What is SOLARAYS ?

What is SOLARAYS? • Unique System that combines Electric and Thermal generation energy in only one module. • It makes a maximum accuracy tracking of solar position whithout using any motors, fluids or electrical consumption (passively ‐ tracked HCPV system), allowing stable and continuos energy generation at maximum power, dissimilar to generation of isolated peak power of the existing photovoltaic systems, with costs of generation lower than any other existing technology, either renewable o conventional technology. (Patent System) • Very light System (50% less than current Systems of Electric and Thermal generation energy, that requires differentiated installations) and takes up much less space for generating the same kwh. • The technology can be installed on every surface (multifamily buildings, tilt roof in individual homes, industrial warehouses and ground-mounted installations to feed-in the electrical grid). .

Qué es SOLARAYS? • It reaches electrical efficiencies higher than 33% (double the efficiency in relation to conventional Silicon solar panels, whose highest quality and cost versions extend maximum 21%) and combined efficiencies (electric and thermal) of 72%. All this certificated by the Instituto de Energía Solar - Madrid (IES), which constitute, one of the four existing accredited Institutions all over the world more developed in concentrator photovoltaic investigation. • Increases more than 30% the Energy generated compared with conventional silicon solar panels. • Takes all the advantages of CPV and eliminates the need of accurate and expensive solar trakers. • Including generation of thermal uses, it doubles the efficiency of CPV and triples the efficiency of conventional silicon solar panels.

Qué es SOLARAYS? • 30% cost reduction for the energy generated in comparation with conventional fixed tilt solar panels. • SOLARAYS module is highly economically competitive, as can operate by generating just electricity, thermal energy or combining the production of both of them (electric and thermal energy).

Concentration Photovoltaic Technology (CPV) � Efficiency of cells > 40% � Use of all the whole solar spectrum � Solar cells operates at 1000X of solar concentration � Minimum Area � Great production of electrical energy in areas of high irradiance and temperature � Used in satellites for its Eff / cost.

Passively-tracked HCPV System Solarays Solution CPV TECHNOLOGY NEEDS ACCURATE AND EXPENSIVE SOLARAYS TECHNOLOGY OPERATES AS ULTRA- UNITS WHICH ARE ONLY INSTALLABLE ON THE EFFICIENT TRACKED SYSTEM WITHOUT THE GROUND NECESSITY OF ANY KIND OF NITIRS OR EXTERNAL CONTROLS. OUR TECHNOLOGY CAN BE INSTALLED ON EVERY SURFACE.

Thermal Integration Multi-junction solar cells can operate at 90ºC obtainning efficiencies that triple the silicon conventional. It makes possible the simultaneos cogeneration of electricity and heat and the trigeneration using one stage absorption cooling. The System can be adapted to thermal uses in industrial sector for 250ºC temperatures because of the high solar concentration levels achieved.

(11 858 103,2-1009). • In process in India and Brazil. •Recently, a new PCT patent protection has been filed and will enter in National Phase all over the word.

System Efficiencies and advantages Adapted Design to suit end-users as much as 72% Combined Efficiency possible by: � Quick and easy installation because of the integration of the estructure in the panel, and due to the low load of wind highly reduces the anchorage needs. 40% Electric Output Energy � Much more types of roofs can be used. � Stable energy generation throughout the day, permitting 60% Thermal Output Energy a much higher percentage of self-consumption and fewer batteries � Low weight. � Low visual impact. � Lowest cost of energy generation

System Integration It can be installed on every surfaces. Very low visual impact and weight, making it suitable for many more roofs.
