A solar tracker system is a revolutionary technology that automatically orients solar panels toward the sun throughout the day, maximizing energy production by 30-40% compared to fixed installations. The global shift to renewable energy has positioned solar photovoltaics (PV) as a leader in new power generation. The core challenge in solar energy is maximizing efficiency, which involves not only improving the solar cells themselves but also optimizing the amount of sunlight the panels receive. This adjustment minimizes light reflection, allowing the panels to capture more solar energy.
The organizational structure of this paper is as follows: Section 1 elaborates the background and research significance of rooftop PV; Section 2 constructs the economic index system to evaluate the rooftop PV; Section 3 analyzes the current status of China's rooftop PV industry; Section 4 analyzes the economic index value and the sensitivity of.
The results show that: For small rooftop photovoltaic in China, first of all, under the existing subsidy price and cost, its investment payback period is short and the risk is low. Secondly, the average internal rate of return is more than 10%, and the levelized cost of electricity is 0.2727–0.5573CNY/kWh, so the economic performance is good.
Furthermore, a system efficiency of 0.9 was considered satisfactory. This systematic technique guarantees a thorough examination of the capacity for generating solar energy from rooftop installations, enabling well-informed decision-making about efforts for energy sustainability.
By implementing rooftop solar PV systems, schools can significantly reduce their reliance on conventional energy sources, which are typically associated with higher costs and environmental degradation. This transition aligns with China's national renewable energy goals and carbon reduction targets, as outlined by the NDRC (2022).
As China's PV power generation technology has continued to advance and its application scale has gradually expanded, installed PV capacity has increased from 0.23 GW in 2010 to 252 GW in 2020, which shows that there is still much room for development of PV power generation in China.

Photovoltaic technology, often abbreviated as PV, represents a revolutionary method of harnessing solar energy and converting it into electricity. At its core, PV relies on the principle of the photovoltaic effect, where certain materials generate an electric current when exposed to sunlight.
PV technology development does not follow the well-know “generations” path. PV technology development is so far characterized by an evolutionary process. Wafer-silicon and thin-film technologies merge to yield the next step in PV. Photovoltaic solar energy (PV) is expected to play a key role in the future global sustainable energy system.
These aspects include the technological status, market status, economics, energy policies, and the future of PV. In addition, this entry presents a site-independent method for quantitative characterization and selection of PV technologies and modules.
An important strength of photovoltaic solar energy (PV) is that PV conversion can be realised with a multitude of materials and device designs and can be used for many different applications and markets.
To comprehend the intricate choreography of the photovoltaic effect, one must first grasp the fundamental concepts of solar radiation and semiconductor physics. Solar radiation, the radiant energy emitted by the sun, serves as the primary source of energy for PV systems.

To achieve carbon peaking and carbon neutrality in China, photovoltaic (PV) power generation has become increasingly important for promoting a low-carbon transition. The central and western desert areas of China have been identified as major areas for the construction of large PV bases.
PV power stations in the Northwest tend to be developed in the form of large-scale centralized PV parks. Land used for PV power stations were mainly converted from Gobi desert, sandy land, sparse and moderate grassland. The focus of China's PV industry is shifting from the northwest to the south and east.
Energy policies are the main factor driving the rapid development of PV power stations in China (Fig. 10 a) (Yang et al., 2020). Since 2004, China's PV production has experienced tremendous growth due to the dramatic increase in demand for PV in European countries and reached number one in the world in 2007 (Xu, 2016).
Firstly, the economic viability of solar PV stations in China at the provincial level is conducted via NPV and LCOE. Secondly, environmental performance is evaluated through the abatement of CO emissions. By introducing the shadow prices, the environmental performance is monetized.

With the help of a solar tracker! The solar tracking system adjusts the direction so that a solar panel is always positioned as per the position of the sun. Remarkably, by adjusting the panels perpendicular to the sun, more sunlight hits them. As less light is reflected in this way, the panels trap a greater amount of solar energy.
These efforts emphasize the significance of enhancing solar panel efficiency and energy production with sophisticated tracking and control systems. Recent developments in solar tracker systems include exploring different module geometries, materials, and tracking mechanisms to boost efficiency.
The solar tracking system plays an important role in different solar energy applications where its benefits not only exist in the power and efficiency gains and increase compared to the fixed systems, but also in the economic analyses of the large-scale solar energy applications.
It is an advanced sun monitoring system that can rotate the panels to track the movement of the sun across the sky. It facilitates the panel system to trap the maximum sunlight and optimise the energy output. There are considerable advantages to using a solar energy tracker.
