Price of photovoltaic panels and electricity generation

The costs of solar PV projects include power generation, predevelopment, construction, and operation and maintenance costs, as well as the discount rate of fixed-term considerations, the depreciation of fixed assets, and/or the residual value of assets (equation (1) 63):

Meanwhile, the costs of manufacturing PV panels have dropped dramatically, with the cost of the commercial PV modules declining from 1.7 USD/W in 2011 to 0.2 USD/W in 2020 . In some countries, PV have even become the cheapest option for new electricity production plants .

The price of photovoltaics (PV) has been steadily decreasing over the last decade, and many reports suggest that PV has become considerably cheaper than conventional electricity sources. In this paper, we critically evaluate the PV grid parity and use China as a case study.

Although solar photovoltaic use grows rapidly in China, comparison with grid prices is difficult as photovoltaic electricity prices depend on local factors. Using prefecture-level data, Yan et al. find that 100% of user-side systems can achieve grid parity, while 22% can produce electricity cheaper than coal-based power plants.

Additionally, the cost of solar PV power generation was CNY5.6–15.1 kWh −1 in 2000, which fell to CNY0.29–0.79 kWh −1 in 2018, with an average annual decrease of CNY0.28–0.75 kWh −1 (Fig. 1). Technological progress sheds light on less expensive and more commercially viable solar systems, and increases the competitiveness of the solar PV market.
