Solar energy harvesting problem lies in cost and efficiency of the solar cell. Thisresearch offers alternative for efficiency boost by increasing cell illumination. Using v-trough reflector light is augmented to push solar cell voltage and current yieldsurpassing the actual non-concentrator condition. Conversion efficiency and productivityincreases as the addition of both. V-trough experiment employing reflected light selection mechanism is done toraise polycrystalline solar cell output with 413 milliwatt of power and 72 cm2 area. Theresearch design was carried out using Taguchi method referring to three level and threecontrol factor Orthogonal Array with response factors of voltage and current. The threecontrol factors are alpha angle, reflector height and reflector color. Solar cell outputwith and without v-trough usage are also compared in order to know the enhancement level. The findings revealed that both responses were affected by the control factorsand optimum condition achieved on A3B3C3 parameter settings which is 65° alpha angle,15 cm reflector height and a red reflector color. Result shows 1,48% and 20,88% solarcell voltage and current increase in v-trough implementation over the non-implemented.After the use of 37,96mW solar cell power then the Rp2.860,00 cost increase in v-troughconfiguration can be redeemed due to Rp75,35/mW cost reduction.
