How to Estimate Solar Panel Output
Wanneer dit van toepassing is
Use this guide for early PV screening when you need an order-of-magnitude kWh estimate and explicit loss assumptions before vendor curves or full shading models.

- 1Start from module nameplate DC power and expected peak irradiance at the site.
- 2Apply temperature, mismatch, soiling, and inverter efficiency derates you can defend in a note.
- 3Convert DC energy to AC using inverter efficiency and clipping assumptions if relevant.
- 4Compare seasonal tilt or tracking differences only after the baseline fixed-array estimate is clear.
- 5Escalate to hourly simulation when shading trees, roof obstructions, or complex tariffs dominate.
Voorbeelden
- Residential roof screening before requesting installer quotes.
- Off-grid array sizing next to a load profile estimate.
Vermijd dit
- Using STC nameplate power without temperature derate in hot climates.
- Confusing DC array output with usable AC energy at the meter.
- Ignoring inverter clipping on small batteries or strict export limits.

Veelgestelde vragen
Does this replace PVsyst?
No. It frames transparent assumptions for quick decisions, not bankable production reports.
Can I use PSH only?
Yes for first-pass checks, but document the PSH definition and seasonality you used.
