Solar Panel for RM300 TNB Bill

For a RM300/month TNB bill, a 5.58kWp solar system starts from RM15,999 with Solis, while the Huawei Premium option is RM18,999. Both include panels, inverter, mounting, wiring, and full Solar ATAP certified installation.

For a RM300/month TNB bill, you need approximately 9 Jinko 620 W N-Type solar panels, forming a 5.58kWp system. The exact count depends on your roof orientation, shading, and daily consumption pattern. Send your bill and a few roof photos for a free quote with the exact layout.

With a RM300/month bill and estimated savings of about RM184/month, a 5.58kWp system from RM15,999 (Solis) pays back in about 7.2 years, or about 8.6 years with Huawei (RM18,999). Over 25 years the estimated saving is about RM44,760 — export credit counted for the 10-year Solar ATAP term only, self-use savings after that.

On overcast days output is reduced; heavy rain can cut it by an estimated 20–60%. At night, your home draws from TNB as usual. Under the Solar ATAP scheme, surplus daytime generation exported to the grid earns a bill credit at the Energy Charge, up to that month's import; any surplus beyond it is forfeited monthly.
