TECNOLOGIA CPV E DELLE CENTRALI SOLARI PER AZIENDE ELETTRICHE PREVEDIBILE

 

Per le utility, la prevedibilità è cruciale, specialmente in relazione all’energia solare e ad altre risorse rinnovabili.

Le centrali solari Amonix hanno una prevedibilità comprovata, fondata su un’esperienza più lunga di tutti nostri concorrenti. Infatti, i nostri impianti fotovoltaici a concentrazione (CPV) producono più energia per ettaro di qualsiasi altra centrale solare.

Recentemente l’azienda ha celebrato il suo ventunesimo anniversario, testimonianza pluriventennale di successi nell’installazione di centrali solari. La tecnologia Amonix viene realizzata sul campo da oltre 16 anni e in questo periodo di tempo abbiamo sviluppato sette generazioni di sistemi caratterizzati da prestazioni ed economicità sempre maggiori.

I risultati effettivi rappresentano il fattore cruciale di differenziazione. La prova è nell’affidabilità delle operazioni giornaliere, con la produzione di energia rinnovabile, pulita tramite i nostri impianti CPV, tra cui spicca l’ultima generazione, basata sulle celle solari multigiunzione, che sostituiscono la più vecchia tecnologia del silicio.

Questo vantaggio è illustrato da grafico dei risultati qui sotto, che si riferisce a oltre un anno di dati di produzione reali. Il grafico mostra che i risultati effettivi hanno uno scarto non superiore a 1% dalle previsioni relative al modello Amonix.

 

Predictability Graph

La prevedibilità dipende da due fattori: affidabilità e manutenzione ordinaria. Per questo motivo, Amonix progetta i suoi impianti affinché siano così robusti da tollerare condizioni ambientali veramente avverse.

I dati prestazionali mostrano anche l’elevata affidabilità degli impianti Amonix, che presentano tempi di fermo minimi nel corso di un anno. E in caso di problemi, gli impianti sono riparabili sul campo.

L’altro fattore principale è la manutenzione ordinaria. Sebbene gli impianti Amonix non richiedano acqua per la produzione di energia elettrica, è utile pulirli periodicamente. Un MegaModule® pulito è un MegaModule efficiente. Ai fini della pulizia occorrono solo 1.233 kl di acqua per MW a corrente continua di capacità dell’impianto.

    CPV Intelligence Brief 17 – 30 April 2013

    Amonix converts 36% of direct sunlight into electricity

    California-based Amonix, a designer and manufacturer of concentrator photovoltaic (CPV) solar power systems, has converted more than 36% of direct sunlight into electricity.

    A module showcasing Amonix’s latest-generation CPV technology has been in outdoor testing from late February to April of this year. During this period, the Amonix module demonstrated a peak operating efficiency of 36.2% measured on March 14, 2013 with a DNI of 876 W/m2, an ambient temperature of 16°C and instantaneous wind speed of 1 m/s, breaking the previous 34.2% peak efficiency set by Amonix in May 2012.

    Over the entire testing period, the Amonix module earned a National Renewable Energy Laboratory (NREL) outdoor efficiency rating of 34.9%, a new world record, under international standard operating conditions for concentrator photovoltaics of 900 W/m2, 20°C ambient temperature and 2m/s wind speed, breaking the previous 33.5% rated efficiency record also set by Amonix in May 2012.

    The module uses Boeing Spectrolab 40% high efficiency solar cells and Amonix’s proprietary CPV technology to achieve world record performance.

    SEAL BEACH, Calif.--April 26, 2013--

    Amonix Inc., the leading designer and manufacturer of concentrator photovoltaic (CPV) solar power systems, announced today that it has successfully converted more than 36% of direct sunlight into electricity. A module showcasing Amonix's latest-generation CPV technology has been in outdoor testing from late February to April of this year. During this period, the Amonix module demonstrated a peak operating efficiency of 36.2% measured on March 14, 2013 with a DNI of 876 W/m(2) , an ambient temperature of 16degC and instantaneous wind speed of 1 m/s, breaking the previous 34.2% peak efficiency set by Amonix in May 2012.

    Over the entire testing period, the Amonix module earned a National Renewable Energy Laboratory (NREL) outdoor efficiency rating of 34.9%, a new world record, under international standard operating conditions for concentrator photovoltaics of 900 W/m(2) , 20degC ambient temperature and 2m/s wind speed, breaking the previous 33.5% rated efficiency record also set by Amonix in May 2012. The module uses Boeing Spectrolab 40% high efficiency solar cells and Amonix's proprietary CPV technology to achieve world record performance.

    This result continues Amonix's long history of leading the world in solar module efficiency, having been the first to convert over 1/3(rd) of the sun's energy in May 2012, and the first to break 30% module efficiency in 2011.

    Western dreams: The Alamosa Solar project, the world's largest CPV plant
    Solar Server

    The Western United States is a big place. The sheer scale of the landscape overwhelms; in many states you can drive hundreds of kilometers in any direction, through prairies, forests, mountains and deserts, without encountering a city.

    This land has always attracted ambitious individuals; after the Native Americans came trappers, prospectors for gold and silver, farmers, ranchers, those fleeing religious persecution, and more recently, hippies and entrepreneurs.

    In the Western state of Colorado, on the high prairie of the San Luis Valley, facing the wall of the San Juan Mountains, is one of the most ambitious solar projects yet undertaken. Above the rabbitbrush and greasewood are a series of 15 by 21 meter arrays of lenses, rising on hundreds of metal poles like an alien orchard.

    This is Cogentrix' Alamosa Solar project, the world's largest concentrating photovoltaic (CPV) project, which we bring you as Solar Server's November 2012 Solar Energy System of the Month.

    Report: CPV could be 30% cheaper than PV by 2016
    PV Tech
    Leggi tutto

    Improved technology and decreasing costs could boost concentrated PV (CPV) installations to 3GW worldwide within four years, according to research.

    A report by IMS Research said that advances in CPV technology would drive down costs by 16% annually, prompting an increase in installations from today’s cumulative total of around 160MW to 3GW by 2016.

    “With companies such as Solar Junction breaking cell efficiency records and Amonix capable of producing 34.2% efficient commercial modules, and focused on driving down system prices, acceptance of CPV as a utility-scale generation method is predicted to accelerate,” said report co-author and IMS Research Analyst Jemma Davies.
