Would a solar system on my roof be worth it? In the future, European futurists can use Google Sunroof to save money by generating clean electricity.
Google’s Project Sunroof is coming to Europe. Group has joined forces with E-ON, a major European energy supplier. The software [as a service] can be used free of charge on the website of E-ON Solar. It first calculates the roof surface of a given address, and gives an estimate on the power and the profit for the owner of the solar system.
Project Sunroof was launched in the USA in 2015, but operates as an independent platform without a partner provider. The software uses the map data available through Google Earth Simulation and its navigation algorithms to locate locations. The size and shape of the roof is calculated using a 3D model of the given building. Possible locations for solar plants are shown in yellow color. In addition, Project Sunroof uses local weather data to determine the efficiency of a solar system.
Less than 30 percent of households in Europe are covered
Using this data, the software calculates the theoretically achievable output in kilowatt hours of a solar system. Out of this, the annual revenue is calculated in Euro. In USA, the area coverage of this tool is limited to densely populated areas. According to Google data, nearly 7 million, or about 40 percent, of all households are also covered in Germany.
Cities such as Berlin or Hamburg are covered on a large scale, as is shown by a short trial of the software. For rural areas, however, there is little or no information. Particularly in areas where there are several single-family houses, having their own solar systems is a rather difficult question to ask.
Whether the software will start showing information on the missing regions is unclear, but it is not unlikely. The expansion of Sunroof to other countries shows the success of this project, but Google does not make a profit, a Google spokesman said. The program is free of charge even for providers to which it refers, including E-ON, for example.
