Solar cells do not require direct sunshine
Energy Saving Trust
The guide states that solar cells can work on cloudy days and that stronger sunshine produces more electricity.
Based on: Energy Saving Trust
Verdict
True
Verification confidenceHigh
Explanation
Yes. Photovoltaic solar panels can generate electricity on cloudy days. They do not require an unobstructed beam of direct sunshine to work.
The Energy Saving Trust explicitly explains that solar cells work without direct sunlight. The U.S. Department of Energy distinguishes direct sunlight from diffuse radiation scattered by the atmosphere, including clouds.
Working under clouds does not mean producing the same output as in strong sunshine. Generation depends on how much sunlight reaches the cells, so this answer does not establish a fixed cloudy-day output or guarantee enough electricity for a particular use.
Key takeaway
Clouds can reduce solar generation without stopping it. Direct sunshine is not the only usable daylight.
Evidence
Supports the claim
Sunlight includes a diffuse component
U.S. Department of Energy
The DOE distinguishes direct from diffuse solar radiation and explains that clouds scatter sunlight and can block the direct beam.

Is all stainless steel non-magnetic?
No. Several stainless steel families are strongly attracted to magnets. Other grades respond weakly, and manufacturing can change their magnetic behaviour.

Can radar satellites image Earth's surface through clouds and at night?
Yes. Synthetic aperture radar sends its own pulses and uses their echoes to form images. It can operate through clouds and without sunlight.

Does a higher-wattage light bulb always produce more light?
No. Watts measure power consumption, while lumens describe light output. A more efficient bulb can produce the same amount of light using fewer watts.
