The average price per watt dropped drastically for solar cells in the decades leading up to 2017. While in 1977 prices for crystalline silicon cells were about $77 per watt, average spot prices in August 2018 were as low as $0.13 per watt or nearly 600 times less than forty years ago. Prices for thin-film solar cells and for c-Si solar panels were around $.60 per watt. Module and cell prices declined even further after 2014 (see price quotes in table).
From 2016 to 2022, PV has seen an annual capacity and production growth rate of around 26%, doubling approximately every three years.
Though solar energy has found a dynamic and established role in today''s clean energy economy, there''s a long history behind photovoltaics (PV) that brought the concept of solar energy to
