Swanson's law–stating that solar module prices have dropped about 20% for each doubling of installed capacity—defines the "learning rate" of solar photovoltaics. [1] [2] Swanson's law is the observation that the price of solar photovoltaic modules tends to drop 20 percent for every doubling of cumulative shipped volume. At present rates ...
Prices for thin-film solar cells and for c-Si solar panels were around $.60 per watt. [43] Module and cell prices declined even further after 2014 (see price quotes in table). This price trend was seen as evidence supporting Swanson's law (an observation similar to the famous Moore's Law) that states that the per-watt cost of solar cells and ...
Solar panel performance is usually guaranteed for 25 years and sometimes 30. [62] According to a 2021 Harvard Business Review study costs of recycling solar panels will reach $20–30 per panel in 2035, which would increase the LCOE fourfold for PV solar power but only if panels are replaced after 15 years rather than the expected 30 years.
The average retail price of solar cells as monitored by the Solarbuzz group fell from $3.50/watt to $2.43/watt over the course of 2011. [86] In 2013 wholesale prices had fallen to $0.74/W. [ 85 ] This has been cited as evidence supporting ' Swanson's law ', an observation similar to the famous Moore's Law , which claims that solar cell prices ...

After years of cost reduction, the average US price per watt was between $2.51 to $3.31 in 2020 for 10 kW systems, [89] and $1.05/W for utility systems.
