Finally installing solar. Got this quotation before the 4k solaris rebate

Hi everyone, I plan to install solar system too. My house is single phase, average bill around RM500/month. Been reading this thread and would like to know main advantages of three phase over single phase inverter.

Is it worth upgrading to three phase for long run or just stick with single phase.

Appreciate it guys for sharing. Many thanks 🙏

I’ve got several quotation. The cheapest is from solarsave by Itrimas. Any good about them? Hard to find reviews

hi guys... thinking of small 1kwp (500-600w panelx2) diy for ev charging... which one you prefer?

1. panels --> charge controller --> inverter --> charger/car
2. panels --> hybrid inverter --> charger/car
3. panels --> micro inverter --> charger/car
4. panels --> power station --> charger/car

will 1 and 2 work without battery? otherwise may need a small battery to trick the system... sorry for noob question, got no solar experience

estimated cost 2.5-3k... roi 1.5-2 yrs

car sits at home in the day, plenty of daylight hours...

??? these are the basics for solar pv right?

what is your estimate i should use for 2 panels and 1 inverter for ~1kw system?

the granny brick is rated 2.3kw... usually i think it charges lower around 1.8kw (my main wallbox is 7kw but i set it up for 5kw to reduce cable loss)

originally i was thinking a 1kwp grid tie or off grid for a 1hp aircon for day use... then i was thinking maybe i can use it to slow charge the ev... the ev can limit charging power but i can't remember how low it can go... I'll have to do some more testing to finalize kwp... grid tie will be easiest to supplement ac power...

my usual tnb bill is 250...ev adds 150... so a small system for the ev that i can diy i think will be more cost effective than going 5-7kwp nem for the whole house...

anyways... thank you for taking an interest...

This is what i saw on some other house in my neighbourhood. But the solar company i asked about this and they refuse to recommend this method. Dont know why, they just said it wont work..

I got a quotation from a contractor, estimated roi 2.7 years..seems like a good ROI

Guys, advice please..
My electricity bill around 80 but I just got an ev so expect to reach 230-250..
1. 15 yr old Double storey terrace house in Melaka East West orientation with 3 phase
2. Saw an advert for 3.92kWp for less than 13k with 60 months instalment... Is this suitable for me or can recommend anything else..
3. Need to wait for how many months bill before can apply? Last month bill 200
Not looking at ROI.. The way I look at it, if 15k over 60 months is 250 per month which is almost what I have to pay to tnb... No more guilty about switching on aircon in daytime..
Thanks

12 kwp for single phase...

So guys,
Anyone got suggestions on which companies to consider and their contacts, can pm me.. Thanks

my simple estimates... keep here for my use...

but feel free to comment 

sun hours could use 3.3, but if not hitting mileage should be ok i think...

It doesn’t work this way.

Wha you are calculating is dc. So u will need a dc gun.  For charging.

Meanwhile , the usual gun we have at home it ac.  So u can’t purely use solar to charge.

shit man

may i bantai aircon je, almost 3-4 biji on whole day

main sampai 1522kw, kena penalty icpt (around 150 ccb)... my solar pun x cover all..

got to pay rm500

normal days around 20-50 only... kns...

I thought will increase price for energy unit? Enough to offset the icpt ?

Got quoted total rm61k...but comes with rm1100 worth of tnb bill..

Hahaha.

I hv not much detail too

Paying installment of rm1700 for 3yrs. 0%
Enjoying government scheme rm4k.

Monthly tnb bill rebate capacity is rm1100.

Which means indirectly im paying just rm600 for the solar system cause now my monthly bill also around rm1k.

On 3rd year onwards , my electricity is basically free. Thats if i utilise less than rm1100
Yepp.

Macam tiada 3 phase micro inverter.

No need get biracial if you gonna put on roof, the other side basically shaded. Just get the mono facial enough. Bifacial also more fragile cuz both side also glass panel.

Better to have string inverter on single side. Next time you can upgrade inverter with battery storage option when your nem contract habis

Other than GSPARX, any other companies with good reputations? If you checked the responses in Google Review, GSPARX isn't that impressive.

Hmm... I'm not sure if it is a build in function for the inverter because for Malaysia NEM, the inverter is place after the distribution board that connect to the meter. So the switching will be at the distribution board, not on the inverter. If the switching function is on the inverter, then it need to be place between meter and distribution board.

Yup, but anyway, as you mention not that it cannot be done, but it certainly not a DIY solution or general electrician work scope.
It need to be carefully calculated on the max and min load and also switching time.

Basically you measure the power of your house load and determine if there is a need to switch supplement from TNB feed. The cost of implementing this totally defeat the purpose of cost savings.
