Roof mounted PV plants in rural areas notice many different roof installation

Polaris solar PV net news: the mood “the appetite to the cloth”, for users who want to install photovoltaic power generation in rural areas, too. Roof construction of different users, the installation area of PV system design and installation is also different. Scientific design and installation it is essential, in fact, there is a trick to be found.

Rural roof has three main categories: color steel tile roof, brick roof, flat concrete roofs. There is a big difference in these three types of roof structure, even if it is the same size, amount of installed PV systems are not the same, for users how to estimate their roof can hold how much storage? Today we’ll talk about.

Look at the brick roof, this type of roof in the country built up, is the most common kind, first in building photovoltaic systems taking into account the occlusion, usually next to choose any 8 points to 4-5 in the morning, component lay on the South side, in theory, 1-kilowatt roof covers an area of about 10 square meters. Roof of the villagers in the countryside one side usually at 50 or so, meaning that you can install a 5kW solar system, measured according to average 4 hours of light, can power about 20 degrees a day, could produce 7300 a year.

Look at color steel tile roof of the structure, this type of roof folks lived not too much, because color steel tile roof cold in winter and hot in summer, the villagers do not look good. Many plants, livestock and other uses, and is South-facing installation when installing PV systems and components laying percentage and tile roofs similar to the 1-kilowatt area of about 10 square meters.

Third, flat concrete roof, commonly known as cottage in the countryside, is flat at the top, before installing a photovoltaic system has more demands on the design, first of all take into account the local light exposure, components receiving sunlight as much as possible, and secondly, we must take into account the components before and after shelter and parapet height of complicated factors. Want optimal radiation usually dip the PV array should be 0 ° to the local latitude. Array with angle, the area of the natural, plus also the component needs to have enough space to avoid shadows and the parapet wall mask. This flat roof-mounted photovoltaic system area will be larger than the roof of tile roofs. General 1-kilowatt system roof covers an area of 15~20 square meters, to install the 5-kilowatt project, for example, takes up 75~100 square meters.

Understand this, know your roof type, can be adapted to local conditions, find tips, if you want to install photovoltaic systems, you can estimate the volume of their roofs, of course this is only estimated, need a professional design company to do these things, after all, she is a professional.
