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.


Titan Tracker finishes a CPV project for the ISFOC

TITAN TRACKER in pv system

TITAN TRACKER has just completed a demonstration project for the delivery of a solar tracker for concentrating  photovoltaic systems (CPV) at the ISFOC facilities, a research center that is a world reference in that field, from the Castilla-La Mancha region in Spain. TITAN TRACKER is a technology firm specialized in the manufacturing and commercialization of dual-axis solar trackers. The product (Titan tracker 122-219 ATR Precision) is a new concept in solar trackers and has been developed for flat-plate and high concentrating photovoltaics (CPV),  offering high reliability and extreme accuracy.

It breaks with the usual design based on mounted-pole systems, and is claimed to offer improved benefits during the whole life-cycle of the installation. This cutting-edge technology provides a provides adjustable accuracy better than 0.01 degrees, thanks to the stiffness and rigidity of its 3D structure and a geometry based on five support points, making it possibly the most accurate and reliable solar tracker around the world.

It move continuously in azimuth, whereas the rest of the trackers move  intermittently with thousands of starts and stops every day, generating a stress which may seriously compromise  their reliability.

More advantages of the ATR Precision trackers:  The foundations are minimal, therefore important savings in materials (up to 35% less concrete and 85% less steel) can be achieved. Formwork is not needed, thereby reducing the need of specialized staff.

The main results of this project will be presented by TITAN TRACKER at the CPV Summit, an International Conference about concentrating solar technologies, which will take place in San Diego (California) next February (3 and 4).

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).

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.
