About this app

If you don't have a PV System yet: The easiest and cheapest way to go solar: https://www.energysage.com/p/mspe

Simple and accurate determination of the optimal PV tilt angle. Make your PV System generate maximum electricity for your desired location. The wrong position of your PV System can cause losses in electricity generation and your project feasibility may be a question.

With the solar tools we have optimized more than 400.000 Photovoltaic Systems worldwide, including rooftop solar, ground mounted PV Systems and large-scale photovoltaic power plants. Our tools are trusted by more than 150.000 satisfied users. Play Store rating: 4.7.

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
- 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.

Instead of pushing for premium. They should make app work a bit better. What is the point of asking for GPS access if you going to leave my location in Africa? When gain access it should have auto adjust sand save. You need to go open menu. Then map.. Then force the red pin to adjust. It is a tap not a hold. Then the map won't let you do basic things like point north. They are already pushing ads. Should at least give us basic functionality

Input jumped from 2.1A to 6A incoming at peaks seconds after orientation using the app. Looks like the hail (last month) knocked the panel (pole mounted) out of orientation. It's backup for the radio and when power was knocked out last night, the batteries lasted an hour and a half. These guys thought their batteries were bad but in reality they weren't really charging. Hopefully during the next storm they don't lose comms. I wasn't supposed to work this weekend but you got 5 stars from me. 👍

I love the simplicity of the app. Thank you for understanding that the traditional optimum angle is not THE optimum angle. My issue is that after swiping around on the app, it finally used my location and the optimum tilt made since. I can not, though, get the monthly tilt angles to update to my location. Even though the correct position is listed at the top of the page, the angles do not agree with the optimum tilt given on the first page. Please fix because this is just to handy to not use it.

Hello Robert, Thank you very much for your valuable feedback. After choosing your desired location on the map, you have to pass to the first screen and double click the gauge in order to refresh the optimum angle for the chosen location. We are aware of this mini bug and are working towards fixing it. Thanks again. Kind regards, NRG Labs

What's new

✔ Added annual and daily optimal tilt angles for different azimuths (0-360)
✔ Bug fixes.
✔ Performance improvements.

Thank you 😊
