In the last two years, nearly 100 firms and NGOs have appeared on the scene to sell technologies including solar home systems, irrigation pumps, water heaters, street lights and their accessories and batteries.
The government has taken a policy to meet 5 percent of the country’s energy demand through green energy by 2015 and 10 percent by 2020.
In the last seven years, more than 10 lakh rural homes in off-grid areas have got lights through solar home systems (SHS), while millions still live without electricity.
“It is a big market. Only one crore homes have come under solar power,” said Md Akhtar Hamid Khan, chief operating officer of InGen Technology Ltd.
Some 80,000 SHSs are installed a month, said Choudhury of Allied Solar. Installation of SHSs will also require accessories such as battery and inverter.
Nearly half a dozen firms, including Rahimafrooz Renewable Energy and Electro Solar Power, stepped in to assemble panels.
The government had earlier set conditions that newly built buildings will have to meet a portion of their electricity requirements through solar energy in order to get fresh electricity connection.
The requirement for producing green energy is 3 percent and 7 percent of the total electricity demand in the residential and commercial buildings respectively.
Syed Istiaque Ahmed, head of sales of Rahimafrooz Renewable Energy, however, said many are assembling panels, targeting mainly the off-grid areas.
“There is a huge prospect of solar irrigation pump,” said the official.
Noting a recent rise in the installation of solar panels in the grid areas, he said a business opportunity has been created suddenly. But only 25 percent of the buyers are conscious about quality, he said.
Choudhury of Allied said his company works with around 20 realtors to set up solar panels in new buildings. “This segment of the market is also big.”
Choudhury also cited the potential of business of solar street lights, industrial water heaters, solar power plants and supplying solar power to the national grid.
“We have already won a government contract to install solar street lights from Notre Dame College gate to Kakrail Mosque,” he said.
