SEDA quota is for FiT on grid.  You will offer REPPA and need to install and commerce the system by a date. You sell 100% electricity to TNB and get paid according to the rate. (for <4kW with retrofit panel at roof, 2013 - RM1.3708 / 2014 - RM1.2612) So, obviously, the sooner be better. You can apply first but you need to find installer to do all documentation for you.

If you want to do off grid, it is not practical and not logic. Solar panel not enough to sustain your house demand and you need battery to store electricity for night. battery will cost you an arm
*
The documentation is putting me off from apply. Too many form and don't understand at all. The application step is headache. It somehow, you cannot do this thing by yourself. Need to appoint an installer. Wonder can install by myself and appoint installer submit the documentation and approval.

Not mistaken the fit rate for 2012 - 1.23, 2013 - 1.13 and 2014 - 1.04. 21yrs contract.

Initial thinking to just sustain my whole house light only. Not the whole house. But doing off grid will not get 100% output from the panel.

Have you install the solar panel or going to apply? What is your experience about this?

You can contact the service provider / installer company, they'll do everything for you. Just sign, and pay money. Dont even need to leave your house. :-)

Yeah. It is the easy way. But costly also. Guess this kind PV not for poor ppl like me. Still far away from effort. sad.gif

Ha!! Documentation..... My advice is let installer do it for you. One of the documentation is system design, which need certified engineer to approve it. I like to know, what is your plan to install by yourself? Where u going to buy solar panel, inverter, cables, junction box, roof mountings etc. All these need to be reasonable priced and will the distributor going to sell you only 1 unit?

Off grid with battery will cost a lot, mainly due to battery price.
From my rough calculation, installing solar panel just to off set household electricity consumption will take around 18-20 yr to recover the installation cost. With FiT, the rate will recover the cost around 5-6 yrs.

FiT rate which I referring to is
Fit Rate = PV rate + bonus install as building material + local manufactured panel = 1.1316+0.2392 0.0276= RM1.39
can refer www.seda.gov.my

I'm in the process to submit application through installer. So far, what I know is all based on internet and discussion with installers.
My initial plan is buy the PV parts, install myself. Than apply for the FIT. Thinking save some cost. But it much more complicated than what I think. Not the technical side. But the application side.

Getting the solar panel and others parts is not difficult for me. It is pretty easy. And I can get it much more cheaper than the local installer. Can instal by myself too.

Actually the battery is 1/2 of the panel cost. Depend how many whr you need.

For the Fit, have you factor in the maintainance cost, parts replacement cost (specially the inverter) and the tax on the income? What is the return when factor in this?

Local panel is not efficency and only 1 manfacturing from kuantan supply. Mostly local PV manufacturing (investor) don't sell locally and export out only. It is a joke when we have many PV amnufacturing. But can't buy even 1pcs.

Maybe you can gain another 0.25 if you use it as building material. Takeout your roof and replace with the PV.

How many KW you intend to install and the cost?

My plan is 6-8kW by financing. Panel should be Yingli/Trina/Suntech, either one of major China manufacturer.  Cost still nego. Anyway, price is around RM10k/kW. If go for Euro/Japs brand, cost around RM12.5k/kW

wz3k, what's your plan? how much?
If you to install first and latter apply FIT, you can start with small scale, install panel with micro inverter. Later on, if you want to apply FIT, you can install more panels with string inverter. The panels with micro inverter can continue to supply with new panels.

Where to buy the panel and other parts? Panel and parts warranty?
Maintenance cost: One installer offer me panel & inverter with 10yrs equipment warranty and 2 yrs free onsite trouble fixing. Cost will recovered by 6yrs. So, 10yrs warranty should be ok but make sure the installer don't bankrupt.
*
By financing, you mean take bank loan? SEDA already comeout the bank loan list? What is the interest rate? I thaught SEDA still teaching the bank what is PV.

The installer offer me 16k/kw. German panel and inverter. No china panel as efficeincy is low. If I source by myself, can get cheaper. Warranty still have. But shipping cost have to settle by myself. Parts is from US. Micro inverter is still expensive. But if getting popular and price drop, can consider. DCV panel have more option for me to modify and play around.

Most of the installer will separate the parts warranty. Panel mostly can give over 10yrs warranty. While other parts is vary between 2-5yrs.

How about insuarance?

Financing is still pending from installer to arrange. If dun get, will go for 4kW.

The price offered to you is high (IMHO). I don't believe the China panel is inferior than Euro. You can compare the 'true' efficiency of panel in California gov website http://www.gosolarcalifornia.ca.gov/equipment/
Other equipments available as well. The California government take up initiative to set up test lab to do testing and review the solar related products. So, it is a good source for reference.

The installer offered separate warranty for panel and inverter but each has 10 yrs warranty.

Insurance? I don't think any available now.

BTW, PV FIT application is available from 24 Sept
*
So far what I know, 16k/kw is about average. Since it is german system they offer, I guess the price is about there. They don't offer china panel cause the data efficiency is not that good.

The insuarance is not from the local. The whole system is insuare by the german PV manufacturing appoint insuarance company. Which is from german too. They cover the system defect, lost and even income lost due to product.

If you want to have real local pv output data, check here -> http://www.cooltek.org/pv-solar.php Download the pdf report. This guy have 4.8kwp since 2007 and record everyday output power of his PV. He complaining about TNB late payment for his FIT.

has anyone of you guys done a ROI calculation? last time (early 2011) i got a proposal done for for approx. 23 kWp with kyocera panels and Kaco inverter. price per kWp 15k++.

i take it prices have dropped a lot in the meantime? then it might be financially feasable to go through with it. what's the typical actual ROI for a lifespan of 20 yrs assuming the panel is worthless by then all things considered (maintenance, insurance for the system, tax etc.)? when i did the calculation in 2011 actual ROI was below FD rate so i didnt go through with it - i need to finance the installation through a loan obviously.

would love to share information and experiences with you guys.
*
The ROI did put me off from proceed further. Unless I did it my way. Which I get the system myself and install. Way cheaper alot.

For resindential, the max is 12kwp. For 23kwp, you need to apply under cormercial quota. And the rate much more lower.

Your calculation take care most consideration, especially the income tax. I forget bout that one.

but since you include write off in calculation I think you need to modify a bit. Panel life span is long. It has 1% production reduction every yr and inverter has shorter life span, around 10yrs. So, the write off should consider these elements. Too bad I don't know how to calculate.

Which insurance company offering protection to PV system? Could you share?
*
Even the panel lifespan is long, your contract with TNB is max 21yrs. Should we calculate till 21yrs?

Long as it state? Or actually being tested ? Just like led, it last long but performance drop after continues used for few years. Brightness drop.
*
The efficiency will drop every yrs. So till end of your contract 21yrs, don't think your income will be the same.

At here due to hot weather, the performance will be drop further. Solar panel work best when cool clear sunny day.

ozak,

where did you get the info that max is 12 kwp for residential? we prepared the entire proposal and all in feb 2011 and noone objected or pointed out a max. kwp per application. did the rules change?

if you can make it large, it should be done due to economies of scale. no point in many small setups if you can do one that covers the entire roof right?
*
I get the information from the installer who conduct the workshop. The quota seems from the SEDA. I only remember the individual which max is 12kw. For commercial something like Mw max. While the farm type, need to have najib contact. Otherwise no installer can help you.

Many rule doesn't make sense and seems like protect themselve. Like the yearly quota. Why to have quota to limit the application? Gov have a target of 17% till 2030 for RE. The explain is, TNB don't have much free money to give?

Now they use solar to boil water, the steam to drive generator. This are more economical and efficient. But need larger area. If got concrete roof maybe can consider  ;-)

I wonder the solar heater here can achieve this boiling point or not. I can see something can invent from there. tongue.gif

Why have quota limit? Bcoz SEDA has limited funding. We pay only extra 1% on electricity bill for RE FIT rate. RE FIT rate is 3 times higher our residential electricity rate.
*
I read somewhere that inorder to supply 1kw to a house, TNB need to generate 3kw. Much of the energy lost at the transmiting and converting. If residential generate the electricity of it own, that save the TNB of 2kw. So why need funding?

Residential electricity is subsidy. I believe TNB don't get much profit from residential or probaly lost. If residential can generate it own electricity, TNB can transfer the much need to the commercial use which have better rate. Ain't this give better profit to TNB. So why to have quota?

Gov or TNB is subsidy our electricity. If residential generate it own electricity, TNB don't need to pay more subsidy. Can they use the subsidy to pay some portion for the FIT? That don't require our funding.

YTL generate power and sell to TNB. We are smaller scale of YTL. What rate do TNB given to YTL?

This is totally spinning and misleading! I'm in power generation industry. The biggest loser fuel price is Petronas. Petronas has to sell fuel to TNB/IPP and super cheap fixed price. The electricity price we are paying now is artificial.

3kW generation to supply resident 1kW usage. The one who tell you..... I cannot find a suitable word to describe the guy.
Transmission and distribution has efficiency more than 90% If 3kW generate from power plant and supply to grid, the consumer can receive 2.8++kW.
TNB did well in transmission and distribution.

RE FIT rate is paid by 1% surcharge on our electricity bill. TNB collect the 1% surcharge and pay to RE FIT installer. SEDA is monitoring all these. TNB is buying electricity less than RM0.20/kWh from TNB and IPP power plant. This price is artificial bcoz fuel price is subsidized by Petronas.
*
Here about the power lost. -> http://www.solarvoltaic.com/ Under " So why do we have AC 240V if everything is DC? "

I thaught the main is gas, 2nd is coal and 3rd is hydro? And coming is nuclear energy which decide by 2014.

Yup, the elctricity price here is artificial, 1 of the reason why we don't need RE at the moment.

'So why do we have AC 240V if everything is DC?' is nonsense.
Msia transmit electricity in High Voltage AC (275kW etc) and when reach near to user end, the voltage will reduced by transformer till 415V.
The 300% loss is misleading but I believe they are taking energy efficiency from fuel to user end. Power plant has efficiency from 35-55% (latest tech has higher efficiency) If included the loss in transmission and distribution, from fuel to user end energy efficiency is 30-50%

Thanks for correcting that stupid website. But you need to comeout some link or reading for us to read and believe. We don't no about power generation.

So are you decide to go ahead with the Fit? Does the ROI look good to you after some mis calculation?

the ROI with income tax and write off is really low. however ,income tax is depends on your total income. Maybe ask retired father to apply. for write off, i take it as buying a car. We can dump 100k for Japanese car yet no income, why not go for FIT
*
The house property need to be your name if you apply for Fit.

I wish you can go ahead with the Fit even the ROI is not so convincing for your earning sense. Combine other like your interest, RE and CO2, guess contribute abit is not that difficult.

Let us know your progress, experience go through all the progress, some picture and the data. At least we have some first hand story about this so new Fit thing.

Not neccessary. Apply the quota first if everything haven't done. The installer will help you with the online form. The quota have grace period of many mth. So slow slow no problem. This is told by installer.

Another important thing is don't forget to register reppa with seda.

Bcoz of the regulations, you must have certified person to do all doc jobs. So, I think you can apply quota in 2013 or 2014. You wait the price comes down.
Anyway, the few big solar panel companies in difficult financial position now. If they bankrupt and supply reduced, price may goes up.
*
There is possible 2 situation for price up or price down. Remember even if the price material is down, the labour and logistic will up yrs by yrs. So probably the price will be no different or even up.

If the PV market become popular here, the competitor hit up. Hence, the price will drop. But possible crap material to cut cost.

Why the seda Fit rate lower by yrs? Possible because of price drop for installation they forecast?

Suprising, even some going bankrupt but the demanding is still high. The bankrupt is cause of price compete. And not because of low demand. The good example is, local PV maufacturing. You can't even buy 1 from them.
