Pro Tip 1/3Scientific Term
Used mainly in scientific or technical contexts, such as physics, geography, and environmental studies.
Researchers compared the irradiance levels across different ecosystems.
Pro Tip 2/3Measurement Unit
Often used with units of measurement, especially watts per square meter, to specify energy amount.
The solar panel's efficiency depends on the irradiance, usually in the range of 1000 W/m².
Pro Tip 3/3Context Specific
Understanding the context is crucial. For example, 'solar irradiance' relates to sunlight, while 'spectral irradiance' pertains to specific wavelengths.
The spectral irradiance can tell us which wavelengths are most intense during midday.

Video examples
Why aren't we only using...
to generate solar power. In solar panels, photons from the sun's rays hit the surface of a panel, and electrons are released to get an electric current going. Solar panels can use all types of irradiance, while solar towers can only use direct irradiance, and this is where clouds become important
Video examples
Generating Power on Mars...
ways one we can use all ourselves we have very thin sheet solar panels that we can create now that are very light that's just like a thin sheet of plastic but solar energy on Mars is a bit thin Mars is solar irradiance is about half
