SUNFLO Solar Pumping Systems

Solar pumping has become a popular and ideal solution for various water supply applications, with AC motor pumps widely used in combination with DC/AC inverters to enable hybrid PV solar/AC mains supply operation. The Dayliff DSD range of borehole pumps, when combined with high-specification Dayliff Sunverter controllers, offers efficient and cost-effective applications of this technology. Here are some applications where the Dayliff DSD solar-powered borehole pumps can be utilized:

1. Agricultural Irrigation: The DSD solar-powered borehole pumps are well-suited for agricultural irrigation systems. They can efficiently lift water from boreholes or wells and distribute it to crops, ensuring optimal water supply for irrigation needs.

2. Community Water Supply: These pumps can be used to provide water supply for rural communities or remote areas. By harnessing solar energy, they can pump water from boreholes or wells to storage tanks or distribution points, ensuring access to clean water for community use.

3. Livestock Watering: Solar-powered borehole pumps are applicable for livestock watering in farming or pastoral applications. They can reliably provide water for livestock in remote locations or areas without access to grid power, supporting the welfare and hydration needs of animals.

4. Domestic Water Supply: The DSD pumps can be used for domestic water supply in off-grid or remote residential settings. They can lift water from boreholes or wells to storage tanks or directly to households, providing a sustainable and independent water supply solution.

5. Water Conservation Projects: Solar-powered borehole pumps are suitable for water conservation projects, such as rainwater harvesting or groundwater management initiatives. They can extract water from boreholes or wells for storage or recharge purposes, contributing to sustainable water resource management.

6. Pond and Lake Aeration: These pumps can be utilized for pond and lake aeration, promoting water circulation and oxygenation. They can help maintain water quality, prevent stagnation, and support aquatic life in recreational ponds, fisheries, or natural water bodies.

7. Emergency Water Supply: Solar-powered borehole pumps can serve as a reliable emergency water supply during power outages or in disaster-stricken areas. They can provide immediate access to water from boreholes or wells, supporting relief efforts and ensuring essential water needs are met.

8. Remote Monitoring Stations: These pumps can be used in remote monitoring stations or environmental monitoring sites that require water supply. They can pump water for various applications, such as scientific research, data collection, or environmental measurements.

These applications demonstrate the versatility and effectiveness of the Dayliff DSD solar-powered borehole pumps in a range of water supply scenarios. Combined with high-specification Dayliff Sunverter controllers, they offer efficient and cost-effective solutions for utilizing solar energy in water pumping applications, reducing reliance on conventional power sources and promoting sustainability.

MOTOR
The pump is fitted with of permanent magnet type totally enclosed brushless motor with 24V DC power input from either a direct source or photovoltaic modules. Internal thermal protection is also provided.

PUMP OUTPUTS
Performance curves are given at standard test conditions of 1000W/m2 solar irradiance and 250C. Output will vary throughout the year depending upon prevailing irradiation levels. For estimated daily outputs at continuous pumping multiply the indicated output at the duty point by the daily irradiation given in Graph 1. For indicative purposes factors of 1.1 can be applied for hot arid areas and 0.9 for temperate high altitude areas in the Tropics. Output will vary throughout the day as a proportion of the estimated hourly irradiation as shown in Graph 2.
