The cost of solar in 2020 is about 12 920 after tax credits 2 91 watt the cost of solar has fallen over 20 over the past 5 years.

The most recent official data from the doe funded lawrence berkeley labs published in september 2019 found that the median cost of residential solar panels is 3 70 watt. Ten years ago a residential photovoltaic system could cost more than 50 000 00.

Back in 1977 the price of solar photovoltaic cells was 77 for just one watt of power. Bell labs invented the first useful solar cell more than 60 years ago and scientists have known for centuries that the sun can be used to produce energy. Cost of solar panels over time the average cost of solar panels has fallen 65 from 7 34 per watt in 2010 to 2 53 per watt in 2019. The cost of solar panels over time the cost of solar panels has declined substantially over the last decade as the industry has matured and reached production at the largest global scale.

Since 2010 solar panel prices have fallen by roughly 90 while global solar deployment has grown by over 400 and this incredible growth rate along the entire global solar supply chain has dramatically reduced prices.
