Solar power plant construction method

A solar power plant construction method of arranging a large number of solar strings in an array to form a large-scale power plant, the solar power plant construction method sequentially executing:

• a string formation step of delivering solar modules to a pre-assembly factory provided in a place different from a power plant site to arrange a predetermined number of unpacked solar modules on support frames to fix the solar modules as solar strings and applying cabling work in string for connecting the solar modules by electric cables in the solar strings to form planar solar strings;
• a string dedicated container conveyance step of stacking and housing a plurality of the solar strings in a string dedicated container and loading the string dedicated container on a container truck to convey the string dedicated container to the power plant site;
• a string dedicated container arrangement step of transferring the string dedicated container delivered to the power plant site to a site construction dedicated heavy machine and placing the site construction dedicated heavy machine at a predetermined position of a stand array group for mounting solar array provided in a field of the power plant site;
• a stand position measurement step of measuring distances and directions between a string dedicated crane included in the site construction dedicated heavy machine placed at the predetermined position of the stand array group and respective stands;
• and
• a solar string installation step of running the string dedicated crane of the site construction dedicated heavy machine to pull up the solar strings stacked and housed in the string dedicated container from above the string dedicated container to sequentially distribute the solar strings to respective stand positions measured in the stand position measurement step to form and fix a solar array and applying cabling in the solar array for applying wiring connection between the strings in the solar array and the cabling in site for applying the wiring connection in site.
