What determines the output of a solar energy system?
The output of a solar energy system is primarily determined by the efficiency of the modules as well as the size, orientation and location of the system. Final output is then influenced by additional factors such as: The weather: While the modules will still produce even when the sky is cloudy or foggy, the panels require direct sunlight to produce any significant level of power. Clouds will cut the level of output significantly. Shading: If the panels are shaded at anytime during the day by trees or buildings, their output will be reduced. As part of the design of the system we install at your facility, we will use a Solar Pathfinder to determine the amount of solar radiation and shade at the array site. The modeled output of the system will be adjusted downward to compensate for shade issues, so that the estimated production will already include a de-rating for shade. Season: The elevation of the path of the sun in the sky varies based upon the season; in summer it is at its highest
