App for Optimizing Panel Angle Voltaic Systems September 9, 2014 All Voltaic customer Witold Wnuk recently created a Windows app to optimize panel angle. Rotate your phone along all three axes until a circle appears which you guide to the center of the screen. You should then match the panel angle to the phone for optimum charging. The angle and direction of the panel will vary based on how long you plan on charging (or repositioning), location and time of day. You can get the app here. We’ll be waiting for an Android or iPhone version. Leave a Reply Cancel Reply Your email address will not be published.CommentName* Email* Website This site uses Akismet to reduce spam.
