MNRE document outlines some overall PV System requirements
MNRE (Indian govt ministry) testing has been done at the Central Power Research Institute (CPRI) for Selco systems. The individual components are also separately tested and certified by the manufacturers. Interview with representative
Improper knowledge of operation of charge controller could lead to damage or electrical fires. Possibility of exposure to battery acid if maintenance is not conducted properly.
Majority of research focuses on the financing and business model SELCO uses to distribute its product, or is a general review of the home solar system market landscape in India. No research found regarding system performance.
