What’s ur capacity? From there can calculate the sun hours

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.

It depends on the system size. For example, a 40k system from company A , at a difference of 8% is going to be 3.8k more.

This will affect the ROI in long term.

For smaller system, the roi is already long, so even an 8% difference will have significant delay on the roi, making it not so worth anymore for the hassle.

But yes, always compare few prices, and the specs of the packages you will get coz it’s a system that you are going to use for long term. Get what you are comfortable with.

For smaller system, based on my experience, the difference isn’t that big, because most solar companies has a minimum price that they want for each project. They are not so keen on small project nowadays. Doing a 4kwp project takes a similar time for completing a 9kwp project, so they don’t really look at smaller project. But if willing to dig further, perhaps the difference could be quite big too based on my experience. It could be larger than 8%. I would say the Tnb company price is usually 20% or more than others most of the time

There are lots of diy in Facebook section. But it’s not for faint heated. Coz u need to know some knowledge, and wiring, and hands-on to fix if anything goes wrong. Everytime call electrician to come, jialat already.

Not that I encourage that. But some people prefer to do their own out of cheaper cost.

In my opinion, this kind of money u can’t save. As long within roi that you are comfortable, then it’s better to engage solar companies. I don’t really encourage buy panel here, buy inverter there, buy wire here, employ worker to fix, and nem vendor Jsut to help apply. Too much hassle. And so many things may go wrong.

I know a few reputable companies in kl thst cover installation from north to south. Only east they don’t cover coz they don’t have nem. So it’s really depending on how u find and nego. If you don’t know what is considered good prices and good system, u might see there isn’t a big difference between gspark and other companies. Coz most of the time, their initial quote will be similar especially for smaller kwp. So it’s best to know the cheapest price for a system of same kwp, and work from there. , only then u can compare and see the real difference. I roughly know some prices for small sized systems and the range you should look at.

I do agree if the price isn’t that big difference, might as well got for the more reputable one or a better system.

Ic. So your total Feb production is 1397.27?

That translate to 3.67 Sun hour.

Slightly better than usually promised 3.5sun hour.

Where is your location?

Eh. Btw, where is Accord2018 today? He’s absent from my solar lesson.

Don’t think so. He can afford an accord ler. From the nick


But some ppl really skeptical due to misinformation they get. Just like how some ppl detest ev. Everytime got one ev goes kaboom, they straight become excited to condemn.

Ur system size again? I avoided icpt charges this time. Though my actual usage is around 1600kwh

Okay so your main concern is if solar is really reliable and won’t rosak after 11 years.

Solar component got two main part that might give u problem and cost a significant amount to repair or replace.

1. Inverter
2. Panel

For maintenance, like cleaning, we keep it to another discussion if u want to know later.

For inverter, the warranty is 5 years for string and 12 years for micro. These two warranty can be extended to 10 and 25 years respectively.

So yes, for string, u most likely need to replace in year 11, cos it’s almost at the end of its lifespan. For micro it can last longer than that. So to be safe, choose micro. When the manufacturer can promise that long, it means the item can really last that long most of the time.

2. For panel, warranty is usually 25 years. So it’s a non issue.


In order for you to have these warranty, it’s advisable to get from reputable or those who are already long in the solar game and have solid performance. This one you will need to do some homework like getting their ssm to check out their company health. If you want to be in so detailed lah. So , as long the company has solid ground, your warranty should cover 10 years at least.

Meanwhile, another thing is to make sure the Roi is well within 10 years. If can get between 5-7 years is still quite a good one. That’s why the price is a big factor here. Once ur roi met and achieved, u no longer rugi kan. And u don’t need to worry about warranty anymore if shit happens.

Once ur roi is achieved, u don’t need to worry 11th year anymore. Coz 11 years onwards, u should expect to cough up a little bit more for battery storage system anyway. And the cycle continues until ur roi is met again.

Ur place kl so efficient? Already got ur Feb bill? My place still haven’t got. Usually after 2 - 3 days.

Ok. Pm u later

Yes. It is. But u need higher than that coz it’s 4kwac.

U need about 5-6kwp panels usually.

Yes.

Sure.

Pm u later.

Can. For sure can. In fact u should go for it lah.

This one all my credit burn. Simply put, January start from 0

My Nov extra also gone.
