What is a solar water pump?
Solar water pump systems are one of the areas where solar energy is used most productively and effectively. Since wells and other water sources are often far from towns, it is worth noting how important it is to use traditional energy sources or to run a petrol generator over very long cables. However, these methods involve expensive equipment, labour, maintenance and constantly rising fuel costs. Solar energy, on the other hand, delivers more economical and productive results in this area.
What do we need to know to install the system?
1. The city where the system will be installed
2. The depth from which water will be drawn and, if possible, information about slopes, rises and tank height
3. If water is to be piped, the distance between the well and the site
4. The amount of water needed per day (tons, m3 or liters). This information is essential and directly affects the price of the system.
5. How many hours a day and how many days a week should the pump run?
6. What is the maximum distance the water must travel from the well?
7. Is there a difference in height between the well and the place where the water is delivered?
8. Is there a tank, reservoir or storage? If so, at what height?
9. If drip irrigation is used, how much pressure is needed?
10. In which season is water demand highest?
Where are solar water pumps needed?
Solar irrigation systems are the most suitable way to meet the electricity needs of irrigated land far from power lines.
An irrigation system is one of the most important factors in areas that need continuous irrigation. Without adequate irrigation, the harvest can be lost entirely and even lead to extra costs.
Irrigation is generally done by drilling down to underground water sources. Irrigation pumps placed in the well draw water from underground or from the well and deliver it to irrigation channels. For watering farmland, two kinds of solar systems can be installed: connecting existing AC pumps to an off-grid system, or installing DC pumps that do not need batteries or an inverter. Which system will be more productive is determined by engineers after precise calculations.
Equipment used in solar-powered farming systems
1. Solar water pump
When installing the system, the most important thing is to work with licensed and experienced companies, choose a solar water pump that matches your needs and calculate the system correctly. Thanks to the specially manufactured solar water pumps used in the system, the energy the system needs will drop several times over, making it possible to use lower-power solar panels and make the system more affordable. In addition, because no inverter, charge controller or battery is used, energy is consumed where it is produced, so the system runs with high efficiency.
2. Solar panels
Since solar panels are the energy-producing part of the system, they must be installed correctly and professionally. When sizing and installing the panels, the hours during which the system will be used most should be taken into account. For example, if irrigation will only be done in summer, the panel orientation should be adjusted accordingly, because in summer the sun's rays arrive at a steeper angle. If the system will be used all 12 months, the values for the shortest day of the year (21 December) should be calculated and the system simulated based on the solar radiation of that day. The biggest mistake made during installation is often in panel selection. Choosing the wrong panel size will cause the system to stop working in winter.
3. Sensors
Well sensor
Used to measure water levels in the well.
Pool sensor
Controls the motor according to the water level in the pool.
4. Mounting equipment and cables
The structures that will hold the panels and the cables must be determined through the necessary calculations to suit the installation site.
Apart from this equipment, devices such as a DC breaker or Powerpack may be used depending on the pump model and system design.
Advantages of solar water pump systems
– No connection to the grid
– Only the initial investment cost
– Running costs are zero (except for maintenance and service when needed)
– High efficiency
– Low energy losses
– Easy to install
