There is no shelter on the back. The double-sided+intelligent tracking mode greatly improves the power generation. It can track the sunlight in real time and search for light intelligently.
Obviously, dual-axis tracker systems show the best results. In [2], solar resources were analysed for all types of tracking systems at 39 sites in the northern hemisphere covering

The estimation of PV power potential is obtained from the effective PV area, solar radiation, and conversion efficiency of PV panels [27]: (10) E = I × e × A PV × λ where E
In order to get the maximum power output of the whole photovoltaic power generation system, we usually need to fix and place the solar panels with a certain orientation through the solar photovoltaic bracket.

In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed.
A ground-mounted photovoltaic power plant comprises a large number of components such as: photovoltaic modules, mounting systems, inverters, power transformer. Therefore its optimization may have different approaches. In this paper, the mounting system with a fixed tilt angle has been studied.
The most used rack configurations in photovoltaic plants are the 2 V × 12 configuration (2 vertically modules in each row and 12 modules per row) and the 3 V × 8 configuration (3 vertically consecutive modules in each row and 8 modules per row). Codes and standards have been used for the structural analysis of these rack configurations.
The described methodology has been applied in Sigena I photovoltaic plant with a fixed tilt angle, 2 V × 12 configuration with a tilt angle of 30 (°), located in Northeast of Spain (Villanueva de Sigena). From a quantitative point of view, the following conclusions have been reached:
Safety Analysis under Extreme Operating Conditions For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length . To ensure the safety of PV modules under extreme static conditions, a detailed analysis of a series of extreme scenarios will be conducted.
The first type, ground-mounted photovoltaic, has a fixed tilt angle for a fixed period of time. The second type uses a solar tracker system that follows Sun direction so that the maximum power is obtained. The solar tracking can be implemented with two axes of rotation (dual-axis trackers) or with a single axis of rotation (single-axis trackers).
