12 Solar Power Myths and the Saving Grace of a Worthwhile Cause

Paula Mints SPV Market Research/Strategies Unlimited

 4.     PV cell and module prices are not too low

The viewpoint that PV cell and module prices are not too low and that these low prices represent progress comes from the demand side of the PV industry.  On one hand, these prices are responsible for increased interest in solar. On the other hand, these low prices are responsible for manufacturer failures and low investment in R&D. 

5.     PV cell and module prices will never increase

Referring back to Figure 1, it is an old market research pricing adage, what goes up will come down and then back up, though not as high as before. Price behavior is a roller coaster with many ups, downs and swift, nerve wracking changes in direction. Today’s prices for PV technology are unlikely to go up until the inventory is worked off and the consolidation is complete. At that point, depending on the available incentives and demand, prices will stall and may well tick up for a while.  Over time prices for PV technology have decreased by a compound average rate of 6% a year.  Individual years have seen significant upswings and significant decreases depending on the market environment.

 6.     An industry-changing new PV technology is just around the corner

 Over its ~40 year history as a terrestrial technology, the PV industry has continued to improve its manufacturing costs while increasing conversion efficiency – these improvements and innovations are incremental and the result of long years of R&D and pilot scale manufacturing.  PV technology is a high quality, reliable, long lived energy technology that converts the freely available fuel from the sun to usable clean electricity.  The potential applications for this innovative technology and its incremental advances are too many to name.  In developing this technology the scientists, engineers and others involved do not lack imagination nor does the industry lack innovation.  The PV technology breakthroughs have been in development for at least a decade.  Innovations in balance of systems, including storage, in deployment and in the utility grid are crucial at this juncture.  In fact, innovations in the way electricity is delivered are crucial – variable sources can be managed and in doing so we will all, genuinely, breathe easier.

 7.     Quality concerns are overblown

Sadly, the PV industry, which used to hold itself to strict quality standards, eased these standards a bit as prices for PV modules crashed.  Just a few years ago, B, C and even D grade modules were not acceptable.  The cliché “you get what you pay for,” could be rephrased, “you get what you settle for.”  It is time that the industry returned to its high quality roots – solar is the best, highest quality electricity generating technology.

8.     PV cell and module manufacturing outside of Asia is dead

To paraphrase Mark Twain … reports of the death of manufacturing outside of Asia certainly seem to be true, but in fact are due to a complex series of choices by industry participants that include governments choosing (over time) to either support domestic manufacturing or not to support domestic manufacturing, the choice of governments to support a domestic market or not to support a domestic market, the choice of technology manufacturers to price aggressively for share or not to price aggressively for share, among others.  For an incentive driven industry with significant downward price pressure to promise to be a close-to-free electricity source and then enter into an aggressive pricing strategy in order to gain market share the pertinent and rhetorical question is, was it worth it?  Aggressive pricing is not new, and regional leadership has shifted over time from the US, to Japan, to Europe and now to China.  A more widely disbursed technology manufacturing sector would result in a healthier industry.  Given today’s low margins and continuing failures, a controlling share in the current market hardly seems like success.  Regional leadership comes and goes.  Even now there are solar startups developing technologies that address the industry’s twin goals of lower cost and higher efficiency. 

Table 2: Regional PV Cell/Module Shipments 1997-2011

9.     New multi-gigawatt markets in Latin America and South Africa are the future of solar

The markets in Latin America and South Africa are not new but they have increased in size.  As these are low or no incentive markets with tender or PPA rates set by bid, these markets are highly unlikely to be highly profitable. Markets where the rates are set by tender serve to hold down the already low price of solar technology – and this, like it or not, is not a healthy trend.  Companies working in Latin America report that despite reports of gigawatt levels of demand, many of the announcements will not happen. It might be a good thing for the solar industry to remember the lessons of the FiT.  Basically, under the subheading When Good Markets Go Bad … when markets overheat, they usually collapse; better slow and steady growth in these emerging markets than a huge success followed by a spectacular failure. 

10.  Moore’s Law applies seamlessly to PV technology price/cost

Gordon Moore, Intel, observed in 1965 that the number of transistors per square inch on an integrated circuit doubled every year.  Today, as the time to double has slowed, this is held to be ~18 months.  For the PV industry Moore’s Law is taken to mean that the price of a PV module will decrease by ~20% when industry growth doubles. In the early days of the solar industry, when annual growth was in the low megawatts this was more-or-less the case and so, it was easy to accept what is basically an if-a- then-b comparison between Moore’s Law and solar prices.  The PV industry surged past the megawatt mark with the advent of the FiT incentive model -and is now slowing, meanwhile, prices continued behaving erratically.  During the early years of the FiT prices increased and when prices decreased it was due to aggressive pricing – and government subsidized manufacturing – and not to a theory that has been somewhat arbitrarily applied to the PV industry. PV technology manufacturers have little control over raw materials, consumables, equipment costs and demand/supply side incentives.  Prices – in any industry – are a not-entirely logical result of market forces.  Price behavior for any industry is erratic at best and Moore’s Law is a poor fit for it.  Perhaps the industry could rethink the appropriateness of how Moore’s Law is applied to PV and all solar, and consider efficiency as a more appropriate metric. Better yet, the solar industry could review its history and come up with a metric that supports its own innovation history and that comes from observing its technology development overtime. 

 11.  Solar is a commodity

Electricity is a commodity, natural gas is a commodity, wheat is a commodity – a solar electric system is the means of electricity production that can be owned by individuals, communities, governments, investor groups and others. When an installation, this is specifically PV but can also be CPV, is close to the community it not only generates clean electricity it educations and promotes community involvement.  Multi-megawatt installations (CPV, CSP, PV) far away from the load have multiple problems on the way to success, one of which is the very distance from the load.  The generation of anonymous kilowatt hours effectively commoditizes solar.  This is not an argument against large scale solar, this is a sector that certainly has its place.  Better the industry consider why people buy things in the first place.  Transportation consumers buy cars for many reasons, and the car typically makes a statement about its owner.  A car is not a commodity; the gas that goes into the car is a commodity.  In the case of solar, the fuel for a solar system – the sun – is necessary for life.  Commoditize that!      

12.  Anti-dumping tariffs and regulations jump-start local manufacturing

Nope. Even more important, protectionism cuts many different ways and almost never results in a true winner.  The economy is global, better partners than adversaries. 

 13.  The saving grace of a worthwhile cause

So the battle has gotten tougher, the margins tighter and the naysayers louder. Meanwhile, climate change is now obvious to most, with even the doubters finding alternate explanations difficult to come by.  The twin goals of achieving lower manufacturing costs and higher efficiencies remain, and even now in the midst of a painful consolidation, startups work to find answers, universities continue R&D and new business ideas percolate.  Despite all the difficulties the saving grace of the worthwhile cause that is solar is, well, worth it.

Concerning the hog farmer, I don't think the complementary aspect of biogas and PV electricity was stated sustinctly. For baseload demand, you don't need PV storage. Storage of biogas is easier than storage of electricity. We don't know what his personal load demand is nor do we know what he can get for selling electricity but in general such intgegrated technologies on a distributed network can make a lot of sense if one can get past the existing biases.

@ Barry. I was going to ask, but it looks like your Mom knows you talk like that. I think it is best to take an integrated approach to implementing technologies. In a business operation, processes are interrelated and making a change in one effects the others. It is amazing how efficiency can be increased by taking this approach.

If you think about it, William's choice is not between processing manure with Black Soldier Flies and PV, but rather processing the manure by creating methane or using Black Soldier Flies. I'll give you the benefit of the doubt and say you are trying to make a useful contribution to this discussion.

Bill - now I'm confused. Is it better to go the "black soldier fly larvae to process manure" route -- or PV? To paraphrase my mother, "shit or get on the roof."

@ William Butler. I also live in NC. My name is Bill but I am using my Sweetie’s computer right now. Glad to see you making methane. Some options to look at are: 1. Thermal storage in the form of hot water or stored in the ground like geothermal (for heating buildings, your home and water) and chilled water or ice for air conditioning and 40 degree refrigeration. For any thermal loads that can be met this way, the collection (thermal collectors) and storage is less expensive. Then look at the PV. 2. Compressed air storage. The compressed air can be used to power a motor that can replace any electric motor. 3. Using Black soldier fly larvae to process manure. The larvae are a high grade livestock and fish food and can be processed into a biodiesel fuel and a high grade compost is also produced.

'8. PV cell and module manufacturing outside of Asia is dead' It is if you want it to be but it doesn't have to be the case. With highly automated manufacturing, labor is a small component of cost; however, high automation requires consistently high volume. Once you have volume, particularly a large local market, you can offset labor costs against transportation costs. This involves a major commitment and patience as well as supportive government policy. In today's market that means facility footprint >400 MW/a but it would be very difficult to do this right now given the excess of capacity in the market. The opportunity is that a substantial portion of capacity is in small marginal producers that can and will be run off: even in China, go big or go home seems to be the game plan. But it wouldn't be easy: the reality for North American PV manufacturing is that much of the commodity supply chain extends into Asia where, not surprisingly, industry suppliers are co-located with major manufacturers. A healthy domestic industry can't happen overnight. Also, the current WTO onslaught against domestic content rules and subsidies constrains the degree to which governments can facilitate domestic manufacturing. However, this is definitely a myth however popular it may be with modern day American Luddites.

'6. An industry-changing new PV technology is just around the corner' That's always true but not in the way that most people would like to think - new technologies haltingly infiltrate into the business they don't suddenly leap out. The first semiconductor solar cell was made in 1883, the first silicon cell in 1954. Almost every aspect of PV manufacturing has changed in the 20+ years of personal hands-on experience - a few things roll out quickly but most arrive slowly and many 'promising' technologies founder on practical realities. The reality behind this myth is that there are no magic bullets while many would like to believe there are i.e. just one single new technology that will trump all the rest.

'10. Moore's Law applies seamlessly to PV technology price/cost'. Wanting to draw an analogy between PV and semiconductor manufacturing is a fallacy in itself. Having worked both patches, I can say there is little in common between the two in terms of logisitics, manufacturing tools and processes. Except for deposition there is really little in common and even there the parameters are vastly different. Forcing this analogy is a bit like comparing the business models of jewelry stores and grocery stores.

"I am a NC Pork Producer and we produce renewable energy from our swine waste"

Do you also utilize the stench of pig farming [ammonia] for growing tomatoes like the Danes?

http://agrotech.dk/en/projects/pig-city-zero-emission-and-odour-free-pig-production

What pigs do that solar cannot is produce an abundance of baseload energy from waste.

Hey William,

I wrote a (too) long article on how to predict your payback. If you want you can scroll to the bottom and download the spreadsheet :-)

Nice article.

Myth 10 about Moore's Law not applying to the solar industry is true, however the "experience curve" as in most industries does apply, where each doubling of the total volume will result in lower prices.

I liked your explanation with Myth 11. With comparing the solar installations to cars. This is a diverse market where areas with good sunlight should use concentrated photovoltaics (CPV). Also if panels are on your rooftop, since the space is limited, the higher efficiency panels probably make more sense while for a large bulk maegawatt scale electrical generation, space may not be as big of an issue.

William, maximum return on investment is obtained by maximum reduction of your electrical bill in most cases based on your actual power load usage. Today, both pole mounted optically enhanced full tracking systems and electronically and optically enhanced rooftop fixed systems are designed with storage and lower cost hardware to match your actual load use and lowest capital costs.

Typically, utilities will charge you retail rates but pay you wholesale rates. Thus by including electrical storage you actually maximize your return on investment. No since producing power at times that you are not using it, just to sale it to the utility and then have to buy power back when you need it. My company provides storage as part of the rooftop or pole mounted full polar tracking systems. Thus we can provide the most economical method to provide you power that meets your actual needs. jnistler@yahoo.com

I am a NC Pork Producer and we produce renewable energy from our swine waste by using our biomethane gas to run a generator and put electricity back into the grid.
I am also interested in a small solar farm. (1-5 MW) I usually hear the too expensive, and too long to wait for a pay back excuses, and it is a cause for concern. When one is looking at a 4 or 5 million dollar minimum investment in a project such as this you have to know up front that it will cash flow. The above article and comments are encouraging. At this point I do think that solar investments can be economically feasible and I would appreciate any bits of information that could help me make a final decision on going forward.

Incumbent energy producers (fossil fuels) and distributors (utilities) continue to win the messaging war when they characterize solar as "expensive." In almost every public forum I hear them say something like "solar is nice, but of course it is too expensive..." These misstatements are too often accepted by our industry, repeated by journalists, and become part of the conventional wisdom about solar.

It's our fault when our industry is tarred by the "too expensive" brush. Every individual in our industry needs to push back when they hear these untruths. Solar panels have a 1.5 year energy payback, in many locations less than a 7 year simple payback, and with financing a positive cash flow from the first year. Now that hardware costs have dropped so significantly we need to stand up and explain to everyone -- especially policy makers and journalists -- that solar is the cheapest, cleanest and most reliable source of energy.

Sadly, the myth concerning unreasonable energy payback times still lurks in the dark corners of collective popular consciousness. While modules produced in 1970 may have taken decades to recover their invested energy, today's modules pay back in a couple of years (see Fig. 2 of http://www.clca.columbia.edu/240_SolarToday%20June12_c.pdf ).
