you are right that it took at lest 4 months. Mine comissioned at aroung end of Dec 2012 but my first payment was made in April 2013.

Hi all,
mine commissioned at end Dec 2012 also, and my 1st payment was made in end May 2013, 2nd payment made at 1st July, then stop until now, don't know why? I will check it after Hari Merdeka.
I install 11.25 KW system. invest RM135k, (a litter high at that time, but use German panel, inverter & wire)
my Avg. Performance /kWp is 4.00+ (Kedah). Base on TNB meter calculation, until now I get RM2,200+ avg. per month.

Before i start last year, discuss with my "long hair partner", we decide to dump in this "BUSINESS" base on d reason below:
1. SOLAR business is good than to start a new business. To run a new business, we also need to spend a few K for renovation, shop renting, hiring staff, buying material, our time to JAGA the staff n money n this and that. (solar no need to do all this). And still we don't know whether d business can get RM2,000 net income instantly or not. Talk about maintainance, running business also got maintainance ; aircon leaking, water, electrict bill, staff din't come to work, customer complaint, transport etc. all the headace problem. Dont no right or not, in KEDAH, RM2000 for a business is a quite good business. Yet I can still run my existing business with no worry about my second business.
2. My few friend do more than 3 lot of solar, 12+12+12 for each house and shoplot. I Consult with them (some r developer, professioner, business man, Bird house owner(with no bird nest in the house cry.gif ), they say, "u calculate n see, u refinance your shop lot and do the solar, worth it." So I pinjam bank 15 yr. n pay Rm1,100+- monthly installment. Now with the contra, I get +-RM1,000.00 (RM2200-RM1100) each month buta buta.
3. Worth then put the money in the FD.

Bro avereng cheers.gif

Bro ywkwy, my RM1000 per month income is TNB solar system bill RM2200 minus my shop loan RM1100 monthly instalment.

May I know those who get payment from TNB, is ur system serve all ur electricity needs and those excess sell back to TNB?

we sell 100% electric to TNB. For this matter, Bro avereng is very good in explanation, Bro avereng, can u pls give full detail? icon_question.gif

I assumed you dont get 5.2+kwh/kwp everyday? What is your monthly kwh/kwp? From what i seem, most service provider only suggest 3.2-3.6kwh/kwp for their system.
Do you mind to share your average kwh/kwp for the 21 day so that i can have a idea of how good sunpower panel perform.
*
Hi,
i m new here. i m from Kedah. My best daily performance is 6+kWh/kWp ( just for 2 day only). My 11.25 kw system T & C at Dec 2012. The average performance until now is 4.2kwh/kwp. (i don know how to calculate the out put rate, nor don understand what is kVar or exp kWh. because my KACO inverter just show simple number at the small LED screen, i have to press a button each time to read something that i don't know. I just know to divide the total TNB meter reading by day, then by 11.25, and get the average performance, am i right?). i use German Qcell solar panel.
My second 12kw system had just complete install and waiting for TNB T & C metering. This time I use Korean Hanwa(Made in China) solar panel and German KACO inverter. And in future i m planing to install my 3rd system with China brand solar panel with German KACO inverter. At that time, sure we will know the performance of each of the solar system, but still depand on the position of facing of the solar to the sun.
I had install a speed dome CCTV on top of the roof. in future i will update d CCTV net work system and you all can see live of my solar. u even can zoom and pan tilt go left right up down. smile.gif .

I agree the nature of the roof top plays a big part in the system performance.  From the camera, I believe you do not have any shading problem and all of you panels start working as soon as there is sun.  Not like most of us where we do not have ideal roof condition where shading is one of the biggest negative factor.  For my case, only 60% of my panels are exposed to full sunlight in the morning.  Overall my system only have full sunlight exposure(no shading) from around 11am - 4pm.  Beyond this timing, the system is not operating at full speed.
*
Yes, my roof is very "beautiful", do not have any shading problem and all of the panels start working as soon as there is sun. I will update my SEPT n OCT performs later.

From what i know, Penang and Kedah get most sun light amount Malaysia, Especially Bayan Lepas near Penang Air Port.

TNB had replace my new meter at the middle of August and I always record the meter reading at Thursday morning.
The reading at 29/8/2013 is 254
the reading at 31/10/2013 is 3057
3057-254 =2803, 2803 /63 days =44.49
44.49 / 11.25kwh system = 3.95
3.95 is my SEPT n OCT performs. hmm.gif

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 ...
*
My 1st system T&C at DEC 2012 used both German brand panel & inverter cost me RM12,000 per KW (maybe is higher but reasonable at that time).

This year, my 2nd system used Korean panel & German Inverter (which has completed installation last 2 month and still waiting for T&C right now vmad.gif ) cost me RM9,000 per KW. Vendor quote me RM10,000 per KW if I use both German panel & inverter.

I'm considering to install 3rd system in 2014, vendor quote me and my friend RM10.00-8% (RM9,200) per KW, if I use both German panel & inverter.

The last payment for my 1st system is end of DEC 2013, which TNB should be bank in my AFFIN BANK A/C. BUT they didn't. They bank in to my second system's bank a/c. My second system just T&C at end of DEC 2013. My SP phone TNB, they said all payment will bank in 1 account only.

Hi brother kd8800, how was your system performed over the past 2 months in Jan and Feb.  I guess your system should be performing very well.

reading at 28/11/2013 =4291kwh
reading at 27/2/2014 =8629kwh
amount get is (8629-4291) = 4338kwh for 91 days.
4338/91 = 47.67kwh per day.
47.67kwh/11.25kwp =4.23kwh/kwp.

I think this is not the highest rate I get, according to my last year record, the highest kwh/kwp I get is 5.4 for March and April.
Wait until then and see.

hi,
every sifu, below are 4 option of installation for a roof of 10kw.
Which is the best choice?

1. Hanwa panel (waranty 12 yrs) + Kaco inverter (waranty 5+2 yrs).
2. Canadian panel (waranty 12 yrs) + Kaco inverter (waranty 5+2 yrs).
3. Hanwa panel (waranty 12 yrs) + Solaredge inverter (waranty 12 yrs) c/w OPTIMIZER module fix in every panel on the roof.
4. Canadian panel (waranty 12 yrs) + Solaredge inverter (waranty 12 yrs) c/w OPTIMIZER module fix in every panel on the roof.

All the price are the same, but add extra RM3,000.00 for option 3 and 4. (RM300.00 per KW, SP said it is special offer).

Google the Solaredge web site, this inverter is very strong in monitoring program, it can monitor every panel on the roof,make a roof plan and...............many many more, it support Android and Iphone. They said the OPTIMIZER can incress the eficiency of the power and...... (go google it.). Waranty 12 yrs thumbup.gif

Are you sure it is RM300/kW? It is too cheap. What is the overall price offered?

I've never heard of Inverter Optimizer before. I thought the Solar Panel is the most important component in the installation? How does the optimizer works?

For 10 kw project:

no1. RM85,000.00
no2. RM85,000.00
no3. RM88,000.00
no4. RM88,000.00

This is also my 1st time heart about OPTIMIZER. Go google it.

Back to technical spec of solar system
As an engineer, I believed in specification and not in brand.

Panasonic does produce good panel. It is Panasonic HIT panel which is very expensive. 
Panasonic panel which is widely use in Malaysia is polycrystalline panel. Polycrystalline panel is very common and usually 250W per pcs. Monocrystalline panel is less popular but I don't know why.

Important point to check Temperature Coefficient of Max Power. It should be -0.4%/°C or less. Anything more than -0.42%/°C should be avoid. This will greatly reduce your power generation.

25 yrs performance warranty & 10 yrs workmanship warranty are norm and nothing to shout about.

If you compare several polycrystalline panel from different manufacturers, you will find they all very similar.

Inverter has 2 type, forced cooling (with fan) and natural cooling (without fan)
I'm fans of natural cooling inverter as I don't trust cooling fan for long lasting. Cooling fan has moving part (ie bearing, carbon brush etc) which has limited life span. Natural cooling inverter comes with big aluminum heat sink and no fan required. Any way, forced cooling inverter tends to have lower operating temperature for internal parts and may have slightly better efficiency.

Forced cooling inverter normally has smaller size than natural cooling inverter. Champ of forced cooling inverter is SMA. Champs of natural cooling inverter is Power-one/ABB, Huawei(3 phase only)

Efficiency of inverter is important. The bigger capacity, the better efficiency. When compare inverter efficiency for different brand, remember to compare on same capacity.
You can check inverter testing report on Photon magazine

good tip. My 3rd FIT project of 10kw will start next week. This time I use Canadian Solar panel and inverter, biggrin.gif cost less.

Why so many forumer get the unit wrong?

DAA estimation calculation is
12kWp x 4hr/day x 365day/yr = 17520kWh or 17.52MWh

4hr/day is consider high. Prior 2013, most SI estimate 3.5 - 3.7hr/day.
All ISPQ engineers were very honest.

avereng, mine is d same, my DAA is 15MWh for 11.25 kWp system , install at Jan 2013. My place is at Kedah. I espect my SI calculate with 3.7hr/day, by right , Kedah can get more than 4 hr/day. what can we do? I just notice I only get around RM800 for d month of NOV and DEC for d year 2013 and 2014. vmad.gif

Wow, after installing aluminum sheets still leak, need to look for the leak source and fix it. If need to, have to take out a few panel to so better than putting silicone as this is not fixing the cause of the leak... I know say is easy, sometimes dealing with errant service provider can be a headache.. maybe you may need to complaint them as suggested by some forumer here...

My first shop house roof is clip lock metal sheet, its ok and no leaking. .But I still call my SP to put C channel, then add extra metal sheet on top of it. So, I got double metal sheet roof. Double protection. It cost me around RM9,000.00. D second shop house is cement roof tile, d tile is very "teruk" , many crack. I call my SP to take out all the tiles and replace with metal roof, then only they fix solar panel on top of it, it cost me RM5,000.00. All d 2 shophouse complete with "BOMBA LADDER", So I can climb up to the roof very easily.
My own house is roof tile, I did not do anything for it as its still new, (7 year) and no leaking. Last month d SP just finish fixing all d panel and inverter and wiring, just waiting d meter.
