What advancements have been made in solar technology that are specifically relevant to India’s climate and geography?

The major advancement in technology is the progression on more efficient solar modules. Earlier India saw polycrystalline modules which had lesser efficiencies. Later major solar module makers started making mono-PERC technology based solar modules which could offer effiiencies of around 21%. Now the country is slowly moving to TOPCon technology which offers efficiencies higher than mono-PERC. Another advancement had been was in bringing more Wp panels. Now India has panels having a maximum Wp power of upto 680Wp. Higher Wp power means that to generate the same amount of solar power we would need lesser number of panels as a single higher power panel can produce enough power.
