Enphase Surpasses 1GW of Microinverter System Shipments

Enphase Ships Over 100MW During Fourth Quarter 2013

PETALUMA, Calif., Jan. 15, 2014 -- Enphase Energy, Inc.

(Nasdaq:ENPH), today announced a company milestone of 1GW (AC) of
Enphase(R) Microinverters shipped worldwide to date. In 2008, the company

years the company has brought to market three succeeding technology
generations while also expanding internationally.

During the fourth quarter of 2013, Enphase shipped 107MW (AC) of
microinverter systems. This is an increase of 14 percent compared to the
third quarter of 2013 and an increase of 30 percent year-over-year.

"We continued to see very strong business momentum during the fourth
quarter, mainly driven by a healthy residential solar market in the U.S.,"
said Paul Nahi, CEO of Enphase. "During the fourth quarter, shipments
exceeded 100MW of microinverter systems for the first time, marking another
record quarter."

Enphase previously announced on November 5, 2013, that it expected revenue
