This article appears in the Spring 2020 issue of Energy Futures, the magazine of the MIT Energy Initiative. Benefits of solar photovoltaic energy generation outweigh the costs, according to new research from the MIT Energy Initiative.
By the 1990s, commercial panels reached efficiencies of 14-15%, making solar energy more viable for widespread use. The 21st century has seen exponential growth in solar panel efficiency. Current solar panel efficiency for commercially available models typically ranges from 15% to 22%.
Additionally, as demand for renewable energy sources rises, economies of scale will likely continue to reduce costs. The combination of these factors suggests that the cost of solar panels will continue to decline, making solar energy a more viable and attractive option for households and businesses.
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.
The price of solar panels over time Data from the National Renewable Energy Laboratory (NREL) documented that residential solar panel installations cost about $8.70 per watt in 2010, meaning the
