Learn MorePhotovoltaic (PV) power generation is one main form of utilizing the solar energy and has developed very rapidly around the world in the past decade (Domínguez et al., 2015, Pinson et al., 2017, Zappa et al., 2019).
Solar PV is emerging as one of the most competitive sources of new power generation capacity after a decade of dramatic cost declines. A decline of 74% in total installed costs was observed between 2010 and 2018 (Figure 10).
Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.
The levelized cost of electricity for solar PV is already competitive now compared to all generation sources (including fossil fuels) and is expected to decline further in the coming decades, falling within the range of USD 0.02 and 0.08/kWh by 2030 and USD 0.014 0.05/kWh. Box 4.
Utility PV systems were benchmarked to have an LCOE of approximately 5 cents/kWh in 2020 (Feldman, Ramasamy et al. 2021). To achieve the 2030 SunShot goal, the lifetime economics of PV systems must be improved across multiple dimensions.
