oTilt is an online tool for quickly determining the optimum tilt angles for solar collectors. Site can be located in an integrated Google map, searching it using keywords (e.g. Central Park, New York) or by directly entering latitude and longitude. oTilt determines the optimum monthly, seasonal, half-yearly and fixed tilt angles for solar collectors at selected site location along with respective energy collection during these spans. Results are presented in the form of a table. Screen Shots
