A recently released app is the first photovoltaic design software that uses cloud technology, according to EasySolar.
Taking advantage of cloud technology means that all PV projects are stored globally on the server, rather than on local devices. The data is accessible from any place and is processed very quickly, provided there is access to the Internet. Furthermore, the number of projects that can be saved in the app is almost unlimited.
The app is available from any device: smartphone, tablet, laptop. It works best on iOS, Android or Windows Phone platforms. Because different platforms are preferred in different regions, EasySolar app is written in Java language for Android, Objective-C for iOS and also C# and XAML language for Windows Phone devices.
An extended version will allow designers to create a final, professional report, thus enjoying more the result of the whole process of design. It makes use of the gyroscope, GPS and camera in the phone. For example, with the GPS function available in every smartphone, the app quickly finds the location to present irradiation data and other parameters for specific longitude.
The output data for the algorithm applied in the irradiation base is direct irradiation on horizontal plane for specific latitude and longitude. Horizontal, diffused and direct irradiation are provided by NASA resources. Numerous functions enable users to take a quick action while starting the designing process. Irradiation analysis made by the software is based on determining the correction coefficient that allows it to calculate the actual amount of solar energy arriving to the module with specific orientation and inclination. Furthermore, including all energy losses due to actual module temperature, dirt, and cables means that the simulation of output production is even more accurate. The optimal azimuth and inclination can be verified easily thanks to gyroscope properties.
A rooftop project can be designed based on the picture taken from the camera, therefore, no maps or technical drawings are needed at the conceptual level). With special algorithms, it does not matter from what angle the image was taken. This was unachievable in any other PV software up until now, the company claims.
