If your roof is completely flat, it is strongly recommended to install the panels at an angle of at least 10°. This is very important because it allows rainwater to flow down the module. If rainwater accumulates on the surface of the solar cell panel, it is more likely to eventually pass through the seal of the panel and enter the solar cell itself. If this happens, the panel will malfunction and you will need to replace the module. The warranty condition of many panels is that they must be installed at least 10° from the horizontal, otherwise the warranty may be invalidated.
Don't listen to any saying that solar panels can be placed horizontally, just add one or two panels to make up for the loss of efficiency. Horizontal panels have almost no self-cleaning ability in the rain, so you need to manually clean them more frequently.
Tilting the frame on a flat roof is a good way. But sometimes the installer will propose a slanted frame for the roof that already has a small pitch to increase the angle of the panel and get more energy. If you really want to lay these panels flat, then there is an option: frameless panels. These are panels without aluminum frames. This means that there are no ridges around the panel to collect dirt and water. But the cost of Omega dimensions is higher.
For these reasons, if you have a flat roof solar panel mounting, most good installers will add a sloped frame option to their quotes.
The tilt of the solar panels will affect the power they produce, because the tilt will affect the sunlight you capture. Consider a solar panel that is flat on the ground, with a width of 1 meter. When the sun is in the middle of the sky (for example, at noon in summer), that solar panel will completely capture the 1-meter-wide solar axis: now, if the sun is at a 30° angle to the horizontal, then the same 1-meter-wide optical axis It will actually spread more than 2 meters when hitting the ground: in this example, a flat solar panel will only get half of the sunlight, and therefore generate half of the energy compared to the sun directly overhead. Of course, the solution in this example is to tilt the panel 60° in order to capture all the sunlight:
Flat roof mounting system for solar modules, wherein the opposite ends of the mounting system are bent downward to form a first leg and a second leg. The first leg and the second leg keep the photovoltaic module at a certain angle with respect to the flat roof, wherein the first leg The second leg and the second leg are screwed into the rafter, and the bottom ends of the first leg and the second leg are placed in the container, and the sealant is poured into the container to prevent water from leaking into the first leg by the fastener. Waterproof seal in the hole formed by the rafter of the building fixed to the second leg.
Sovereignty items An installation system for solar modules, including: (a) a mounting beam, including a first leg portion, a second leg portion, and a central portion extending between the first leg portion and the second leg portion , Wherein the second leg is longer than the first leg, so that the center portion is supported at a certain angle with the ground; (b) the first fastener located at the bottom of the first leg, the first fastener is configured to A foot is attached to the roof of the building; (c) a first container surrounding the bottom of the first fastener and the first foot; (d) a sealant arranged in the first container, wherein the sealant is The area where the first fastener is attached to the roof of the building provides a waterproof seal; (e) a second fastener located at the bottom of the second leg, the second fastener is configured to attach the second leg Connected to the roof of the building; (f) a second container surrounding the bottom of the second fastener and the second leg; and (g) a sealant arranged in the second container, wherein the sealant is in the second tight The area where the fastener is attached to the roof of the building provides a waterproof seal.
C- steel channel has the advantages of adjustable size and high compressive strength. Although the section size of the section steel formed by cold bending is light, it is very suitable for the stress characteristics of the roof purlin, so that the mechanical performance of the steel can be fully utilized. A variety of accessories can be connected into different combinations, with beautiful appearance. The use of profiled steel purlins can reduce the weight of building roofs and reduce the amount of steel used in engineering. Therefore, it is called economical and efficient steel. It is an alternative to traditional steel such as angle steel, channel steel and steel pipe. A new building material for purlins.
Galvanized C-shaped steel is widely used in purlins and wall beams of steel structure buildings, and can also be combined into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams and arms in mechanical light industry manufacturing.
Galvanized C-shaped steel, uniform zinc layer, smooth surface, strong adhesion, high dimensional accuracy, all surfaces are wrapped by zinc layer, surface zinc content is usually 120-275g/㎡, long service life, anti-corrosion and durable, it is a protection The strongest type of galvanized C-shaped steel is of high quality. Salient features
