Rapid growth in the solar industry made 2014 the best year yet!

It has been a great year for solar in the US! As the year comeRun on Sun crews to an end, we like to take a look at the numbers to get a sense of how the industry is doing as a whole. The first statistic I came upon stated that through just the first half of 2014, 53% of all new electric capacity installed came from solar!

According to the U.S. Energy Information Administration, utility-scale solar as of September, 2014 had sent 14.2 gigawatt-hours of electricity to the U.S. grid, up 110% compared to 6.7 GW in 2013. California is leading the way with a whopping 7.8 GW generated in 2014, 188 percent change from 2013!

That means solar generation was enough to meet the electricity needs of 1,513,703 average U.S. homes, and represented about 0.4 percent of the nation’s total electricity. However, these numbers don’t take into account residential and private commercial solar.

“There are now more than half a million homes and businesses nationwide with a solar installation,” reported the Solar Energy Industry Association (SEIA).

With continued growth and accounting for these additional sources of generation, solar electricity could easily account for 1 percent of U.S. generation by the end of this year. That might sound like small potatoes, but as recently as 2008 the energy contribution from solar was virtually zero. Rapid growth in the sector points toward continued gains in the near future.

What’s spurring this remarkable growth in the industry? For one thing, it is becoming more and more affordable with the average price of a solar panel declining by 64% since 2010. We also cannot overstate the role of effective public policies such as the solar Investment Tax Credit (ITC), Net Energy Metering (NEM) and Renewable Portfolio Standards (RPS) among other state and city-specific policies.

Growth in the solar sector has far reaching positive impacts for the US economy as well as the environment! While the numbers are not yet in for 2014, as of 2013 the industry had already provided 143,000 much needed jobs for Americans or more than 50 people hired in solar each day. Looked at another way, nearly $20 billion a year was invested back into the economy due to the industry.

On the environmental side Rhone Resch, CEO of SEIA, noted that solar will “help to offset an estimated 20 million metric tons of harmful CO2 emissions in 2014, which is the equivalent of taking 4 million cars off U.S. highways, saving 2.1 billion gallons of gasoline or shuttering half a dozen coal-fired power plants”. Needless to say, converting to solar or other renewable energy sources is paying huge dividends for both our economy and the environment. We look forward to sharing this great resource with continued growth in 2015 and beyond!

NPR gets the message - Solar is Now!

Readers of this blog know that solar is growing like crazy, and it looks like NPR has gotten the message. 
(H/T SolarWakeup.com)

Here is a Morning Edition story that you may have missed from last week amid the holiday hoopla:

Here are some key take aways:

  • Solar is growing fast - indeed, year-over-year growth of 30%+ is the hallmark of an exploding industry;
  • Costs are falling fast - with greater scale come the inevitable cost reductions making solar more affordable for more people;
  • Those falling costs don’t necessarily involve labor in China - LG modules that we use are made in South Korea;
  • Innovative financing is helping - true, but with a caveat. Residential leases are still a trap for people who aren’t good with math, but improved loan programs, the return of Home Equity Lines of Credit, and even HERO financing all have an important part to play.

Given that so many of our clients are NPR listeners, it is good to see that they are finally helping to spread the word that solar is here to stay!

Who's Fueling Whom? WSPA's Covert Campaign Against Cap and Trade

“Cap and Trade” - a sensible approach to addressing climate change by reducing emissions of Greenhouse Gasses - was once considered so non-controversial that even prominent Republicans like John McCain and even Newt Gingrich endorsed it.  Today the idea is routinely trashed in Washington as a “big government energy mandate“  that must be stopped at all costs.  And yet, in California, Cap and Trade has been up and running for nearly two years despite legal challenges and dire predictions that it would ruin the economy. (Hint: it hasn’t!)

Now the program (known as AB32) is set to expand to cover vehicle fuels, which account for one-third of all GHG emissions in the state, and industry, particularly the fossil-fuel industry, is attacking the program again.  Only this time they are playing a smarter, some would say more cynical, game - hiding behind “AstroTurf” groups to conceal their agenda. 

Perhaps you’ve seen this ad:

 WSPA astroturfing adHeavens, Californians are facing a “hidden” gas tax - oh no! - and who is giving you this news?  An attractive model fronting for something called the “California Drivers Alliance” who wants you to sign their petition.  In reality, what is hidden here is who is actually behind this ad - the Western States Petroleum Association (WSPA) and its fossil-fuel producing members.

In a PowerPoint presentation highlighting WSPA’s “Priority Issues” under the banner, “Energy Proud”, WSPA lays out how the current boost in domestic crude oil production should be “The Best of Times” except for those pesky concerns over the environment from fracking, oil spills, and yes, GHG emissions which threatens WSPA’s members with “The Worst of Times.”   Their response?  A massive astroturfing campaign designed to mislead consumers over the impact of this next phase of California’s cap and trade program all the while keeping the role of Big Oil out of the picture.

WSPA astroturfing

Fortunately WSPA has not been as sly as they intended, with their game plan having been made public, and now facing a coalition of pro-environment groups helping to unmask the powers behind the astroturfing. That coalition, operating under the name, Stop Fooling CA, is putting out the facts behind WSPA’s campaign to deceive the public, including clever graphics like the cartoon on the right.  On their website you can sign up for news alerts and add your name to the list of people who are pushing back against Big Oil’s covert attempt to derail the most successful cap and trade program anywhere in the world, and one that even the Wall Street Journal concedes, “may hold lessons for other states.”

BP Solar Flames Out - Leaves Consumers at Risk

Solar module manufacturer BP Solar - the “green” branch of energy giant British Petroleum (the same folks who brought you the Deepwater Horizon disaster in the Gulf of Mexico) - exited the solar market in 2011.  But now a class-action lawsuit is alleging that BP Solar knew as early as 2005 that some of its solar modules, including ones that were widely sold in California, pose a serious risk of failure and even fires.  Will BP step up and do the right thing?  (For the record, Run on Sun never used BP Solar modules.) 

BP does not deny that they have a potential problem.   In a carefully worded 2012 Product Advisory, BP acknowledged the following:

This product advisory is being issued to communicate a potential risk when using certain BP Solar modules in specific types of installations. Testing has shown there is a limited risk of cable to busbar disconnection in the junction box that, in rare cases, may lead to a thermal event in certain applications of the products referenced below. A thermal event, depending upon the severity, can cause secondary damage to surrounding materials that are not fire resistant.

While BP’s advisory uses the overly lawyered phrase, “thermal event” to describe what can happen, others use less measured language.  A report on Bay Area television station KTVU/Fox 2 speaks of consumer complaints about solar modules with a bevy of problems including “burning up, shattering and putting homes in danger.”

 

BP is not the only entity to “lawyer-up."  The two-person law firm of Birka-White is challenging BP in a class action lawsuit (see the complaint here) that harkens back to David taking on Goliath.  Birka-White, which had previously sued Suntech over problems with solar roofing tiles, a problem we have documented in this blog, alleges in their suit that a defect in the junction box on the affected BP solar modules causes them to fail, “resulting in a loss of electric current and serious safety risks, including the risk of fire."  Despite that risk, the complaint alleges that BP continued to sell the defective modules until 2010, even though BP knew of the defects “since at least 2005." 

More specifically, the complaint alleges that:

Burn damage to BP solar modules17. The connection between Solar Panels is made at a junction box attached to each Solar Panel.  A defect in the junction box and the solder joints between the connecting cables causes the solder joint to overheat.

18. When the solder joint overheats, the connection between the Solar Panels breaks. This break in the circuit results in an arc of an electrical current which generates heat between 2000-3000 degrees Fahrenheit.

19. The heat caused by this failure melts the junction box, burns the cables and the Solar Panel and shatters the glass cover of the Solar Panel. Attached hereto as Exhibit D are photographs of BP Solar Panel junction box failures. If there is flammable material near the heat source, such a [sic] dry leaves, the junction box failure creates a high risk of fire. Fires caused by junction box failures have already occurred and there is a substantial risk that they will occur in the future.

20. Because of the defect in the junction box, all Solar Panels relevant to this litigation have failed or will fail before the end of their expected useful life.

The photos above are taken from Exhibit D and show the sort of “thermal event” that the affected homeowners (the potential members of the class to be certified as part of the litigation) could experience.

Faced with such compelling evidence of product defects, what has BP’s response been?  You guessed it - to hide behind their limited warranty and to offer consumers a financial remedy that falls far short of making them whole.

To be sure, any product can have a defect, and it is by no means uncommon for a corporation to seek shelter from liability for such defects by pointing to limiting language in its product warranties.  Yet BP, which had a net profit in 2013 of $13.4 billion, would certainly seem to be in a position to compensate the innocent victims of its product defects more fully.  Of course, having halted solar operations altogether, BP has no ongoing vested interest in avoiding the black eye that its stonewalling will inevitably create for the entire solar industry.  Indeed, how will other solar module manufacturers respond to BP’s failure and the ensuing litigation?  Strong statements from industry leaders affirming their commitment to address promptly, and beyond the fine print of their limited warranties, problems arising from product defects could go a long way to restoring consumer confidence damaged by these BP revelations.

Scope of the Problem in California

We decided to take a look into the CSI data to get a sense of how big an issue this might be in California.  BP’s product advisory asserts that only certain module models, and only those manufactured from March 1, 2005 to October 31, 2006 have the defect that can lead to “thermal events.” The complaint, however, disputes that limitation, alleging that, “the risk of junction box failure exists for all Solar Panels - not just the limited number listed in the Product Advisory - manufactured at any time - not just the limited time frame covered by the Product Advisory.”

Regardless of which position is determined to be accurate, the CSI data provides no visibility into installations prior to 2007.  And while the problem may or may not affect module models beyond those listed in the Product Advisory, as far as the data is concerned, the vast number of residential installations made use of only two BP models: BP175B and BP4175B - both of which are listed on the Product Advisory.  Both products appear in the data as of 2007 (which could easily include modules manufactured during the Product Advisory period) and continue into this year.  The peak year for installations of the 175B module was 2010, whereas the 4175B peaked the year later, in 2011.  Here is the distribution:

BP module distribution

At a minimum, those 135 installation in 2007 would likely have used modules from the Product Advisory period, and if plaintiffs are correct, there could be as many as 1,300+ installations based on these two modules alone.

While there is no doubt that individual homeowners are at greatest risk, there are more than 100 companies that installed these BP modules, potentially exposing them to liability for failures.  Affected companies include major players like SolarCity, Verengo, and Sungevity, as well as dozens of much smaller companies, many of which are no longer in business.  Those companies relied upon BP’s representations and are also victims here.

While larger companies might have the resources (if not necessarily the inclination) to help out their customers in this situation, smaller companies with more limited resources are not in a position to foot the bill for replacement systems (the remedy being sought in the litigation).  Never-the-less, they can and should offer free inspections to their affected customers.  It will be far better for the solar industry if a customer learns of a potential problem from the company that installed their system than if they hear about it in the media, or worse, suffer a “thermal event” on their own roof.

As solar installers, we depend upon manufactures to produce products that are safe and reliable, and to stand behind those products when there is an issue.  We cannot, sadly, control the outcome when a supposedly competent manufacturer introduces defective products and then refuses to act responsibly.  We can, and must, however, take all reasonable steps available to us to mitigate the harm - to our clients and to the industry - when such unpleasant circumstances arise.
