### English
* **Shift in Solar Economics:** Malaysia's transition from the Net Energy Metering (NEM) model to the Solar ATAP programme prioritizes self-consumption over one-to-one grid offsetting.
* **The Timing Gap:** Solar systems generate peak power during the day when most homes are unoccupied, creating a mismatch with high evening energy demand.
* **The Role of BESS:** Battery Energy Storage Systems (BESS) are critical for storing daytime solar energy for use during peak night-time hours, reducing reliance on the grid.
* **Strategic System Design:** Homeowners should analyze their energy consumption patterns before installation to ensure the system is tailored to their specific lifestyle rather than just roof capacity.
* **Maintenance Importance:** Regular operations and maintenance (O&M)—including cleaning and inverter checks—are essential to ensure solar systems perform at peak efficiency over time.

### 中文
* **太阳能经济模式的转变：** 马来西亚从净能量计量（NEM）模式转向 Solar ATAP 计划，将重点从一对一的电网抵消转向家庭自给自足。
* **时间错位问题：** 太阳能系统在白天产生高峰电力，但此时大多数家庭无人，导致发电时间与晚间高耗电需求不匹配。
* **储能系统（BESS）的作用：** 电池储能系统（BESS）对于存储白天生成的太阳能至关重要，以便在晚间高峰时段使用，从而减少对电网的依赖。
* **战略性系统设计：** 房主在安装前应分析能源消费模式，以确保系统设计符合其具体生活方式，而不仅仅是考虑屋顶容量。
* **维护的重要性：** 定期的运行与维护（O&M），包括清洁和逆变器检查，对于确保太阳能系统长期保持最高效率至关重要。
