KYOCERA Solar Modules Exceed Performance Expectations at San Diego`s Alvarado Water Treatment Plant

Megawatt System Produces 115% of Expected Electrical Output Since Feb. 2007
Installation

SCOTTSDALE, Ariz.--(Business Wire)--
If you`re considering investing in a large-scale solar electric generating
system, but need assurance about the economics or reliability of solar power,
please read on.

Kyocera Solar, Inc. today announced that its 1.135-megawatt (MW) solar array at
the Alvarado Water Treatment Facility in San Diego, Calif., has exceeded
performance expectations consistently since it began operating in February 2007,
as documented by power generation data.

"The 6,128 Kyocera solar modules at the Alvarado Water Treatment Facility have
performed at 115 percent of expected output since their installation," said John
Helminski, Emerging and Renewable Technology Program Manager for the City of San
Diego. "Initially, we anticipated 1.6 million kilowatt hours (kWh) annually -
but it`s been producing just over 1.85 million."

The Alvarado facility will increase its water treatment capacity by 67 percent
next year, from 120 million gallons per day to 200 million. To alleviate the
cost of the expansion, the City of San Diego became one of the first in the
nation to adopt a Power Purchase Agreement. Also known as a "PPA," this contract
between an electricity producer and a host site owner helps curb energy costs in
a sustainable manner.

The PPA allows the Alvarado Water Treatment Plant to host - without owning - the
Kyocera solar modules. The facility`s PPA partner owns, operates and maintains
the entire system. For a period of 20 years, the City of San Diego has agreed to
purchase every kilowatt hour that the system produces, at a fixed price, with an
annual cost escalation of just one percent. That`s much lower than the expected
annual increase in utility rates.

"Under our PPA, solar electricity is already costing us less per kilowatt hour
than utility power," Helminski explained. "Additionally, utility rates typically
rise by at least 2.5 percent each year, which promises further savings." Taking
a conservative approach and compounding the difference between 2.5 percent and 1
percent annual rate increases, the City estimates savings of about $325,000
during the course of its 20-year PPA. If rates rise an average of 4 percent per
year, the savings will be about $650,000.

The system`s environmental benefits are equally impressive. The solar
installation occupies previously unused space atop the concrete roofs of three
water storage reservoirs. Its annual power output represents the energy
equivalent of about 2,640 barrels of oil. That`s enough to offset about 580
metric tons of carbon dioxide each year - an impact comparable to about 400
acres of green forest.

"From our perspective, the system has performed flawlessly and beyond our
expectations," Helminski continued. "It`s the City of San Diego`s goal to be
both environmentally sensitive and to ensure that our projects make economic
sense. This installation helps us to achieve both goals."

The project reflects a major initiative to increase California`s renewable
energy mix to 33 percent by 2020. Consequently, the Alvarado Water Treatment
Plant is attracting interest from other municipalities considering solar power.
"I`m out there once or twice a month giving a tour," Helminski stated.

The City of San Diego, already a solar energy leader, is now pursuing PPAs for
its other water treatment facilities. "We`re extremely proud that San Diego
leads California in both the number of solar energy installations as well as in
the amount of electricity generated using photovoltaic panels," said San Diego
Mayor Jerry Sanders. "Solar panels on the Alvarado Water Treatment Plant are a
major step toward meeting our goal of 50 megawatts of solar power within city
limits by 2013."

According to Ian Knox, Kyocera`s Southern California sales manager, large-scale
solar electric generating systems are becoming commonplace in many regions of
the globe. "Kyocera solar panels are ideal for municipalities and water
treatment facilities because of their high efficiency and quality construction,"
Knox stated. "Kyocera is committed to environmental preservation and providing
quality solar energy solutions to the world."
