1. Background to the study
The research area is based on solar power technologies for the generation of sustainable
electricity. It presents the fact that most of the energy created globally makes use of fossil fuels
that involves the depletion of fossil fuel resources and the emission of environmentally
hazardous carbon dioxide. The study states according, to the US Department of Energy, the total
consumption of energy has been estimated to maximize by 44% by 2030 (Fuqiang et al., 2017).
On the other hand, as per the International Energy Agency, the share of fossil fuels in the
international energy mix is 82%.
The motivation of the research is that the study emphasizes different solar power technologies
that can be used for the generation of global sustainable electric power. It is important for the
industry as it fulfills the requirement of the industrial electrical generation. It is helpful for
industrial drying and analysis of industrial air-conditioning and refrigeration. On the other hand,
solar power technology also fulfills the energy demand of the industries.
2. The objective of the study
The two objectives of the study are as follows:
 To review and address the efficiencies and performance of solar power technologies
 To compare CSP and PV technologies for sustainability indicators
3. Literature Review
Energy is determined to be the most significant factor for economic prosperity and development
of any country. It is directly based on international key challenges that are faced by the entire
world such as, food security, global environmental change and poverty alleviation. According to,
Khan & Arsalan, (2016), the increasing energy crisis is considered to be one of the significant
problems of the 21st century. There is an increase in the energy demand at a rate proportional to
the economic and population growth of a country. Meanwhile, the utilization of fossil fuels is
estimated to be reduced by 75% by 2035 because of an understanding of renewable energy
sources. The development of a clean, endless and affordable innovation of solar power
technologies possess long-term benefits as it improves the power security of the countries. The
potential of solar energy is beneficial in various ways such as,

 Solar power systems are reasonable and relevant for both rural and urban areas
 Solar power is environmentally friendly, and it is socially accepted because of its efficient
performance and reliability
 The tropical and sub-tropical regions possess huge potential to harness the solar energy for
their electricity needs as these regions receive an increased amount of solar radiation
Comparison of PV and CSP technology
System efficiency
As compared to PV modules the CSP technology needs increased annual production of
electricity in terms of less output power. In the words of Prieto, Cooper, Fernández & Cabeza,
(2016), the solar PV installations have proved to be a more efficient system than CSP technology
because of its small land use needs. On the other hand, PV technology executes better
performance for both land use capability and electricity production. The annual production of
electricity is higher than PV technology where the conversion efficiencies of commercially
available PV systems are estimated to be 14-22%.
System sustainability
The significant relationship between sustainable development and global environmental
degradation is determined to be the major aspect. The carbon dioxide released from the burning
of fossil fuels is considered to be the largest source of greenhouse gas emissions (Stein & Buck,
2017). Moreover, the social acceptance, cost-effectiveness and environmental friendliness of the
implemented solar power technology are of great importance.
Environmental impacts
The long-term sustainability of solar power systems is determined by environmental impacts. As
per, Corona, Cerrajero, López & San Miguel, (2016), the significant issues of the solar power
plants are related to their decommissioning and assembling phase. At the time of the assembly
phase, the solar power systems create a higher influence on the environment than the CSP plants.
As per National Renewable Energy Laboratory, the harmonized median life cycle of greenhouse
gas emissions of the Trough and Tower based CSP systems differ from 22 to 23g CO2 eq/kWh.

Social acceptance
Social acceptance of solar power plants has received much more importance at an end-user level.
Relative growth of large-scale and small-scale solar power projects presents the acceptance of
solar power technology as a source of sustainable and clean energy. According to, Ahn et al.,
(2015), Spain and the United States have become the largest market CSP technology, while India
and China have become the largest share for PV technology related to solar power plants. As a
result, solar energy is being used by small-scale as well as large-scale applications.
4. Methodology
In order to review the solar power technologies for the generation of sustainable power, a
significant literature search has been conducted to recognize the existing appropriate studies. The
recognized studies have been evaluated based on diverse applications and different types of solar
power generation technologies. A review of both types of solar power technologies such as CSP
and PV has been performed, and their different types of concertation technologies have been
addressed. Based on sustainability indicators, the comparison between both CSP and PV
concentration technologies has been carried out (Kim & Kim, 2015). The recognized research
work has been demonstrated as per the review of the solar power technology and the
sustainability parameters. The study also provided an in-depth review of both CSP and PV
technology with their applications and types. Adoption of solar PV technology for off-grid and
grid-connected solar power studies has been highlighted.

The present study used both secondary and primary data sources where extensive fieldwork is
spanning for 36 months between 2012 and 2040 for evaluating the consumption of electricity.
The graph shows the percentage of electricity consumption from the year 2012 to 2040 by the
industries. The study interviewed 30 industry professionals that include solar PV scientists,
industry analysts, and employee of solar PV firms. The interviews were based on semi-structured
interviews related to the interview guide for an average of 1.5 hours (Vignarooban, Xu, Arvay,
Hsu & Kannan, 2015). On the other hand, the quantitative analysis included database
information on a total of 176 privately and publicly listed solar PV firms. The study collected
self-reported data based on the technology choices through personal communication, public
findings and company’s websites.
6. Findings
The graph represents the descriptive analysis of the variables used to review the consumption of
electricity by the industries that use solar power technologies. As a result, statistical inferences
could be drawn by comparing the ratio of the utilization of PV and CSP solar power
technologies. By separately modeling the choices of technology used by different industries it
can be seen that unexplained difference is the same across different types of industries (Li, Zhu,
Guo, Wang & Tao, 2017). The results demonstrated the fact that there is an increase in
technology with the number of cumulative production and forms.
7. Conclusion
The paper demonstrated that there is a continuous growth in the adaptability of PV and CSP
systems for greenhouse emissions. It evaluated the fact that currently, a large number of
sustainable energy solutions and customers uses conventional sources of energy. This particular
research work conducted different solar power technologies. It also discussed the environmental
impacts, economic issues and efficiency of the solar power technologies. However, the study
conducted literature search, review and comparison of different solar power technologies. The
data has been gathered through primary, secondary, quantitative analysis and semi-structured
interviews of the employees, consultants, and scientists who work for solar power technologies.
Therefore, the study helped in reviewing, addressing and comparing different solar power
technologies.
