Photovoltaic panel module is a power generation device that will generate direct current when exposed to sunlight. It is composed of almost all solid photovoltaic cells made of semiconductor materials (such as silicon). Simple photovoltaic cells can provide energy for watches and computers. More complex photovoltaic systems can provide lighting for houses, traffic lights and monitoring systems, which are connected to the power grid. Photovoltaic panel modules can be made into different shapes, and the modules can be connected to generate more electric energy. Photovoltaic panel modules can be used on the roof and building surface, and even used as part of windows, skylights or shielding devices. These photovoltaic facilities are usually called photovoltaic systems attached to buildings.

The function of solar panel is to convert light energy into electric energy and input DC power into the battery. Solar panel is one of the important components of solar power generation system. Its conversion rate and service life are important factors to determine whether solar cells have service value.

At present, photovoltaic modules are gradually developing towards system installation, system power station and distributed application. Distributed is the development trend of solar power station in the future. This structure can easily install modules on the roof, which is convenient and fast, time-saving and labor-saving. It realizes the rapid installation of solar cell modules on the roof, which not only improves the installation efficiency of solar modules, but also saves space, At the same time, the support in this design can be folded and placed.

If your roof is completely flat, it is strongly recommended to install 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 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 fail and you will need to replace the module. The warranty condition for many panels is that they must be installed at least 10 ° from the horizontal, otherwise the warranty may be invalidated.

Don't listen to anyone 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 little self-cleaning ability in the rain, so you need to clean them manually more often.

Tilting the frame on a flat roof is a good idea. However, sometimes installers will propose inclined frames for roofs with small spacing to increase the angle of panels and obtain more energy. If you really want to lay these panels flat, there is an option: Frameless panel. These are panels without aluminum frames. This means that there are no ridges around the panel to collect dirt and water. However, the cost of frameless panel is high.

For these reasons, if you have a flat roof, most good installers will add the inclined frame option to their quotation.

Does the tilt angle really matter? Answer: Yes.

The tilt of solar panels will affect the power they produce, because the tilt will affect the sunlight you capture. Consider a flat solar panel on the ground, with a width of 1m. 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 optical axis: now, if the sun is at an angle of 30 ° to the horizontal, the same 1-meter-wide optical axis will actually expand more than 2 meters when hitting the ground: in this example, the flat solar panel will get only half the sunlight, Therefore, it produces half the energy compared with the sun directly overhead. Of course, the solution in this example is to tilt the panel 60 ° to capture all sunlight:

In the support of the solar equipment installation system on the plane roof, multiple groups of supports are arranged horizontally to jointly support the supporting parts. The spacing between the two adjacent groups of supports is not all equal, so that the support has better wind resistance. The distance from the lowest part of the solar panel to the flat roof shall be greater than 600mm. The combiner box and inverter are covered by the higher part when the solar panel is placed obliquely. The bottom plate at the bottom of the support rod is fixed with the base by U-bolts embedded in the base. The end of the support rod is provided with an elliptical hole for fine-tuning the height. The base is 500mm long, 500mm wide, 250mm high and weighs 150 ~ 160kg. The solar panel is rectangular, and the junction box on the back of the solar panel is located near one of the short sides of the rectangle. The placement mode of the solar panel is that the short side of the rectangle is parallel to the arrangement direction of multiple groups of supports, and the short side close to the junction box is higher than the other short side.

The solar energy equipment installation system on the flat roof comprises a base, a support fixed on the base and a plurality of solar panels arranged obliquely and evenly in a transverse direction. The support comprises a supporting member and a plurality of groups of supporting members connected with the supporting member. The supporting member supports the solar panel, and a plurality of groups of supporting members are arranged in a transverse direction to jointly support the supporting member of the residence, The spacing between two adjacent groups of supports is not all equal.
