Solar power almost as affordable as fossil fuels, but still held back by red tape

Read this Aug. 19 story from The Atlantic on the staggering rise is affordability and availability of solar power – and how regulatory regulatory hurdles remain one of the final barriers holding it back from competing with fossil fuels.

The prices of solar cells are falling rapidly, and will keep doing so for the next few years. The big questions revolve around the rate of the price declines. And the panels themselves aren’t the only place where cost reductions will be found. America has very high “soft costs” — installation, permitting, marketing etc. Whittling down these expenses will help, too.

Solar is taking off at a breakneck pace (admittedly from a tiny base). Stephen Lacey at Greentech Media provides the striking figures illustrating the exponential growth of solar photovoltaics (PV) in the past few years:

It took nearly four decades to install 50 gigawatts of PV capacity worldwide. But in the last 2 ½ years, the industry jumped from 50 gigawatts of PV capacity to just over 100 gigawatts. At the same time, global module prices have fallen 62 percent since January 2011. Even more amazingly, the solar industry is on track to install another 100 gigawatts worldwide by 2015 — nearly doubling solar capacity in the next 2 1/2 years.

Even though prices of modules — the solar panel itself — have plummeted in the last few years, a report from the Department of Energy’s Lawrence Berkeley National Laboratory reveals that other costs haven’t been so easy to bring down:

Non-module costs — such as inverters, mounting hardware, and the various non-hardware or “soft” costs — have also fallen over the long-term but have remained relatively flat in recent years. As a result, they now represent a sizable fraction of the total installed price of PV systems.

So, Greentech Media analyst Shyam Mehta cautions that panels getting cheaper actually might not bring down total prices by much:

[There is] the issue of exactly how meaningful a reduction of around $0.20 per watt in module prices (from $0.62 per watt at the end of 2012 to $0.42 per watt in 2017) is in the overall context of [solar] economics. Assuming an installed cost of $2.25 per watt for a utility-scale system in the U.S. right now, our base-case forecast implies a system cost reduction of less than 10 percent…It’s not exactly a game-changer.

David Roberts at Grist suggests that reducing the soft costs that are staying stubbornly high in the U.S. will be a key part of driving solar forward:

When it comes to accelerating the wide deployment and falling costs of clean energy, market innovation is every bit as important as technological innovation. Even if PV technology remains static (which of course won’t happen), enormous savings could be had simply through market building — helping markets with high soft costs match the performance of those with low soft costs.

Much of the soft costs holding back solar are related to regulation. In the New York Times, David Crane and Robert F. Kennedy criticize the amount of red tape in the U.S. and advise America to learn something from Germany’s solar success:

In Germany, where sensible federal rules have fast-tracked and streamlined the permit process, the costs are considerably lower. It can take as little as eight days to license and install a solar system on a house in Germany. In the United States, depending on your state, the average ranges from 120 to 180 days.
