Soltec Releases New CPV Module at Solar Power International Expo

November 1, 2009

Soltec Renewable Energies has presented its new ultra-high-concentration PV (CPV) module, the SOLTEC GP-1500, at the Solar Power International Exhibition (Anaheim, Oct. 27-29). The release follows more than two years of research and development.

Soltec-GP1500According to Soltec, the main features of these modules are high efficiency, wide acceptance angle, compact size, cost effectiveness and high reliability.

The optical design, based on the well known Cassegrain reflecting telescope, uses mirrors to concentrate sunlight approximately 1500 times over triple-junction cells of the highest efficiency.

The SOLTEC GP-1500 modules have 80% more power density than conventional modules, which allows a significant reduction in the Levelized Cost of Energy (LCOE), the company says.

Soltec expects to achieve grid-parity once multi-Megawatt production volumes are reached. Low cost optics and high module efficiency – over 25% – will make this possible.

The company is active in turn-key photovoltaic installations, providing everything from the planning stages, to EPC, finance and maintenance of the plants. It additionally may provide single or dual axis trackers, according to the project. Soltec is in the process of opening up offices in the US to serve the North American market.


SolFocus Installs First Solar Array for 3 MW Spanish CPV Project

January 17, 2008

SolFocus, manufacturer of solar energy solutions including concentrator photovoltaic (CPV) systems and Spain‘s Institute of Concentration Photovoltaics Systems (ISFOC) announced two days ago the installation of the first CPV array in the ISFOC’s 3 MW project in Castilla-LaMancha.

The ISFOC project is sponsored by the government of Castilla-La Mancha. Its program supports participating companies by carrying out important R&D efforts on their installed systems. This includes studies and norms, developments on measurement technology for large systems, reliability testing, maintenance, and analysis of solar radiation and energy produced.

The companies awarded the first 1.7MW phase of CPV pilot plants were Isofoton (Spain – 700kW), SolFocus (US – 500kW), and Concentrix (Germany – 500kW).


800_sol3g.jpgIn November 2007 a 1,3 MW second phase to complete the program was awarded to Sol3g (Spain – 400kW) and Concentración Solar La Mancha (Spain), EMCORE Corp. (US) and Arima Eco (Taiwan) – 300kW each.

According to Dr. Pedro Banda, Director General of the ISFOC, “This is a very important occasion as it brings the industry one step closer towards commercial deployment of CPV technologies. For this unprecedented and ambitious program, the ISFOC has selected CPV technologies that are the most advanced and have the brightest futures.” He added, “SolFocus’ first installation marks the official launch of the power-generation phase of the program.”

SolFocus, with European headquarters in Madrid and United States headquarters in Mountain View, Calif., has over 40kW of test arrays installed at various sites.

The ISFOC was established in 2006 to be a center of reference on the power, reliability and productivity of commercial CPV systems. The innovative approach taken by the ISFOC is becoming a model for similar projects under consideration around the world.



Taming the wind and sun

Everyone that has heard about La Mancha, knows from the musical and the Quixote novel that it is a sun-drenched land of windmills that might be giants (or not).

With all that sun and wind, the thinking of the locals seems to have been”If we got them, let´s put them to good use! ”

Correspondingly, the landscape in the region is dotted here and there with the iconic modern version of the windmills, that make a stellar appearance in the movie “Volver” by Almodovar.

Trying to profit from the other natural resource in abundance in the area, regional authorities are pushing forward an ambitious plan to boost solar energy. Besides the plants mentioned in my previous posts in Puertollano (solar thermal power), the city is the site for the Institute of Concentration Photovoltaic Systems or ISFOC (website in Spanish only).

The Institute launched a RFP for the development of plants using Concentrator Photovoltaic (CPV) technologies for a total capacity of 2.7 MW. The companies selected to build the plants are:

These commercial plants are going to be grid-connected and sited in different provinces of the region of Castile-La Mancha. The headquarters of ISFOC will house demonstration plants (200 KW) for each of the technologies employed in the commercial plants.

Concentrator Photovoltaic systems are experiencing a very interesting moment worldwide, with record gains in efficiency by Spectrolab (Boeing) and many companies taking their products to market. Spectrolab has an agreement with Solar Systems (Australia) to provide it with 500,000 concentrator solar cell assemblies to be used in remote rural communities.

Guascor Foton is one of the pioneers in Europe in this technology, the development of which stems from a partnership with the American company Amonix. Guascor Foton installed the first commercial high concentration CPV plant in Europe at the campus of the upm.jpgPolytechnic University of Madrid. This project was developed in collaboration with the Institute of Solar Energy from the UPM and the Spanish Government Agency for Energy Diversification (IDAE).

The company is also working in three aditional solar plants using the same technology with a joint capacity of 3.5 MW in different parts of Spain.
