Solar Year (7) Review 2022

 Solar Year (6) Review 2022

Energy Efficiency whole year produce energy as record below,

Year Generated(Kwh) TNB Quota(Kwh) Generated Vs TNB Quota,%

2016     10227      10327      99.03%

2017     8883        10275      86.45%

2018     9210        10220      90.12%

2019     6559        10170      64.49%

Payment wise no issue every month payment consider on time. payment made at mid of the month after invoice received. ROI To verify on the ROI as below. up to year 6 recover 75% 

remaining 25% will cover back the cost, remaining will be earning. 

Estimate another 2 years to fully recover, with each year 14 to 15% ROI.

Year 5 efficiency drop and require replacement of invertor and maintenance, due MCO only completed the invertor pending maintenance on solar panel. cost RM 8,200 for this maintenance.

Year 6 - did not manage to do solar panel clean up. plan to do in year 7 but not sure how much efficiency will be boost up.

Year 7 - no action done. solar stay as it is, breakeven will happen in year 8, defer 1 year as expected due to break down invertor in year 5.
