Abstract

In this paper a Photovoltaic (PV) system was designed for the Port-Margot School Solar Project in Haiti. This off-grid system consists of PV panels, inverter, battery storage and other components such as fuses, dc/ac disconnects and transformers [1]. Sizing the PV to fit on the roof was determined. The battery storage and inverter were chosen to be installed in the school building. The expected energy production was compared with data file from NASA website. The KW PV system was chosen to be the most effective and demonstrating renewable technologies and reducing the electrical load of the school.

Highlights

This project is led by the Ministries of Aides International Organization, and its partners United Solar Associates, LLC, Solar World Co. will deliver donations at the most appropriate facility
System Investment Content This PV system has installed capacity of 6.92 kW, investment include PV panels, off-grid inverter, batteries, charge controller, AC circuit breaker, wires, PV panel mounting rack, power shed, labor fees and so on which are presented in Table 2 and Table 3
The payback time of this system is 10.71 year, compared to the average payback time for the developing countries, which is 6.76 years. This Photovoltaic system is designed for SOLARWORLD donated Haiti school project

Summary

Introduction

This project is led by the Ministries of Aides International Organization, and its partners United Solar Associates, LLC, Solar World Co. will deliver donations at the most appropriate facility. Solar electricity will allow for much improved cooling and ventilation in the offices and classrooms. The steady flow of electricity will provide power to the administrative offices and improve productivity with peripherals such as computers, copiers, printers, etc. According to the client’s requirement, there are 6 perspectives in PV system model selection: Data collection, Electric appliance load calculation, Battery packs selection, PV array selection, Spacing between rows and Con-. The school located in Port-margot where is not far from cap-haitien. CAP: Battery Capacity, Ah; D: Autonomy days; L: Daily electricity consumption, kW∙h; ηout: Total efficiency; Take inverter efficiency for 0.92 and charge controller for 0.98.
