is trinasolar 0.495kw sounds older gen ? Is it bifacial ?

ya based on the product code it is monofacial ..

do they suggest 12 pcs x 0.495 to get your 5.94kWp system?

if you believe you have potential to increase higher usage in future and your roof has limited spaces, try to get some quotations who can offer highest capacity Panels so that you can leave some spaces on your roof for future expansion.

cheers

yeah, that's what my thought is too.

for mine , it is 'Max Continuous Input Current' 4x16A d.c.

TNB revised the Jan Bill least 2-3 times, make sure you are getting the 'latest' Jan bill.

10 years guys, who are we to predict what would happen after 10 years time..

I think however small a system it would also be able to save the bill in the 10 years tenure. What is usually not considered is the potential maintenance cost. For eg. fixing an out of warranty panel for a small system like this 4.64kWP is the same as a big system (>10kWh), but this extra cost adds up significant ROI period to a smaller system.

use 'estimated', not 'expected' because there are other unknown factors. Estimation uses either 3 sun hour or 3.5 sun hours per day X 30 days a month. ie. 6kWp x 3 = 18kWp x 30 = monthly generation estimation

That's what I was given when I started looking for quotes.

Simple supply & demand i guess. As there are more and more install base, i'm sure there will be some kind of 3rd party contractors who are willing to panjat for you. So long as u willing to folk out $$$ i'm sure there is always someone who can assist.

Agree that generally south would receive more.. you can see where the sun is positioned from Mar - Aug and from Sept - Feb, sun path is slightly different on each period. Ie. my car porch (facing NW312') receive marginally more sunshine during afternoon in Mar - Aug, so overall the north panels aren't as productive as the one facing sourth.

Sunpath in MY for now.

Actually after the panels are installed, i feel it is cooler staying in the upper floor at noon than before....

try estimator online ie. https://services.seda.gov.my/nemcalculator/#/

if you live around klang valley, would be good to visit Homedec at KLCC .. many special promos.

i would suggest you filter out a few and then Google around some comments and experienced shared by others.. the worst scenario i have seen was installation delayed for some unacceptable reasons.. Go to FB there are quite a few Solar discussion groups where you get to read more experience sharing. I went to the famous P* but then i had a very bad experience with their installation process.. So, not everyone is perfect especially when you are getting a 'lemon' service provider.

true also, luck plays some roles.. but background check should help in filtering out a real bad one.

Does sound like a 7.xxkWp package ... Maybe double check again? If it is truly 22k/23k for 8.64kWp it is a steal! Also, in general micro cannot be cheaper than String ...

i seriously think there should not be that much of a difference, some caveats lying somewhere .. or else u should really give your pg sales some -ve feedback jor...

Does anyone know the RM/kWh before the Solaris time ?

would be nice if existing customer can share a copy of the policy statement to see what are the T&C in details...
