http://seda.gov.my/After reading from Seda website, the FIT rate has been on down trend for the past 3 years, from 2012's rm1.78, 2013's rm1.6408 and 2014's rm1.5128. This rate is the 4KW system
Can I conclude that every year it will reduced by rm0.10?
To set up a 4KW system we need to borrow(or use cash) of rm40000 with interest rate of 6% PA. Loan for 3 years, rm7200.
As per advertised, I can get average of rm600 per month(assuming that the price of FIT never drop but actual is dropping), so 21*12*600=rm151200
Taking the actual calculation, for a 4KW system, this year 384*1.5128=rm581(6972)-588
last year will be 384*1.6408=rm630(7560)-642
2012 is 384*1.78=rm684(8202)
Another wild conclusion, every year income will be rm500 less.
So, for a 21 years of contract, I'm getting rm69040 only. Considering the investment I made, borrow rm40000 with interest of rm7200, so rm69040-rm7200=rm29040.
rm29040 of ROI over 21 years will be rm1382 a year of gain. So 3.44%.
This is assuming that the solar panel will be 100% efficient and I no need to change the solar panel and the inverter.
Again, in actual this won't be happening and I do need to change the inverter and service the solar panels. If each time change and service is every 5 years(actual servicing solar panel is 2-3 years depending on the generation), I need to do it for 4 times. And if each time cost me rm1000, I will have to deduct another rm4000 from 29040. So actual ROI will be only 2.5%.
Just roughly share only, in actual Seda will penalty us if we do not generate enough power as per the contract.
