Energy and Environment
Published in T.M. Aggarwal, Environmental Control in Thermal Power Plants, 2021
Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Commercial concentrated solar power plants were first developed in the 1980s. Photovoltaics convert light into electric current using the photoelectric effect. Photovoltaics are an important and relatively inexpensive source of electrical energy where grid power is inconvenient, unreasonably expensive to connect, or simply unavailable. However, as the cost of solar electricity is falling, solar power is also increasingly being used even in grid-connected situations as a way to feed low-carbon energy into the grid.
A Novel Internet of Things Access Architecture of Energy-Efficient Solar Battery Charging System for Mobile Phones
Published in Lavanya Sharma, Pradeep K Garg, From Visual Surveillance to Internet of Things, 2019
The advantage of the product is that it can charge mobile devices using solar power and WPT. There is no need to carry a charger device and mobile phone all the time. The work is based on natural energy, that is, solar energy by which the device gets charged. Solar power is a renewable energy source that has low maintenance costs with diverse applications. The solar power being used is captured in the monocrystalline solar cells that are most efficient in performance. WPT is combined with these cells to give the best charging experience while attaching the device to the back of the cell phone. This increases mobility while using mobile devices (cell phones). The proposed charging device is based on mutual inductance, magnetic resonance, and inductive coupling on different three-dimensional (3D) images, which are helpful to visualize the device.
Basics of Renewable Energy Systems Exergetics
Published in Evanthia A. Nanaki, George Xydis, Exergetic Aspects of Renewable Energy Systems, 2019
Solar energy is an available, cheap and environmentally friendly alternative source of energy, which can be integrated with different kinds of systems, in order to reduce energy consumption. Solar energy can be exploited via solar thermal technologies, which be used for water heating, space heating, space cooling, water treatment and process heat generation. In addition, solar energy can be used for the production of electric energy. Solar power converts sunlight into electricity, either directly using photovoltaics (PV), or indirectly using Concentrated Solar Power (CSP). CSP systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. PV converts light into electric current using the photoelectric effect.

One of the most promising energy sources for generating electricity in recent years is solar energy. Direct and indirect solar power are the two main categories, which the solar power system is typically divided. A solar photovoltaic system (PV), also referred to as a renewable energy system, is a direct solar power system made to harness solar energy and convert it into electricity using solar panels. This technological advancement offers clean, reliable, and emission- and pollution-free green energy. Grid-connected, hybrid, and off-grid solar photovoltaic systems are the three main categories of these installations. An indirect power system called concentrated solar energy is based on producing electricity using mirrors. Natural sunlight is reflected, focused, and concentrated on one area by the mirror, where it is then transformed into heat. The heat-transfer fluid is heated by the solar energy that has been captured and used. Following the creation of steam with the help of the heat energy, electricity is then produced. Later, when there is no sunlight, this energy may be used. Studies related to photovoltaic (PV) systems and concentrated solar energy (CSE) can be found in Refs. [1–4].

Due to the high electricity demand, industrial buildings cannot rely entirely on renewable energy. Therefore, buildings are connected to the national grid. Solar power can be used with a battery backup so that it is possible to obtain power even during nighttime. However, according to the expert interviews, using energy systems with a battery backup is expensive. Therefore, it is not popular among building owners to use a battery backup without a grid connection. Expert interviews suggested that biomass can be used as an on-site renewable energy source to generate electricity in industrial buildings. Similarly, many research studies also suggested biomass as a renewable energy generating sources (Abdelhamid and Bahmed 2011; Demirbas 2007; Fridleifsson 2001) Applicability of solar and biomass is discussed in detail in latter sections of this research study.
Optimisation and techno-economic assessment of parabolic trough collector system in Malaysia, China, and the United States

Solar energy is a renewable energy source, classified into solar photovoltaic (PV) and concentrated solar power (CSP) technologies. CSP technologies have the advantage over the solar PV system as they are always paired with a thermal energy storage system to store the energy to achieve continuous operation without sunlight (Liu et al. 2016). Among the CSP technologies, the parabolic trough collector (PTC) system has the highest technology mix or installed ratios in the world (>82%) among different types of CSP technologies due to longer commercial operational experience and fewer financial and technical risks (Achkari and El Fadar 2020; Xu et al. 2016).
