"The maximum available energy is 1W/meter^2 at ground"
Where are you from, Britain?
http://en.wikipedia.org/wiki/Sunlight http://en.wikipedia.org/wiki/Sunlight
""sunshine duration" to mean the cumulative time during which an area receives direct irradiance from the Sun of at least 120 watts per meter"
"The total amount of energy received at ground level from the sun at the zenith is 1004 watts per square meter"
This depends on altitude of course, the maximum is over 1300W in space.
- yungchin 13y agoHah, not even in Britain does it get that bad :) http://www.withouthotair.com/c6/page_38.shtml http://www.withouthotair.com/c6/page_38.shtml - see fig 6.2
- Roboprog 13y agoI assumed he meant "1 kW" and missed the k.
- dredmorbius 13y agoQuite.
- dredmorbius 13y agoWhere are you from, Britain? Doh! 1kW/meter^2. Apologies. More closer to the equator, less in higher lattitudes and/or where topography (valleys, canyons) or weather (fog, clouds) interfere, though even diffuse sunlight can provide significant power.
