Abstract

Efforts to optimize the electrical output of solar modules by maximizing the intensity of light that falls onto the surface of solar modules using a flat mirror (mirror room). The results obtained revealed that there is increasing output of solar modules. Value of Isc, Voc and the highest P consecutive outs in the amount of amperage 2:13; 20.483 35.34 volts and watts. While the value of Isc, Voc and the highest P out without a mirror room which was 0.78 amperes, respectively; 19.24 volts and 12 watts. Percentage increase in solar module output power can reach 64.22%, the highest efficiency solar module to the mirror room of 13.47% by using low lamp power.   Keywords: Solar Module; Electric Output Optimalization; Mirror Room

Abstract

Using the principle of a box in a black body  covered  with glass crystal, Energy from the sun light which was emit thermal radiation energy of 1000 Watt/m2 at the day light under  Standard Test Condition (STC), the head from the sun light will be speared in the box. Water from the storage tank will circulate without using a booster pump according to the principle thermoshipon to pass through the head collector pipes made of copper in a closed circulation and returned to the water storage tank. With water heating system is expected to have hot water with temperatures above 60o Celsius during the day.   Key word : Solar Energy ; Head Collector; Thermoshipon.

Abstract

Efforts to optimize the power output of solar modules using a mirror. In this study used 2 pieces of flat mirrors as solar reflectors mounted on the right and left of the solar module. Measurement is done by directing the position of solar modules in order to obtain optimum results with a corner reflector 50 0, 600, 700. Based on the measurement results, we obtained at maximum power cost solar modules using the corner reflector 600. The increase in power output compared to 92.7% without using a reflector.   Keywords:  reflector, solar module, output power
