Solar Generation Estimator

Estimate AC energy after separate DC losses and inverter efficiency.

Starting values are editable examples. Enter your own loads, datasheet values and site assumptions.

Solar & Battery

Solar nameplate capacity becomes usable AC energy only after the entered production and loss assumptions are applied.

Set sun hours, DC losses and inverter efficiency separately. Check whether an existing yield factor already includes one of those losses.

01 / GET STARTED

How to use Solar Generation Estimator

  1. Enter DC array capacity, peak sun hours and period length.
  2. Enter DC side loss allowance and inverter conversion efficiency.
  3. Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
02 / A CLEARER WORKFLOW

Why choose this tool?

Separate stages make the estimated output easier to trace and reduce accidental double deductions.

Before you use the result

DC losses and inverter efficiency are multiplied separately. Do not enter a combined AC loss here and deduct inverter losses twice. No weather or city data is fetched.

03 / COMMON QUESTIONS

Questions about Solar Generation Estimator

Does the tool fetch city weather?

No. Sun hours are entered by you. Use a suitable source or measured record for the planning location and period.

What should I check before using Solar Generation Estimator?

Check DC array capacity, Peak sun hours, Period length and DC side loss allowance. Use the exact units shown beside the controls and replace any example values with your own inputs.
