Câmaras de Torres Vedras e Peniche com programa de incentivo à instalação painéis solares
Os habitantes dos concelhos de Torres Vedras e Peniche que residam em moradias podem, a partir de hoje, candidatar-se a um programa de instalação de painéis solares para reduzirem custos energéticos (...) em parceria com um banco e uma empresa de instalação dos equipamentos. (...) Os interessados poderão concorrer até 31 de Janeiro de 2009.

Segunda maior central solar do mundo começou hoje a funcionar em pleno no Alentejo
A Central Solar Fotovoltaica de Amareleja, que desde meados de Março produzia e injectava energia na rede eléctrica nacional de forma parcial, através dos primeiros 2,5 megawatts (MW) instalados, começou hoje a funcionar em pleno, disse Francisco Aleixo, director-geral da Amper Central Solar, empresa que instalou e gere a central e propriedade da Acciona (...) Com uma capacidade total instalada de 46,41 megawatts (MW) distribuídos por 2520 seguidores solares azimutais, equipados com 104 painéis solares cada um, a central de Amareleja situa-se num terreno de 250 hectares, perto daquela vila, considerada "a terra mais quente de Portugal", devido aos recordes de temperatura máxima no Verão.

First Solar Panels Piling Up?
[S]ix key First Solar customers aren't able to install the solar panels quick enough. Those customers, including EDF Energies Nouvelles, Conergy, Ecostream, Phoenix Solar and Colexon, might have an even tough time doing so in 2009, when First Solar is due to ship even more panels to them than it did in 2008. (...)
Moreover, we don't expect these modules to move out soon, given weakening economics, lower natural gas prices, higher interest rates, and tougher underwriting requirements," wrote Jonathan Hoopes, managing director of energy technology research at ThinkEquity. (...)
Hoopes estimated First Solar shipped about 208 megawatts worth of panels to the six customers between the second half of 2007 and 2008. He combed through company announcements and presentations and figured that roughly 105 megawatts, leaving 103 megawatts in their inventories.

Solar Fraud Could Eliminate Spanish Market
A government investigation has uncovered many incomplete projects that were reported as finished by a September deadline. Those projects could qualify for the new 500MW cap for 2009, blocking new project applications (...) The National Energy Commission, or CNE, began investigating these reports in late October (...) After checking 287 solar farms, investigators found that only 97 of the projects (roughly 44 percent) were legally completed by September.
(...)Spanish newspaper El Pais published a story on Dec. 7 about the government investigation, noting that six government workers resigned after evidence showed they gave solar energy development permits to relatives.

Gas supply challenges for PV
Strong solar and LCD panel growth is straining global supplies for silane, the most critical raw material , but most of the supply chain captive by polysilicon manufacturers. (...) Future solar applications will use more silane than any other application that demands silane today -- he estimates that the future requirements for silence will be ~67,000tons/year of silane, about double the amount used for semiconductors and LCD manufacturing (excluding polysilicon production). (...) "Due to economic issues, the ramps that were planned for 2009-2010 are slower than anticipated, so for now we've covered the (silane) gap," (...) but the long-term issue is whether production capacity can keep up with demand -- "How much confidence do we have in demand forecast[s] to invest $100M up-front in a silane manufacturing plant?"

Clouds over the Solar Power Industry
The economic crisis has weakened demand for everything from polysilicon to rooftop panels, just as manufacturers have spent billions expanding production. The overcapacity has caused prices to plummet and left the industry financially exposed. A number of companies—especially startups—may not survive a shakeout that could last 18 months or longer. (...) The causes of the downturn are complex and interrelated. As the price of oil plunged from its peak last summer, solar and other forms of renewable energy became relatively less cost-competitive—dampening demand from industrial, commercial, and residential customers. At the same time, the credit squeeze has made it harder for customers, whether power companies or energy-conscious homeowners, to finance solar projects. Some also are holding back in anticipation that solar equipment prices will fall even further.
