Welcome to Celtic Green Energy’s blog, where we aim to debunk common myths surrounding renewable energy and provide valuable insights into the world of sustainable solutions. Today, we’re tackling a prevalent misconception about solar panels and shedding light on the truth behind their functionality.

Myth: Solar panels only work when it’s sunny outside

It’s a common belief that solar panels are only effective in bright, sunny conditions. However, the reality is far from this misconception. While it’s true that solar panels perform optimally in direct sunlight, they can still generate electricity on cloudy days with reduced sunlight.

Dispelling the Myth:

Solar panels harness energy not just from direct sunlight but also from diffused sunlight. Even on overcast days, solar panels can absorb sunlight across the visible light spectrum and wavelengths that penetrate through clouds. This means that solar panels continue to produce electricity, albeit at a slightly reduced rate, even when the sun is not shining brightly.

Enhancing Performance:

Contrary to popular belief, a little rain can actually benefit solar panels. Rain helps to wash away dirt and debris that may accumulate on the panels, potentially obstructing sunlight. Clean panels ensure maximum absorption of available sunlight, thus improving overall performance.

Optimising Energy Storage:

To further maximise the benefits of solar energy, Celtic Green Energy offers innovative solutions such as solar batteries. These batteries enable homeowners to store excess energy generated during peak sunlight hours for later use, such as during nighttime or periods of low sunlight. By harnessing and storing solar energy efficiently, homeowners can reduce reliance on traditional energy sources and save on utility bills.


At Celtic Green Energy, we’re committed to dispelling myths surrounding renewable energy and empowering individuals to embrace sustainable solutions. By understanding the true capabilities of solar panels and leveraging innovative technologies like solar batteries, homeowners can harness the power of the sun to fuel their homes efficiently and responsibly.
