Re: [RE-wrenches] overfeed 7kW gridtie inverter or drop a mod per string?
Hi Jim, I like using one of the design emulators for just this reason. PVSYST and PVSOL. You can model each scenario and see how the numbers crunch. You import historical weather data for the region to get as accurate as possible. You mention the silver painted roof, these emulators allow you to input albedo affects, too. Both packages offer free trial periods, so you could run just this case for free. If you like them then you spend the money for the license. -Wes Kennedy NABCEP certified PV Installer 303-653-3073 --- On Mon, 4/19/10, Jim MacDonald j...@solaresystems.com wrote: From: Jim MacDonald j...@solaresystems.com Subject: Re: [RE-wrenches] overfeed 7kW gridtie inverter or drop a mod per string?

Re: [RE-wrenches] Service Magic update request
Allan: Things may have changed since we used them (or rather, vice versa). This outfit is certainly ramping up their advertising media dollars. My advice would be 1) Make sure you do not mind having to cancel the credit card you give them (you may want to terminate service later); 2) Get and READ their lead return policy become a speed demon when returning leads. Along with the occasional solar lead, you may be receiving names of people who want to do anything for their home from re-roofing to installing double pane windows on the doghouse. And get used to seeing the same contractors bidding against you on any of their referrals. SunPower has recently engaged their services on a trial basis but we are loathe to give them a credit card number. The only magic for us was how they made our dollars disappearbut things may be different now. Calfinder is cut from the same cloth - quite literally.

Re: [RE-wrenches] Modules with PV wire
This is another example of the manufacturers doing whatever and let the installers just deal with it. We just finished a campus wide lighting of all remote signage with custom solar lighting systems. We made up pre-packaged mini-pole mounts with the modules attached so when we got out on site there was only final wiring hookup required. However, several of our systems required different module sizes due to differences in wattage and number of lights. The campus was a 2 hour drive each way from shop, and when we started to assemble everything we found half of the modules had solar wire pigtails and half had USE-2 pigtails. The pre-assembled M/F wiring extensions we ordered to save having to make our own were also a mix of wire types, and at least half of these wires would not fit through the 2-hole cable connectors we normally install on the combiner boxes as they all had a different outside diameter. Some of the other cables fit very loosely in the 2-hole connectors which will not be a very good moisture barrier.We tried cable glide goop on the largest cables and they still would not fit through these connectors. This little mix-up lost us another day in field work and a very long return trip that should not have been require. As westart receivingall this non-standardized stuff, better check everything twice.
