Simple tilt angle protractor free application that can easily measure tilt simply by tilting the device. The angle of inclination measured from 0 degree to 359 degrees, converted gradient (%), angle at which sum is 180 degrees / 360 degrees are displayed at the same time. You can switch to the theodolite, the specified angle can be set to 0 degree. ( 45 Degrees = Gradient 100 % )

Simple and accurate determination of the optimal PV tilt angle. Make your PV System generates 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 this App you will obtain: - Solar Data charts (elevation, azimuth, sunrise, sunset time, noon time, sunlight duration, etc.) - Tilt vs azimuth optimization (find the ideal tilt angle for any chosen azimuth) - Optimal Tilt angle for any desired location on the map - Optimal orientation - Optimal monthly tilt angle - Optimal daily tilt angle - Optimal hourly tilt angle - On-site inclinometer for measuring angles 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. PV Solar Tilt is using optimization model for obtaining the most appropriate tilt angle of your panels in order to gain maximum electricity generation from your system. The model is based on sophisticated simulations for maximizing energy yield for a given location. If you need any assistance or clarification, please let us know at support@pvsolcast.com.
