The photovoltaic carport is mainly composed of a bracket system, a battery module array, a lighting and control inverter system, a charging device system, and a lightning protection and grounding system. The bracket system mainly includes supporting columns, inclined beams fixed between supporting columns, purlins connected to the inclined beams for supporting the solar cell module array, and fasteners for fixing the battery module array.
Before installing the solar photovoltaic carport, it is necessary to do a good job of on-site survey and design
1. Dimensional survey of the parking lot.
2. Determine the type of parking: such as cars, buses, trucks, battery cars, etc., what kind of vehicles will need to be parked in the future, and regional planning.
3. Plan parking spaces.
4. Measure and mark the height and orientation of trees, houses, etc. around the parking lot.
5. According to the on-site conditions, select suitable solar photovoltaic panels (conventional components, double-glass components, thin-film components, size, power).
6. Functional requirements of the parking shed, waterproof carport or ordinary carport.
7. Determine the system type, off-grid system or grid-connected system, or off-grid system or grid-connected energy storage system
8. The installation location of the inverter (battery).
After the above data is confirmed, a planning and design should be made.
According to the project site survey and the needs of the owner, the photovoltaic carport should be designed systematically and structurally. 1. Orientation: Although it is ideal for photovoltaic power generation to install the components with the tilt angle facing due south, it is also possible to choose east, west, or due east or due west, taking into account the considerations of parking and the shadows of surrounding obstacles.
2. Angle: The tilt angle of the components has an optimal tilt angle in each region, but for photovoltaic carports, considering the structural strength and cost of the carport, we generally recommend that an tilt angle of 5-10 degrees is ideal, and those greater than 15 degrees should be carefully considered.
3. Parking space: The width of a single parking space for a car is between 2.5 meters and 3 meters (the span of a two-space carport is between 5 and 5.8 meters)
4. Waterproofing: There are three common waterproofing methods for waterproof photovoltaic carports:
(1) Fill the gap between components with rubber strips and seal with waterproof glue.
(2) Glue the gap between components with waterproof tape.
(3) Use waterproof structure to make components. The waterproof structure uses aluminum alloy guide grooves to fix the components and allow rainwater flowing from the gap between components to flow away through the guide grooves, thereby playing a waterproof role. This waterproof structure designed and developed by Mesler can be used in photovoltaic carports, sun sheds and factory roofs. After years of project practice, it is safe and reliable, and can be easily maintained in the future.
5. Components: Try to choose conventional framed components, especially when making waterproof photovoltaic carports, framed components are more convenient to use.
6. Modeling: Generally divided into single-side parking and double-side parking carports, single-column carports, etc. For details, please refer to the selection instructions of the Meisaler photovoltaic carport, and other photovoltaic carports can be customized for customers.
7. Material: Because the service life of photovoltaic carports is more than 25 years, the current mainstream carport materials are generally aluminum alloy or carbon steel hot-dip galvanized. The surface of the aluminum alloy carport is anodized, which is beautiful and generous; the surface of the carbon steel material is hot-dip galvanized, which is durable.
8. Geographical location of the project site: used to understand the local climate conditions as a reference standard and basis for the structural design of the photovoltaic carport. (Local snow thickness and maximum wind speed)
The installation foundation of the photovoltaic carport is the key, and the local wind speed and snow accumulation must be fully considered.
