The ground photovoltaic system refers to the photovoltaic system installed on the open ground outdoors. In general, due to factors such as geology, environment, and climate, the fixing methods of its brackets will also be different. Concrete strip (block) foundations are usually used, but pile foundations, ground anchors, etc. can also be used.

From the construction experience, the foundation of ground anchor construction is the strongest and safest. However, the connection between the ground anchor and the solar photovoltaic support needs to be specially customized, and the cost is relatively high. In comparison, the construction of the direct-buried foundation is simple. It is only necessary to use a drilling machine to drill holes on site and pour concrete. Before the concrete solidifies, the channel steel is directly inserted into the hole. However, compared with the ground anchor method, the direct-buried foundation has higher requirements on the self-sustainability of the soil on site and also requires preliminary geological survey experiments. Of course, if the geological conditions are good, the preliminary geological survey work can also be omitted.

The arrangement of the primary and secondary beams of the solar photovoltaic battery support is closely related to the placement of the battery panels. In general, the direct burial method is obviously better than the bolt method when the geological conditions permit.
