Evolution of solar PV module cost by data source, 1970-2020
Evolution of solar PV module cost by data source, 1970-2020 - Chart and data by the International Energy Agency.
Note: Costs are expressed in constant 2024 US$ per watt. Global estimates are used before 2010; European market benchmarks thereafter due to limited data availability. Solar photovoltaic module prices refer to the cost of the solar panel itself, and do not include installation or other system components.
Let's take a look at how solar panel cost and efficiency have changed over time. Solar panels are about 60% cheaper and 40% more efficient than they were in 2010. Solar panels in 2010 cost about $8.70 per watt and were about 15% efficient. Today, solar panels cost about $3.00 per watt on average and are between 19% and 22% efficient.
In 1950, photovoltaic power systems cost as much as $300. In 1970, when solar panels were not flourishing and the development of technology was not mature, not only the efficiency of solar panels is low, but also, the cost is high. Few people use, unless some special purposes, the price is even more prohibitive, about 100 dollars per watt.
The cost of solar PV modules has dropped by a massive 90% since 2000! The installed price of residential solar panel systems dropped by 26% over the last decade - from 5.7 $/W in 2013 to 4.2 $/W in 2022. Solar PV module prices dropped by 51% over the last decade - from 0.99 $/W in 2013 to 0.49 $/W in 2022.
