In some cases, the eaves load capacity is set for the above-mentioned frame considering the safety during snowfall.

When the eaves withstand load is revised to a larger value as described above, it cannot be said that all the existing solar cell power generation systems can satisfy the revised eaves withstand load. As a countermeasure in this case, first of all, snow removal is conceivable. Another possible measure is to reinforce the existing pedestal.

However, photovoltaic power generation systems may be installed in locations that are not always easily accessible, such as hilly areas. Therefore, snow removal can be difficult. Moreover, it cannot be said that snow removal is an essential measure for obtaining the desired eave load resistance.

On the other hand, even when reinforcing the mounting frame, if the installation location of the solar cell power generation system is a hilly area or a place with deep snow, it takes a lot of time and effort to transport and install the reinforcing members. . Moreover, since the height positions and inclination angles of the vertical beams and horizontal beams of the frame may change depending on the installation location, it may be necessary to select reinforcing members and adjust the sizes. Therefore, the reinforcement work is by no means easy.
