阴天≠无法发电
只要白天有光，哪怕阳光被云层遮住，太阳能板仍然可以透过散射光发电。低光环境下的输出虽然会下降，但仍具实际价值，特别是配合智能电力分配系统时，可有效降低家庭用电开销。
Cloudy skies don’t stop solar production. As long as daylight is present, even diffused sunlight can be converted into electricity. Output may drop, but modern energy management systems can optimize usage, reducing household electricity bills.
不同天气下的发电效率
| 天气状况 | 发电效率估算（相对于晴天） |
|---|---|
| 晴朗无云 | 约 100% |
| 多云或局部遮蔽 | 约 40%–60% |
| 阴天或下雨 | 约 10%–30% |
Solar Output by Weather Type
| Condition | Estimated Output vs. Sunny Day |
|---|---|
| Clear and Sunny | ~100% |
| Partly Cloudy | ~40%–60% |
| Overcast or Rainy | ~10%–30% |
为什么仍然值得装？
1. 马来西亚年均日照天数超过250天，阴雨天气不占多数
2. 高温与直射阳光未必代表发电效能最佳，温度越高可能影响面板效率
3. 即使阴天产能降低，也能长期拉高累计产出，提升投资回报率
Why Solar Is Still Worth It
Malaysia enjoys over 250 sunny days annually
Cooler, diffused light can sometimes improve panel performance
Even on cloudy days, cumulative output adds up over time
技术演进降低气候影响
现代太阳能系统采用单晶PERC技术与低光启动逆变器，具备快速响应与稳定输出特性。系统还能根据光照自动调整电力调配方式，提升整体系统效率。
Advancements like mono PERC panels and low-light inverters ensure modern systems respond quickly and operate reliably. Smart solar systems also optimize internal power flow to boost total efficiency regardless of weather.
总结：不用等好天气
阴天不是障碍，误解才是。与其等“天气变好再装”，不如提早建置、累积效益。技术已进步到让太阳能全年运作，马来西亚的气候仍是极具优势的投资场景。
Conclusion: Stop Waiting for Perfect Weather
Clouds are not the problem—misconceptions are. Rather than waiting for ideal conditions, it’s better to install early and start saving. Malaysia’s climate remains highly favorable for solar investment year-round.
