We designed, supplied and installed a roof mounted solar array (total 530Wp) and a submersible solar water pump with accessories.
The SWP system will provide a minimum average of 3,000 liters per day to the ranger camp during the least sunny conditions – sized for the month of June.
A 530Wp solar array
A 5.5 kW roof mounted solar array charging a 28.8 kWhr battery bank and providing three phase AC power using three inverters. The system was designed so that solar power provides most of the power to the property but was also hybridized with both Tanesco and a generator so that in times of poor sun an alternative source of power is available so as to ensure power security.
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.
