For me my preliminary motive of installing this solar pv system is to reduce my carbon foot print ... In view of huge cost of investment, now this FIT came at the right time to subsidy us, thus the ROI is secondary, as long having 10 - 12% p.a I'm more than happy ...

Waiting the installation of mine which shall happen in next 2 weeks time ...

I just installed 4kWP system last week. Now waiting commissioning by TNB

My system

Capacity: 4.00kWp
Panel: BYD poly 250W
No of panel: 16 pcs
Orientation: 8 pieces North + 8 pieces East
Inverter: 1 pc PowerOne PVI-4.2

very curious now of the potential output ... would update after it is commission ....

My house located in Seri Kembangan, just beside Ayer Hitam Reserved Forest ... just wish to have average 400 kw averagw output pm from my system ...

Hi, how u install your monitoring tools? Sorry on my ignorance ya ...

Thanks, I would figure it out later

My 4kwp system which cost me of RM40k just completed the T&C 2 weeks ago.

My family and another of my friends are now considering to install this system early next year with 2014 quota.

Nevertheless for the same system of 4kwp, the same vendor has quoted my friend for RM42k, ie 5% increase in term of cost despite there would be a digression rate of 8% annually, ie by next year the fix rate from TNB would be RM1.26 compared to RM1.37 this year.

The reason of my vendor provided the increased of cost is due to 2 additional processes / regulation imposed by SEDA for next year installation :

1) DC chargeman endorsement is required
2) T&C required endorsement of SEDA personnel

Is anybody aware about this additional regulation? And would this affect the cost of installation?

The original plan of digression rate applied because market foresee the reduction of cost and increase competitiveness would force the reduce of installation. But now it seem not the way forward ... cost increase but rate of return decrease, thus it make the ROI not so attractive ...

Hi all Sifus,

Would like to post a question here .

Just noted if we are using local assembled solar panel, an additional rate of 3 cts per KW is entitled.

Would like to get a feedback / view on the the Q-cell solar panel which is manufactured in Malaysia with technology from Germany.

My initiate research on the net shown Q-cell is one the top brand for solar panel. Is this the case?

And how it is compared to Panasonic / BYD / Hanwha or any other solar panel?

Also appreciate feedback from forumers who has installed this Q-cell solar panel ...

Hi, Sir

If u don't mind, may I know the type of solar PV that u used? Poly crystal or Thin cell? and the system capacity?

Many thanks

Thanks, Bro. Would pm you if I need a contractor on this.

To all sifus again,

I just learnt during last weekend, there few types of solar panel. Out of two are :

1) Poly crystal
2) Thin cell

Noted the thin cell panel is more sensitive to Sun light and able to generate more KW if compared to Poly Crystal type. Only disadvantage of thin cell is the output per panel is lower thus more panels is required to make up the desired KW and of course with higher cost.

Eg 4KWp system for poly crystal panel may only required 16 panels (with 250kw output per panel) while thin cell panel normally is 150kw per panel.

However, I was informed the the 4KWp of thin cell panel able to generate much higher output compared to 4KWp poly crystal panel?

Can anybody enlighten me further on my above statements?

Many thanks ya

Thank you Sir.

I can always now compared with your system performance. Mine 4KWp system with BYD Poly crystalline 250kw with Aurora Power One inverter so far generated 218kw since 5 Dec 12pm till yesterday evening ...

Yup, my rate is RMR1.3708, the highest output per day thus far was 17.2KW achieved on 19 Dec ... not sure during peak month what would be the highest output per day look like ...

Would share more info on my system's output in future ...

Wish to have some knowledge sharing on 'thin film' vs 'crystalline' from forumers here .... thanks

Bro, simple calculation - 4000w / 300W = 13 panels give u 3900W / 3.9KW ...

Thanks Bro, for your very informative info.

I also did a research myself over the web. As mentioned the thin film panel perhaps are much better for 'Hot weather country' like Malaysia. But I also read few articles saying the thin film panel degrade faster than crystalline panel?

And also noted the installation cost of thin film are at least 20% higher too in Malaysia compared to crystalline panel mean lower cost efficiency?

With these shall we make a conclusion for time being installation of crystalline panel are better choice compare to tihn film especially the crystalline technology has been proven for the past 40-50 years?

Appreciate other's view on this ...

My 4KwP system was commission on 6 Dec (12pm). Exactly 3 months 1/2 day as of now :

Current reading (7pm of 6 March) = 1267 ( 1285 from Inverter reading), ie around 1.5% variant btw TNB and Inverter reading which should be a norm according to installer ...

1267 / 90.5 days = 14 kwh per day = 3.5 kwh / kwp ...

seem performance is poor for mine compared to you guys... despite it exactly tally with what my installer forecast earlier, ie 3.5 kwh / kwp average per day ...

And despite my system is 4000W, the max of day only reached around 3100 kw around 12-2 pm ... is this abnormal?

But for past 1 month after CNY, every performance is average at 17kwh per day / 4KwP = 4.25 kwh / kwp ... let hope later of the year would be better ...

My system located at Seri Kembangan ... Noted northern hvg higher irradiance but the different should not more than 5% ... the different perhaps due to other factors ... as I noted my area used to hv big cloud after lunch ...

You should seem u re convinced with ...

The only concern is the invoices that I received is without indication of units ...

Yup, just got e services done for my solar system, and it seem we need to call TNB hotline to obtain the account number of solar system before able to register e services as the invoices posted to us do not indicate the account number ...

and 2 different ID is required for e services if we also would like to link our normal consumption meter to e services ...

This is how TNB e services operated ...
