Quality Certification and Standards for Grid-connected Rooftop Solar PV Systems

Certification and standardization of PV system components is an on -going process in India. It is essential to the fast growth of the sector, since without product certification and standardization, there will be a lack of confidence in the technology and consequently, a higher risk perception among project debt financiers in the market.
