Cost of solar panels over time graph 2018.

The dramatic drop in the cost of solar photovoltaic pv modules which has fallen by 99 percent over the last four decades is often touted as a major success story for renewable energy technology. In addition to solar panel efficiency increasing dramatically solar panel producers have significantly improved their manufacturing processes. How does system size impact the cost of solar. National data september 2020.

Over a decade ago in 2009 the cost of a solar panel installation was 8 50 per watt. The solar industry today looks very different. Cost of solar panels over time. Solar panel costs for an average sized installation in the u s.

Current industry average cost between 3 to 4 per watt average size solar panel system between 5 and 6 kilowatts a kilowatt is 1000 watts 3 26 per watt x 5 000 watts 16 300 per system before the 30 itc tax credit. 10 cost of solar panels cost of solar power charts. Ten years ago a residential photovoltaic system could cost more than 50 000 00. Usually range from 11 144 to 14 696 after solar tax credits and the average price per watt for solar panels ranges from 2 51 to 3 31.

When you look at more specialized panels that are manufactured in lower quantities the price climbs up above 2 watt. When adding in incentives like the federal tax credit the cost of utility scale solar drops further to just 32 per mwh. The cost of producing solar power is rapidly declining. Standard solar panels cost anywhere from 70 cents to 1 20 per watt depending on their output quality and where they are manufactured.

However solarreviews handles more than 1 000 quote requests per day and the current average price we see on our marketplace is 2 60 per watt. With higher efficiency government incentives and improved technology the prices of residential solar panels continued to plummet particularly over the past decade. It now costs 50 to produce one megawatt hour of solar power according to a new analysis.
