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.
Renewable energy – including wind, solar and biomass resources – accounted for all new generating capacity added in the U.S. in January, according to the Federal Energy Regulatory Commission’s (FERC) latest Energy Infrastructure Update.
The 1.231 GW of new U.S. electrical generating capacity entering service in January represented nearly a threefold increase in new renewable energy generating capacity compared to January 2012, when wind, solar and biomass provided 431 MW of new capacity.
Wind energy accounted for the largest share of the new capacity in January, with six new units providing 958 MW, followed by 16 units of solar (267 MW) and six units of biomass (6 MW). No new generating capacity was reported for any fossil fuel (i.e., natural gas, coal, oil) or nuclear power sources.
Renewable sources now account for 15.66% of total installed U.S. operating generating capacity, and wind energy represents 5.17% of the total. Other renewable resources include water (8.5%), biomass (1.29%), solar (0.38%) and geothermal (0.32%). In comparison, natural gas accounts for 42.37% of total operating generating capacity, followed by coal (29.04%), nuclear (9.23%) and oil (3.54%).

Sustainable Future is excited to help with Solar Energy International (SEI) training in Knoxville April 8th, 2013 – April 12th, 2013. This five day course is great for those wanting to get into the solar industry or those that need to prepare for the NABCEP entry level test. Included in the course will be some “hands on” exercises at the Sustainable Future solar park, with class room work being held at a local hotel. This course will be taught by two very seasoned solar installers who have installed systems all over the country. This course will provide an overview of the three basic PV system applications, primarily focusing on grid-direct systems. The goal of the course is to create a fundamental understanding of the core concepts necessary to work with all PV systems, including: system components, site analysis, PV module criteria, mounting solutions, safety, and commissioning. The course will also cover the basics of sizing a residential grid-direct system, wire sizing, overcurrent protection, and grounding – all of which will be expanded upon in PV202.
Prerequisites: Before participating in the PV101 in-person workshop, students are required to complete the self-paced PV 101 PREP online component (included in price of PV101, you will automatically be enrolled in PV PREP Online at the time you register for PV101).

Promoting Solar PV Deployment Through Micro-Investments
This conference is hosted by the American Solar Energy Society to which TSEA is the Tennessee State Chapter. Established in 1954, the nonprofit American Solar Energy Society is the nation’s leading association of solar professionals and advocates. Our mission is to speed the transition to a sustainable energy economy.
Global Photonic Energy Corp. (GPEC), has created a thin-film solar cell that has the ability to provide electricity at grid parity or the cost of traditionally provided electricity.
Gallium Arsenide (GaAs) is a better photovoltaic candidate than silicon reaching 30% or better efficiency. Problem with Gallium Arsenide cells is that they are very expensive to manufacture in large sizes. Instead these cells are used in concentrating solar PV arrays where the sun image is concentrated some 500 times focusing the light onto a small millimeter sized GaAs cell.
Dr. Stephen R. Forrest of the University of Michigan said the breakthrough, presented at the Fall Meeting of the Materials Research Society, is the result of substantially reduced production costs. It is based on a patent-pending invention that reuses the same Gallium Arsenide wafer multiple times to produce solar cells. This unlimited wafer reuse approach to conventional “epitaxial lift off” technology that typically leads to wafer damage, and hence only a very limited number (1 to 2) of wafer reuses, has the potential to reduce the cost of a typical Gallium Arsenide solar cell to below $1 per Watt (peak).
“This exciting development implies that ultra-high efficiency solar cells based on Gallium Arsenide can eventually produce electricity at or below grid parity.” Dr. Forrest stated. “Using integrated solar concentrators and our adhesive-free, cold-weld bonding technology to plastic substrates, we estimate electricity could be produced as low as $0.45 cents per Watt, compared to traditional grid parity of $1 per Watt.”
GPEC is excited by the discovery. With this new discovery, the cost structure is dramatically reduced and can be used in numerous applications. The high efficiency, light weight and flexible solar cells are deployed on roll up plastic sheets. GPEC anticipates their use in spot powering vehicles, mobile military equipment and satellites, and off-grid locations. The company has big plans and want to license its intellectual property in order to commercialize the technology. To date, GPEC has a total of 425 patents.
The reason that solar panel prices are so low is because the supply of panels have exceeded the demand. The supply was projected on the historical growth of solar which had been rising at a spectacular rate, but governments around the world have fallen into a recession mode and have trimmed or eliminated the supports for the solar industry. Examples here are the elimination of the 1603 grant and the rising need to reduce solar set-asides in the renewable energy credits in many of our states. It started with Spain, then Italy and then Germany. China has cut back on the manufacturing of panels and many of their businesses as well as those around the world have seen their profit margins disappear. The spot price of polysilicon had reached a low of $13 per kilogram; way below the manufacturing cost of roughly $20. The smaller cell manufacturers and the panel makers have been failing narrowing down the supply of panels. The results are beginning to show up with the spot price of polysilicon rising to $16 on the spot market. With the rise in polysilicon prices will come an increase in the cost of cells and finally the cost of panels. So, if you can afford to buy panels, now is a good time. So, unless we increase the demand substantially, the price will remain static or rising until the scale of manufacturing expands significantly.

Power for 2014 delivery in Germany and France dropped to records as rising solar output is expected to cut demand for other electricity sources.
German power, a European benchmark, fell as much as 1.5 percent, according to broker data compiled by Bloomberg. The equivalent French contract declined 0.3 percent.
Electricity for Germany next year lost 65 cents to 43.30 euros ($57.93) a megawatt-hour, it’s biggest decline since March 6, according to broker data compiled by Bloomberg. The French equivalent lost 15 cents to 46.20 euros.
As much as 18 percent of electricity demand may be replaced by solar panels not connected to Germany’s grid, reducing demand for other sources by 6 to 10 percent by 2020, Per Lekander, a Paris-based analyst at UBS AG (UBSN), said in a research note.
“The unsubsidized solar growth should drive wholesale power prices further down,” he said.
