How to use these planning scenarios
Each scenario starts from a household's monthly kWh use and shows a modelled system size, bill before and after, and payback. They are illustrations produced by our estimating engine, not Trexon customer projects, so no scenario is a promise of what your own system will save.
To find the scenario closest to you, compare your average monthly usage and roof type with the scenario titles, then look at the system size. Our catalogue prices run from RM15,999 for 5.58 kWp up to RM40,499, and the right size follows your daytime consumption.
Savings shown assume Solar ATAP, where exported energy is credited at the programme rate and any unused export credit is forfeited each month. That is why systems are sized to be used on site rather than exported. For your own figure, send your TNB bill and request a site-specific assessment. The RM2,000 booking is non-refundable and credited to your system price. Trexon does not offer PPAs, and our warranty is 30 years panel performance, 12 years product, 10 years inverter and 5 years workmanship.
