SunPower modules take top three positions in international yield test

Posted on: April 8, 2013

Published in PV Tech Magazine, March 25, 2013:

US-based module manufacturer SunPower has been ranked in the three top places in the PHOTON International 2012 module yield test.

The company’s SPR-327NE-WHT-D module came in first place with an annual yield of 1,144.1kWh per kW. The performance ratio estimates 95.2% according to a theoretical approach of 1,202 kWh per kW output.

Two of the company’s other modules achieved performance ratio values of 94.9 and 94.8% respectively.

Chinese manufacturer Seraphim Solar System ranked fourth place with its SRP-220-6PB module, with a performance ratio of 93.6%.

Last year’s winner was the REC230AE module made by the Norwegian manufacturer Renewable Energy while this year the module came in 27th out of 151 modules tested.

REC’s module performance ratio has increased from 90.8% in 2011 to 91.4% in 2012 due to favorable weather conditions.

All in all, 109 of the tested modules received a better performance ratio in 2012 than in 2011 and 72 modules achieved a performance ratio of 90% or over.

  • Ralph Lindenhurst

    We are extremely happy with our experience so far with Energy By Choice & Sun Power. From the sales dept. to the installation, everything went very well. Steve, Kelly, Sail & Evelyn as well as the install crew are all very knowledgeable and professional. Thank you for getting us “green” & for enabling us in the near future to tell PSE & G to take their highest energy rates in the country & stick it where the “Sun don’t shine”.

  • Glenn Huntington Station

    Sail and his crew just finished a 9.5KW sun power solar system on my house .I am very happy with the installation and in the way the job was run from start to finish. I chose Energy By Choice because of the high standard that they offered. I am sure that I made correct decision and would highly recommend them.

  • Tallyann West Babylon

    I loved the level of professionalism of all the staff from sales, to installation personal and office staff too. My panels look beautiful and the installation appears clean. I highly recommend using Energy by Choice if you are thinking about going solar. They offer the best product and service of any solar company out there.

  • The Becerra Family Huntington Station

    The whole team is very professional. Sail always answers your questions with professionalism and patience. The crew that installed our panels were on time, efficient, polite and the site was left clean. Our panels are Sunpower, made in USA, which is what we wanted. Energy by Choice were the only ones that offered these panels. Other companies told us we could not afford a system with Sunpower panels and were offering LG panels. Sail offered from the beginning the Sunpower panels. Most import of all this is a local company!

  • Rich Port Jefferson Station

    You’re building a great brand that stands for value and quality, and after doing my homework in picking out a solar contractor, I know I went with the best!

  • Anthony Mattituck

    My wife and I would like to express our sincere thanks and appreciation for your firm’s prompt and professional installation of our solar system. It certainly was a pleasure conducting business with your firm and your service and product knowledge has proven to be second to none.

  • Mike Long Beach

    I intend to stay in touch with Energy by Choice Ltd as new technologies become available and useful.

  • Jerry Baiting Hollow

    From the start your approach was professional, and every step of the way you clearly and accurately represented the parameters of the project. The only surprises that we had were positive ones: the neatness of the work was exceptional and the effect of the solar cells on our electric bill exceeded our expectations.
