Why is SunPower Doing So Well While Others Fail?

SLevy: Every solar investor wants to maximize its return on investment. In my judgement the reason for Sun Power’s success is they provide a product with the greatest return on investment over the long term. What I mean by long term is tens of years and beyond. Their panels produce the highest output power per area of any other manufacturer. We know that the life of the premiere monocrystalline panels is beyond 40 years. Using 40 years in computing the Levelized Cost of Energy results in more realistic results in cost per kilowatt-hour.

PV energy provider (PVEP) SunPower has revealed that demand exceeded its ability to supply product and services in the first quarter of this year.

The PVEP reported that it had exceeded revenue, gross margin and earnings forecast for the first quarter of 2013, while generating significant free cash flow of US$216 million, including lease financing, which was sold out in the quarter.

SunPower noted that due to several massive PV power plant projects in full swing in the US, strong demand for lease financing rooftop business in the US and ongoing PV module partnership success in Japan that was set to continue throughout the year, it was sold out for the year.
Management noted that its project development business was on course to provide US$3.5 billion in revenue and approximately US$1 billion in gross margin from 2013 through 2016.
Importantly, SunPower said that during the first quarter, the company was awarded 65MW of rooftop projects in France during a recent tender process, which had been supported by majority company owner, Total.

With demand increasing, SunPower said that it increased cell production in the quarter to 208MW, up 36% from the previous quarter. SunPower recognised 172MW of sales, while it shipped 186MW. Total module production capacity remained at 1.2GW. Full capacity was expected to be reached in the second half of the year.

New Music City Center Solar Project

LightWave installs 211 kW Solar on New Music Center

Construction on the $585 million facility began in January 2010 and was completed on April 30, 2013. The Music City Center totals 2.1 million square feet, double the space available in the current convention center. Already more than 100 meetings and 800,000 room nights have been booked.

Project completion will be celebrated on May 19 and 20 at the Music City Center Grand Opening with Nashville Mayor Karl Dean. Celebration includes open house tours, free street party and concert featuring Sheryl Crow, The Time Jumpers with Vince Gill, Fisk Jubilee Singers, and more. Major Dean will give his State of Metro address on Monday, May 20 at 10 a.m.

LightWave Solar recently completed the installation of a 211 kilo-watt (kW) solar system for the Music City Center, and it is the largest solar installation in Nashville.

Installed within the guitar shaped structure on the roof, the system consists of 845 solar panels and four inverters weighing 1,800 pounds each. The system will generate approx. 271,000 kilowatt-hours per year, enough electricity to power the electric vehicle charging stations and lighting for the building. Over 25 years, the clean electricity will offset nearly 5,000 tons of carbon dioxide emissions, the equivalent of taking 920 cars off the road.

Retail Electric Business Predicted to Loose Market Share

The Edison Electric Institute has issued a report predicting that there will be a change in the market share for retail electric business if the present trend towards distributed renewable energy continues at it’s rapidly changing mix of standard electric power production and the increasing percentage of renewable energy sources, particularly solar PV continues to evolve. The report dated January 2013 entitled “Disruptive Challenges: Financial Implications and Strategic Responses to a Changing Retail Electric Business” was authored by Peter Kind of Energy Infrastructure Advocates. The key premise is that the increasing inclusion of solar PV will reduce market share for the electric power industry which will lead to higher risk for investors. The result of a higher risk will be increased cost for borrowing money for the power industry. The report sites two similar industries that were drastically changed by market forces and regulatory changes: the airlines and the telephone (AT&T) industry. The report concludes that near term actions are to “institute a monthly customer service charge”, develop a tariff structure to reflect the cost of service and value provided to DER (solar PV) customers and to “analyze revision of net metering programs in all states so that self-generated DER (solar PV) sales to utilities are treated as supply-side purchases at a market-derived price.”

It is my suggestion that the industry adapt itself to incorporate solar PV in such a way as to improve its retail electric business position. My advice to the industry: constructively adapt renewables into your energy mix: it is not a curse but a blessing.

City to Require Solar in New Construction

Every new housing development must average 1 kilowatt per house. Not here, but in California. California is a light-year ahead of Tennessee and most of the country when it comes to solar acceptance.

The Lancaster, California City Council unanimously approved changes to the city’s zoning code that require housing developers to install solar with every new home they build.
This is the latest piece in what Republican Mayor R. Rex Parris described at the City Council meeting as a plan to make Lancaster “the solar capital of the universe.”
Lancaster’s now official Residential Zones Update specifies, along with a range of green building provisions, that new single family homes meet minimum solar system requirements in the same way that they must meet minimum parking space requirements.
“The purpose of the solar energy system standards,” it reads, “is to encourage investment in solar energy on all parcels in the city, while providing guidelines for the installation of those systems that are consistent with the architectural and building standards of the City.” It is further intended “to provide standards and procedures for builders of new homes to install solar energy systems in an effort to achieve greater usage of alternative energy.”
Residential homes on lots of 7,000 square feet or more must have a solar system of 1.0 kilowatts to 1.5 kilowatts. Rural residential homes of up to 100,000 square feet must have a system of at least 1.5 kilowatts.

U.S. installs more than 3,300 MW of solar PV in 2012

U.S. photovoltaic installations in 2012 increased 76 percent over 2011 numbers to 3,313 MW, with an estimated market value of $11.5 billion, according to GTM Research and the Solar Energy Industries Association (SEIA)’s “U.S. Solar Market Insight 2012 Year In Review.”
Cumulative PV capacity operating at the end of 2012 was 7,221 MW. The U.S. accounted for 11 percent of all global PV installations in 2012. The report predicts the U.S. PV market will grow 30 percent in 2013 with 4.3 GW of new PV installations anticipated during 2013 across all market segments.
Installed prices dropped 27 percent last year and at least 13 percent in each market segment (residential, non-residential and utility).
California led the U.S. in 2011 and 2012 with 1,033 PV installations in 2012, compared to 577 in 2011. Arizona moved up one spot this year to No. 2 with 710 installations in 2012. New Jersey dropped from second in 2011 to third last year with 415 installations in 2012, Nevada jumped from tenth to fourth with 198 installations and North Carolina rounded out the top five with 132 installations.

Ten Years Shows Silicon Solar Modules Maintain 97% Original Performance

Even after a decade, aleo solar modules show only minimal age-related performance reduction (degradation). MBJ Services, an independent service provider, assessed a 5.44-kilowatt system near Bremen (Germany) which had been in operation for nearly ten years. They measured each of the 34 aleo modules’ performance with the help of a flasher. The result: an average degradation level of 2.73%. Photovoltaic system planners generally presume performance losses of 0.5% per year – but the aleo modules only degraded by about half that much. Read More
