The solar yield calculator app of Vario green energy is now available for Android smartphones. An iPhone version of it already exists. House and roof owners can calculate with the free app on their mobile phone, which yield a photovoltaic power plant would generate and how much CO² they can save. Th

In order to calculate the possible yield of a photovoltaic system, the calculator depends on the average annual solar radiation at the site. The application determines the location via GPS tracking. Modern mobile phones detect tilt and orientation automatically when the device is lying flat on the roof. Motion control and compass functions make it possible. Alternatively, the user could enter all data manually.

For the calculation, the user could also combine other parameters, such as the module type, the type of the mounting system, the efficiency and performance of the system. He will receive an initial assessment, with which plant properties he could get the highest yield. All the results are approximate values.

"In addition to our existing iPhone app, even more smartphone owners will benefit from the new Android version in three languages," said Axel Fellhauer, managing director of the company in Holzgerlingen, Baden-Württemberg. "In this way, we want to inspire even more people to solar energy."
