How Much Power Emitted by "the SUN" ?

KISSAN EDUCATION

(www.kissanedu.com)

In early class,we students used to study "SUN is Major sources of Energy" . Here i try to clear every one what is actual meaning of this sentence.

Power emits from sun = 3.8 * 1030 W

Power Density = 6.25 * 1011 W/m2

Solar Perihelion = 1414 W/m2 3 Jan(longest distance from sun)

Aphelion = 1322 W/m2 3 July(Shortest distance from Sun)

Calculation to find out Solar Power density at outer atmosphere over year

St = S[1 + 0.033Sin(360n/365)]

Jan 1, n = 1

Jan 2, n = 2

Jan 31, n = 31

Dec 31, n = 365

Suppose,If you want to find out Solar radiation in upper atmosphere in 31 march.

Thus you can calculate value of Solar Constant For any particular day.

In next Blog, how i would Discuss CAN WE USE SOLAR PV FOR REQUIREMENT OF WORLD POWER ,

Design Solar Plant For House and offices by itself (Understanding Purpose, not Practical)

KISSAN SOLAR EDUCATION ( www.kissanedu.com ) CALCULATE RATING of Solar's Equipment : Are Your Looking for SOLAR DESIGN for your Home, Offices by Itself ? Energy Flow Diagram in a Solar System for Home, Offices To know Rating of Each equipment , you should calculate from Reverse Direction of Energy Flow Diagram. Step 1 : Calculate Load Requirement : Number of load you want to run from Solar. Important Calculation 1. Total wattage of Load : (watt * quantity ) = 9*2 + 60*1 +150*1 . . . . . +250*1 = 628 Watt 2. Total Energy Consumed By load : (wattage * number . of hour used) = 9*5*2 + 60*8*1 + .......+ 250*3*1 = 2820 Wh Step 2 : Find out Size of Inverter , Important : Output Energy of Load = 2820 wh We need to find out Rating of...
