In support of successful biomass production of green microalga Ettlia sp. through attached cultivation, estimation of footprint biomass productivity and optimization of the system was evaluated through comprehensive simulation of solar irradiation. Both temporal and spatial variation of solar irradiation and biomass productivity on the surface of the microalgae-attached panel (MAP) with every combination of design factors (tilt angle, facing direction, height, and distance of the MAP) were closely studied. While an increase in the height to the distance ratio (HDR) increased footprint biomass productivity, fixing the distances at their minimum made steeper tilt angle more favorable for footprint biomass productivity by having a smaller minimum distance. Footprint biomass productivity over the height revealed another important design index, a critical height, where footprint biomass productivity becomes maximum and saturated. Ultimately, three optimum conditions were identified based on economic circumstances: (1) double-side vertically standing MAP facing east/west, (2) 1 m high single-side MAP facing south with seasonal optimum angles, and (3) over 2.5 m high single-side MAP facing west with seasonal optimum angles. Corresponding estimated yearly average footprint biomass productivities were 22, 11, and 11.5 g/m²/day at the height of 3 m, 1 m, and 3 m, respectively.

支持绿色微藻Ettlia的成功生物质生产sp。通过附着栽培，通过太阳辐射的综合模拟评估了足迹生物量生产力的估算和系统的优化。仔细研究了微藻附着板（MAP）表面太阳辐射的时空变化以及设计因子（倾斜角，朝向，方向，高度和距离）的每种设计因素的组合。虽然高度与距离之比（HDR）的增加会增加足迹生物量的生产率，但将距离固定为最小值会使倾斜角度更陡，因为最小距离更短，因此更有利于足迹生物量的生产率。整个高度的足迹生物量生产力显示出另一个重要的设计指标，一个临界高度，足迹生物量生产力达到最大并达到饱和。最终，根据经济情况确定了三个最佳条件：（1）面向东/西的双面垂直站立的MAP；（2）面向南方且季节性最佳角度的高1 m的单面MAP；以及（3）超过2.5 m高单面MAP，面朝西，具有季节性最佳角度。相应的估计年平均足迹生物量生产力为22、11和11.5 g / m² / day分别在3 m，1 m和3 m的高度。
