tomorrow NEM 3.0 open for application.....

i think about mid-teens return (not cash - set off TNB bill) if your bill > RM250.

Make sure you get at about RM4k per kw or lower.

Ensure its Grade 1 solar panel, and Grade 1 inverter. They'll try short change (curi ayam) you on these two items.

i'm not an installer so don't ask me for price.

Energy prep is a GOOD prep but don't rely solely on solar as the alternative energy source. Solar parts are expensive and can be difficult to find further down the road.

Are Solar parts are getting cheaper or expensive? Also getting lesser supply, is that what you are implying?

Hi,
I am a to be user. 6.12kWp I purchased and NEM contract only state 5.0kWac as declared install capacity. I look at the inverter also 5kW. I am confuse on this technical therefore want to know more of existing users. Hope you can share your technical info. Appreciate the help

solar installation now cheaper by 80% compared to 10 years ago.

you...sir.....are talking nonsense......

solar panels are getting cheaper every year. .....google Swanson's Law

6.12kw purchased ....solar panel ?
5.0kw inverter

ideally the solar panel kw should match the inverter kw.

however sometime SP curi ayam and reduced the inverter sizing a little. Inverter can be over-stressed a little during peak period. however the shelf life will be shorter. by that time the SP will tell you no more warranty. you are on your own.

ask him nicely to give you a 6kw inverter (maybe 2 x 3kw, if lucky can find single piece 6kw) otherwise you might go look for SEDA to report on SP who give bad advice.........same price of course....make sure decent quality inverter too..

aiya...why sell back to tnb and become thier kai_dai,

you already bought the cow, why kiamsiap for the rope!!

just build the power wall slowly and is at a very low cost nowadays.. then can live off-grid and show tnb this

No worries, nonsense or not, we'll see.

Thanks and good info. What the panel able to get peak is 6.12kWp DC, and the inverter output is 5kW AC. They claim technically must be between 1.2 - 1.4 ratio factor for energy lost... i have no clue on this. I do agree with you that if incoming is high to the incerter, it may load it and shorten the lifespan. Should make the future maintenance business for the contractor. .. hmm ...

more practical is look at the contract which you signed.....did the SP deliver what he promised. if yes, you don't have much recourse.....

Mine is will be 11.7 kwp and the inverter is 10kw ..... The ratio shud be 1.0-1.3

how do u clean the panel when it gets dirty? diy

Depends on installed capacity. If only install 3kwp maybe over 5k

I'm about to pull the trigger with GSPARX for a 4kwh system for RM20,500.00. Seems like a good price.

Gonna get a quotation for a 5kwh system to see the price difference. Our monthly bill is about 130-150rm.

Is GSPARX generally reputable? or other providers are recommended?

Going on the TNB/solar site shows a quotation of RM30k for a 5kwh system.

RM38k already can get a 11.7kw system, generally GSPARX is more expensive since they are part of TNB.

Rm150 monthly bill worth to get solar? How long will the roi?

Why not try mah bayu?

I think it'll be an overkill for us as our usage is only 450-500kwh per month. Don't mind going up to 5-6kwh system.

Gsparx process is quite simple. I filled a form online and got a nice deck with quotation, estimated savings, forms to sign, payment details etc. Very simple and no need to deal with any humans. Seems like quite a few here used them as well.


Based on their calculation its 10 years.

But based on my own calculation as I have access to 1% interest credit facility with no monthly repayments needed (lump sum payment at the end with interest), the money will be invested and I target 6 years ROI.


Ok will google them as well.

I don't mind paying more for high quality stuff. But it seems very difficult to get quality information on google. If anyone can vouch for any companies with high quality products and service albeit more expensive please let me know. A member has pm'ed me and I will contact more providers to get a comparison.

I will building a 1.2kwh solar for my farm soon with an hybrid 5KVA inverter.
Items will arive after CNY.
My order items contains a 16s BMS, LifePo4 x 16 200Ah, Solar cables 6mm, MC4 connector, solar rail and bracket, DC surge protector, circuit breaker,....
