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
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?
