Description
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.
INCLUDED TOOLS - Solar panel tilt and compass measurement - Production estimate - Solar Score - Financial simulator - Seasonal calendar - Simple PDF report
PREMIUM ONE-TIME UPGRADE - Shadow Hunter shading analysis - Full AR sun path - Roof mapping on satellite map - Energy monitoring with charts and alerts - Detailed and pro PDF reports - Installation certificate photo
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.
