German PV = 50% of peak summer demand, US PV = 0.5%: chart

CleanTechnica

Yikes, that’s a bit of a humiliating stat, isn’t it? I’ve covered this sort of thing previously, when comparing solar power capacity of various countries to TWh of electricity production, to GDP, and per capita. At the end of 2011, Germany had over 39 times more solar power capacity per TWh of electricity production than the US, and it was second only to Italy. Relative to GDP, Germany had almost 24 times more solar power capacity than the US, and was second only to the Czech Republic. And per capita, Germany was #1 in the world, with about 21.6 times more solar power capacity per citizen than the US.

But, after seeing my Renewable Energy Big Pic: Part 2 post (Part 1 & Part 2 were full of graphs and charts), the good folks over at Energiewende Germany tweeted me this great chart (which seems to have been created by the German Energy Transition folks, using REN21 statistics):

germany-solar-PV-capacity-relative-to-electricity-demand-570x437

I’m  not going to lie, I love writing about the more or less exponential growth of solar power capacity in the US, but I’m also well aware of the fact that Germany is light years ahead of us in this arena. On the one hand, it’s a bit depressing. On the other hand, however, it’s inspiring and good proof that we could install a ton more solar power in the US without any major technical issues.

As pointed out several times now, solar power in Germany is much cheaper than solar power in the US, and studies have shown how that’s due to soft costs. The underlying problem is considered by some to be US solar incentives (good argument for that at that link) and just the fact that we have a much less mature market (as is obvious from the chart above).

How do we get to the level at which Germany now sits? I would probably agree with Jigar Shah that current US solar incentives are more of a hindrance than a help, and need to be cut. I would strongly support feed-in tariffs and PACE programs in more of the US. And I would simply say that solar companies need to invest more in creative, effective advertising that shows people it pays to go solar, it’s easy to go solar, and it feels good to go solar.

That’s my 2 cents. What do you think?

    So where is Australia by comparison? Total demand is approx 20GW and Roof-top PV alone makes up 2GW or 10%??

      Because rooftop solar is a bit higgley piggley with regards to orientation, a gigawatt of solar PV will produce about 800 megawatts at noon on a cloudless day and total electricity use is probably going to be higher than 20 gigawatts in the middle of the day. So at the moment solar might provide about 5% of electricity in the middle of the day. Of course it varies from place to place with South Australia getting a much larger portion of its electricity from solar than the Sunshine State Queensland. If it’s not hot, South Australia can get over 15% of its electricity from solar.

      But things are really just starting. As there’s no reason why we can’t get down to $2 an installed watt like Germany, it’s hard to say just when we’ll stop installing point of use solar.

Get up to 3 quotes from pre-vetted solar (and battery) installers.
