good info for solar

[highdesertranger]

while researching solar water well pumping for our cattle ranch i ran across this <a href="http://www.or.nrcs.usda.gov/technic...ntal_engineering/data/SolarTechNote100929.pdf" rel="nofollow" target="_blank">http://www.or.nrcs.usda.gov/technic...ntal_engineering/data/SolarTechNote100929.pdf</a>&nbsp;.i know it's kinda of long and a little technical in some parts but there is some good info.&nbsp; i liked the parts were they talked about tilt and give easy formulas to get it right.&nbsp; they also give a link to a map that shows what the solar potential is for the whole country.&nbsp; is for a residential size array(4kw) but you can get an idea of your areas potential or you can do the math and make it for small systems.&nbsp; you also have my permission to ignore the parts about the water pumping.&nbsp; highdesertranger

Thanks for that link. It has some good info. especially liked the +-15 degrees for angle change from summer to winter months.<br><br>Here is a great calculator that shows best pv angle depending on the time of year and where you are located. you input your country. for USA you input state and select a city. pretty easy.<br><a href="http://solarelectricityhandbook.com/solar-angle-calculator.html" rel="nofollow" target="_blank"><br>http://solarelectricityhandbook.com/solar-angle-calculator.html</a>

<EM><STRONG><SPAN style="COLOR: #888888">A nice add on to one of these systems (if it mounted off the building) is a solar tracker. It automactically tracks the angle of the sun at any time of year.</SPAN></STRONG></EM><BR><EM><STRONG><SPAN style="COLOR: #888888">Heres a 5kw one. Theres some good stuff out there.
