The horizontally vs vertical placement component configuration mode and wiring will effect the cost of the system

With the advent of the era of parity on the Internet and low subsidy, the refinement of the system design requirements is higher and higher. Small solid found that for different components and inverter, optimizing the components and wiring can reduce the investment cost, improve system capacity.

through the area, the dosage of stents, wiring, installation difficulty level, system cost comparison to analyze the horizontally and landscape, the difference between single and multiple rows, let you find more suitable for his way of components!

component due to the arrangement before and after, there may be a certain area of the shadow of the shelter, the following figure, using once covered landscape arrangement of components, components of the output is small ( With reference to the structure of the components and the location of the bypass diode) 。

but if adopt the way of the horizontally, the component will be part of the output, the entire power components will be higher than the vertical placement ( Especially in the front row spacing design insufficient) 。

conclusion: according to the design principle of photovoltaic power station, photovoltaic array front row 9:00 to 15:00 PM components during the winter solstice is not cover, but in fact after 15 part still have considerable power. And some project array spacing, with the method of rank more conducive to reduce the power loss brought by block in the morning and evening.

we usually said, photovoltaic modules landscape arrangement, a rank of photovoltaic power station area. Here we through comparing 1 mw child square as an example.

conclusion: through digital point of view, can be found on the horizontally and landscape covers an area of poor value relative to the entire area is negligible, side-by-side in the actual project of optimized array, area and the landscape is not much difference.

the conclusion that can be found by comparing the horizontal steel weight of the double row than vertical double row arrangement is almost consistent ( The horizontally may be slightly more) Side-by-side, but compared with the basis of landscape costs ( Cement block) Relatively more.

photovoltaic modules can be used vertical double row, three or four row horizontal layout; And general installation components when fetching long side for installation, configuration, but when the rank is not convenient to grab long side, only by grasping the component installation workers to install the short edge; And horizontal row, middle, and the above components installed relatively more arduous.
