Coming Soon: 
An off-grid high school is providing safe water for 600 students off the coast of Bangladesh with the help of ENFusion™ Cell 2000.
During a drinking water crisis in the District Bhola of Bangladesh, the Ramaganji school with 600 students had no access to a power grid, and were expected to use diesel generators, and the high operating cost of generators was beyond what they could afford.
Not only did students lack drinking water, but they also lacked water for the use of toilets and sinks. Students had to struggle with a hand pump to get water for their privy use. A better solution had to be found.
While looking for an answer, the school already had the primary tool needed to pump water, but not the means to provide it with electricity. After careful consideration, Bestway Powertech Ltd., a Bangladesh-based company working in renewable energies, opted to deploy a system utilizing ENFusion Cell 2000 controllers — the only controller they found allowing them to configure 50% fewer PV (Photovoltaic) panels to power their 2HP pump in their design.
In addition to saving money in panels, this design also generated savings associated in other costs, such as racking, cabling, setting the PV array itself, and represented a far simpler system design. Rather than having to specify and integrate different devices, controllers, inverters, and boost systems, ENFusion Cell 2000 was able to deliver all of the same functionality in one compact, inexpensive, and fully integrated device.
Since the ENFusion Cell 2000 also works with any pump, regardless of voltage, phase, and frequency, Bestway Powertech Ltd. felt confident that they would be able to replace the pumps at the end of their useful life without having to redesign the associated power electronics.
The solar array of 16 panels uses 10 panels for lighting, and 6 more are used for providing water. The pump runs for 6 hours each day, starting at 9 a.m., and lifts an estimated 14000 liters of water in a single day.
As the shortage of fuel has hindered electricity demands in Bangladesh, using solar power generation plays a vital role in diversifying energy sources in the country. The solar water pump project will help as a capacity building tool for diversification of solar PV technology in remote rural areas of Bangladesh, and it will bring new technology into workplaces in the future that can expand into remote irrigation systems and agricultural needs.
This will result in an estimated savings of 900,000 tons of diesel if only half of the 1.3 million diesel-run irrigation pumps are replaced by solar, which would also lead to an enormous impact in CO2 output reduction. The savings of using Solar PV Modules, was estimated to be roughly $1,000 over the course of 3 years.
Solar panels that utilize daily energy to generate electricity can provide clean water, lighting, and more to the people of Bangladesh. This can improve everyday life tremendously while incurring an almost-zero operational cost.
Water is an essential substance, and the ENFusion Cell 2000 makes accessing it easier, and more convenient.
It is estimated that over the course of its lifespan, nearly 11,000 students will benefit from the project.
