For the last ten years, a Su-Kam team has been working quietly in one of the most under-developed regions of the world – Malawi. Their mission is simple – to bring the boon of electricity to the inhabitants of five remote villages: Chigundu, Mdayaka, Eluyumi, Kumbande and Kadzuwa.
The team first observed and analyzed the conditions in the villages. The wind speeds in these villages were around 5 meters per second, adequate enough to generate electricity. Sunshine was also in abundance. Accordingly, the Su-Kam team decided to set up a hybrid system using a combination of solar and wind energy. The usage of windmills succeeded in bringing down not only the cost of the project but also in reducing the space requirements for the installations.
In each village, Su-Kam installed 3 wind generators of 4.2 kW each, along with solar photovoltaic modules of 24 V / 150 W, generating 7.5 kW. The systems today generate 20.1 kW for around 150 households in each village.
This unique hybrid system was designed and customized by Su-Kam's in-house R&D team, keeping in mind the objective of maximizing the use of natural resources like wind and the sun, and at the same time not losing sight of the objective to make the systems economical, reliable, long lasting and perhaps most importantly, environment friendly.
Till date, all the systems are fully operational and have been working successfully.
