By eliminating the need for traditional diesel and electric generators, this project greatly reduces carbon emissions and promotes a more sustainable future. The Solar Water Pump Inverter is scalable and designed to be user-friendly and low-maintenance, making it an ideal solution for businesses and individuals alike.
Overall, the Solar Water Pump Inverter is a clean and reliable solution for water pumping systems. By harnessing the power of the sun, this technology promotes a greener future and contributes to the fight against climate change.
Solar Pump Inverters Enable Sustainable Irrigation in Rural Communities
Rural communities often face challenges with traditional water pumping systems, which can be expensive, unreliable and harmful to the environment. This led to the implementation of solar water pumps with Solar Pump Inverter in many regions around the world to overcome these challenges.
In the Mount Kenya region, farmers previously used petrol and electric water pumps for irrigation. However, the Solar Pump Inverter provides clean and reliable water sources, improving irrigation coverage and increasing crop yields while reducing environmental impact. With the scalability, low-maintenance design, and cost savings of this technology, rural communities worldwide can achieve greater sustainability. The Solar Pump Inverter is making a positive impact on farmers’ lives globally.

Energy saving and application
1. Technics effect after reconstruction
- Compare economy index of October 2002 and October 2003. Average load is 12.8MWOctober 2002: average vacuum: 90.26%, primary water flow: 5000t/hOctober 2003: average vacuum: 93.37%, primary water flow: 3500t/h
- Calculation of a monthOctober 2002: cost of primary water: 5000×24×31×0.4=1488000yuanOctober 2003: cost of primary water: 3500×24×31×0.4=1041600yuanCost saved: 446400yuan(USD 65647)
- Vacuum of October 2002: 90.26%, corresponding air discharge temperature: 42℃Vacuum of October 2003: 93.37%, corresponding air discharge temperature: 35℃From comparison, air discharge temperature lowered 7℃. When vacuum heightened 1%, there was coal consumption 3.5g/kW•h saved. So compared with vacuum of October 2002, vacuum heightened 3.11% in October 2003. Coal consumption 10.9g/kW.h was saved. Power generating is 94950000kW.h in the month, coal saved: 94950000×10.9×0.8=827.96t×210yuan/t =173900yuan (USD25573)
- After using frequency inverter, monthly power consumption is just 130000kW.h more than mode of single pump work in direct on line. Cost: 130000×0.196=25500yuan (USD3750)
- So monthly economy benefit: 446400+173900-25500=594800yuan, yearly economy benefit: 59.48×12=7137600yuan (USD 1049647)
2. Advantages of frequency inverter during application
- Frequency inverter reconstruction reduces times of pump start/stop, keeps system reliable, lowers adjustment difficulty.
- Frequency inverter improves adjustment flexibility. It is convenient for cleaning glue ball of condenser. Originally, this work demanded primary water. During the course, increasing/decreasing primary water, starting/stopping circulating pump lead to circulating water waste. Variable frequency pump meets water level demand by adjusting motor frequency.
- In summer, starting variable frequency pump can increase inlet water, heighten cooling efficiency of tower, which avoids flooding, increases circulating rate of cooling water, lowers air discharge temperature, improves thermal economic.
- In winter, when water temperature is low, just starting one variable frequency pump can ensure reliable temperature of air discharge, heighten system safety, decrease primary water and power consumption, which lowers cost and enhances benefit.
3. Comprehensive benefit
- Frequency inverter has been running stably since it put into service in September, 2003. Controllability of circulating system heightens greatly. Frequency inverter not only saves much power but also lowers primary water, reduces times of pump start/stop. It also improves vacuum, decreases coal consumption.
Thereby, this project got second prize of science & technology achievement and first prize of Power Plant science & technology development.
