13 Charts On Solar Panel Cost & Growth Trends
September 4th, 2014 by Zachary Shahan
The following charts on solar panel cost trends and solar power growth trends are fun, and good for a share, since many people are completely unaware of these trends.
Of course, to get a very specific cost of solar panels estimate for your own home, you can just spend about 60 seconds answering a few question at the link above and we can hook you up with this in a jiffy. (A completely free process, of course.)
But, if you’re just interested in some general information on solar panel cost and growth trends, look no further — we’ve got the goods right here:
13 Cost of Solar Panels & Cost of Solar Power Charts &Graphs
1. The average cost of solar cells has gone from $76.67/watt in 1977 to just $0.74/watt in 2013. [Update: PVinsights shows the average price of a solar module at $0.49/watt on July 15, 2016, and the average price of a solar cell at $0.26/watt.]
Well, that basically tells you everything you need to know right there — the cost of solar panels in 2013 was about 100 times lower than the cost of solar panels in 1977 (even more than 100 times lower!) — but I promised 10 charts, so let’s dig in even further and throw on some other fun charts and graphs.
2. What is really important is that the cost of electricity from solar panels is now lower than the cost of retail electricity for most people.
That’s big! That means that people like you and me (if we have a roof) can cut our electricity costs by putting solar panels on our roofs! This is why major companies like Walmart, IKEA, Google, Apple, Facebook, Costco, Kohl’s, Macy’s, Staples, and many others are starting to go solar in a big way.
Of course, as you can see in that graph above, the cost of solar is headed towards the wholesale cost of electricity from natural gas… which would actually get utility companies and power plant developers switching to solar in a big way. (The cost of solar power actually varies quite a bit from place to place, and solar has crossed those lines in some locations.)
3. Here’s another look at the falling cost of solar panels (or, as the industry often calls them, solar modules), focusing on the years 1985–2011 (the price has continue to follow the trend through today):
4. Are you actually interested in the cost of installed solar power systems? And even perhaps the cost of installed solar power systems by sector? Here’s a chart on that, for the US [update: I’ve replaced a Q1 2014 chart with one from Q1 2016]:
5. Are you interested in seeing how the cost of solar panels compares to the cost of its main competitor? If so, have a look at this comparison between the cost of solar and the cost of electricity from gas- and diesel-fired peaking power plants [a newer chart from the same source replaced the original chart on July 15, 2016]:
6–10. Are you interested in seeing how much solar panels save the average American who goes solar … or the average person in sunny states like California, Florida, New York, Texas, Hawaii, and so on? Below are two infographics on just that. Just note, however, that these averages are based on the cost of solar panels in 2011 (as I think you’ve gathered by now, the cost has dropped considerably since then).
10–12. So, with all of this information on the drop in the cost of solar panels and the cost of solar-generated electricity, you’re probably thinking that solar power project growth should be going through the roof by now, right? Indeed, it is [charts were updated on July 15, 2016, to be much more up to date]:
13. And perhaps my favorite solar power graph, this one is titled “Welcome to the terrordome!”
So, what’s the lesson today?
The lesson is: the cost of solar panels has fallen off a cliff, and that means that solar power now crushes electricity from the grid for a huge number of people. If you have a roof and don’t have solar panels on it, stop wasting your time and see what the cost of solar is and how much you can save right now!
