In most rural areas, photovoltaic systems are often installed on the roof, but the rural construction environment is complex and diverse. Many systems are built, but photovoltaic power generation is not ideal, which makes users really anxious
so what's the problem
the power generation level of photovoltaic system mainly depends on two key equipment: photovoltaic module and photovoltaic inverter. Photovoltaic modules are most vulnerable to the surrounding environment. These impacts are mainly reflected in the surrounding trees and plants, buildings, dust, dirt, bird droppings, various antennas, as well as the common natural terrain in mountainous areas
next, let's talk about these occlusion sources
shelter source 1: trees and vegetation
for a long time now, when China's recycled plastic processing enterprises mainly evaluate self-employed businesses, some trees may not block the photovoltaic array, but after several years of growth, new branches and leaves may become the source of shielding. Speaking of the shelter of trees and vegetation, if it is the user's own, it's easy to say that as long as you trim it a little, you can remove the problem of shelter. But when the vegetation and trees are the neighbor's, the problem comes. If the relationship between the two countries is good, it can be solved by free operation training, free door-to-door delivery, etc. but if the relationship between the two countries is bad, the final solution is to move the photovoltaic system away
occlusion source 2: other buildings
other buildings here include neighboring assets or buildings located on the site, especially the newly built buildings are likely to become the areas suitable for the installation of photovoltaic systems at present
shielding source 3: building components installed with photovoltaic system
rural photovoltaic systems are built on roofs, which generally have chimneys, TV antennas and high-voltage lines. These should be told to the customer in advance before the design and installation
occlusion source 4: natural terrain
mountains and hills may become the shielding source of photovoltaic system, especially when the sun is low in the sky. Such problems have appeared in some poverty alleviation power stations in mountainous areas
source 5: dust, dirt, bird feces, fallen leaves, etc
the photovoltaic system is built outside and suffered from wind and rain. These acquired shielding sources, if not paid attention to, will also have a fatal impact on the photovoltaic system
recognize these shielding sources and understand the strong relationship between each other, so before the design, we should carry out on-site investigation, analyze the shielding sources, deal with the temporary shielding sources in advance, and do not build photovoltaic systems in areas with permanent shielding as much as 6.8% month on month. At the same time, regular on-site inspection should be carried out after the photovoltaic system is built, because the output power of photovoltaic modules will be significantly reduced after being blocked, and it is possible to damage the modules in the life cycle, and finally reduce the photovoltaic power generation and income. Therefore, the shielding source that appears the day after tomorrow should be removed in time. Only by doing well in these photovoltaic systems can the original intention of user construction be achieved - Section 3 about electricity charges and stable income
