With this App you gain: - Optimal Tilt angle for any desired location on the map - Optimal orientation - Optimal daily tilt angle - Optimal monthly tilt angle - Live Solar Tracking tool with hourly sun azimuth and altitude for any desired day, worldwide - Ideal tilt angle for any desired azimuth (premium feature) - On-site inclinometer for measuring angles - More solar tools for analyzing PV System - Map compass for accurate determination of roof (field) azimuth - Satellite map view
The tilt angle of the panels is one of the most important parameters for your PV system. It is the angle at which the photovoltaic panels are set to face the sun relative to a horizontal position. The panels must have appropriate tilt angle set for gaining maximum possible electricity from your PV system for your location. Optimal Tilt is using optimization model for obtaining the most ideal tilt angle of your panels in order to gain maximum electricity generation from your system.
The model is based on sophisticated methods for maximizing energy yield with finding the best performance for any desired location.
The additional tools and apps can help you optimize your PV System and check the performance including financial implications.

Comments on Optimal Tilt Angle - PV System for Android
★★★★★Michael Garrison· Feb 6, 2025
Gives accurate angle information for your zip areas on the fly. Plan on using app for initial solar panel adjustment and fine tune (if needed) with a shadow gauge.
★★★★★Michael Z (MikeyLikesIt)· Mar 18, 2025
Easiest tool to use and has everything you need for setting your solar panels correctly. Well worth the 7 bucks for premium lifetime.
★★★★★Syed Sujathulla· Nov 6, 2025
App is useful only if we select location on map, on its own won't show the correct tilt or when it is first launched after giving permission to location, wish in clinometer button appears on the clock type in clinometer page.

Ads ads that take over the screen. Uninstalled.

Beyond dumb. I should be able to sit my phone on my panel it tells me how to orient it for best sun
★☆☆☆☆Martin Davies· May 11, 2025
I don't understand the 4.9 rating. Everything which might be useful is locked in the pro version. Free version gives me the tilt angle for a location thousands of km away and requires me to manually drop a pin nearby, then gives an angle reading but no compass readout.

UPDATE: Changing to 1 star because after emailing the author, no response. Contacted a second time, still nothing. I'm giving this 2 stars because functionally it is very nice, but in terms of accuracy they need to check their calculations and algorithms. I sent a contact form from their website notifying them of the glitch that I found in the monthly solar elevation data.
