Are photovoltaics cheaper than conventional electricity?

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.

Why is solar photovoltaic technology so expensive?

Since the early 2000s, the total cost of solar photovoltaic (PV) technology has consistently sunk below expert expectations, mostly due to hardware improvements.

Can solar PV reduce LCOE?

Given the nationwide carbon emission trading scheme in China since 2017 , the carbon reduction of PV can be sold in the carbon trading market, thereby creating additional economic revenue. This revenue can offset part of the total costs and reduce the system LCOE, thus promoting the achievement of grid parity.

How has photovoltaic technology changed over the last decade?

Over the last decade, photovoltaic (PV) technologies have experienced tremendous growth globally. According to the International Renewable Energy Agency (IRENA), the installed capacity of PV increased by nearly a factor of 10, from 72.04 GW in 2011 to 707.4 GW in 2020 .

Are solar PVs cheaper than fossil fuels?

Over the past 40 years, solar photovoltaic (PV) prices have fallen by over two orders of magnitude, and during the period 2010 to 2021, the global weighted-average levelized cost of energy of newly commissioned utility-scale solar PVs fell by 88% (ref. 5), making solar PVs cheaper than fossil fuel power in some parts of the world.

Why are PV module prices falling?

Photovoltaic (PV) module prices are a key metric for PV project development and growth of the PV industry. The general trend of global PV module pricing has been a rapid and steep decline— an order of magnitude over the past 10 years (Mints April 2019)—enabled by economies of scale as well as manufacturing and technology improvements.
