Abstract |
In the array installation method of photovoltaic power generation system, horizontal array has higher power generation efficiency but its site utilization rate is lower at 30 to 40%. On the contrary, the vertical array has the advantage of providing site utilization rate of 100% or more depending on the number of vertical arrays. In this study, the silicon-based crystalline modules with power generation efficiency of 16.9% were arranged vertically in 8 series and 8 parallel arrays to produce 10kW scale. The vertical array was placed in the outer part where foreign matters such as fine dust is naturally washed away by the rain and the amount of power generation was analyzed in consideration of the inclination angle, azimuth and the shadow length at the meridian altitude that affect the power generation amount. As a result of the analysis, the tilt angle of the array installation in the vertical alignment in the latitude of 35°~37° was proposed through simulation. |
