Illustrative scenario — not a Trexon project. Manufacturing margins are tight. This worked example shows how a factory in Shah Alam could think about a 420 kWp rooftop system. The factory and the figures below are hypothetical and are not a Trexon installation.

The Challenge (hypothetical)

  • Bill: about RM 55,000 / month on a TNB medium voltage tariff
  • Issue: a large daytime load and any monthly AFA adjustment that applies to the account.

The Solution (hypothetical)

A 420 kWp rooftop system sized to the factory's daytime load.
Funding routes Trexon offers: outright purchase or, for businesses, hire purchase through Mitsubishi HC Capital Malaysia. Commercial projects start with a booking of 20% of the system price, capped at RM20,000, credited in full to the system price. Trexon does not offer a PPA.

The Results (estimate only)

  • System yield: about 44,000 kWh / month (420 kWp x 3.5 peak sun hours x 30 days)
  • Savings: depend on the factory's tariff, load profile and how much of the output it uses on site. We do not quote a figure for this scenario. Request a free quote for numbers based on your own bills.
