Opti Solar: Panel Angle

Find the right angle for your solar panels before you install or adjust them.

Opti Solar helps you measure panel tilt, true azimuth, shadows and expected production directly from your phone. Use it for rooftop,

balcony, garden, RV, van, boat, camping and off-grid solar projects.

MEASURE ON SITE

Place your phone on the panel to read tilt angle and direction. The smart compass warns you about magnetic interference, and reference

locking lets you compare measured values without guessing.

CHECK SHADOWS

Shadow Hunter helps you measure trees, chimneys, walls and nearby buildings, then see when they may shade your panels through the year.

VIEW THE SUN PATH

Use augmented reality to see the sun path in the sky and compare seasonal positions.

ESTIMATE PRODUCTION AND SAVINGS

Get a Solar Score from 0 to 100, estimate yearly output, calculate savings, payback time and self-consumption, and adjust electricity

prices to your situation. Estimates use climate zones based on PVGIS, NREL PVWatts and NASA POWER data.

PLAN AND DOCUMENT

Map usable roof area, follow seasonal tilt recommendations, track monthly production, and export simple, detailed or pro PDF reports for

your records, installer discussions or client files.

Opti Solar is a planning and measurement tool. It does not sell solar panels, does not connect automatically to inverters, and does not

guarantee production. Accuracy depends on your phone sensors, GPS quality and magnetic interference near the panel.
