As long your bill can hit above RM200, then worth to install, small size package, can try check with ERS for free quotation. Their smallest package for 5kwp think only cost 14k, due to government now give RM4k subsidy. U can use public bank credit card, the charges is only 2% if you convert to 60 mths repayment. Better than 3.92kwp which is too small

My house is strata landed, so the trunking pipe at the back yard wall have to be concealed, can't fix it on the wall surface

Ya, the installation company's technician said no issue. But of course if next time if the cable got issues, need to hack the wall to replace. I got no choice because management insist me to conceal the trunking pipe

Inside the house, my cable all hide in the plaster ceiling, all the way to store room, then only mount on wall surface in the storeroom cover with metal casing.

They more concern on the door of storeroom, must have ventilation hole. So the inverter and another device won't be overheating.

My own contractor hack the outside wall, and leave all hole on plaster ceiling follow installation plan, then solar installation team come to fix wire with trunking, then my contractor conceal and repaint it back. The installation team quote 3000 for conceal, my contractor only charge 1200, he charge cheaper as he was renovating my whole house that time.

How did your installation company advise? My installer said the inverter can not be placed too far from DB box because power will loss during transmission, the longer the distance, the lesser the power receive by DB from your inverter.

Can not open ventilation hole on your cabinet?

They didn't explain on how to calculate it, but even increase 1 meter of distance so that my inverter can be fixed on another panel of wall, they already complained. As they need to ensure the units of power received in DB is closest to their estimated output. Plus the system itself will also consume some energy too, so if you loss more energy due to transmission plus the energy consumed by system itself, your net kWh received will be very low.

Not sure about the structure of your house. Maybe you can engage another solar company to come and do site inspection since it is free, see what is their installation proposal, so you can compare both's opinion. My time I also ask two solar companies to come and do inspection then compare their outcome.

I can only say my technician is very demanding, as he thinks should minimise the distance so can draw maximum power from inverter for system to consume. But anyway he still have follow my request as I am the one paying.

I agreed with him as there will still be losses so the shorter the better. My TNB meter and DB is already more than 30 meters, which can't be changed.

just wondering, why your inverter got sound and how many kwp for your solar?

Hope I still remember correctly, your inverter should have wireless access to your home WiFi, so you can check with your phone on total output. So on day time, your inverter will receive power from the board, usually in the morning to noon, so at this moment all converted current will be consumed by electrical appliances, including the board itself. If there is excess power, then it will be delivered to TNB grid and your TNB meter will record the unit. Otherwise, if the DB does not have enough power from inverter, it will draw power from TNB grid so your meter will record the unit. At night time, your DB will draw all power from TNB grid only. So when come to month end, you need to compare the total amt of units generated on your solar app, against the net units consumed on your bill.

Let say your app show 1000kwh generated, yet ob TNB bill "tenaga dijanakan" only 800, which means in that month your DB only consume 800, and offset by your generated units. But the difference of 200+ means you should have extra of 200kwh produced and to be kept in your NEM Baki account, YET usually the increase in your NEM Baki will be lesser, let say only 100, the another 100 went missing is the power being used by the solar system itself, and loss during transmission.

I don't think that is reliable. And why keep in store room because my 2.5hp air con open full time during day time, so with proper ventilation, my storeroom always stays cool enough.

So don't see why need to install at outdoor

U don't use air con then U spent 20-30 k install solar for what purpose? Lol

And those house that you can see with inverter install at outdoor is because they are old houses with single phase, which the DB is at the front part of the house.

And got sound and noise some more, which really makes me surprised.


Btw, saw your post in 2019 shared by others, so your one is NEM 1? Now receive cash pay by TNB?

That is why, instead of promoting power consumption saving habits, and encourage ppl to go for green energy, they reverse the trend by sacrificing solar users benefit, and let those non solar users to enjoy lower tariff. Just because b40 can't afford solar.

Now installing solar seen like become waterfish already, lol.

My bill also become double this mth. Speechless, we paid to invest in green energy, end up have to pay more for the bill

Ya, better avoid solar since now roi no worth, the whole solar industry think will be suffered, unless for commercial and industrial users.

I already spent, can't do anything except from becoming a frog being slowly cooked in water😅

Never thought a contract also can be changed easily.

Those who want to install, better take in the risk if gov want to manipulate you, now extend your roi 1-2 years extra by changing tariff, next time dont know how many years more.

With previous tariff, yes definitely worth.

Now with new tariff, unless installers can reduce the solar cost, if not don't see the point to install

Inverter usually last for only 10 years times, Huawei or other better brand maybe can last longer, but it also come with cost.
