Ayiti Èd - Solar Power

print this page
(back to main page)
This page will have the information on power needs and Solar (or other?) Power for Duchity projects

Haiti Electrical System:

https://en.wikipedia.org/wiki/Electricity_sector_in_Haiti Haiti has the lowest availability of electrical power in the Western Hemisphere.
Electrical Plug/Outlet and Voltage Information for Haiti (Repiblik d Ayiti):

  • Voltage: 110-120 Volts 60 Hz (Same as U.S./Canada)
  • Primary Socket Types: North American Non-Grounded , North American Grounded

http://news.nationalgeographic.com/news/energy/2013/13/131223-earthspark-solar-micro-grid-haiti/ a new model for connecting homes and businesses to clean, reliable power using smart meters, solar panels, and a small, independent power grid is being put to the test in Les Anglais.


PowerBudgets-Duchity</span>

This section needs to figure out what actual POWER (Watt-Hours) would be needed in Duchity for the projects related to the current Vermont Haiti Project opportunities.</span>

Solar Lights?? http://waka-waka.com/sun-sharing-alliance/


Cell Phone Recharging:</span>

Galaxy SIII: consumed 12.3 watt-hours to charge, taking 2 hours and 26 minutes. Maximum wattage was 6.6 watts, with an average of approximately 5.0 W.</span>
iPhone 5: consumed 9.5 watt-hours to charge, taking 1 hour and 50 minutes. Maximum wattage was 6.3 watts, with an average of approximately 5.0 W.</span>

? What is a highly-efficient system to allow recharging of Cell Phones and other small devices in the Duchity community.



SOLAR POWER: Available Sun power in Haiti

The solar assessment for Haiti produced by 3TIER for Worldwatch includes three different measurements for solar irradiation: global horizontal irradiance (GHI), direct normal irradiance (DNI), and diffuse horizontal irradiance (DIF).

Measurement Description Application
  • GHI Total solar radiation per unit area that is intercepted by a flat, horizontal surface. (Solar PV installations) </span>
  • DNI Total direct beam solar radiation per unit area that is intercepted by a flat surface that is at all times pointed in the direction of the sun. </span>
  • CSP installations and installations that track the position of the sun </span>
  • DIF Diffuse solar radiation per unit area that is intercepted by a flat, horizontal surface that is not subject to any shade or shadow and does not arrive on a direct path from the sun. Some PV installations that are best suited to diffuse radiation (DIF is included in the GHI calculation)</span>


Based on the specific conditions of Haiti’s solar resource and the suitability of specific solar technologies, this assessment
focuses mostly on the country’s GHI measurements for solar PV installations and DNI for solar water heating applications.

Power Storage: Batteries

LiPo Type Battery Source: http://www.optimumnanoenergy.com/
Load-Acid batteries are still the most cost-effective:

What About Wind??

Wind MAY be a viable power source for Duchity. This might be particularly true for an FM Transmitter located in a high location.
It should be noted that no on-site data were available for this study. The data came from raw model outputs, and should be used to guide future on-site studies for project development. Meteorological onsite data should be collected for at least one year before project construction begins.
NOTE: We MIGHT be able to borrow a Wind Power Assessment system from RenewableNRGSystems in Vermont.
