Actually i still tak faham what's the other way of calculation that give us more advantage? I remember there was a tered that said TNB screwed us over with the way they calculate that tip the scale on their favor.

RM 4000 for Sinopoly 48V 200aH (Shouldn't buy from shady supplier, my great mistake)
RM 12000 for upcoming EVE and Batterotech 280Ah
RM 8000 for 4200watts solar panels, technically the total is 5340watts solar panel after I added 4 more panels, but I only able to reach average 4200-4800 watts for most of time at noon (Work very well)
RM 3600 for Growatt SPF 6000 ES PLUS (Off grid model) (Perfection in every way?)

Burned RM3000 for Growatt MIN 4200 TL-X (Grid tie model) (Work great with zero export, not suitable for my usage unless if I can get into net metering)

Not sure about the other misc stuff such as torque wrench, nut, bolts, railing, breakers,wiring, BMS (JK-BMS), active balancer etc. Around RM3000?

SEB and SEDA = don't even waste your time. I tried, and they really not interested to do net metering at all. Requirement = NEM contractor. Minta list kontraktor, "pergi cari sendiri, sini takde list contractor NEM" 

Half-cut solar panels 445W monocrystaline x 12 pieces bought back in year 2020.

Ever try to order solar panels to sarawak (the wooden packaging crate and foam etc) and paying all those custom duty?   
Tell me if the price is worth it or not.

hence why kontactor nem can markup alot n make money..
people here havent gone into "build your own PC" mode in evaluating cost of solar components.

not really, u can see in the DIY solar FB group.. damn the name is DIY, but 8 out ten is asking for contractor to supply and install how much?

aha, so we're not bound by the max 10kWp stated by government? LOL. Would it be illegal to install more?

Can you share the price with us?

Not much sense to go for microinverters imo, harder to repair and probably harder to troubleshoot since they are located on your roofs.

EMIT SOLAR also using inverters with AFCI built-in based on the following datasheet.

While, this is their panel.

Any comment about EMIT based on their products above?

Oh, its provided by them, don't think we can choose which model of panel we want.

i thinking should i go for solar,
currently usage rm150 to 180.

with control aircon usage, the weather is getting more and more terrible, so thinking need to on aircon more.

NEM system cannot install battery? what about after 10 years when the contract expire?

Can install. But what is the benefit? You don’t want to draw so much from tnb grid to make sure you’re below monthly 1,500kW threshold? There’s a 10 cents surcharge per kWh if you exceed 1,500kW drawn from the grid. It applies even if you’re on NEM.

But even assuming the surcharge applies, 1501kW * RM0.10 = RM150.10. Per annum it’s RM1801.20. Current battery system costs way more than that.

There’s no clear ROI? Unless you’re consuming way more — but that also means you need a large battery and a huge solar system.

Huawei’s inverter is battery ready. Hopefully 10 years later the NEM gets renewed or the battery costs comes down. Yes yes Huawei supports proprietary batteries only and it’s HV battery. But you can still do AC coupled battery with inverter with the Huawei system. Same same.

Tak faham. Whats the benefit?

get the certificate for what? why would i want to pay extra?

Dear all solar sifu here, need your advice.

My house has single-phase power with an average TNB bill of RM300+ per month. Currently, I have received 3 solar system proposals as summarised below:

1. JA panel 590Wp (N-type panel) + Solis 1P5k inverter - system size 6.49kWp (11 panels) - RM 20k

2. Longi panel 580Wp (P-type panel) + Solis 1P5k inverter - system size 6.38kWp (11 panels) - RM21k 

3. Trina panel 600w (N-type panel) + Hoymiles microinverter x 4 - system size 7.2kWp (12 panels) - RM22.5k

Is the system setup good for a single phase? Are there any other factors to consider before deciding which one to go? The TNB contract mentioned for a single phase the solar output should not exceed 5kW so the extra kW installed will be a waste?

The Hoymiles model is HMS-2000-4T

It is actually microinverter x 3, typo in my earlier msg

Any idea hoymilles 2000 microinverter , is it compatible with battery, as nem only last 10 years , and we are on our own after that

7.26kWp Solar System
RM22,000

N-Type 600W Half-cut Monocrystalline
PV Modules Trina Solar brand (Tier 1
Solar PV panel; China); or equivalent

Huawei Inverter (China) -SUN2000
5KTL

the panel actually not that expensive.
it already drop 90% for past decade.

the cost is installation, Inverter, panel bracket and etc
which i see hard to go down, it will go up only.

Hi All,

This is the survey I did during the previous HOMEDEC Expo @ KL Convention Centre

6. SOLS Energy
- Contacted by the sales consultant after a week of enquiries. He set up a hybrid meeting on the next day, end up he did not show up in the meeting. Very bad and slow services. Will not follow up or deal with them.

Shorlisted 1. PlusMax Engineering, 2. Pathgreen & 3.Verdant Solar. Still don't know which to go for

In layman terms, what is the implication of this certificate for consumers like us? And we talking about Pathgreen?
