For you usage scenario, how much you plan to generate or saved... seems quite a huge difference. First one will generate about 650kw, while second only generate about 500kw. How much unit you use monthly?

rm400 ave tnb bil. of course might choose for max kwp but it also depends on roof area.

Had an installer come to my house and give me a quote, due to my roof being made up of multiple pyramid shapes, they suggest to do a separate structure on the roof to hold all the solar panels. Unfortunately, the cost have gone up by RM7k. Anyone knows which company has smaller panels so I can install without the structure?

Worst than this?

I think mine is probably worse. On the triangle shaped side, max can only put 2 panels and this is only possible for 2 sides. All other sides can only fit in 1 panel each. The panels are around 2m x 1m.

Better go for micro inverter or possible to use panels as garage rooftop awning?

Thanks, will talk to a few other installers and see what options I have.

Does the roof area enough to house the panels, if yes, don't waste money to erect additional structure. Just get installer that can provide micro inverter will do.

Wow.. RM400 TnB bill, you better gee the larger one available and if possible get an even higher one 8 or 9kw system . No need to consider the 5.55kw system, too small and inefficient for your household.

have to upgrade to 3P liao..spend for 7-8k

does upgrade 3P requires so much ? I was quoted by much lower cost..

Oh I see, tough choice you have there. then need to consider a few factors lo. If this is like your home for the next 10 years, then can consider to invest more to change to 3 phase... if planning to upgrade, then maybe no need. just apply within the limit. Anyway, you will get ROI fast.

Hi all,
For those on NEM, does ICPT charge incurred after the Nett (import - export) is derived or it is purely based on Total Import ? Tks.

Not based on Nett, based on total imports....
but on the bright side, in day time, your imports is far less or zero as your solar is generating for your own consumption and exporting.

Tks.. but night is when most power is drawn from the grid..

Today installer came to install the system at my house. Very professional, they are seasoned pros and know exactly what they are doing.

9am start work after some chit chat. 2pm all done.

Very happy with the installation of my inverter, decided to put it outside my porch with space right below it for batteries 10 years later.

From which solar company? Good price?

ERS. PM me your name and contact I’ll get them call you, VIP treatment. They are very busy and swamped now as with all other installers.

Price is competitive but most important for me is that they install 3 phase inverter for my 3 phase power. Some installers will insist single phase inverter is fine (it is, just not optimized for you!).

Thanks bro, will pm you. Most installers busy nowadays, they got no time to layan me.

Could share the system capacity & the price you pay?
