A study on the photovoltaic water pumping system in a village at 30 km of Keita (Niger) to meet the water needs of the five hundred (500) persons gave the following summarized results. Figure 6. Photovoltaic water pumping station with a volumetric pump at Niger. a. Assessment of daily the water needs: Using the Standard […]

Sizing of the PV generator
Radiance*(1 – loss) As the system works all year round, the field is tilted at an angle equal to the latitude of 15 ° N. It was in August that the average number of hours of sunshine is the lowest maximum: 6.5 hours/day. Assuming a 25% loss due to the temperature and dust, the required […]
Determination of the month sizing
The sizing month will be the worst month, i. e., the month that the ratio between solar radiance and hydraulic energy required is minimal. In our case it is the month of August is the month of sizing. In august the average time is 6.5 hours/day.
Determining of the available solar energy
The method used is based on the determination of daily mean values of solar radiation available and hydropower necessary. 5.2. Determining of the inclination of the photovoltaic generator which can be placed The inclination в to the horizontal plane of the photovoltaic panels (PV) must be to maximize the relationship between solar radiation and hydropower […]
Assessment of daily water needs of the population
Determining the water needs of the consumption of a population depends mainly of its lifestyle, the environment and climatic conditions of each region. Drinking, cooking, washing and bathing are the main uses of water for human needs. Animals also need water for their survival. The water use is also essential in the field of agriculture. […]
Sizing a photovoltaic water pumping system
Photovoltaic water pump sizing is the determination of the power of the solar generator that will provide the desired amount of water (Alonzo, 2003). The photovoltaic water pump sizing consists of: • Assessment of daily water needs of the population to know the rate flow required; • calculation of hydropower helpful; • determining of the […]
Solar radiation at Niger
To design a photovoltaic water pumping system, we will need to quantify the available solar energy. Therefore, it is very important to know the solar radiation of the locality. Solar radiation (kW/m2) is the energy from the sun that reaches the earth. The earth receives a nearly constant of solar radiation at its outer atmosphere. […]
Photovoltaic system
To generate the necessary energy to the motor of the pump, solar photovoltaic panels are placed for converting solar energy into electrical energy (Fig.3). As the panels generate a direct current (DC), it is often used DC/AC converter to convert the direct current produced by the solar panels into alternative current (AC) if the motor […]
