  1. OFF-Grid Telecom Station By: Chris Hickey, Ian Antolik, Raimondo DeVincentis

  2. Table of Contents • Task Description • Design Approach • Going Green? • Design Matrix • Design Specs • The Hut • Overall Design • Conclusion

  3. Task Description • Problem • Population of Wiruca, Nicaragua needs a more reliable and efficient cell phone service • Task • Designing a system to power telecom towers in an off-grid application utilizing the GE sodium metal halide battery at a low cost, while minimizing environmental impact.

  4. Design Approach • Disposable income of $10/month/family • Cost efficient service • No Electricity • Need for off-grid power source • Current cell phone tower/system cost: $300,000-$500,000 per tower/equipment and $90,000 for the energy system • 1.7 Cordobas/hr for electricity • Mountainous area • Not suitable for wind power • Claro-cell phone service provider

  5. Going Green? • Because of the need for power from and the requirement for an off-grid application, green energy is the best option because of its sustainability and eco-friendliness. • Initial costs of green energy systems are higher, but have a greater return in the time-value of money.

  6. Design Matrix

  7. Decision Matrix

  8. Design Specs • 9 kW photovoltaic array • 33 kWh battery capacity

  9. The Hut • Heating and ventilation of hut • qs+qm+qso=qw+qf+qvo-qvi • 90W +750W+134250W=-12416W-934W-9373606W+X • X=9522046W=9025BTU • Need for a 10000BTU a/c unit • Materials accounted for include: • Studs, drywall, asphalt shingles, metal storm door

  10. Overall Design Cell Phone Tower Solar Panel Hut

  11. Conclusion • Use efficient solar power • Use cheap, but effective building materials • Cost analysis • Solar panels: $27,323 • Light bulbs: $15 • a/c unit: $300 • Batteries: unknown • Building materials: $13,000 • Dump energy sales: $14/year • Equivalent telecom equipment/tower: $300,000-$500,000 • Provides cheap, green energy in an off-grid application to the people of Wiruca
