“…Results showed that the ETC field allowed the reduction in carbon dioxide emissions by 17.16 tons per year. The authors concluded that ETC systems can provide solar heat to industrial processes with temperatures between 80 and 120 • C. Barbosa et al [58] studied the economic and environmental performance of a water heating system with FPC for a textile industry located in northeast Brazil. Results showed that the system is economically and environmentally feasible, with an economic return 29.5 times greater than the capital invested.…”

“…The LCOE considers the costs related to the project such as initial investment, subsidies, or incentives, and operating and maintenance costs in the whole lifetime of the project. Other indicators also used to evaluate the economic performance of solar systems are the net present value (NPV) [22,58], internal rate of return (IRR) [22,58], payback period (PBP) [91,162], and life cycle cost (LCC) [89,92]. The NPV represents the present value of the difference between the revenues and costs in the lifetime of the project.…”

“…The NPV represents the present value of the difference between the revenues and costs in the lifetime of the project. This indicator allows investors to determine if the project will produce a positive cash flow balance that allows the recovery of the invested capital [58,162]. The IRR is the value of the discount rate that produces a NPV equal to zero.…”

Hybrid System of Photovoltaic and Solar Thermal Technologies for Industrial Process Heat

Process heating is the activity with the most energy consumption in the industrial sector. Solar heating (SH) systems are a promising alternative to provide renewable thermal energy to industrial processes. However, factors such as high investment costs and area limitations in industrial facilities hinder their utilization; therefore, hybrid systems that combine two different solar thermal or photovoltaic technologies where each technology operates under conditions that allow a higher overall performance than conventional configurations have been proposed. In this review, we discuss the limitations of conventional SH systems and the potential of hybrid configurations to overcome them. First, the current literature about conventional and hybrid systems is presented. Then, the application of common performance indicators to evaluate hybrid configurations is analyzed. Finally, the limitation, advantages, and potential applications of conventional and hybrid systems are discussed. This work shows that conventional systems are the most promising alternatives in low and high-temperature industrial applications. At the same time, in medium and processes, hybrid configurations have great potential to increase the performance of SH systems and help to boost their adoption in the industrial sector. There are few studies about hybrid systems in industrial applications, and further research is required to determine their potential.

“…An economic study has been performed to compare a SWHS, a "solar water heating system", to a natural gas boiler in terms of greenhouse gas (GHG) emissions and economics [117]. The SWHS economic assessment performed best.…”

“…Since the first year, the return rate was 25 times the minimum, and the net present value was positive. Payback took 5 months [117], and the profitability rate said the SHWS returned BRL 29.46 for every BRL 1.00 invested. The SWHS had higher equipment-related GHG emissions than the natural gas system, but its emissions (annual basis) were 50 times less due to the latter's heavy fossil fuel use [117].…”

Progress in Solar Thermal Systems and Their Role in Achieving the Sustainable Development Goals

The use of solar thermal systems (STSs) has recently reached a significant edge. The increasing research on developing an alternative power supply for limiting fossil fuel usage and climate change are the driving forces of STSs. The current work explores the recent progress in STSs’ applications, including PV/T or “photovoltaic/thermal” systems, zero-energy buildings, greenhouse solar thermal applications, solar thermal for pumping water, solar thermal refrigerators, solar chimneys, water desalination, and solar collectors, along with the benefits and challenges of these applications. Then, the potential contribution of STSs in achieving the various SDGs or “Sustainable development goals”, including barriers and research gaps, are elaborated. In brief, STSs significantly contribute to the seventeen SDGs’ achievement directly and indirectly. Recent developments in the engineering applications of STSs are strongly based on the materials of construction, as well as their design, process optimisation, and integration with multidisciplinary sciences and technologies such as modelling, nanoscience/nanotechnology, and artificial intelligence.
