Methodology: Solar irradiance 4.5 to 5.3 peak sun hours/day by state. Performance ratio 78%. Panel degradation 0.5%/year. Self-consumption based on occupancy (WFH 65%, mixed 50%, office worker 30%, rarely home 15%). Export credit is a bill offset under Solar ATAP, not a cash payment. Export discounted 20% for policy risk over the calculation period. TNB tariff inflation 1.5%/year (conservative, applied to base savings then recapped at inflated bill). Inverter replacement at year 12 at 25% of installation cost. ASB/EPF opportunity cost at 5.5% compound annual return. SuRIA Home rebate RM600/kWac capped at RM3,000. Installation costs RM3,800 to RM4,200/kWp (2026 market rates). All figures are indicative estimates. Get real quotes from SEDA-registered installers before deciding.
