Each time the Sun forward onto land in 1367 watts per . Taking into account the fact that Earth is a sphere (and therefore the rays often angled) which also rotates, the solar radiation upon Earth's surface on average 24 hours and four Seasons at European latitudes of about 200 watts per square metre.
When our sun shines onto land, it can exert up to 1367 watts per square meter. Taking into account the fact that Earth is a sphere (and therefore the rays often angled), and also rotates, the solar radiation upon Earth's surface on average, over 24 hours and four seasons, at Europe's latitudes, is around 200 watts per square meter.


The amount of solar energy arriving on Earth's soil is so huge, about a thousand times greater than all the energy used by humanity as a whole, but scattered in the sense that it is necessary to collect energy from vast areas in order to have significant quantities, and rather difficult to convert into easily exploitable energy (mainly electricity) with acceptable efficiencies.

Also, it is rather difficult to convert that energy into an easily exploitable form (mainly electricity) with acceptable efficiencies.
 
To exploit it, products are needed which are generally high in cost, which make solar energy much more expensive than other methods of generating energy.
