The roof can be roughly divided into glazed roofs, concrete flat roofs, and color steel tile roofs. Waterproof is an important factor for the installation of rooftop solar mounting systems. The general principle of rooftop solar mounting structure design waterproof treatment is to ensure that the node treatment can smoothly let the water diarrhea go out when the rainstorm is accumulated and ensure that the roof is not leaked. 1. The waterproof of rooftop solar mounting structure on concrete flat rooftop For concrete flat roofs, ballast design is a good solution. The design does not need to be drilling holes on the roof. When installing, pay attention to the base of the bracket is not vertically arranged with the drainage direction, and does not hinder the rainwater discharge of the roof 2. The waterproof of rooftop solar mounting structure on color steel tile rooftop and glazed rooftop For the sloping roof of the upper tile, the punching depth should be confirmed. After the bolt is fixed, the bolt through the tiles should be used for good treatment. The bolt must be equipped with a weather -resistant waterproof pad, and after the bolt is fixed, the screw must be applied to the screw with high -quality neutral weather -resistant glue. For color steel, non -permeable standing seam and klip-lok clamp can be adopted. Corigy provides various non -permeable rooftop solar mounting structure design for different customer’s need.

Among the global wave of energy transformation, Europe is undoubtedly the most active market for renewable energy. Under the fossil energy supply crisis caused by the conflict between Russia and Ukraine, it has accelerated the energy transformation of European regions and continued to increase the demand for solar power system. According to PV Infolink's analysis of China's customs export data, a total of 49.0GW components were exported within four months in 2022, of which a photovoltaic component of 24.4GW was exported to Europe, accounting for 50%. It has grown 144%, the growth is quite significant, and the export volume of Europe has shown a monthly growth trend. It has not reduced due to the increase in the price increase of this year, showing that the region has a strong demand for solar energy system. Except that the German government announced that it would accelerate the deployment of renewable energy after the conflict between Russia and Ukraine, it is expected to reach 100%of renewable energy in 2035. At the same time, it is announced that 20GW is announced every year from 2028. The REPOWEREU PLAN announced by the EU Executive Committee will be installed in the EU countries in 2025 to reach 320GW. And in 2030, it will reach 600GW. At the same time, it is proposed that starting in 2026, the newly -built public and general buildings will gradually mandate the roof type photovoltaic. With the support of policy support, it has greatly stimulated the needs of the European market, and the European photovoltaic market will still be a region with a strong future growth.

The angle of which the solar panel mounting system are pitched is important. Not only does it affect the panel to get the highest efficiency, but also cause the power generation loss of the panel. Problems with flat installation The flat installation mentioned here does not necessarily mean that the installation surface has an absolute zero inclination. Usually, the installation with an inclination angle of less than 10 degrees is understood as a flat installation. Most of the photovoltaic modules installed flat have a problem, that is, the lower edge of the frame is easy to accumulate dust. And it cannot be discharged with rainwater, so it must be actively cleaned regularly. The fundamental reason for the accumulation of dust on the lower edge of the frame is that the inclination angle is too low, and the horizontal height of the frame has been higher than the glass at the cell, resulting in the inability of the muddy water to be effectively discharged. When the water evaporates, thick mud is left behind. This thick layer of mud will seriously affect the power generation of the blocked cells, and also affect the entire string of cells. The power generation loss of the modules will exceed 50%. Usually, when the inclination angle is greater than 10 degrees, it is steep enough to allow the muddy water to drain, at least not to block the glass on the surface of the cell. Therefore, most component manufacturers will recommend installation at an inclination angle greater than 10 degrees. However, the inclination of most color steel tile roofs is between 3-8 degrees. The brackets are generally installed parallel to the roof. If you want to avoid this problem, then the following design of Corigy is your best choose.

Solar power inverter can convert the variable DC voltage produced by solar panels to AC frequency of mains frequency. It can be fed back to the commercial transmission system or for use in off-grid grids. Solar power inverter is one of the important balance of system (BOS) in solar system, which can be used with general AC power supply equipment. Solar inverters have special functions for solar power system, such as maximum power point tracking and islanding protection. Where is the best place for home inverter to installed? 1. Installed on the mounting structure The installation scheme of common ground distributed projects can be installed under a certain string of components nearby. And the equipment can be directly fixed on the column using fixed bracket installation or hoop-type installation. This solution requires the strength of the bracket and the height of the solar power inverter from the ground, so as to prevent the equipment from being placed too low to flood in rainy days. 2. Installed on the roof For every 10℃ increase in ambient temperature, the life of electronic devices is halved. For this type of installation, if the inverter is exposed to the hot sun for a long time, the internal temperature of the inverter will increase greatly, which will seriously affect the life of the key components of the inverter. It is recommended to add a awning to the inverter to avoid direct sunlight. The vertical installation of the inverter on the flat roof will cause shadows, so when installing the equipment, try to install the components outside the shadow range of the inverter to avoid shadowing of the components. 3. Install on the wall The PV inverter must be placed in a well-ventilated space. The inverter is divided into two types: forced air cooling and natural heat dissipation. The inverter itself is a heat source, and all the heat must be dissipated in time and cannot be placed in a closed space, otherwise the temperature will rise higher and higher. There should have enough space to install and move the inverter. There should be at least a 50cm space above and below the inverter. The inverter that enters and exits the air from the left and right should be a space distance of more than 100cm on both sides. When installing, it should be at a suitable height from the ground so that the LED display can be observed and read.

Solar power system refers to the use of photoelectric properties of photovoltaic materials to convert the radiation energy of light into electrical energy (DC), and then merge it into the three-phase AC power grid through the inverter to generate new energy.  Different from the high power and wide area of large photovoltaic power stations, household solar power system refers to placing photovoltaic panels on the top floor of a family house or in a courtyard, using low power or micro-inverters for the commutation process, and directly using the energy. It can also integrate excess electric energy into the grid. 1. Loss reduction and cost reduction. Photovoltaic power is located on the user side, and the power generation is supplied to the load, which can effectively reduce the dependence on power grid power supply, reduce line loss, and save the user's electricity consumption. Surplus internet access and full internet access earnings can be obtained. 2. Low threshold. The construction threshold is low. Making full use of existing buildings or using photovoltaic cells as building materials can effectively reducing the floor space of photovoltaic power plants. 3. Independent operation. Effective interface with smart grid and micro grid can flexible operation. And can operate independently from the grid under appropriate conditions. 4. Green and environmental protection. The photovoltaic power station installed on the roof not only has the effect of heat insulation, cooling and beauty, but also can create green income.
