For Malaysian SMEs and commercial facilities, managing energy costs has become a critical factor for maintaining profitability. The recent shift to the Solar ATAP 2026 policy presents both a challenge and a massive opportunity. Because the new policy operates on a “use-it-or-lose-it” credit system, simply slapping solar panels on your roof is no longer enough. To truly maximize ROI, modern businesses must align their solar generation with their operational hours, creating the perfect synergy between Solar ATAP and TNB’s Time of Use (TOU) or Enhanced Time of Use (ETOU) tariffs.
The Power of the TOU Tariff Structure
TNB’s TOU and ETOU schemes charge different rates based on the time of day. Energy consumed during “Peak” hours is significantly more expensive than during “Off-Peak” or “Mid-Peak” periods. Additionally, for medium and high-voltage commercial customers, Maximum Demand charges applied during Off-Peak periods are entirely waived. This structure incentivizes businesses to shift heavy operations to cheaper hours, but operational shifts aren’t always possible for daytime factories.
Solar ATAP 2026: The Perfect Daytime Shield
This is where Solar ATAP 2026 becomes a game-changer. Solar generation naturally peaks during the exact hours that TNB categorizes as Peak or Mid-Peak. By properly sizing your commercial solar system, you can effectively wipe out your most expensive energy consumption. Because Solar ATAP does not allow excess credits to roll over to the next month, the strategy is no longer about exporting power—it is about 100% self-consumption during premium tariff hours.

What is the TNB TOU tariff?
The Time of Use (TOU) tariff charges different rates depending on the time of day. Electricity consumed during Peak hours is more expensive, while Off-Peak hours are significantly cheaper.
Why is TOU important for commercial solar?
Solar panels generate the most power during the day, which coincides with TNB’s expensive Peak and Mid-Peak hours. This allows businesses to replace costly grid electricity with free solar energy when it matters most.
How does HOMI prevent wasted credits under Solar ATAP?
Because Solar ATAP 2026 doesn’t allow credit rollover, HOMI uses your historical energy data to size the commercial solar system precisely. We ensure the power generated matches your daytime consumption curve, eliminating waste.
