If you says that he has 10 years of fit left, means that he has used the panel for 15 years already. 

And to think that the panel on those days can last 15 years that time, it’s quite impressive already. 

But iinm, u cannot increase the capacity of the kw for fit. They are very strict with that.

Yea. There is a risk of solar company disappear or gulung jor. So it’s best to get from companies with a longer history in the business I guess.

So what will you suggest to be use to evaluate as in your opinion you think that ROI it is not reliable?

For common consumers... the tariff... which can be tracked all through the years is easy to understand and can be use fairly easily to know if one earn or loss from his Solar project. That will be the predicted ROI.

Of course you are not totally wrong as the ROI is calculated based on current and previous tariff which is predicted to constantly increase. But who know suddenly there is a new oid field found and oil price drop dirt cheap and electric tariff follow suit, or some mad scientist suddenly able to produce electricity out of thin air and electricity tarif price drop rendering solar ROI to zero.

Accroding to google, FiT is 21 years

But back then PV system is expensive, so despite the RM1.49 FiT, The ROI is expected around 7~8 years

Satisfy?

Under testing only 3kW. Tuition cost ver high

My area is 4.49 sun hour average for the whole February.

The hoymiles total 1.8kW(1.932kW) is the limit, extra panels wattage get you more power when weather not so good.

When a panel is rated at 575w or 600w, this is the STC value.

The best is referring to noct value.

Like ev, one is nedc value , another is wltp value.

So to achieve full panel outpu as per stc value, u need to see certain criteria met.

So clipping is considered minimal with the pairing while the spread is higher during non peak hours. Which is quite optimum.

One is in dc and one is in ac.

That’s  the difference.
The panel output that you see is in dc, while the inverter rating is in ac. That’s why if u check your app, you will notice a slight difference between the overall capacity (big figure) and toto panel figure. Microinverter has about 95% efficiency. Same thing goes to string too.

Most buyers usually will lowball you on that!

Depends on your inverter brand & it's efficiency ratings.

First time I hear somebody saying Gsparx is good actually! Anyway some company in fact will only do 3 phase 10kW up. Labour & their time to do a bigger system not much difference so with market throwing prices it's just not worthwhile for the smaller company to do single phase 4-6kW. Anyway if anyone would like to do it more economically but you might need to spend some time to study the system yourself can asked me.  Like buying your own panels/inverter from China and getting NEM vendor to endorsed it.

Anyone tried installing solar panel on awning? Or better still, use solar panel as awning? I've plans to install awning at my parents' driveway, so thinking if its possible to do so. The driveway also gets unblock sunlight throughout the day.

I think 22k includes 3 phase already… how would I know how much is enough to cover my monthly usage?

Record breaking energy yield last month.

I got question on Inverter choice:
- can the mirco or string inverter be used with Battery Mgmt System in the future (after NEM completion) ?
- I was told we need 'hybrid' inverter. How much extra are we going to pay for this ?
- do you guys prepare your solar system to work with BMS in the future? Or modify your system later (eg change inverter type) when the time come ?
Thanks.

why not , they just need to split the microinverters into 3 phases.

The only problem is that they cannot balance it perfectly into 3 phases.

12 kwp for single phase...

In reality,  solar power generation can go up and down every minute, and it will be hard to monitor by regularly checking out the TNB metre.

Here is an example of my solar power generation (blue line) vs. my 2 HP non-inverter AC run at 27 °C (orange line) + other organic usage. Those solar energies not consumed will be exported to TNB unless you turn on all your AC (e.g., rooms, hall 1, hall 2, etc.) and set it to 16 °C. When the sun gets dimmer, switch off the AC one after another to match the actual generation.


There is zero export device from Hoymiles for their MicroInvert to prevent Solar energy from being exported (e.g. after NEM contract expired)
Zero Export Solution

If you are using a normal grid-powered inverter, if you cut off the TNB supply, the solar system will automatically shut down as well and leaving you black out.

If you are using a hybrid inverter, your battery storage system will warn you of low battery or power before it cut off the power to your house.

"big company should not profit from rakyat mentality"

Once the NEM 3.0 contract expires after 10 years, our contract with TNB will go from NEM to Selco (self-consumption).

Under Selco, we are technically not allowed or licensed to export excess energy to the TNB grid; thus, doing so will be considered illegal.

By reading your smart metre's exported energy remotely, they can automatically know whether you comply with the Selco agreement.
From the link below, the off-grid system is more toward remote area without direct access to grid system.

10 years from now, I believe you already start switching your old car from ICE to EV with half the current price.  So, your saving will continue to carry on in different form.

You can access individual panel generation? If yes, you will see that the max u can process is about 7.73kwdc.

And your front page should show 7.47kw.

The first page is showing kwac
The panel page the graph is kwdc

That’s why u hahve two different figure at the same time.

Kwdc is always higher than kwac.

His inverter rating is 1800, and for 2000, it’s a different ballgame dy.
