Solar Power Projects Racking design considerations

摘要

NEARLY EVERY SOLAR ENERGY PROJECT requires some sort of racking solution to mount the solar panels. From roof- and ground-mount projects (including fixed or tracker applications), to carports and covered parking or specialty structures, there are some basic racking design considerations that apply to every solar project. Once a location has been selected for a solar power project, additional decisions should be made on the following important features... Shading considerations. Solar modules need the sun to do their job, so it's important to take account of any surrounding obstructions that might shade or interfere with the efficiency of energy production. Azimuth and tilt. Installations should be oriented in such a way as to optimize production - in the United States, solar modules are generally pointed south; the tilt will vary based on the project location's latitude or other production analysis. Racking type. Whether roof-mount or ground-mount, fixed-tilt or a tracking system, any one or a combination of racking solutions are available and must be considered depending on the project.
