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.

A cold storage facility on Pulau Indah Island installed 450 kWp, the largest single rooftop system in their logistics cluster, generating 1.24 million kWh annually. Annual TNB savings of RM 875,900 directly offset the enormous refrigeration electricity draw. The RM 999,000 GITA deduction and a BNM Green Technology Financing Scheme (GTFS) loan at 3.5% enabled the project with minimal equity outlay, achieving full payback in 3.5 years.
