It did what I wanted it to do: It showed me the levels of efficiency in changing variables like the angle, placement, time-of-year, and direction my panels were facing.

This is the best android app for analyzing the best placement and tilt of solar panels, taking into account shadi g throughout the year. Not very intuition though. Search YouTube for the app and watch their instructions before attempting.

works great. however the scan the horizon feature makes no sense and has no explanation

Some fantastic functionality for a free app! Easy to use and good documentation.

Wow, useful? Immensely, perfect would be, adding in ROI calculations, figured from known kWh usage

Really great tool for investigating solar potential in particular place. Addition: It would be great to display numerical values for current tilt/azimuth along with effectiveness percentage.

Worked easily and gave very believable result in Australia. Very useful results.

Very useful, thanks!. Worked perfectly with my Galaxy Note 2, though a little difficult to see the instructions with the sun shining on the screen. A couple of requests if I may?, 1, the yellow dialogue boxes are almost impossible to read, especially outside, please change the colour. 2. Would be great if a shot of the shading horizon with the sun track range of winter and summer could be saved along with the analysis output.

I checked out of 5 other applications in this field. ScanTheSun outclasses them all at once and individually! To be honest it is a shame that all these applications must be placed on one rating scale, because it almost provokes the author of this miracle;) Taking into account the geographical location, terrain, circular and rotational movement of the Earth. Determining the terrain and obstacles, determining the percentage of panel performance depending on the location presented in a beautiful colorful sphere. Masterpiece!. Additional diagrams of daily energy production broken down by months and determination of the accuracy of operations up to 2055! EVERYTHING in this application is thought out and in place! If I buy a house, in 20 seconds I will know how profitable it is to install solar panels on it. I will not have to rely on the opinions of “experts” 🙂

It is excellent! …. very useful! The only problem is when using a previously created shadow horizon, it is almost always displaced from the true horizon and the question of which was the best measurement remains. It is surely due to the calibration of the sensors and the compass. It would be very interesting to add an option to download in a .jpg file the image of the shadow horizon, with the solar trajectory, the hour quadrants and the information of sunrise and sunset times behind the objects that provide shade. I congratulate you, excellent work!

What you gain from SCANTHESUN

Reduce installation costs and shorten payback period

Arrange the panels in the direction where there is the most solar energy

Reduce the impact of shading by surrounding trees and buildings

Design recommendations and key information for your solar installation, such as:

Energy map

A map of solar energy on the surface of the property and the places with the greatest potential for energy yield.

Arrangement of panels

Proposal for placement of PV panels on the building, taking into account window chimneys and other obstacles. Minimization of investment costs due to the ability to choose the number of PV panels and placement in areas with the highest energy yield. Immediate creation of a comprehensive online report available to the investor and installer.

Energy yield forecast

Projected energy yield from the planned solar installation. Energy yield for the whole year, for the selected season and for individual months. Total energy yield or yield per square meter of area. The projected output of the installation on an hourly basis for each month, including hours of shading.

Impact of the installation environment

The influence of the environment in the form of terrain, neighboring buildings or trees on the operation of the solar system.

Atmospheric conditions – NASA

The impact of local atmospheric conditions on energy yields by using NASA satellite data.

Panel efficiency and optics

Effect of efficiency and optics of solar modules on energy yield in a given installation environment.

Sunlight hours

Hours of sunlight for the various parts of the building and hours of shading. The amount of solar energy available for each section of the property.

Best positioning of panels

The best positioning to place solar panels on the ground or on parts of the building taking into account the installation environment. You will minimize the impact of shading and associated energy losses.
