Hi guys, couldn't find much info about NEM 3.0. Have anyone tried before? Is the initial investment worth it?

Sorry, not referring to the cryptocurrency. TNB's Net Energy Metering 3.0.

Recently, electricity bill is getting higher. Am considering installing solar system but not sure if it's worth it.

Would be great to hear some feedback from those already installed.

Thanks

My bad.. I delete previous post

I have been looking into solar for my house and got quoted under this new scheme. The 10 year limit on NEM seems to be a deal breaker. By the time the solar system investment is recovered by savings, the NEM period is almost over and you're stuck on using what you produce. If you're using a lot of power during the day time, that might be fine, but many would be using more at night with aircon and more people being at home then. Otherwise if you have a really high electric bill, the reduction of cost in the higher tariff rates while under NEM will decrease the investment payback period, so sure there might be a few years where you're ahead.

but we can install/buy battery after 10years when the NEM contract ended

Yeah that's probably going to cost a fortune unless there's some cool new tech out by then which cuts costs. The company that quoted me said with battery costs would almost be as much as the price of the initial system. I'm sure the longevity of the batteries is much less than the solar, plus solar panels degrade over time and have a lifespan of 25-30 years typically.

At the end of ten years, to renew contract with TNB if can, else get ready battery. By 10 years time, the battery price shouldn't be as expensive as now. New tech and better material will bring down cost, hopefully la.

May I know which NEM 3.0 purchase mode are you considering? Outright purchase or leasing?

Are you supplying? May I know what's the difference?

Maybe it will, but if it doesn't you are barely breaking even on your system at the 10 year mark and what it produces goes to waste if you don't use it at that point. Not very green energy if any excess is just getting thrown away.

My breakeven ROI is 5 years only..... anything after that is bonus. Already used 6 months, pretty up to my ROI mark. Where did you learn about the barely 10 years mark?

the short answer is : It actually depends on your mthly electricity consumption, if ur mthly TNB bill is below RM120 then its confirm not worth it!
Did some calculations few yrs back..... they keep saying set up cost going down bla bla bla.... its still hovering 30K to 50K (pls also include maintenance yah)

IMHO, how many household in malaysia will use electricity until RM500 to RM800 per mth? lol.... if ur using this much electricity then faster go install and splurge ur moolah .... but ur ROI also need to wait a few yrs to get back....

Also its only worth it if TNB pays u back ur surplus energy.... if not mistaken the first batch of NEM application in MAlaysia got the best deal..... unfortunately no more alredi......

Calculations based on corrected values of what quotes I've gotten. My electric bill isn't too high and the proposals companies are doing for nem 3 try to provide as close to 100% of usage. For people with high bills and a system that reduces the higher tariff rate kw usage, then break even would need more reasonable.

So far for 6 months, my solar generated power exceeded the projected tariff savings by the solar company. I am glad I signed up for this NEM system.

Could you share to company that did your installation?
Can you share your installation specifications? How. Much was projected and how much you're generating? I'm very keen to install but have doubts on how much the actual generation?

Brudder please contact any NEM solar system provider, let them enlightened you better.

I have gotten a few quotes and each have explained to me but what I'm looking for is experience from real users not salesman. I would like to know how many kwp is your installation and how much you're actually generating and does it match what they sold you also if you could share the company which did it and how happy are you with the work they have done.

You mean battery is not included in the quotation? This will be of limited use as most household electricity is used at night. Have you tried to calculate the breakeven period with battery?

Saves more than what they have projected, so far I know of other users also with similar experiences, the brand doesn't matter.
