什么是 SelCo？
SelCo（Self-Consumption，即“自发自用”）是一种不依赖政府补贴、不需将电力卖回电网的太阳能使用方式。系统所产生的电，优先供自家使用，多余的电量不会回售，也不会产生额外收益，但用户可透过减少向 TNB 购电，间接达到节省电费的效果。
SelCo, or Self-Consumption, allows you to use the electricity generated by your solar panels directly, without feeding it back into the grid. You won’t earn from surplus power, but you’ll save by reducing the amount of electricity purchased from TNB. It’s a simpler, incentive-free solar model.
SelCo 与 NEM 的差别
| 项目 | NEM | SelCo |
|---|---|---|
| 是否需政府配额 | 是 | 否 |
| 多余电力处置 | 回售至电网，换取电费回扣 | 不外送，自用或浪费 |
| 合约机制 | 需注册并获批准，配额有限 | 无需注册，随时可实施 |
| 收益模式 | 可获得账单扣减，通常回本期较短 | 透过节省支出达到效益 |
Difference Between NEM and SelCo
| Category | NEM | SelCo |
|---|---|---|
| Government quota | Required | Not required |
| Excess power | Sold to grid for credit | Not exported; used or wasted |
| Registration | Needs approval and quota availability | No approval needed |
| Benefit model | Earn rebates on your bill | Save by reducing purchased electricity |
谁适合选择 SelCo？
**- 没赶上 NEM 配额但仍希望节省电费者
用电量大，日间用电集中者（例如白天在家的家庭主妇、远程工作者）
希望系统独立运行、不依赖电网机制者
未来仍可能转为 NEM 或其他计划者（系统可保留并升级）**
Who Should Consider SelCo?Those who missed NEM quotas but want to reduce bills
Households with high daytime energy usage
Users who prefer off-grid or independent systems
Those planning to upgrade if future incentives arise
安装前的注意事项
**虽然 SelCo 没有政府流程，但仍需注意以下事项：
系统设计要贴合用电曲线，避免发电浪费
系统容量建议控制在每日实际用电量范围内
搭配储能设备（电池）可提高使用率
建议使用智能监测系统，以便实时调整负载与节能行为**
Installation Tips for SelCo UsersMatch system size with your typical daily usage
Avoid oversizing to prevent energy loss
Consider adding battery storage for better efficiency
Use smart monitoring tools to track and optimize performance
总结：错过NEM不是终点
NEM不是唯一通往太阳能节省的道路。透过SelCo，用户依然可以享有长期稳定的节能成效与电费下降。关键在于精准设计系统与了解自身用电需求，选择适合自己的太阳能策略。
Conclusion: NEM isn’t the only way to save.
With SelCo, households can still enjoy significant long-term savings. The key is having a well-designed system tailored to your needs—and understanding that solar remains a valuable energy solution, even without incentives.
