Orange County Convention Center's new one-megawatt photovoltaic (PV) system, the largest rooftop solar installation in the Southeast. Solar panels will span the length of five and a half football fields, generating 1,300 megawatt-hours of electricity per year - greatly reducing the center's carbon footprint and electricity costs. The unveiling will kick off the Green Cities Florida Conference, a two-day event providing fresh, innovative and useful information to businesses, communities and governments interested in embarking on the road to sustainability or improving their current efforts.
