<![CDATA[This paper is to review existing knowledge on energy requirements for manufacturing photovoltaic (PV) module and system. Estimate energy (primary energy) requirements for manufacturing PV module for scenario: Low* and High1. For multi crystalline silicon (mc-Si)a. Low is 4200 MJ/ m2 (mc-Si) or 35 MJ/Wp = 3,395 kwh/Wpb. High is 11600 MJ/ m2 (mc-Si) or 96 MJ/Wp = 9.312 kwh/Wp2. For a single –crystalline (sc-S)a. Low is 6000 MJ/ m2 or 47 MJ/Wp = 4,559 kwh/Wp.b. High is 13900 MJ/ m2 or 109 MJ/Wp = 10.573 kwh/WpEstimate energy production (final yield) for application SHS (50 Wp) multi – crystalline (mc-S) is 65 kwh/Wp/year (1 Wp produce 1,3 kwh/year. Estimate Energy Pay-back Time ,” take energy to save energy”. for Solar Home System Application for over 20 year system life (under 1900 kwh/ m2/year irradiation) are 3-4 years for low scenario and 8 years for high.]]>
