TECNOLOGIA CPV E CENTRALI SOLARI PER AZIENDE ELETTRICHE CON BASSI COSTI DI PRODUZIONE DELL’ENERGIA

Le decisioni aziendali relative alle centrali solari per aziende elettriche spesso sono legate in ultima analisi al confronto tra i costi di produzione dell’energia e quelli delle tecnologie tradizionali come pure quelli delle tecnologie di utilizzo di fonti rinnovabili concorrenziali.

In un mercato competitivo, Amonix può presentare fatti convincenti sui costi. Le sette generazioni della tecnologia sviluppata dall’azienda hanno reso possibile l’evoluzione di maggiori capacità degli impianti, più energia generata per ettaro di installazione ed efficienza più alte.

L’introduzione della cella multigiunzione ad alta efficienza è stata un aspetto importante del progresso della tecnologia CPV, portando gli impianti per utility nelle regioni soleggiate e aride quasi sullo stesso piano delle tradizionali reti elettriche.

Il costo della generazione dell’energia elettrica include, per qualsiasi risorsa, quello del carburante, delle operazioni, del capitale e di finanziamento. Sebbene nel calcolo entrino in gioco molti fattori, l’effetto a lungo termine del ‘carburante gratuito’ ottenuto da una risorsa rinnovabile, le maggiori efficienze correlate, la qualità affidabile e adatta per le utility dell’energia così generata e la durata utile prevista più lunga si traducono in costi complessivi inferiori per la generazione di energia tramite il solare.

Gli istogrammi che seguono mettono a confronto le efficienze con altre soluzioni di sfruttamento dell’energia solare come un fattore dei costi di produzione.

    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

    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.
