| Introduction : Annex1: Technical specifications of solar PV systems for Samsour Basic Health Unit Laboratory-Bau Locality -Blue Nile State 1. Project Background: - UNDP is planning to provide 6 KW solar system for Basic Health Unit in Bau Locality in Blue Nile State. The Solar system shall meet the following minimum requirements. 2. General Description and Requirements - Solar Irradiance of 6 KWh/m2/day should be used to calculate solar PV output for the Solar Modules The major components should be provided with a letter from the principal manufacturer on the warranty and performance parameters, ratings. In addition, hard copies of operation/maintenance manuals and an accreditation certificate from recognized institution is recommended for each product. - To avoid or minimize theft risks for solar PV panels, anti-theft measure is recommended. - Schematic design of the array mounting structure and wiring diagram should be provided for the solar PV systems and local grid connection if required. 3. Solar system requirements 3.1 Solar Photovoltaic Module requirements: - Mono or Poly Crystalline Silicon Solar cells should be used in the solar module that are used for Solar lighting application. Minimum recommended size of solar PV module is 500Wp. - Modules supplied with the Solar PV systems shall have certificate as per IEC 61215-1-1: 2016 – (Special requirements for testing of crystalline silicon photovoltaic (PV) modules) specifications. In addition to accreditation certificate from recognized institute recommended by Global Lighting (World Bank). - Modules must qualify to IEC 61730 Part I and II for safety qualification testing. - The efficiency of the PV modules should be minimum 19%. - The terminal box on the module should have a provision for "Opening" for replacing the cable, if required. - Module Junction should have protection class of IP65, module connector MC4 with 4 mm2 cable with a length of 70% of module length. - Power temperature coefficient of PV modules shall be at most: - 0.043%/0C. - Peak Power of individual module for the SPV at STC must at least be 500 Wp or more. Use of PV module with higher power output is preferred. Module IV characteristics at STC, its temperature coefficient shall be provided for the module. - Each module must be labeled indicating at a minimum: Manufacturer, Model Number, Serial Number, Maximum Power Point Watt Rating (Wp tolerance), Maximum Power Point Current, Maximum Power Point Voltage, Open Circuit Voltage and Short Circuit Current; and temperature coefficients. - The module framing should be such that it permits secure connection to the mounting structure, prevents edge damage, and has the longevity to withstand environmental factors for the duration of the module warranty period. Modules frame minimum dimensions (35 x 35 mm and 1.7 mm) - All PV modules used in the array offered for one project must be of same type, same model, same power rating and same manufacturer. - The PV modules must be warranted to retain at least 90 % of its rated wattage measured at STC for 10 years and 80% of the rated wattage at 20 years. 3.2 Battery system requirements: The batteries shall meet the following requirements: § Iron Phosphate-lithium power battery type with at least 12 years design life in float service. With heavy duty grids, § Battery voltage range 48V-57.6V (Please indicate if you are quoting for different size). § Minimum Battery size 200Ah@C10 § Life cycles not less than 3000cycle at 80% DOD. § Maximum depth of discharge (DOD) to about 80% of rated capacity. § Battery provides consistent performance and long service life. § Usable in a wide temperature range, from -20˚C to 50˚C § Production date should be less than 6 months at installation time. § Higher specific energy density and excellent high-rate discharge |
