Configure solar11.78 kWp Solar System
Turn your roof into a power plant. Perfect for homes with RM 590 - 670 monthly bills.
An 11.78 kWp solar system in Malaysia uses 19 panels covering roughly 48-57 sqm of roof area, and is built to suit homes with a RM 590 - 670 monthly TNB bill. Trexon installs it from RM27,999 with a Solis, Huawei, or Sungrow inverter, Tier-1 panels, mounting, installation, SEDA submission, and TNB commissioning included, all backed by a 30-year panel performance warranty. Once commissioned, the system saves around RM 450 per month through a mix of reduced TNB grid consumption and Solar ATAP export credits, paying back the installation cost in roughly 5.2 years. The price and inverter brand shown update live as you compare Solis, Huawei, and Sungrow below, and every figure ties back to the same size-specific specification — not a generic estimate.
