what's the measure of sun energy?

Answer 1

Because the sun emits different kinds of energy it depends on what type of energy your measuring.
The sun emits light energy, magnetic energy, and radiation energy. Light is measured in lumen's.
radiation is measured in rems or milirems or rads, and magnetic energy is measured by some other method I don't know.

Answer 2

There are a number of different measures. The Sun's energy output (3.86e33 ergs/second or 386 billion billion megawatts) is produced by nuclear fusion reactions. Each second about 700,000,000 tons of hydrogen are converted to about 695,000,000 tons of helium and 5,000,000 tons (=3.86e33 ergs) of energy in the form of gamma rays. As it travels out toward the surface, the energy is continuously absorbed and re-emitted at lower and lower temperatures so that by the time it reaches the surface, it is primarily visible light. For the last 20% of the way to the surface the energy is carried more by convection than by radiation.

If you are approaching this problem from an environmental point of view, then you will use toe's

The flow of renewable solar energies on earth is essentially equal to the flow of energy due to solar radiation. Every year, the sun irradiates the earth's land masses with the equivalent of 19 trillion toe. A fraction of this energy could satisfy the world's energy requirements, around 9 billion toe per year.

The ton of oil equivalent (toe) is a unit of energy: the amount of energy released by burning one metric ton of crude oil, approximately 10 Gcalth or 42 GJ (as different crude oils have different calorific values, the exact value of the toe is defined by convention; unfortunately there are several slightly different definitions as discussed below).

The toe is commonly used for large amounts of energy, as it is more intuitive to visualise, say, the energy released by burning 1000 number of tonnes of oil than 42,000 billion joules (the SI unit of energy).

A barrel of oil equivalent (boe), also a unit of energy, contains approximately 0.146 toe (i.e. there are approximately 6.841 boe in a toe).

Multiples of the toe are used, in particular the megatoe (Mtoe, one million toe) and the gigatoe (Gtoe, one billion toe).

The IEA/OECD define one toe to be 10 Gcalth, equal to 41.868 GJ [1] or 11.625 MWh.

Some organisations use other conversion factors, for example:

One toe = 42 GJ
one toe = 41.85 GJ[2]
One toe = 7.11, 7.33, or 7.4 boe
One ton petroleum equivalent (TPE), a parameter used in renewable energy, 10,800,000,000 calIT (45.217 gigajoules).

Gathering reliable solar data is important to planners and developers who are looking to site systems for solar energy generation. Common systems include a Sunshine Duration Meter - which provides accurate measurement of sunshine duration as defined by the WMO (the time during which the direct solar radiation exceeds the level of 120 W/m2).

A variety of pyranometers can be used to measure the solar energy available. A wide range of pyranometers is available, each better suited to a particular task or to a type of location. Combining sunshine duration data with solar radiation measurements is vital to determining suitable locations of large photovoltaic generating stations.

On-going monitoring of the effectiveness of photovoltaic systems can be achieved by use of a Net Radiometer - which provides the measurement of the balance between incoming and outgoing radiation, along with albedo analysis and sky and ground temperature measurements.
