阴天太阳能还有用吗?在马来西亚安装太阳能依然值得吗? Can Solar Panels Still Work on Cloudy Days? Why Going Solar Is Still Worth It in Malaysia

阴天也能发电

太阳能板并不依赖强烈阳光,而是能利用散射光发电。只要白天有光线,即使是被云层遮蔽的阳光,系统依然可以正常运行。现代太阳能技术已具备低光照环境下的运作能力,即便天气不佳,也能维持一定的发电输出。
Solar panels don’t require direct sunlight to function. They can generate power using diffused sunlight, which is still available even on cloudy days. Modern solar technology is designed to operate efficiently in low-light conditions, maintaining electricity output even during poor weather.


发电效率差异

根据气象与技术数据统计,不同天气状况下的发电效率大致如下:
晴天:约为额定输出的 100%
多云:约为 40% 至 60%
阴天或雨天:约为 10% 至 30%

Data shows approximate energy production as follows:
Sunny: Around 100% of rated output
Partly Cloudy: Around 40% to 60%
Cloudy or Rainy: Around 10% to 30%


技术让系统更稳定

HOMI 所采用的太阳能系统具备单晶硅板(Mono PERC)和具备低照启动能力的逆变器,能在光照较弱的情况下正常运作。同时,系统具备智能追踪功能,可自动调整参数以优化全天发电效率。
HOMI’s solar systems use Mono PERC panels and inverters that start up under low-irradiance conditions. Intelligent monitoring systems continuously adjust system parameters to maintain optimal performance throughout the day.


长期效益依然显著

对于家庭用户而言,太阳能可有效降低每月电费,长期平均节省超过 70%。若结合净电量回馈计划(NEM),还能将多余电力回售至电网。
对于企业用户,太阳能不仅节省营运成本,还能提升企业形象和 ESG 评分,有助于永续发展目标。

For households, solar energy significantly reduces monthly utility costs—on average by over 70% in the long term. With the Net Energy Metering (NEM) program, users can sell excess energy back to the grid.
For businesses, solar not only lowers operating expenses but also enhances corporate image and ESG scores, contributing to sustainability goals.


安装效益取决于执行团队

太阳能系统的效益不仅取决于设备性能,更仰赖系统规划与安装质量。建议选择经验丰富、提供完整服务流程的团队,例如 HOMI,从评估、设计、补助申请到售后监控,一站式完成,提高发电稳定性与使用寿命。
The effectiveness of a solar system depends not only on the equipment but also on how well it is planned and installed. It’s advisable to work with experienced providers like HOMI, who offer full-service support from assessment, design, subsidy applications, to post-installation monitoring, ensuring long-term efficiency and durability.
