About The cost of solar photovoltaic power generation
The cost of solar photovoltaic power generation has been declining steadily due to the widespread availability of materials, which reduced production expenses12. In 2021, the average installed cost of solar PV systems stood at 857 U.S. dollars per kilowatt1. The cost decline can be attributed to an 85% cost decline in module price2. The global weighted average levelised cost of electricity (LCOE) of new utility-scale solar PV fell by 13% year-on-year to USD 0.048/kWh in 20213. The Solar Energy Technologies Office (SETO) is working toward a levelized cost of $0.02 per kilowatt-hour (kWh) for utility-scale solar photovoltaics4. On average, solar panels cost $8.77 per square foot of living space, after factoring in the 30% tax credit5.
Between 2010 and 2021, the average installed cost of photovoltaics worldwide declined steadily due to the widespread availability of materials, which reduced production expenses. In 2021, the average installed cost.
“A significant portion of the cost declines over the past decade can be attributed to an 85% cost decline in module price. A decade ago, the module alone cost around $2.50 per watt, and now an entire utility-scale.
The global weighted average levelised cost of electricity (LCOE) of new onshore wind projects added in 2021 fell by 15%, year‑on‑year, to USD 0.033/kWh, while that of new utility-scale solar PV fell by 13%.
SETO is working toward a levelized cost of $0.02 per kilowatt-hour (kWh) for utility-scale solar photovoltaics, $0.04 per kWh for commercial PV systems, and $0.05 per kWh for residential rooftop PV systems.
On average, solar panels cost $8.77 per square foot of living space, after factoring in the 30% tax credit.

6 FAQs about [The cost of solar photovoltaic power generation]
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.
Are solar PV prices going down?
Nonetheless, rapid price declines in solar PV have not been without controversy. China, for example, has played an outsized role in scaling up the mass production of solar PV cells and modules, comprising 78% of global production in 2021 9, 10 (Fig. 1).
How much did solar PV invest in 2022?
Global solar PV investments in capacity additions increased by over 20% in 2022 and surpassed USD 320 billion, marking another record year. Solar PV comprised almost 45% of total global electricity generation investment in 2022, triple the spending on all fossil fuel technologies collectively.
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.
Do solar photovoltaic energy benefits outweigh the costs?
This article appears in the Spring 2020 issue of Energy Futures, the magazine of the MIT Energy Initiative. Benefits of solar photovoltaic energy generation outweigh the costs, according to new research from the MIT Energy Initiative.
How do we estimate learning rates for solar PV modules?
Using nation-specific, component-level price data and global PV installation and silicon price data, we estimate learning rates for solar PV modules in the three largest solar-deploying countries (China, Germany and the United States) between 2006 and 2020 using a two-factor learning model.
