There are three main types of roofs in rural areas: color steel tile roofs, brick and tile structure roofs, and flat concrete roofs. There are great differences in these three types of roof structures. Even with the same area, the way to install photovoltaic power generation systems is also different. Today we will talk about the issues that should be paid attention to when installing photovoltaic power stations on color steel roofs:
1. Investigate the site selection of the roof photovoltaic array: (1) Roof structure (fixed brackets to ensure waterproof). (2) Purlin spacing, direction, dimension distance. (3) Roof structure and component arrangement. (4) Avoid shadow occlusion.
2. Do a good job of waterproofing: When installing a photovoltaic system, first of all, ensure that it is installed under the condition of avoiding damage to the roof. The roof with a waterproof layer needs to avoid punching holes, and the color steel roof needs to use waterproof glue or rubber pads for punching holes.
3. Placement of length and width of components: During installation, the length and width of the components are determined according to the roof area. When the long side of the components is perpendicular to the keel, the cost of the bracket is saved. When installing, reserve the width of the wiring trough.
4. Colored steel roof load: In general, the installation of photovoltaic power generation equipment on the steel structure workshop will increase the weight by 15 kg per square meter. The roofs of large commercial enterprises generally have the drawings of the original design institute. If we can obtain the drawings before the inspection, we can Learn more about roof structure and electrical structure distribution. Check whether the roof load meets the installation requirements through the drawings, check the design value of the dead load in the architectural design description, and determine whether other loads are added in addition to the roof's own weight, such as pipes, hanging equipment, roof attachments, etc., and determine the dead load Whether there is a margin to install photovoltaic power plants.
