Why the proportion of photovoltaic energy has increased significantly

Why the proportion of photovoltaic energy has increased significantly?

In recent years, the proportion of photovoltaic energy in total energy supply has increased significantly, mainly for the following reasons:

Technological progress and cost reduction: The efficiency of photovoltaic cells has continued to improve, from the initial 5-10% to more than 20% now. The manufacturing process and material costs have been greatly reduced, and the overall investment cost of photovoltaic systems has dropped by 60-70%. This makes photovoltaic power generation increasingly cost-competitive.

Increased policy support: Countries have introduced preferential policies, such as grid-connected electricity price subsidies and tax incentives to encourage photovoltaic power generation. Mandatory quotas for renewable energy and carbon emission restrictions have also promoted the rapid development of photovoltaic power generation.

In general, the rapid development of photovoltaic energy is the result of multiple factors such as technological progress, policy support, increased environmental awareness, and mature industrial chains. This trend is expected to continue in the future.

为何光伏能源的比例大幅度提升?

近年来，光伏能源占总能源供给的比例大幅提升，主要有以下几个原因：

技术进步和成本下降：光伏电池效率不断提高,从最初的5-10%提升到现在的20%以上。制造工艺和材料成本大幅降低,光伏系统的总体投资成本下降了60-70%。这使得光伏发电越来越具有成本竞争力。

政策支持力度加大：各国纷纷出台优惠政策,如上网电价补贴、税收优惠等鼓励光伏发电。对可再生能源的强制配额和碳排放限制,也促进了光伏发电的快速发展。

总的来说，光伏能源的快速发展是技术进步、政策支持、环境意识提升以及产业链成熟等多重因素共同作用的结果。这种趋势有望在未来继续保持。
