Kibidula Farm|Mafinga, Iringa – Tanzania’s Largest Solar Water Pumping Installation Thus Far (August 2018)

See our new video on the largest solar water pumping system in Tanzania!

Power Providers installed a 68 kW solar water pumping system near Mafinga, Iringa Region a few months ago. The solar water pumping system consists of 216 x 315Wp solar modules powering 2 x 30 kW Lorentz surface pumps and it is, to the best of our belief, the largest solar pumping system to be installed in Tanzania to date.

This system is designed to pump 1.5 million litres of water per day of water from a dam to a large holding reservoir 50 vertical meters away, from where gravity takes it to an avocado irrigation project.

Solar Power System – Hospital in Karatu Jan 2019 – March 2021 

System criteria

Power Providers engaged in a process of installation of a solar power system designed using SMA PV and battery inverters to provide three phase power. This power was distributed to a segregated load base identified as ‘critical loads’ such as those for the operating theater, neonatal unit, laboratory, IT system and maternity ward. The process is ongoing and further phase engagement could see the solar power supply extended in the future to meet other less critical loads such as water pumping, administration, air conditioning etc.

Technical data

Power Sources: Solar/Diesel Gen-set/Grid power

Solar Array: 26.5Kw roof mounted North oriented array

Battery Inverter: 3x SMA Sunny Island 8.0H (Configured for three phase AC output)

PV Inverter : Sunny Tripower 25000TL-20 3 Phase PV Inverter

Battery: Tess Volt Lithium Ion 365 AH @ 48V battery bank

Generator: Fully integrated and automated 110 kVa FG Wilson three phase generator

Nkasi, Rukwa| Solar Water Pump (March 2021)

A 4kw submersible centrifugal solar water pump has been installed by Power Providers Tanzania to our client at Lake Tanganyika for the purpose of pumping water from the lake Tanganyika to three fish ponds/dams near the area. The installed pump has the power to pump water for a distance of 500m from the water source to the reservoir and has a flow rate of 26 m3/h which is equal to 26000 liters per hour. The total array size of the whole system is 6.6 KW.

A Tented Camp, Iringa| Solar Water Pump & Power System (August 2020)

A 4kWp ground mounted Solar array powering a stand alone Solar Power System for a Tented Camp in Iringa Region. The system is 100% solar powered and powers all the important appliances needed by our client.


A battery bank with capacity of 400 Ah @C20, 48VDC system voltage and other components to support the installed solar power system.

Rhotia Valley, Karatu|Solar Power System (2019)

A 29.16 kWp roof mounted solar array charging a 144 kWh battery bank and providing three phase AC power using three Sunny Island SMA inverters (SI8.0H-12) and one Solar inverter Sunny Triple Power 25 kW PV inverter. The system was designed so that solar power provides most of the power to the property but was also hybridized with a generator so that in times of poor sun an alternative source of power is available so as to ensure power security. The system is supplying power to a lodge, orphanage home and a bakery at Rhotia Valley, Karatu


Emmanuel International| Solar Water Pump (March 2018)

The installed 5.5kW ground mounted solar array produces 83m3 of water a day (in the  least sunny month of January) from a balancing and sump tank to a final delivery tank over 4 kilometers away. From there, water is distributed to several distribution points in the village of Lumpembe Lwasenga and overflow from the tanks goes to nearby farms.  It is a magical feeling to flick the switch on the pump controller and to see so much water appearing so far away.
