At optional step 208, a modification to the installation scheme is received from the user. The system allows a user to manually draw and set buildings and obstacles on the 2D positive shot map, and when the user draws, the system automatically recognizes and displays information such as building size, building area, building azimuth angle, building gradient angle and the like.
At optional step 210, the geographic location of the building is determined. For example, GPS positioning data or electronic map data may be invoked to obtain geographic location information.
In optional step 212, historical weather data is obtained for the area in which the building is located. For example, a weather database may be invoked to obtain historical weather data for the ground, such as average sunlight time and average sunlight intensity, and so forth.
In optional step 214, the power generation of the solar power plant is determined based on the geographic location and the historical meteorological data and the installation plan. The power generation amount may be calculated, for example, according to the corresponding calculation formula.
In optional step 216, the installation scheme is adjusted to maximize the power generation. The server may, for example, optimize the installation scheme based on related data such as geographical data of the building and historical meteorological data, adjust the position or orientation of the solar power station based on light conditions, select a corresponding make or model, etc. After the optimization is finished, the generated energy is recalculated. The optimization process may be iterated multiple times until an optimal result is reached.
