The scientists of Bangladesh Council of Scientific and Industrial Research (BCSIR) have discovered that solar panel can run without the support of battery.
In the traditional solar penal, battery is required as per its capacity. But the BCSIR scientists revealed that it can run without the support of battery. As a result, the cost of installation of solar energy system will be reduced by around 75 per cent, sources said.
In the meantime, the scientists have recently installed 64 kilowatt capacity solar power plant on the BCSIR campus and added it with internal power grid in June this year. They are now more confident, particularly after the test of the solar power generation without battery.
The per unit power cost will be within Tk 7.37 while the traditional solar power cost of per unit is around Tk 30 to 35.
The project on solar power without battery, started in 2012 on experiment basis, was completed in June at a cost of Tk 27.77 crore, said Shahriar Bashar, a senior scientist of BCSIR and the project director.
He said, life time of a solar power system is around 25 years. During the time, the battery needed to change 10 to 12 times for better service that is very costly. Solar power without battery will be in affordable price as it is once installed no need to change.
The BCSIR scientists discovered thin film solar cell as alternative of costly battery and they became successful. The life time of the thin film
will be similar of the solar panel, Shahriar Bashar said.
The solar panel can be popular commercially as it is possible to provide in available affordable price. Besides, the country can save 10 lakh tonnes diesel annually if the solar panel could be installed for irrigation pumps, he said.
Power Division sources said, around 30,000 solar panels are being installed in different households across the country.
At present the country is generating 175 MW solar power. Currently, 213 irrigation pumps are being run by using solar power out of a total of 45 lakh pumps.
The government has a plan of generating 10 per cent of the total electricity from solar by 2020.
