What does maintenance cover?
*
solar panel cleaning.
cable connectivity checking.
cleaning tools.

so its rm500 each year.

My usage is about rm200 every month on the dot.

investment is 22k installation everything all in. The Nem program is only 10 years after that i cant feed back into the grid.

Since most power is use at night when 2 ac is turn on 1hp and 1.5hp

Rest during the daytime are just DC fans ceiling n standing fan .

Some say bills that hit 400-600 is only worth it but salesman say 200 can save 90% and expect to pay rm10 a month.

sorry i just kay poh abit

your usage is RM210pm
if you use solar,...you save = 210pm
maintenance fees RM500 pa = 40pm
210 - 40 = 170 saving....

assuming 15 years = 170 x 12 x 15 = 30 600

you pay 22 000, thus you gained 8600 in 15 years....abt RM 573 pa

hmm.gif what is the ROI pa for this 22k?

22k @ 3% pa FD = RM 660 pa

what is the solar replacement cost like batteries and other electronic parts/apparatus???
what are the service life of electronic parts in electrical apparatus?
how much can you sell back the extra power for 10 years?

oips sorry im not being very clear here.

I was quoted so far. I have yet to decide on installing this solar system.

Another SP just quoted a 2kwp system. with cheaper maintenance cost of 250 a year.

I had to put into consideration that NEM is only 10 years. After that im all alone . If i sign this up

This NEM is mean you sell back the unused electricity back to Govt?
if yes, have you checked,..how much $$ can you get per month if you/when you sell the (NEM) with you current set up?

thumbup.gif 190 pm is a nice number...
if can sell 190 x 12mth x 10yrs = 22800
during this 10 years or after the 10 years,...
what are the replacement cost?
any things need to replace/repair?

from initial investment of 22k, it gets 22k "sales" in 10 yrs
from rule of 72, it is abt 7.2% pa ROI
with just 7.2% pa ROI, based on the "said RM190pm" of the sales man, the possible replacement/repair cost....and the depreciating cost of the initial items purchased of RM22k....(cannot sell 3k after 10 yrs)(just like car?)

i think i will put this in EPF....no depreciating cost (except MYR) and compounded returns on that RM22k

i think no need maintenance cost. but sometimes got issues if rats bite the wire, lightning strike the panel etc. if you are comfortable with technical, and can get >10%, i think can consider.

EPF now adays about 5 to 6%.

i think,...EPF no depreciating cost...the 22k in EPF never depreciate (except MYR)
there should be depreciating costs of the 22k solar equipment system and that 22k solar system cannot last forever....as it has many components

depends if he does calculation properly.....

- if he uses IRR calculation, initial upfront and terminal value already factored in
- if he uses simple yield calculation, then you are right.

on the solar panel, he didn't answer my question of panel / inverter brand. panel usually 25 to 30 years can tahan for grade 1. inverter maybe 8 to 12 years.

solar system also a hedge against rising electricity price. RM depreciating, should see fossil fuel price increasing and result in higher electricity price. Have been happening for long time.

so, more complex a bit.....but if he don't provide full details, then we cerita cerita only lah tongue.gif

thumbup.gif yes, for cerita cerita only....

solar invertor replacement is 8~12 years will cost $$

i foresee lower fossil fuel prices as more and more EV car on the roads....many countries had set target for full adoption of new EV cars.

yes, more complex,...for he need to do the calculation properly,...not just by the word of the salesman.
don't just focus on "can get back the investment in 10 yrs...."

during.

i cant foresee any replacement parts etc. but i think the inverter will die first. looking in this thread some got quoted by their sp at 8k each inverter.

shopee taobao has em like less than 2k of coz you support your ownself

Panel
BNEF 1
st Tier Panel: Seraphim Series III 440W

Inverter
GoodWe
: GW2000 NS

how are these? these are the quote of 22k system

I just had another quote of 17k but paying using cash or bank transfer.

this one uses canadian solar and fronius inverter

What is the best quote in RM you got per kW/p for a 4kWp system? Anyone got less than RM16K for a 4kWp system?

What components (panels and inverters) used?

Based on your current usage, it's not worth it for solar. As our electricity is billed on a tiered level, the higher your usage, the more expensive it becomes. And with NEM, the excess power generated is offset against the top tier and downwards. Hence, if you monthly bill is >RM600, your returns are reasonable to go with solar.

You can actually skip the yearly cleaning part, to be frank Malaysia thunderstorms are good enough to give it a good wash and on the flip side, your panels will get "dirty" again after few days post cleaning so no point.

Cables part, you can request for the expose cable to be in trunking during installation ; this will reduce the risk of damage / aging due to UV . Anyway, the solar DC cables are rated for such outdoor conditions.

Solar is pretty much a maintenance free system, until something fails (which typically will be the inverter after ~8 to 10 years).
