Common questions
Can I use this solar panels calculator for different panel sizes?
Yes. Enter the rated watts of one panel to compare panel counts for the same daily energy target. This solar size calculator sizes an array by energy demand; it does not check roof fit, module dimensions or electrical string compatibility.

Abans d’utilitzar el resultat
Peak sun hours are equivalent full-sun hours, not daylight hours. Use a location- and season-appropriate value. Losses should reflect temperature, shading, wiring, conversion and any battery cycling. This energy balance does not guarantee uninterrupted off-grid supply.
Why are panels rounded up?
You buy whole modules; the installed array may exceed the calculated minimum. Check inverter PV capacity and string limits.
