Photovoltaic (PV) energy is a renewable and harmless energy which offers many advantages. However, solar energy is an extreme intermittent and inconstant energy source. In order to improve the photovoltaic system efficiency and utilize the solar energy more fully, and the DC current and DC power vary with the irradiation and module temperature, it is necessary to study the characteristics of photovoltaic Ⅰ-Ⅴ and P-Ⅴ according to the external factors. This paper presents the analysis of characteristics of photovoltaic Ⅰ-Ⅴ and P-Ⅴ according to the irradiation and the module temperature. The results show that the DC current and the DC power of the photovoltaic system are increased along with the increasing values of irradiation and module temperature.

Plant factory, which considered as a novel plant production system preparing for the climate changes such as a global warming or raining, is an attractive year-round production technique of leafy plants regardless of place or season. The environmental factors of air temperature, relative humidity, nutrient, CO2 concentration, light intensity or quality inside the factory system influencing on growth have been reported. In this study, effects of light-environmental control of quality or intensity were investigated on growth of red curly lettuce ( Brassica rapa) seedlings with different four growth ages (0, 10, 20, and 30 days-old after transplanting) inside the factory system. ‘Tukksum’ red-curly lettuce which developed two true leaves was used as a plant material, and the seedlings were cultured under nutrient solution of 1.5 ds m-1 EC and 5.8 pH for 10 days after light exposure of 50, 100 or 230 μmol m-2 s-1. Light-emitting diodes of Red, blue plus red, and blue plus white were used, and fluorescent light was considered as a control. In 0 day-old seedlings after transplanting, dry weight and number of leaves under blue plus red light of 50 μmol m-2 s-1 light intensity for 10 days increased 28 and 19% comparing with the control, respectively. Increasing of fresh and dry weights in 30 days-old seedlings was significantly stimulated by blue plus red and red light. However, leaf pigmentation was inhibited by the red light regardless of the different growth ages and promoted by the mixture lights. Under 230 μmol m-2 s-1 light intensity, number of leaves, fresh and dry weights were greater by mixture-light exposure on 20 days-old seedlings. On 30 days-old seedlings, increment of dry and fresh weights was also affected by the mixture light. Leaf pigmentation was significantly inhibited by the red light regardless of the different light intensities in all the growth ages. Higher growth and pigmentation could be achieved at 20 and 30 days-old seedlings cultured under the mixture lights of blue, red, or white. It is concluded that light intensity should be controlled according to growth ages for growth and pigmentation, but rather stable control during culture period, and monochromic red is not suitable for leaf pigmentation of red curly lettuce in plant factory system.
