sunspots
The full cycle, from maximum to maximum, is 11 years, so the half cycle would be about 5 1/2 years. This is a long-term average; individual cycles can be longer or shorter.
A solar farm is a power station that runs of solar energy, They're called solar farms, both with reference to wind farms, and b/c they'll have huge fields(like a regular farm) all taken up by either mirrors or solar panels.
I don't know the solar radius, but all I know is the radius and that is 25.7 R. you. :)
It really depends on the type of house and amount of solar cells. But they are usually large solar panels. People would think of big solar panels as the ones on houses but you can get bigger ones but the ones on houses would be categorised as large/big.
20% of Australians use solar power as their main enerygy source.
Sunspots
Sunspot cycles are 10 to 12 years in length.
sunspots
Solar phenomenon such as solar flares.
solar flares
solar flares
There is a solar phenomenon believed to be affected by an increase in sunspots. Most solar flares are believed to be linked to an increase in sunspots.

Solar cycles average about 11 years each. The eleven year cycle is measured by changes in the Sun's output, ejection of solar materials, sunspots, and auroras on Earth. Sometimes the cycle is referred to as a 22-year one since the sunspot activity reverses solar hemispheres (changes polarity) in alternating cycles.
Retrograde Motion
The sunspot cycle is about 11 years long. This can vary somewhat; the current cycle has had an extended minimum with very few sunspots for about 3 years, and even now the sunspot numbers are very low for this point in the cycle.
You can use solar energy at any moment, you don't have to wait until 2012. The "solar cycles" refer to cycles of sunspots; they are not very relevant to the amount of energy we receive from the Sun.
