Re: [RE-wrenches] S-5 clamps on the standing seam roof

Paul, We have used the S-5! clamps on standing seams in the past. We like putting the modules directly on the seams with the S-5! clamps, no rails. First, speak with the engineer who designed the building and roof to make sure the roof is attached securely to the perlins and building structure.

[RE-wrenches] FW: Advanced Solar Photonics

Wrenches, Anyone heard of this company? It showed up in my junk email folder, but it appears to be legit: A new manufacturer of UL 1703 monocrystalline 210W 60 cell modules, U.S.-made and located in Florida. They're probably really hurting as a startup with lots of capital investment, offering modu

Re: [RE-wrenches] FW: Advanced Solar Photonics

I've heard of them and they are new. I don't think they're making them in Florida yet but they claim to be US-made. I think that on the previous edition of their website they were planning an 800W crystalline module(!), now they seem to have scaled back to "only" a 600W sometime next year. Th

Re: [RE-wrenches] FW: Advanced Solar Photonics

Thank you, Dave. No plans to order any, as we're not quite in the price-focused race-to-the-bottom in New Mexico yet, and prefer to work with established suppliers. But I am curious, and other Wrenches may have reason to investigate them if they're for real. Allan Allan Sindelar al...@positiveener

[RE-wrenches] S-5 clamps on the standing seam roof

Paul I bid a 21' x 16' PV array on a 1.5:12 standing seam roof using the S-5 PV kits. http://www.s-5.com/clamps/index_686.cfm The seams were 1-1/2" high with a half inch folded lip on top. It seemed like a good idea to mount the modules using the 4-point method you suggest. After clamping a sa

Re: [RE-wrenches] FW250

I agree that the FW250 has a few shortcomings however it does work out quite well on the AC side. My own system has a FW500 DC and a FW250 on the AC side outputting to the existing service panel. It is a bit crowded in the FW250 especially with the FW-SP-250 (surge protector) however I can

[RE-wrenches] wind generators

Despite my vow to never install another wind generator, I have been called to action by an old customer who needs my help. We need to replace a ten year old Whisper (Elliot-area) 1500 watt machine 3-blade, 24 vdc battery bank, three phase to the basement rectifier/controller. I am not at all keen o

[RE-wrenches] RF noise

Hi All, Thought I would update you on the inverter issue (Magnum) that was having lots of noise on FM/AM radio. I tried a choke, no difference. Installed a Outback and there is no noise, the radio is perfect. While I sure like the magnum, I'll have to wait until they make them quieter.
