An incognito window in Chrome worked for me; had no problems in Firefox, which I had never used for PVWatts before; no matter what I did in Safari I could not get it to work. I'm assuming it totally rocks in IE?!? :) Brian Mehalic NABCEP Certified Solar PV Installation Professionalâ„¢ R031508-59

Anyone else notice that the PVWatts website is not working or do i have a personal (computer) problem. I sent feedback to no avail and there is nothing on their twitter account about an issue. When i enter a location, it tells me to enter a different location and says that it's loading the map,

You're not alone. I tried several times today and it's not working for me either. I sent a Tweet on #PVWATTS but no response there either. Gary Willett Icarus Engineering LLC Sent from my iPhone 5s On Jun 3, 2015, at 10:56 PM, Kristopher Schmid sol...@legacysolar.com wrote: Anyone else

[RE-wrenches] PVWatts Module Temperature Coefficient (was Enphase derate)

2010-04-19 Thread Joel Davidson
Wrenches, PVWatts does not accurately predicate Unisolar and Sunpower module performance because it uses a generic single crystal silicon solar module power temperature coefficient (I think -0.4% per degree C). Does someone have the technical paper that specifies PVWatts module temperature
