Dude this is NEM - COmes with warranty - maintenance is to wash wipe solar may be everyyear depending on your location- not like car.

solar panels got warranty till 25 years.

Controller 5- 10 years.

installation usually 3 years.

so wait what? till TNB price go up? then think abt solar?

Exactly - very good deal , will get better in time when tnb prices goes up government already has plan to remove 10B subsidy slowly starting next week.

Tell your brother prepare 50k soon - After they change smart meter --- they will cross reference check historical usage and current - then 200% kena fine.


With smart meter possible to stikk hack but 100% kena tangkap because they will monitor the grid total usage not the meter only total usage.



Good luck . lol!

Speaking from friends experience recently.

Remember your sheet shows after 10 years you cant sell back because nem contract is over (not sure if government will continue or extend confirm have to reapply).


Take note - ppl who did their homework abt NEM soalr already know after 10 years they buy batteries and store access energy for night use. This will also consider as saving already but upfront cost would be battery .

Currently estimate price for 5kwh = RM5k-6k (can get cheaper , battery and solar prices keeps dropping).

Average we need at least 10kwh per house depending on lood/usage.
