A Review Of Solar Energy

Solar Energy is the prime important source of energy, and it has continued to gain popularity globally. As of 2018, about 486 GW of solar PV was installed worldwide. One of the key requirements for socio-economic improvement in any nation of the world is the provision of dependable electricity supply systems. Recently, there is a massive growth in access to solar electricity in several Africa countries, notably South Africa, Egypt, Morocco, and Algeria. As a result, it decreases the global population without access to electricity with an appreciable value. This paper review the present state of solar energy capacity in the world also identifies vital approaches of improving their functionality, reliability, and affordability as well as the essential method that policymakers may implement in the future. The result shows that there is a recurrent growth in solar energy annually and as at the end of 2018 Asia with the largest capacity of 56.58%, while Central America and the Caribbean have the lowest installed capacity of 0.36%. As the request for an uninterrupted supply increases in different regions, progressive builders are embracing solar photovoltaics (PV) renewable energy as an option for their customers.太阳能是最为核心的能源来源，其在全球范围内的受认可度与应用规模持续提升。截至2018年，全球累计安装的太阳能光伏（Solar PV）装机容量约达486吉瓦（GW）。保障可靠的电力供应体系，是全球各国实现社会经济发展的核心前提之一。近年来，包括南非、埃及、摩洛哥、阿尔及利亚在内的多个非洲国家，在太阳能电力获取方面实现了大幅增长，由此显著减少了全球无电人口规模。本文综述了全球太阳能装机容量的当前发展态势，同时明确了提升其运行性能、可靠性与经济性的关键路径，以及政策制定者未来可采用的核心实施策略。研究结果显示，太阳能装机容量呈逐年稳步增长态势；截至2018年末，亚洲以56.58%的占比成为全球太阳能装机容量最高的地区，而中美洲及加勒比地区的装机占比最低，仅为0.36%。随着各地区对不间断电力供应的需求持续攀升，具备前瞻视野的开发商正将太阳能光伏（PV）可再生能源作为面向客户的备选方案。
