Solar Savings Calculator Malaysia

Within about 10 to 15 per cent, because it assumes an average roof. It uses Malaysian irradiance data, current Solar ATAP rates and the bill you typed. Send your actual bill and the estimate is replaced by a quote built on your real usage; book the RM100 priority visit and your roof, shading and wiring are confirmed in person, with the full RM100 credited to your Trexon project when you proceed.

As a guide: RM200–300 → 5.58 kWp. RM300–500 → 6.82 kWp. RM500–800 → 10.54 kWp. RM800+ → 11.78 kWp. The calculator above sizes it exactly for your typed bill.

Between about 4.4 and 8.2 years for most homes, paying cash — larger systems tend to pay back faster because installed cost per kWp falls as size increases. Financing spreads the cost but extends the payback because of interest. After payback, the panels keep producing for the remaining years of the 25-year warranty.

Between about RM 2,380 and RM 3,490 per kWp installed, including panels, inverter, mounting, installation and Solar ATAP registration. Bigger systems cost less per kWp — around RM 3,490 at 5.58 kWp, around RM 2,380 at 11.78 kWp.

No. The quote itself is free and there is no obligation. The only thing we ask for is your latest TNB bill, because without it we are guessing at your usage and so is the price.
