solar system calculator separates connected load, daily energy, PV capacity, inverter demand and battery storage instead of producing one unexplained result.

 

Load and energy

Each appliance contributes running power and daily energy according to quantity, hours and duty cycle. Peak demand is evaluated by selected usage period.

Energy = Watts × Quantity × Hours × Duty ÷ 1000

PV array

The selected share of daily energy is divided by site solar resource and a visible performance ratio that accounts for system losses.

PV kWp = Target kWh/day ÷ (PSH × Performance Ratio)

Battery storage

Only selected critical loads are included. Backup hours, depth of discharge, inverter efficiency, battery efficiency remain editable.

Battery kWh = Backup Energy ÷ (DoD × Efficiencies × Factors)
