ABSTRACT:

本文讨论了太阳能水泵系统的性能；该系统由光伏（PV）阵列，永久磁铁（PM）DC电动机和螺旋转子泵组成。使用PSPICE分析PV阵列的操作。通过最大功率点跟踪器（MPPT）和一个太阳轨道。提出了仿真和现场测试结果。

USE OF SOLAR ENERGY:

Solar energy can be utilized in two ways:

Solar Thermal (ST) technologies where the heat produced are used to operate devices for heating, cooling, drying, water purification and power generation. The devices suitable for use by village communities include solar hot water heaters, solar cookers and solar driers.

Solar Photovoltaic (SPV) systems which convert sunlight into electricity for use applications such as lighting, pumping, communication and refrigeration.

The Solar Energy Programme is prominent among the technology-based renewable energy programmes of the MNES. Areas covered under this programme include solar thermal technology (hot water systems, cookers, dryers, solar passive architecture etc.), solar photovoltaic technology (lanterns, fixed systems, pumpsets) as well as information dissemination, marketing, standardisation of products and R&D. The support to the programme is mainly in the form of subsidies and technical support.

SOLAR ENERGY FORAGRICULTURE

对电能的需求远远超过了供应，尤其是在农业领域，并且在需求中满足这种指数增长的农业生产率与直接和间接的能源输入和政策越来越困难，以巩固这种关系与这种关系与建立关系。农民的好处。如果要实现农村发展，则必须提供能源投入，这可能需要整个国家的特殊努力，以开发和利用可再生能源最重要的是太阳能，而不是其潜力窃听潜力。农村电气化已经避开了国家最遥远的农村地区。

SOLAR CELL

太阳能电池是基于光伏效应的原理 - 通过从入射太阳辐射中吸收能量的材料中的电荷载体。太阳能电池在将入射太阳能转换为电能方面的效率取决于照明频谱强度，电池的结构和设计材料，大气温度和dustiness of the sky. Solar cell used in running DC electric motors have efficiencies ranging from 10 to 12 percent.
硅是制造太阳能电池的最常用材料。其他材料包括硫化镉和砷酸盐。太阳能电池的制造涉及大量过程。晶圆形式，然后是连接形成，接触式制造和抗反射涂层在细胞的活动表面上。面板的外表面受到特殊钢化玻璃的保护，该玻璃可提供高阳光的透射率。

太阳能泵单元基本上由太阳能阵列，直流电动机和泵单元组成。其他组件是电气控制和某种用于跟踪太阳阵列的机制。许多类型的抽水集用于光伏系统，垂直centrifugal pump coupled to a submersible DC electric motor or an ordinary volute centrifugal pump close-coupled to a horizontal DC electric motor.

However, the submersible pump unit is more suitable for the photovoltaic system. The arrangement eliminates the suction pipe and foot valve and results in a higher efficiency of the pumping unit. The submersible pump is made leakproof by a silicon carbide mechanical seal. In case of volute pump, care is taken to limit the pump suction within about 5m to maintain a high level of pump efficiency.太阳阵列的输出随传入辐射的强度和其他因素而变化。因此，有必要将可变速度直流电动机与面板输出匹配。至少一种光伏动力泵组的成品利用最大功率控制单元作为系统的组成部分，以使泵上的负载与面板的不同功率输出相匹配。

ADVANTAGES OF SPV PUMPING SYSTEM

Cost effective:

与常规系统相比，生命周期和最终造成的最终造成的成本使SPV系统的成本效益。此外，农民还可以从他的资本投资中拯救出他为从网格到他的田地/农场的绘图线所做的资本投资。可以节省巨大的资源，否则这些资源可能是不经济的，无法在州电网下建立每个农业领域。

Reliable:

与农村地区的常规电力系统相比，SPV更可靠，一致和可预测的功率选择。

Free fuel:

Sunlight, the fuel source of SPV system is a widely available, inexhaustible, and reliable and free energy source.Hence the SPV system has no monthly fuel bills.

Low maintenance:

The system operates on little servicing and no refueling, making them popular for remote rural areas, hence the operation and maintenance is very low. The suppliers provide maintenance at a very low annual maintenance contract rates.

Local generation of power:

SPV系统利用本地ResourcesUnlight。这提供了更大的能源安全和控制能源的控制。

Easy transportation:

As SPV systems are modular in nature they can easily be transported in pieces/components and are easily expandable to enhance the capacity

节能减排：

太阳能显然是最有效的节能计划之一，并为农村地区的分散光伏发电提供了一种手段。decentralized system avoids any unnecessary expenditure on T & D networks

节约用水：

The SPV sets are highly economical when combined with water conservation techniques such as drip irrigation & night time distribution of (day time pumped & stored) water. The SPV system leads to optimum exploitation of scarce ground water.
