Dear Nando, > It seems that I living in a different planet, because in my Terra the > Sun produces 1 KW/M2, where are you located to produce 3 or 5 KWH/M2?
No, we actually live on the same planet... The problem is just that you didn't read the post carefully enough! I will repost the relevant sentence from my post: >> At my latitude (30 degrees) I would count on 5kWh >> per day per square meter in summer. Did you read it with enough detention this time? It's an ENERGY of 5 kilowatt HOURS, PER DAY, per square meter. Of course, the highest power density you can except of the sun is roughly 1kW per square meter, but considering that you have sun for 10 to 14 hours a day, and that during most of these hours the power density is less than 1kW/m2, getting down to zero at the start and the end of each day, it seems very reasonable that the total energy collected during one full day from each square meter is in the neighborhood of 5kWh for my location (30 degrees), and closer to 3kWh at a certain latitude farther away from the equator, as assumed by the author of the original post, who also clearly stated energy per day and not power: >>>> I would expect that the sun radiates energy at about 3kWhr per >>>> square meter per day at temperate areas Clear? Well, you don't need to blush. When I first read the original post, I also jumped: "That's wrong! It's only 1kW per square meter!" But then I read again, and noticed he was writing about energy per day, and not power. Case solved...
