But the reason electricity is considered high-grade energy is that its more versatile. Heating water is great, but its only one job. Converting sunlight to heat and electricity, and doing both efficiently, would be a double-win. Give it a short payback period and youve hit the trifecta! A PVT system includes a solar thermal collector (as shown above) that mounts underneath a photovoltaic panel. A typical PV cell has an efficiency of 15% under ideal conditions.

The data confirm the regeneration and photocurrent recovery of the -FGPVs after accelerated degradation of the dye molecules by illumination with intense UV light. The violet-colored regions represent the periods of intense illumination. The dotted arrows are guides to the eye. The washing and activation steps were performed for 5hrs each. Supplementary information Photovoltaic systems based on photosensitive organic dye molecules could be a simple and economical alternative to conventional solar cells, and have been actively developed for decades 1 , 2 , 3 . The best examples of such devices are the common dye-sensitized solar cells (DSSCs) 4 , 5 , though other systems based on a dye-embedded hydrogel or naturally derived photoactive molecules have also been reported recently 6 , 7 , 8 . Since the organic dyes are generally susceptible to light, high temperature or water, however, the degradation of photoactive molecules in the dye-based photovoltaic systems could be a critical problem, which leads to deterioration of the long-term performance of these photovoltaic cells 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 . Photosystems, which are organic photoactive complexes forming the core of plant leaves involved in photosynthesis, also suffer from light-induced damage.

Aiea-based Hawaii Energy Connection had the second-largest number of permits pulled in July, after Utah-based Vivint Solar. Email | Google+ | Twitter | LinkedIn The solar photovoltaic industry, one of the fastest growing sectors in Hawaii, may be showing signs of slowing down a July was the third straight month showing a year-over-year decline in permits issued on Oahu, according to new statistics collected by Marco Mangelsdorf , president of Hilo-based ProVision Solar. There were 1,163 solar PV permits issued by the City and County of Honolulu last month, which actually was an increase from 980 permits issued in June and 932 permits issued in May, but fewer than the 1,466 permits issued in July 2012. The peak month for permits issued during the past year-and-a-half was October, when there were 2,433 permits issued. Among the top solar companies, Utah-based Vivint Solar led the way, followed by Aiea-based Hawaii Energy Connection, Honolulu-based Alternate Energy, California-based SolarCity and Honolulu-based RevoluSun , which rounded out the top five in permits pulled from January through July. SolarCity rose to the top in terms of the year-over-year percentage increase in permits pulled with an bump of 125 percent. Hawaii Energy Connection (59 percent), Vivint Solar (54 percent), Maui-based Haleakala Solar (33 percent) and Alternate Energy (18 percent) rounded out the top five in this category.

Hawaii’s solar photovoltaic industry sees permit decline for third month in a row
JinkoSolar, Cenergy Power build photovoltaic system at farm 08/09/2013 By Editors of Electric Light & Power/ POWERGRID International Sponsored by Photovoltaic manufacturer JinkoSolar Holding Co. supplied 2.2 MW of solar PV modules to HMC Farms, which will span across 390,000 square feet of ground space and enable HMC to hedge against rising electric utility charges on two cold storage and packaging meters. The solar power plant was developed and is being built by California based Cenergy Power, an integrator of solar power systems. The solar power array will be built at the facilities of HMC Farms, a grower, shipper and packer of peaches, plums, etc. The giant ground mounted solar system is designed to produce over 3.4 million kWh of energy annually, which will reduce the plant’s energy needs by 68 percent and provide an attractive 4-year unlevered return on investment. JinkoSolar distributes its photovoltaic products to a customer base in the global PV market, including Germany, Italy, Belgium, Spain, the U.S., France, Eastern Europe, China, India, Japan, South Africa and other countries and regions.
