solar panel array
Are there better angles to the alignment point of the photovoltaic solar panels as seasonal use?
I'm planning a small selection photovoltaic panels to supplement the lighting needs in a summer camp. It will only be occupied from May to September, and wondered if the angle the southern tip and tilt angles should be modified for seasonal use. N43 1.661 Lat Lon W71 48,957 gladly exchange for increased production the summer season for the cookbook, "" answers to "the year" performance. I have zero degree, south the case for the northern hemisphere, point angle and latitude plus 15 degrees of tilt, "cookbook answers," I'm looking for something better.
If Google software solar modeling "or similar terms, there are several programs people have developed for modeling the sun that falls on a site, given a particular latitude and longitude. One example is the http://www.f1.fhtw-berlin.de/studiengang/ut/desire/en/index.htm but I disagree with that program in any way. There is also evidence of heatstroke for the U.S. gathered by the National renewable energy laboratory in http://rredc.nrel.gov/solar/old_data/nsrdb/redbook/atlas/ The above is very good, as the actual data collected in recent decades and as such, takes into account the effects of clouds, temperatures prevailing winds, etc. You could go month to month with the data and the model of a particular slope. In general, if you want to optimize the harshness of summer, go to minus 15 degrees latitude in the northern hemisphere. You will also want ensure that the panels are mounted with good air circulation around them (ie, not flush against the roof surface hot) as you can lose 10, even 20% production when the panels get really hot. Meters Consider also whether you may be able to tie network and its solar net (check with the company electric) – in which case, you must build a financial credit for the winter. If the array is in the thousands of watts, which would make sense. If you are thinking in small point light sources, with (say) NiCd rechargeable batteries, then I would say that sounds fun, but it would be good questions about the cost or performance lights. I hope it works, the same!
