This paper reviews the status and prospects of global renewable energy deployments and their contribution to the total energy supply. Substantial renewable energy capacity expansion has occurred over the past decade due to decreasing costs and favorable policies. Globally, the power sector saw 256 GW of renewable power capacity added in 2020. The contribution of renewable energy to the other major end use sectors - transport and heating - is more modest. Major policy drivers for renewable energy deployments are coming from climate mitigation initiatives, including the 2015 Paris Climate agreement to limit global warming to no more than 1.5°C. To achieve this goal, GHG emissions need to be cut in half within the next decade, and to reach “net-zero”, by 2050. However, recent analyses show that current pledges by national governments are far less ambitious than need to be taken to remain within the 1.5°C limit. Several studies demonstrate how the 1.5°C limit can be achieved through large scale, and perhaps even 100%, renewable energy deployments. These studies conclude that a transformation to a fully decarbonized energy system, making extensive use of renewable technologies, is not only technically feasible based on current and emerging technologies but also results in a lower-cost energy system overall, creating significant market opportunities for renewables. For example, the solar PV market growth under these scenarios would be 10–15% annually over the next three decades–well within the growth levels the industry has experienced thus far.

本文综述了全球可再生能源部署的现状和前景，以及它们对总能源供应的贡献。在过去十年中，由于成本下降和优惠政策，可再生能源产能大幅扩张。2020年，全球电力行业新增可再生能源装机容量达256gw。可再生能源对其他主要最终用途部门- -运输和供暖- -的贡献则比较有限。可再生能源部署的主要政策驱动因素来自气候减缓举措，包括2015年巴黎气候协议，将全球变暖限制在不超过1.5°C。为了实现这一目标，温室气体排放量需要在未来十年内减少一半，到2050年达到“净零”。然而，最近的分析表明，各国政府目前的承诺远远低于保持在1.5°C限制内所需的雄心。几项研究表明，如何通过大规模甚至100%的可再生能源部署来实现1.5°C的限制。这些研究得出的结论是，广泛使用可再生能源技术，向完全脱碳的能源系统转型，不仅在现有和新兴技术的基础上在技术上是可行的，而且还会导致整体能源系统成本降低，为可再生能源创造巨大的市场机会。例如，在这些情况下，太阳能光伏市场在未来30年的年增长率将达到10-15%，远远超出了该行业迄今为止所经历的增长水平。

India has been one of the major deployers of solar PV during the last decade, having installed about 50 GW during this period. Since 2021, there has, in addition, been a great deal of interest to set up the solar manufacturing chain in the country, from polysilicon and wafers to cells and modules. Driven by a slew of policies and incentives announced by the government, several companies have announced and embarked on solar manufacturing. It is being estimated that by 2025, there will be about 40 GW of module production in India, some of it with full or partial upstream integration. This would make India one of the two or three leading solar manufacturers in the world. This paper describes the incentives provided and the companies’ responses to these incentives. It also describes and recommends technology options available for manufacturing in India, and estimates India's cost competitiveness of manufacturing, comparing countries as well as technologies. The paper further outlines the requirements for ancillary manufacturing units and for concerted R&D and training to support and enable a fully integrated modern solar manufacturing ecosystem in India. Although the focus of this paper is on India, the challenges and opportunities would also be relevant to other countries of the International Solar Alliance (ISA).

在过去十年中，印度一直是太阳能光伏发电的主要部署者之一，在此期间安装了约50吉瓦。此外，自2021年以来，人们对在该国建立太阳能制造链产生了极大的兴趣，从多晶硅和硅片到电池和组件。在政府宣布的一系列政策和激励措施的推动下，几家公司已经宣布并开始从事太阳能制造。据估计，到2025年，印度将有大约40吉瓦的组件生产，其中一些将完全或部分上游整合。这将使印度成为世界上领先的两三个太阳能制造商之一。本文描述了提供的激励和公司对这些激励的反应。它还描述并推荐了印度制造业可用的技术选择，并对印度制造业的成本竞争力进行了估计，比较了各国和技术。本文进一步概述了辅助制造单位和协调一致的研发和培训的要求，以支持和实现印度完全集成的现代太阳能制造生态系统。虽然本文的重点是印度，但挑战和机遇也与国际太阳能联盟(ISA)的其他国家相关。
