28. Solar Power station to provide all of Australia’s energy needs ? Legend greater than 24MJ/m2day less than 24 but greater than 23mJ/m2day less than 23 but greater than 22mJ/m2day less than 22 but greater than 20mJ/m2day less than 20 but greater than 18mJ/m2day less than 18 but greater than 16mJ/m2day less than 16MJ/m2day Australian and New Zealand Solar Energy Society

29. Land Area for a Solar Future Assume: 5000Wh/m 2 /day average insolation 5000PJ = 5x10 18 J required per year Conversion of solar energy at 20% efficiency 5000Wh/m 2 /day x 365days x 0.2 = 1314MJ/m 2 /year (5 x 10 18 J/year)/(1.314 x 10 9 J/m 2 /year) = 3.81 x 10 9 m 2 =3805km 2 = 61.7km x 61.7km Allowing for spacing between collectors: @ 10% coverage; 38052km 2 = 195km x 195km @ 20% coverage; 19026km 2 = 138km x 138km
