☁️ Myth: Solar panels don’t work on cloudy days.
✅ Fact: Solar panels still generate power even when it’s cloudy or raining.
💰 Myth: Solar is too expensive.
✅ Fact: Prices have dropped, and most systems pay for themselves in 5–7 years.
🏠 Myth: Only houses with big roofs can install solar.
✅ Fact: Even small roofs can accommodate efficient solar systems.
🔧 Myth: Solar panels require a lot of maintenance.
✅ Fact: They are low maintenance, requiring only occasional cleaning.
⚡ Myth: You won’t have power at night.
✅ Fact: Homes still use grid electricity at night, but can sell excess solar power during the day.
Myth #1: Solar Panels Don’t Work on Cloudy or Rainy Days
Reality: Solar panels still generate electricity even when it’s cloudy, overcast, or raining.
Singapore’s tropical climate includes both sunshine and frequent rain, but solar panels don’t need direct sunlight to work. They generate electricity from daylight, meaning even cloudy conditions provide enough light for energy production.
How it works:
- Cloudy weather: Solar panels operate at about 70–80% efficiency under cloud cover.
- Rain: Helps wash away dirt and dust, improving panel efficiency.
Conclusion: Solar panels are still effective year-round in Singapore’s climate.
Myth #2: Solar Panels Are Too Expensive
Reality: Solar prices have dropped significantly, and the system pays for itself in 5–7 years.
Many homeowners assume solar energy requires a huge upfront investment, but the cost of solar systems has fallen by over 70% in the past decade.
Cost Breakdown in 2025:
- A typical 5 kWp system costs around S$20,000 – S$25,000.
- Monthly electricity bill savings: S$250 – S$350.
- Payback period: 5 to 7 years.
- After that, your energy is essentially free for the next 20+ years.
Additionally, Singapore’s Sell-to-Grid scheme allows homeowners to sell excess solar energy back to the power grid, further reducing costs.
Conclusion: Solar is a cost-effective investment that saves money in the long run.
Myth #3: You Need a Big Roof for Solar to Work
Reality: Even small roofs can support efficient solar systems.
While larger roofs can fit more solar panels, you don’t need a massive space to install a system.
Why?
- Solar panels are more efficient than ever, meaning fewer panels generate more energy.
- Systems can be customized based on your roof size and energy needs.
- You can even install east- or west-facing panels to maximize energy production throughout the day.
Conclusion: Whether you have a small terrace house or a larger landed home, there’s a solar solution for your roof.
Myth #4: Solar Panels Require a Lot of Maintenance
Reality: Solar panels are low maintenance and require only occasional cleaning.
One of the biggest myths is that solar panels are troublesome to maintain, but they actually have no moving parts, meaning there’s little risk of mechanical failure.
Maintenance requirements:
- Rain naturally washes away dust and dirt.
- A quick clean every 6–12 months keeps them running at peak efficiency.
- Most systems include monitoring apps, so you can check performance in real time.
Most solar providers also offer long-term warranties (20–25 years), ensuring panels perform optimally for decades.
Conclusion: Solar panels are hassle-free and require little effort to maintain. To read more about it, we cover the maintenance in the article here: Solar Panel Maintenance: Keep Your System Running at Peak Performance
Myth #5: You Won’t Have Electricity at Night
Reality: Homes use grid electricity at night, but daytime solar production offsets costs.
Since solar panels generate electricity only during the day, some people worry about power supply at night. However, in Singapore, residential solar systems are grid-tied, meaning:
How it works:
- During the day, your panels generate electricity.
- Excess energy is exported to the grid.
- At night, you use grid electricity, but your energy bill is much lower.
Some homeowners choose to install battery storage to keep excess energy for night use, but this is optional.
Conclusion: Solar homes always have electricity, and the grid serves as a reliable backup.
Now that we’ve debunked these common myths, it’s clear that solar energy is a smart, reliable, and cost-saving investment.
Why homeowners are switching to solar:
- Saves money on electricity bills.
- Works in all weather conditions (even on cloudy days).
- Minimal maintenance required.
- Sell excess power back to the grid.
- Increases property value.
If you’re considering installing solar panels, now is the time to take action. Prices are more affordable than ever, and the long-term benefits make it a wise investment.
FAQ: Your Solar Questions Answered
1. Are solar panels still worth it without government subsidies?
Yes! Despite the lack of direct subsidies, lower solar prices, Sell-to-Grid schemes, and long-term savings make solar a great financial decision.
2. Will solar work if my roof isn’t south-facing?
Yes! East and West facing panels can still generate plenty of energy.
3. How long does it take to install a solar system?
Most residential installations take 3 - 8 days, with minimal disruption.
4. How do I know if my home is suitable for solar?
A solar provider can conduct a free assessment to check your roof size, angle, and energy needs.
5. Can I sell my extra solar energy back to the grid?
Yes! Under Singapore’s Sell-to-Grid scheme, you can earn credits by exporting surplus energy.
