Water by solar power and battery storage on Bear Sheba

ProfiNRG dreams of 24-7 water on Bear Sheba, will you help?

ProfiNRG's 10th anniversary coincides with the 10th anniversary of the Beer Sheba project in Senegal. For us, reason to put an extra spotlight on this project. Partly for this reason, our marketing & communications colleagues went to Senegal to visit the projects where, among other things, our used/residual solar panels and inverters go.

On Bear Sheba, Anco van Bergeijk and Ewien van Bergeijk started 10 years ago with a few panels and a well. This has since grown into a 100-acre project with a farm (chickens, pigs, goats and cows) training centre for young Senegalese farmers, school, clinic, church, store and vegetable garden. This provides employment for many people, including some with disabilities.

'We visited the Bear Sheba Project there, says Jolien van Hattem. It is great to see all that has been accomplished there in the last 10 years through solar energy. With the energy generated, 300 m3 of groundwater per day is pumped from about 70 metres deep, which can be used back on the land, for animal care and for the community in their daily lives. There is also a tapping point for the residents of the surrounding villages; we saw the donkey carts full of jerry cans driving back and forth here.

'With sufficient water pressure and electricity, they can irrigate about 500 m2 at a time with an already existing sprinkler system, Corina Nsengimana said. 'The machine rotates slowly, spraying this huge area in a matter of hours. Unfortunately, it cannot be used to date because the power supply is insufficient for both the water pump (due to the required water pressure) and the sprinkler system itself.'

Bert van Woudenberg: 'At the moment there is just enough solar energy to run the general water pump from 7 am to 7 pm. It seems ProfiNRG would be nice to donate 500 kWh of batteries for this (+/- € 25,000,-) then enough energy can be stored for the general power supply and to run the sprinkler system at night, which is of course much more productive than during the day in the burning sun. This is obviously not a new battery, but consists of recycled lithium batteries from the automotive industry, a specialty of Anco.'
