| 光伏最佳方阵倾斜角与方位 The Angle and azimuth of the pv optimal array 为了保证本项目收益最大化，并且也为了组件安装简便与效果美观，通过专业光伏模拟软件分析得出，此地的最佳太阳能倾斜角度为26度，及朝正南向倾斜26度安装。这样可保证系统发电量在全年周期中的最大化。 In order to guarantee the project income maximization, and also for component installation is simple and beautiful effect, and through professional photovoltaic simulation analysis software, the best solar Angle here is 26 degrees, and 26 degrees toward the south to the installation. This ensures that the amount of power generated by the system is maximized during the full year cycle. 另考虑到光伏支架强度、系统成本、屋顶面积利用率等因素。在保证系统发电量降低不明显的情况下(降低不超过1%)尽可能降低光伏方阵倾斜角度，以减少受风面做到增加支架强度，减少支架成本、提高有限场地面积的利用率。 Other factors such as the strength of the photovoltaic support, the system cost and the utilization rate of roof area are given. Under the condition of the guarantee system capacity to reduce is not obvious (no more than 1%), as far as possible to reduce photovoltaic phalanx Angle, in order to reduce the surface wind do increase the support strength, reduce support costs, improve the utilization rate of limited site area. 经分析得出，本项目建议倾斜角约为17度左右(屋面正南面倾斜角度)。 According to the analysis, the proposed Angle of slope of the project is about 17 degrees. 5.光伏方阵前后最佳间距设计 The optimal spacing design of the pv array 为了追求太阳能发电系统全年的最佳发电量并尽可能的提高屋面利用率，我们在此要求在冬至日(每年的12月22日或12月23日)当天9:00至15:00，光伏方阵列不会互相遮挡，此时的前后间距即为最佳间距。 In pursuit of the year's best solar power system capacity and improve the utilization rate of roof as possible, we hereby request at the winter solstice (December every year December 22 or 23) 9:00 to 15:00 on the day, photovoltaic phalanx column will not block each other, the distance between before and after is the optimum spacing. 经专业PV软件模拟可知，光伏方阵倾斜角度17度，组件阵列与阵列间最低点间距保持在5M，冬至日当天9:00至15:00，光伏方阵列基本不会互相遮挡。 By professional PV software simulation, the photovoltaic phalanx 17 degrees tilt Angle, low spacing between component array and array in a 5 m, 9:00 to 15:00 on the day of the winter solstice, photovoltaic phalanx column basic will not block each other. |
