Maximum Demand (MD) charges on your TNB bill are calculated from your single highest 30-minute kW draw each month. Solar offsets peak daytime loads directly, cutting MD charges 15–30% in addition to energy savings.
TNB's C2 commercial tariff reached 45.62 sen/kWh in January 2025. Each tariff hike compounds your operating cost. Solar locks your electricity rate at near-zero for 25 years — the only permanent hedge against future increases.
Malaysia's Green Investment Tax Allowance lets you deduct 60% of the full solar capital cost from statutory income. For a RM 800K system, that's RM 480K off your tax bill — disappears entirely if you miss the December 2026 deadline.
