Speakers at a virtual talk on Saturday called on the government to tap into the potentials of rooftop solar electricity to relieve people of their burden of rising expenditure on electricity.

They said that Bangladesh had achieved very little in pursuing its goal to source 10 per cent of electricity from renewable energy sources by 2020 with only 2.93 per cent electricity currently generated from renewable sources.

Of the 649.72 megawatts generated through renewable energy, Bangladesh produced 230 MW using hydro power and 420 MW using solar power, said the speakers.

‘I suggest you not to be hooked on number,’ prime minister’s energy adviser Tawfiq-e-Elahi Chowdhury said at the talk defending the government’s position on renewable energy sources.

He said that 10 per cent of the country’s population was now connected to the home solar system and that was an achievement to claim credit for.

He said that solar electricity was still unreliable because of its unavailability after nightfall.

He called for becoming more creative and increasing focus on solar storage so that an uninterrupted electricity supply could be ensured using solar energy.

The virtual talk was organised by Energy and Power Magazine.

Infrastructure Development Company Limited’s Renewable Energy Division head Enamul Karim Pavel said that per unit expenditure for power could be reduced to Tk 5 from the existing Tk 7.7 by tapping into the potentials of solar energy.

He said that the solar energy technology was cheaper and the production cost of per unit of electricity from the source would drop to Tk 4 by 2025.

An estimated 400 MW could be generated using 420 lakh square feet of roof tops in textile factories, said Pavel.

Speakers said that the idea of rooftop solar electricity suffered a setback after the home rooftop solar system failed to yield the expected results because of substandard equipment imported without any standardisation.

The talk was also attended by Dhaka University’s Institute of Energy director Saiful Huque, Sustainable and Renewable Energy Development Authority chairman Mohammad Alauddin, IDCOL deputy chief eexecutive officer Monirul Islam, East Coast Group managing director Tanjil Chowdhury and GIZ’s renewable energy and energy efficiency programme coordinator Al Mudabbir Bin Anam, among others.
