SPIRE ESTABLISHES SPIRE FLORIDA INC.

Spire Solar Florida plans to take advantage of the State's renewable energy initiatives and a variety of solar energy incentive programs to offer utilities and other energy users access to Spire's PV systems integration skills.

BEDFORD, MA - September 9, 2003 - Spire Corporation (Nasdaq: SPIR), today announced the incorporation of Spire Florida, Inc., whose initial mandate will be to provide solar electric systems to the sunshine state's renewable energy market. The new company's initial venture, Spire Solar Florida has opened an office located at 6798 Crosswinds Drive, Suite D105, St. Petersburg, Florida 33701, to introduce Spire's photovoltaic (PV) manufacturing technology and systems integration capabilities to Florida utilities, municipalities and alterative energy suppliers.


Spire Solar Florida plans to take advantage of the State's renewable energy initiatives and a variety of solar energy incentive programs to offer utilities and other energy users access to Spire's PV systems integration skills. Support for the new operation will be provided from Spire Corporation's headquarters in Bedford, Massachusetts, as well as from the Company's Chicago-based systems engineering group.

Spire Solar Florida will be modeled, in part, on the Company's successful solar systems business in Chicago, where Spire has teamed with the City of Chicago and ComEd, the local utility, to provide large, grid-connected photovoltaic systems for schools, museums, commercial buildings and multi-family developments. An integrated PV module manufacturing business, Spire Solar Chicago offers complete PV turnkey services ranging from systems design and installation to after-sales service and performance monitoring.

Steve Hogan, Executive Vice President and General Manager of Spire Solar, Inc., stated, "To jump start the Florida operation, we will offer our solar electric systems integration expertise gained during three years of systems installations at more than 30 sites in Chicago. We are especially pleased that the office has been established by Jeremy Jones, a Senior Systems Engineer with extensive experience in our Chicago systems group."

Roger Little, President and CEO of Spire Corporation, added, "Our strategy is to capitalize on the Company's broad-based PV module manufacturing and systems integration know-how by partnering with utilities, municipalities and independent power producers who recognize the merits of distributed energy systems based on solar power. With Florida Solar Energy Center and utilities such as JEA and Tampa Electric promoting wider utilization of green energy, Florida presents a promising market opportunity for Spire."

"The establishment of Spire Florida, Inc.", Mr. Little continued, "positions us to look at Spire Biomedical, as well as Spire Solar opportunities in Florida. Florida is one of the most promising states for developing Spire's Solar and Biomedical activities, and we plan to participate in the expected growth of both sectors."

RBI Solar - Dahlia Has You Covered

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
