A solar power tower, also known as 'central tower' power plant or ' heliostat ' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target). Concentrated solar power (CSP), also called concentrating solar power or concentrated solar thermal, involves systems that collect solar. The Solar Power Tower is a large-scale solar thermal power system that uses mirrors to direct and concentrate sunlight into the tower-designed structure. The concentrated sunlight heats a working fluid such as molten salt or water to.

The major solar power technology currently available is the solar PV system, in which sunlight is directly converted into electricity via photovoltaic effect. The PV industry in China entered its period of rapid development during the 21st century because of the significant increase in global demand for PV products.
According to the national development strategy, China will develop solar photovoltaic power generation vigorously. Large-scale development of solar photovoltaic requires a lot of financial support, thus, how to achieve development goals with minimum cost is a meaningful study and can provide practical significance for policy studies.
However, our conclusions have policy implications for the large-scale consumption of PV power generation in China and other countries. In 2014, China's PV cumulative installed capacity reached 28.05 GW. Currently, supportive policies in China focus on the national level.
The market potential m of solar PV power in China reaches 1357 GW. This is higher than the results in the early studies, which predicted that the potential cumulative installed capacity of solar PV power will reach 287.68 GW in 2050.
The total potential for solar radiant energy is 1.7 × 1012 tons of standard coal equivalent per year for the country (Zhang et al., 2009a). China started generating solar photovoltaic (PV) power in the 1960s, and power generation is the dominant form of solar energy (Wang, 2010).
During the 1980s, China introduced several photovoltaic (PV) cell production lines from the United States, Canada, and other countries, which eventually formed the solar PV industry in China . By the end of the 1990s, a number of component packaging plants were built.

This study reviews research publications on rooftop photovoltaic systems from building to city scale.
Photovoltaic panel installations in roofs with different formats. PV modules can be placed horizontally or at an angle on flat roofs (Bayod-Rujula et al., 2011). In sloped roofs, PV modules are generally applied at the same inclination angle as the roof, and placed in parallel to increase the system efficiency.
The roof with a PV panel delivers 16% more energy than the system without tracking. The use of building-integrated photovoltaic (PV) systems in the form of retractable roofs is an alternative option to existing installations without tracking systems (NT) or horizontal single-axis tracking systems (HSAT).
The unique properties of roofs, such as good sunlight incidence, good ventilation conditions, no redundant shielding, and flexible tilt angle for PV panels, are advantageous for solar energy harvesting. Accordingly, roofs present the highest efficiency potential for PV generation systems in buildings (Lin et al., 2014).

Gernaat et al. (2020) estimated that the global suitable roof area for PV generation was 36 billion square meters. This represents a potential of 8.3 PWh/y, which is equivalent to 150% of the global residential electricity demand in 2015. This demonstrates the potential of replacing traditional electricity sources with rooftop PVs.
