Signs OEM Deal With Enphase Energy for Up to 100,000 Microinverters Optimized for Andalay Panels
LOS GATOS, Calif., Feb. 2, 2009 (GLOBE NEWSWIRE) — Akeena Solar, Inc. (AKNS), a leading designer and installer of solar power systems, and Enphase Energy, a leading manufacturer of microinverter products, have announced a strategic partnership to develop and market Andalay solar panel systems with ordinary AC house current output instead of high voltage DC output. Andalay AC panels are expected to cost less to install and provide higher performance than ordinary DC panels. Under the agreement Akeena will purchase a minimum of 5,000 microinverters in each of 2009 and 2010, and Enphase will supply up to 100,000 microinverters to Akeena during this same timeframe. These microinverters will be built into Akeena’s award-winning Andalay solar panels.
Akeena estimates that up to 25 percent of the total costs necessary to design and install a solar power system can be eliminated with solar panels that have integrated racking, wiring and grounding — and that operate with standard AC wiring. Moreover, according to Enphase research, panels outfitted with Enphase microinverters boost solar energy collection by 5 to 25 percent. As a result, systems using Andalay AC solar panels will be less expensive to design and install, and have the potential to provide higher efficiency and better long-term performance for both residential and commercial customers.
“Since George Westinghouse founded the Westinghouse Electric Corporation in 1889, the world’s electric grid has operated on AC power. But the solar industry has always installed DC panels. A big challenge for every solar installer has been to design, install and wire high voltage DC solar panels on rooftops,” said Barry Cinnamon, CEO of Akeena Solar. “Now — finally — we can dramatically simplify the design and installation of a rooftop solar system with standardized AC solar panels.”
“Enphase Energy’s microinverter products provide excellent energy harvest, reliability and remote monitoring capability for solar installations,” said Paul Nahi, CEO of Enphase Energy. “Enphase has made significant advances in next generation power electronics and semiconductor technology which will enable each Andalay solar panel to harvest more energy. In addition, through Enphase’s communication technology embedded in each microinverter, the owner will be able to manage the installation’s performance by remotely monitoring each Andalay panel.”
The agreement with Enphase complements the unique side electrical connectors, integral grounding and built-in racking that are part of Akeena’s patented Andalay technology. The companies plan to collaborate to encourage the solar industry, residential and commercial customers, and standards agencies to adopt AC solar panel technology.
Why AC Solar Panels Are Better Than DC Panels
Historically, solar panels have had DC voltage outputs — just like car batteries. Ordinary DC solar panels are typically attached to rooftops with complicated racking systems, and are then carefully wired and grounded together to generate high DC voltages. These high DC voltages are then routed in dedicated conduit down from rooftops to an inverter. The inverter transforms the DC output from multiple solar panels to the standard AC current used in homes and commercial buildings.
Andalay AC solar panels will be much faster to install than ordinary DC solar panels. With standard AC output from the panels it is no longer necessary to use specialized DC wiring and high voltage components. There is no need to design unshaded “strings” of solar panels, worry about the effects of temperature on the system’s performance, or be concerned about safety issues related to high voltage DC systems. Moreover, parts count and rooftop labor is reduced with the built-in racking, wiring and grounding in Andalay panels.
“Creating an AC solar panel is a logical extension of our Andalay technology, and offers significant potential benefits to both installers and customers. As Akeena Solar transitions to the installation of Andalay AC solar panels in 2009, we look forward to providing our customers with systems that have superior aesthetics, better performance, safer operation and outstanding long-term reliability,” said Cinnamon.
Solar recovery to start, but 2010 outlook dim

* Q3 will show signs of recovery, but pressure remains
* Downstream set to outperform upstream players
* 2010 outlook for sector remains cloudy

FRANKFURT, Oct 23 (Reuters) – European solar equipment makers are slowly emerging from the crisis that has hit the sector, quarterly results will show, but the outlook beyond 2009 will be uncertain due to tight credit and oversupply.
Europe’s solar companies are expected to show signs of recovery when third-quarter earnings kick off next week, with analysts expecting capacity adjustments and the shift of production abroad to benefit companies.
European solars, along with their U.S. and Chinese peers, have to deal with a toxic mix of oversupply of cells and modules as well as a credit squeeze that has triggered a wave of quarterly losses and outlook cuts in the funding-hungry sector.
In addition, Asian competitors that are producing at much lower prices have put heat on their European peers, which are burdened by high labour costs.
But the worst could be over for Europe after companies wrote down the value of their inventories, slashed jobs and shifted production abroad in a bid to stay competitive.
“Q3 reporting should give a strong indication for a recovery of the European solar manufacturing industry, which has been hit over-proportionately hard during the latest crisis,” Oppenheim Research analysts wrote.
