Introduction
How does Solar fit into the Whole School Sustainability Model?
A Whole-School Sustainability system framework is organized into the three components of schools: organizational culture, physical place, and educational program.
4
Introduction
• Organizational Culture• Schools are a centerpiece in the community and provide a vehicle to
demonstrate civic values.• Physical Place
• A school’s physical place—including the built environment, surrounding natural environment, and the resources that flow through the school—provides both the context for an educational experience and a visible representation of school values.
• To best harness the power of physical place, it must be engaging and active, be progressively more efficient, and embody systems that enhance human, environmental, and economic health.
5
Introduction
• Physical Place continued• Solar technologies provide a unique educational opportunity for teachers
and students. Access to solar arrays lets students connect classroom learning to a real, working technology. Students learn about solar power, electrical systems, and energy markets.
• Educational Program• Connecting people, place, and purpose, a school’s educational program
brings the vision and mission of a school to life.• Solar technology dashboards provide real world learning opportunities
which align with current standards.

ENVIRONMENTAL SCIENCE & HONORSRenewable & Non-Renewable Resource
(11/4-11/15)
SC.912.L.17.11 - evaluate the costs and benefits of renewable and nonrenewable resources, such as water, energy, fossil fuels, wildlife, and forests. ~ Evaluate possible environmental impacts resulting from the use of renewable and/or nonrenewable resources ~Infer how human activities (including population growth, pollution, burning of fossil fuels, habitat destruction, and introduction of nonnative species) may impact the environment ~ Explain how the use, protection, and conservation of natural resources by humans impact the environment from one generation to the next ~ Focus on the environmental costs and benefits of using those resources and not on identifying examples of renewable and nonrenewable resources
SC.912.L.17.11 •Do the benefits outweigh the costs of using renewable and nonrenewable resources? Why or why not?•Which resources can be used with the least negative impact on the environment? Why do you think so?•Which resources are used with the highest negative impact on the environment? Why do you think so?•How can humans reduce their negative impact on the environment?
Standard Guiding questions to help elicit higher order thinking

Solar Around OCPS
• Olympia HS• Funded through a Progress Energy/Florida Solar Energy Center solar energy
grant program • Installed in 2008 and saves approximately $275 per year in electric costs
• Waterford ES• Funded through a Progress Energy/Florida Solar Energy Center solar energy
grant program• Installed in 2007 and saves approximately $215 per year in electric costs
• Zellwood ES• Solar thermal system, for hot water, installed per the school’s redesign• Saves approximately $300 per year in electric costs
17
Warranty, Operation, and Maintenance Considerations• Solar panels and components are typically warranted for up to 25
years by the manufacturer.
• Solar panel systems are required to withstand Hurricane force winds per the Florida Building Code.
• Solar panels do not require regular maintenance.
• The system can be monitored remotely to quickly identify issues and be used as an educational tool.
