India's Solar Indigenisation on Track for Full Value Chain in 5-6 Years: ReNew CEO
India wants to make all the parts needed to build solar panels right here at home, like special materials called wafers and polysilicon.
The CEO of a big solar company, ReNew, thinks this will take about 5 to 6 years.
He also believes India can reach its goal of having 500 gigawatts of clean energy by 2030.
This is a lot of energy, enough to power many homes!
Sometimes, many new solar projects are ready, but there aren't enough buyers for the electricity they will make, or the power lines aren't ready to carry the electricity.
ReNew is also thinking about making green fuel and wants to build more solar panel parts themselves.
They see a lot of solar panels being made in India, but some smaller companies might have trouble because there might be too many panels already.
The CEO is optimistic about India's clean energy future, especially with storage like batteries helping to use solar power even when the sun isn't shining.
ReNew CEO Sumant Sinha estimates full indigenisation of India's solar value chain within 5-6 years, with wafers potentially being domestic by 2030.
India's 500 GW renewable energy capacity target by 2030 is considered achievable, with factors like rooftop solar and other schemes contributing.
A surge in auctioned renewable energy capacity has led to over 40 GW of projects struggling to secure power purchase agreements due to DISCOMs' limited absorption capacity and transmission constraints.
ReNew Energy is exploring backward integration into the wafer and ingot segments and expanding into the green fuel sector.
Excess capacity in solar module manufacturing in India is a concern, potentially challenging smaller players, while ReNew is expanding its cell line capacity.
