Technical FAQs 4

Are solar PV projects reducing the cost of electricity in 2022?

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.

How has solar impacted global power generation?

Regarding global power generation, solar nearly doubled its share over the past 3 years, growing by 1.3 percentage points only last year to a 7% share in the world’s electricity mix. This growth continued to drive renewable penetration and pushed additions of conventional electricity sources to a new low.

Why are solar products so affordable?

Technology improvements that have turned versatile solar into the lowest-cost power generation technology in many places around the world, along with record-low solar component prices – largely due to significant manufacturing overcapacity along the solar value chain – have made solar products more affordable than ever.

Where did photovoltaic cost data come from?

Photovoltaic cost data between 1975 and 2003 has been taken from Nemet (2009), between 2004 and 2009 from Farmer & Lafond (2016), and since 2010 from IRENA. Prices from Nemet (2009) and Farmer & Lafond (2016) have been converted to 2024 US$ using the US GDP deflator, to account for the effects of inflation.
