Arrowhead Energy Letter of Appreciation


March 12, 2009


I want to thank you and your firm for taking the time to educate us on your microinverters. As our firm's system designer, I have spent an immense amount of time researching methods for building optimized PV systems, and your product is what I like to refer to as a "No-Brain-er." Not only does your product eliminate all of the issues with finding the optimal balance of array size to inverter, but the increased lifespan of the Enphase Inverter has brought system payback down by 3-6 years!


The professionalism I have experienced in dealing with your firm far exceeds any other company I have dealt with in the PV industry. At Arrowhead Energy Corp, we look forward to exclusively using Enphase Inverters in all of our systems and promoting your name to our fellow installers in the good state of North Carolina.


We look forward to building a long-lasting relationship with your company. Please contact me if our firm can ever be of service to you in any way. Thank you once again.

With best regards,

AAES Letter of Appreciation


December 15, 2008


To Enphase Management:


I want to thank you all at Enphase for helping make our projects a success and I would strongly encourage other solar companies to utilize your products. We appreciate the Enphase inverters for their simplicity, reliability, and performance. I have found that we save 4-6 hours of skilled labor on a typical installation, utilizing the Enphase inverters. Installation of the inverters is very simple and quick; and we no longer need to worry about the logistics of mounting a large inverter on site or running DC wiring inside the building envelope.


The Enphase inverters enable us to design systems with less concern for string sizing, partial shading issues, mismatching, or space restrictions. These benefits save time during the design process, and help eliminate potential mistakes. I am impressed with the unique features of the monitoring system, and I was pleasantly surprised by the support provided by Enphase staff, which is hard to find these days.


Thank you,
