The amount of magnetic flux that rises up to the Sun's surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is sometimes referred to as the sunspot cycle.
The solar magnetic cycle is driven by the magnetic flux.
It depends on the size of the star forming. For a one solar-mass star it lasts about 1,000,000 years.
Earth is the only one known, and certainly the only one in our solar system.
too long , because a payment cycle is one day two max.
One complete cycle every 28 days.
Actually the 8 minute long solar eclipse was a world record for the longest one therefore solar eclipses are not usually 8 minutes long.
The nitrogen cycle
The most obvious solar cycle the sunspot cycle, of roughly 11 years (on average - the length of an actual cycle may vary). Once in every sunspot cycle, the Sun's magnetic field reverses (north become south, and south becomes north), so a full cycle (for north to be back where it started) is twice the sunspot cycle.
Solar max (aka solar maximum) refers to period of greatest activity during the solar cycle of the Sun.
A few variables are involved like, does the solar panel have a charge controller, what condition the battery is before you start and how much sun is the solar panel receiving.
Scientists estimate that it can take a single water molecule as long as 4000 years to complete one cycle.
One minute is 60 seconds, one hour is 3600 seconds.
