TNB Bill No. 1: Pre Solar Installation
Ms. H’s TNB Bill – August 2020
Under the billing period (Tempoh Bil) section, we can see their billing summary.
(A) – Energy consumption (Kegunaan (kWh/kW) for the month.
(B) – Prices set by TNB (blok tarif) how much the energy consumption amounts to.
(C) – How much a home-owner is charged. Calculation = TNB (blok tarif) prices + service charge (6%) + KTWBB (1.6%). In this case, RM 680.49 is the total bill for energy consumption of that month (Caj Semasa).
TNB Bill No. 2: Post Solar Installation
Ms. H’s TNB Bill – April 2021
(A) – Customer imported/used 1,073 kWh (Blok Prorata) = RM494.38
RM494.38 + Service tax charge (6%) + KWTHBB (1.6%) = RM 496.02 (Jumlah Import).
(B) – Customer exported 748 kWh of electricity to the TNB grid = RM 404.48.
(C) – Customer TNB bill = RM 91.54 (Jumlah Caj Bersih)
RM 496.02 – RM 404.48 = RM 91.54
The customer saved 86.55% for the month.
In addition to this, if the amount of energy exported is more than the amount of energy imported from the TNB grid, the excess credit will be applied to the next month. For example:
According to this bill, the excess energy exported is 214 kWh. It does not amount to anything in this bill, however will be used to reduce the total in the next month. This applies to every solar-powered homeowner.
