any company to recommend for Iskandar puteri johor?

Averagely how many kwh can this produce?

The opportunity cost can offset by the extra 700++ ts grts every months. There’s an opportunity cost in having extra disposable income too.

NEM system cannot install battery? what about after 10 years when the contract expire?

Can install afterwards.

As long as the hybrid inverter have IEC61727 certification you can used it with NEM & battery.

After speaking to about 6 companies and asking questions.

Here are my recommendation. Disclaimer, I am not affiliated anyway to the industry. I am just a soon to be consumer.

1. Some companies will bs story you, because their approach is to maximize profit. E.g. your house uses three phase power. They tell you single phase inverter will work. It is true, it will work, but it’s not optimize and it’s not best for you. Out of the 6 I spoke to, 4 of them tell me can install can use, which is true, but it’s not the best. It’s like selling you snow tires for use in Malaysia. It will work and can use. It’s just not the best choice available.

2. Choose a large company with long track record. Best if they have large corporate clients. Why? When you buy from them, they will be the one supporting you for the 10 year inverter warranty, 12 year panel warranty etc. Sure, Huawei inverters will be backed by Huawei Malaysia even if your installer close shop tomorrow. But it will be very hard to find another installer to touch your system and do the replacement for you. Nobody wants to clean up other people’s shit.

3. Out of 6 of the companies I spoke to, 2 of them is clueless. Just focus on selling. When I ask questions like send me the data sheet of inverter, she answer me the quote is based on my tnb bill. Don’t even know what I am asking for. Don’t even have basic product knowledge. Just sell sell sell — this company advertise heavily on Facebook, name start with a. Worse thing about them that scares me, they used to sell Canadian Solar panels. Now discontinued. Which makes me wonder if your panel got issue claim warranty, they don’t carry it anymore, what happens? Is the installer going to replace for you? Are they going to tell you sorry brand no longer in Malaysia you need to pay to replace with other brand? Make sure you ask.

4. Truth is, solar panel hardly needs cleaning in most cases. If the company start story say need cleaning, charge you how much. Can walk away. If your output got problem, maybe cleaning is one of the remedy — like Godzilla 💩 on your solar panel and the rain can’t wash it off. This is what the big company tell me. Usually don’t need.

Average save RM250 a month. You can go online find calculators. It’s a 5kW system.

Can install. But what is the benefit? You don’t want to draw so much from tnb grid to make sure you’re below monthly 1,500kW threshold? There’s a 10 cents surcharge per kWh if you exceed 1,500kW drawn from the grid. It applies even if you’re on NEM.

But even assuming the surcharge applies, 1501kW * RM0.10 = RM150.10. Per annum it’s RM1801.20. Current battery system costs way more than that.

There’s no clear ROI? Unless you’re consuming way more — but that also means you need a large battery and a huge solar system.

Huawei’s inverter is battery ready. Hopefully 10 years later the NEM gets renewed or the battery costs comes down. Yes yes Huawei supports proprietary batteries only and it’s HV battery. But you can still do AC coupled battery with inverter with the Huawei system. Same same.

can share the company you have talk to?
maybe can censored some word in between the company name. haha.

All this just PM lah.
Not nice to disclose public forum. Can refer you the person and company I chose. Already paid booking.

it’s my personal experience, observation and opinion and is only 1 case, and may not reflect the norm.

I don’t want to get sued.

Oh ya one more benefit in Malaysia versus those angmo countries like Australia and UK, our installers mostly use skylift. Damn hebat compare to Aus & UK where they mostly use ladders and carry the panels up the roof for installation.

I’m also going to request when they install the frame/support rail for panel to be bigger and to allow me to install extra panels in the future. Top up a bit more worth it.

My package comes with 5.4kWp panels on 5kW inverter.

I intend to ask how much to add 2 extra panels, and have space to accommodate a max of 16 panels. So in future can add panels or swap panels without having to touch the roof again. Of course mixing old panels and new ones not ideal, but it’s easier down the road.

Actually u will notice that most solar companies will just offer the brand of the panels they have in stock and they won’t stick to one single brand. I have seen many companies and their quotes, that changes brand over the time. Perhaps your company also no difference. They could bring two or more brands in and offer whichever which is in stock.

Usually for the panel warranty, the company will just replace with the similar wattage and claim the defective panels later with the manufacturer on credit note. That’s why a company which is reputable is better than those new companies.

Also that’s why to go for tier 1 panel companies, as they are more likely to storm the weather and last longer in the pv industry.

Huawei have both on grid and hybrid inverter. So please get your facts right, later somebody installed Huawei cannot add battery will surely blame you.

Tis good deal? Using huawei , promotion partner with huawei

I dont think so to be honest. Need to see what is being offered in detail lah anyway.

For d 11kWp system at rm25800, how many panels would be needed? It's bill of rm650 is ~1366kwh? My current bill is rm300, planning to get EV in 3 years time.

I dunno bro , i jz share tis ads tat popup on my fb , maybe u can PM ask them "ERS Energy" in facebook .

I think for 12kWp system x 4hrs peak sun = around 48kWp x 30days shd be for that 1400kwh usage , so their est monthly fees more or less is correct1.

If your bill is rm300, you don’t need this much. If ev is in the planning, but not confirmed, I think better not to take into consideration. Lots of thing can happen within this three years. Newer tech, cheaper options.

You most likely need about 7kwp max. If you are on single phase, you don’t need to convert to three phase for 11kwp.

Why 3 years time to get ev. Get now and enjoy. Nice ride actually.

actually very cheap. the before discount price is what i paid. Mine is 14kwp system 26panel 550w panel.

I think so .
500w panel no brand grade b around RM600 , let say 1000w each = RM1k
10kw = RM1k x 10 , RM10k
inverter let say RM5k branded 10kw system .
Total cost >RM15k add wire la , tis and tat installation + RM5k
RM20k+ for 10kwP system i think is reasonable , am i right ? I dunno i juz newbie on solar .

my house is 3 phase power, but they chose 1 phase inverter for me, it's 6.96 kw panel system, set date to install on end of May. How is it not optimized though?
