That is after 10 years NEM period if can't export. Already ROI on 5 or 6 years so consider free lah.

For TOU NEM, i did quick check if import equal export equal 620kwh, saving in TOU is less than RM1, so no urgency to register now as too much hassle

Maybe later TNB apps can 1 click subscribe then I will do so

not all string, must be hybrid string then only can hookup with DC coupling battery

normal string and micro need to use AC coupling battery

old bill lah, starting 1/7/25 all change

no need, just use AC coupling battery.

anyway string invertor and battery lifespan about 10 years also so time to change after the 10 years NEM period

if battery too expensive just use to charge my EV then

not so simple converting micro to string system as all the AC DC cabling all tak sama need to re-pull

As long export can match import the bill increment is minimal

By that time invertor and/or battery sudah rosak and need replacement

Don't just compare with previous month bill. Compare with your bill what if you didn't install solar at all.

RoI from 4 years to 5 years not the end of the world

That depends on the system cost and capacity

I don't see any significant changes in my own ROI, maybe like one month

For those haven't got NEM quota, can just forget about solar as selco not really worth it

For those already got NEM quota but not yet intsall, do your own ROI calculation. If the outcome still favorable just go install. No need to compared with the previous tariff what if no tariff revisions as that is reality no need to ponder so much

Old bill will deduct the higher tariff bracket first. New bill wouldn't. Any extra import will need to pay around 45sen per kwh. Then add sst add kwtbb then add 10 you are good to go

macam lah like GET insurance last time to lower import to less than 1500kwh

Where you get the idea of crazy new tariff? In facts it is just the offsetting mechanisms not as favorable to NEM users compared with last time.

Per kwh costs are actually lower for most domestic users

Yes. But one extra kwh is around 50sen regardless. Still much cheaper than charging outside or petrol consumption

I thought I explained to you before on the offsets mechanisms

Maybank Petronas ikhwan card, 8% rebate, weekend only

Still holding it but just pump petrol like 4 times last year just enough to cover sst

50/month

the only thing new is the RM10 peruncitan thingie

Other than that, is one to one offset

but last time is one lump sum rates like 52sen/kwh, now split to 3 that add up to about 44sen/kwh

last time NEM TNB offset at the higher tariff bracket first so most users will be charge based on 22sen/kwh etc based on lowest bracket for the net import

but now since is flat rates of 44sen/kwh, any net import will base on 44sen/kwh hence most users will experience big increase if their net import is a lot

so the new bill calculation is like 44sen/kwh x net import + RM10 + SST + KWBTT

although got EEI rebate now but most NEM users cannot enjoyed as most of the rebate will be deducted back

he is late for the cashback game, by the time he apply and get the shell card, probably TnC already tukar

surplus in previous months, can be used in coming months if generation not sufficient to cover for import

i did a quick check if got full EEI for NEM

Import 650kwh, Export 600kwh, will have negative bill RM10

Export less than import still got negative bill, too good to be true
