Malaysia pays a business a bulk rate for leftover lunchtime sun. That is not the rate on your bill.
Malaysia’s workplace solar rule has a name: Solar ATAP. Use the power in the building first. Leftover energy can go to the public grid as a bill credit. The credit rule splits on who you are on the bill.
Think of a factory at noon. The roof is making more power than the machines are using. That leftover can go out to the grid — like pouring spare milk back into the dairy’s tank — and come back as a credit. The published idea is simple: drink your own milk first.
For a business, that credit is called Average SMP — the bulk price the system pays for leftover power, not “whatever you usually pay the power company at 3pm”. A house sits on a different credit, tied to the home bill. Finance cares which side of that split you are on.
Good: a workplace on Peninsular Malaysia can put surplus noon on the grid and take a credit.
Bad: the credit is a bulk number. It is usually thinner than the rate you avoid by using the power yourself.
Ugly: a factory, warehouse, or office that still uses power after sunset is giving away the useful hour every time leftover noon leaves the site. The guideline does not publish a payback that fits every site. Anyone who does is guessing when your machines run.
Start with when the building actually uses power, and what the main board can take — the big fuse room, not a photo of the roof. Panels without that conversation are a noon hobby.
