Re: [RE-wrenches] CEC module rating testing

If the PTC is calculated from the STC and not the results of testing at "PVUSA Test Conditions", then it's of somewhat dubious utility as a predictor of performance, since it's a function of an already questionable quantity - the STC. What the PTC and STC _should_ measure is well-defined: "PTC re

Re: [RE-wrenches] CEC module rating testing

Jerry, The CEC formula for PTC uses the NOCT of the module, the STC rating, the power temperature coefficient and the aperature area of the module. The data is supplied by the manufacturer but must make sense. Starting July 1, 2009, this will have to be certified by an acredited testing lab. L

Re: [RE-wrenches] Retail sales and other issues

I have been compiling sales contract's terms and sent to me from many of you off list to see if I could come up with a standard form of contract terms that I will distribute to anyone why has contacted me off list for a copy.  The idea is to give newer installers some "clauses" they might not think

[RE-wrenches] CEC module rating testing

Wrenches, Can anyone tell how PTC ratings are determined for modules on the CEC list of eligible modules? I seem to recall having heard that the manufacturers provide this data on the honor system. Can anyone verify this? The test is obviously more involved than flash testing at STC. Even th

Does anyone have any RC-6 remote controls? I need 6 of them. I can use RC-7's if no one has the RC-6. Kindest Regards, Larry Crutcher Starlight Solar 11279 S. Glenwood Ave #4 Yuma, AZ 85367 (928) 941-1660 [EMAIL PROTECTED] www.starlightsolar.com Retail Store: 2998 Shari, Yuma, AZ Renewa

Re: [RE-wrenches] DLO wires in PV systems

Mike, If they are not in conduit (a raceway), then they are exposed. They may not be and must not be subject to physical damage (protected by the modules, etc.), but that does not mean they are not exposed and must have the USE-2 / PV rating. Mark Frye Berkeley Solar Electric Systems 303 Red

Re: [RE-wrenches] DLO wires in PV systems

The wires are in a Solardock mounting system, so they are not exposed, and are then run in conduit. Is the UV exposure rating the only difference? Mike _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Frye Sent: Monday, December 01, 2008 3:51 PM To: '

Re: [RE-wrenches] DLO wires in PV systems

Mike, The RHH/RHW-2 do not cross to USE-2 because they do not have any rating for UV exposure. If these conductors are run outside of conduit on the array, you need USE-2 or PV conductor. Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024

We have a 4KW pv system installed and the local inspector wants to use this as a test case so he is crossing all T's and dotting all I's. Which I am happy to help him out with training his other inspectors We are running into an issue on the module output wires. USE-2 or PV rated is how the cod

Our customers already had the Outback gen-verter system in place from few years ago--we could not justify replacing them. i have looked into the Sunny Islands though, and they seem like a good way to go in the future. As an aside, I had originally planned on a Sunnyboy grid tie inverter instea
