Abstract—

Research results are yielded proving the great potential of renewable and alternative energy sources of the Republic of Tajikistan, including solar energy, equal to 25 billion kW h per year. The limited use of “green energy” will impose to periodic blackouts of electric consumers in the autumn-winter period. For remedy the emerging lack of energy, a more complete idea of the potential of solar energy is required. The paper provides the estimation of the energy potential of solar radiation in the Pamir regions and the south of Tajikistan. The mathematical model for definition of maximum value of the azimuth angle for the Pamir region is presented. Expressions for an assessment of functioning of two systems and increments of solar radiation and energy potential, by taking into account duration of daylight are offered. Measurements and calculations of monthly, seasonal and annual levels of solar radiation were performed based on the use of two technical systems. It was shown that the energy efficiency of the dual axis solar tracker (DAST) significantly exceeds the efficiency of the static solar system (SSS) especially in the autumn, spring and summer seasons. A comparative analysis of solar energy production and the efficiency of two systems with the use of a solar tracker for a biaxial tracking system and a fixed system is given. It is shown that the annual productivity of the DAST compared with the SSS is on average by 30% higher. In the autumn, the movable system can generate 80% more energy relative to the stationary arrangement of solar panels. Assessment of the solar potential of the regions of Tajikistan proves the feasibility of using this potential as suitable resource for the development of energy, complementing hydrogeneration.

使用太阳追踪器估算该地区太阳辐射的能量潜力

摘要—

产生的研究结果证明，塔吉克斯坦共和国的可再生能源和替代能源（包括太阳能）具有巨大的潜力，相当于每年250亿千瓦时。有限使用“绿色能源”将迫使秋冬季的用电者周期性停电。为了补救正在出现的能源短缺，需要对太阳能潜力有一个更完整的认识。本文估计了帕米尔地区和塔吉克斯坦南部太阳辐射的能量潜力。提出了定义帕米尔（Pamir）地区方位角最大值的数学模型。提供了通过考虑日光持续时间来评估两个系统的功能以及太阳辐射和能量势的增量的表达式。基于两种技术系统的使用，对月度，季节和年度太阳辐射水平进行了测量和计算。结果表明，双轴太阳跟踪器（DAST）的能源效率大大超过了静态太阳系（SSS）的效率，尤其是在秋季，春季和夏季。通过对双轴跟踪系统和固定系统使用太阳跟踪器，对太阳能生产和两个系统的效率进行了比较分析。结果表明，与SSS相比，DAST的年生产率平均提高了30％。在秋天，相对于固定安装的太阳能电池板，可移动系统可产生80％以上的能量。
