Price trends of photovoltaic panels over the years

KEY STATISTICS (EDITOR PICKS)The installed price of residential solar panel systems dropped by 26% over the last decade - from 5.7 $/W in 2013 to 4.2 $/W in 2022.Solar PV module prices dropped by 51% over the last decade - from 0.99 $/W in 2013 to 0.49 $/W in 2022.Since 2000 solar PV module prices have dropped by a massive 90%.

IRENA presents solar photovoltaic module prices for a number of different technologies. Here we use the average yearly price for technologies 'Thin film a-Si/u-Si or Global Price Index (from Q4 2013)'.

This report helps fill this need by providing a high-level overview of past, recent, and projected near-term PV pricing trends in the United States—focusing on the installed price of PV systems (i.e., the upfront cost borne by the system owner in terms of dollars per watt).

Solar photovoltaic costs have fallen by 90% in the last decade, onshore wind by 70%, and batteries by more than 90%. One of the most transformative changes in technology over the last few decades has been the massive drop in the cost of clean energy.

6 FAQs about [Price trends of photovoltaic panels over the years]

How have solar panels cost and efficiency changed over time?

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.

Are soft costs affecting solar installation costs?

As in previous years, soft costs remain a large and persistent portion of installation costs, for both solar and storage systems, and especially for commercial and residential systems. “A significant portion of the cost declines over the past decade can be attributed to an 85% cost decline in module price.

Will PV system price trends remain a downward trajectory?

As shown in Figure 13, most analysts also project that PV system price trends will maintain their downward trajectory in the near term. Owing to the global scope of most solar companies, analysts often project system prices across sectors and countries.

How efficient are rooftop solar panels?

The first ever functioning rooftop solar panels were installed atop a New York City rooftop in 1883 – and had an energy conversion rate of a mere 1%. By 2010, solar panels had efficiency ratings of around 15%. Nowadays, most monocrystalline solar panels have efficiency ratings between 19% and 22%.

Why are PV prices so high in California?

Because California accounts for such a large proportion of systems in the sample (as it does within the entire population of U.S. PV systems), the national trends for residential and commercial PV described below are dominated by trends within California, which has relatively high PV prices.11

What happened to solar energy prices in 2012?

Indeed, data published by the Solar Energy Industries Association (SEIA) and Greentech Media (GTM) for the U.S. PV market show that residential and commercial PV prices in the second quarter of 2012 fell by 12% and 11%, respectively, from the last quarter of 2011.14 Figure 3. Installed prices for the CSI program in 2011 and the first half of 2012
