Why Switch to Solar Now
Three converging forces make 2026 the best time to make the move.
Diesel Prices Won't Drop
Global commodity prices and subsidy removal mean diesel will stay above RM6/L. Every month you delay costs more.
GITA Reduces Your Cost 60%
The Malaysian government's GITA allowance means every RM100 you invest in solar is only RM40 out of pocket. This incentive may not last.
Solar Costs Are at Historic Lows
Panel and battery prices have dropped 60% since 2020. The combination of cheap solar + expensive diesel = fastest payback in history.
