For tribals of Khamkheda, a small hamlet near the Bargi Dam, the Sunday night was a different experience as their houses lit up by solar powered lamps.
The village is around 7-8 km from the Bargi Dam, on the banks of river Narmada, and has no electricity supply from the government.
The tribals said their village finds place in the list of villages that would submerge under the dam waters and thus they were denied the power supply by the government.
Thirty families reside in the village would never forget the contribution of a freelance photographer and writer Rajnikant Yadav of Jabalpur, who with financial assistance from one of the founder members of HCL Padma Bhushan Ajai Chowdhry, installed solar power lamps in their houses, free of cost. Three solar power lamps have been provided to each house and three streetlights are installed in the village.
Before introducing solar power lamps to tribals, Yadav surveyed entire market for the availability of various kinds of solar powered lamps. "The lamps in the market were costly and it would not have solved the purpose since the tribals have meager earning sources," Yadav said.
Thus he started working on developing a cost-effective lamp for couple of months and got success by devising completely new electrical circuit and finally the lamp.
Yadav said after research the cost of installation of three lamps costed him Rs 7,000 per house, this includes market survey cost, expenses on articles like solar panels and battery etc. However, Yadav says the cost would go down by almost half as there was no need for research or survey in future.
One villager has been trained to repair the wiring and a cycle is provided to charge the battery with 6-7 hours backup during monsoon.
When asked if any person wants to approach him for the know how of the lamps developed by him, Yadav said he would provide the knowledge free of cost.
