Comments on Optimal Tilt Angle - PV System for Android

★★★★★ Hamid Mahmood Ahmed · Jan 30, 2026

This is a very nice application helpful for lots of people like me. We can use this application to find the optimum angle for the best use of solar system.

★★★★★ John Keil · Oct 3, 2025

I used this app to set up my solar panels while camping. Very convenient and accurate.

★★★★★ 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.

★★★★☆ Peter Collins · Dec 30, 2024

Doesn't do live angle calculations and sun tracking seems stuck at gmt+0. Annual and monthly calls correct for location though

★☆☆☆☆ 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.

★☆☆☆☆ Emery-n-Denise's Golden Puppies · Mar 24, 2026

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.

★★☆☆☆ Glen O · Mar 25, 2026

Beyond dumb. I should be able to sit my phone on my panel it tells me how to orient it for best sun
