solar panel in Malaysia cannot ROI.
by the time you ROI your money , your battery and panel will require replacement.


Your total investment is RM47,000
if each monthy you save Rm1,000, that is 47 months .. close to 4 years but your battery will degrade over time and solar panel efficiency is also reduced, you won't be saivng Rm1000 each month.


According to friends in Japan who frequently have earthquakes , they do suffer frequent power shutdown. Their solar panel is for emergency . not to save money.

install solar but no battery ? then install solar for sunny day use ?
