[RE-wrenches] Presentation to Fire Fighters
Wrenches, I know some of you have done presentations to fire fighters in the past. I have one of these presentations coming up in about a month and wanted to see if anyone was willing to share their slide shows. If you are please contact me off list.

[RE-wrenches] Flashing vs Sealant... again (is sealant code defensible?)
1. I'm interest in a poll of installers who are using flashings vs sealant. Now that the flashing market has evolved, what are you using today? When did you switch to flashings (if you did). And why not, if you still prefer sealant. 2. Is there a any code defense for sealant systems ? (L-foot sealed down to shingles). Does anyone know of a scientific shootout between sealants and flashings? Here is my view: The construction industry is slow to evolve. Sealants, clauks adhesives are not trusted in general, due to the legacy of code, and we have a mechanical vs. chemical industry bias. There is something about seeing a flashing that says, that is a professional job, it must comply with code. And yet, my experience says I'd trust a 50-year silicone over a flashing that depends on gravity. Gravity should be dependable right? But anyone in snow country can tell you in spring, water can go uphill after ice dams form. There are high-rise buildings that use structural glazing which is just glass and silicone. These systems are now getting to be 50 years old without issue. The cost of flashings have come down in the last few years, but so has the cost per watt of installs. With 50 feet in a typical install around here that is $150 in feet, lags silicone. Or $1500 in flashings, and extra labor. That can be a large part of a bid, and make you more expensive in a competitive landscape. That is fine, if it adds value... but I personally don't see the proven value, other than the appearance of code defensibility.

Re: [RE-wrenches] Flashing vs Sealant... again (is sealant code defensible?)
Hi Troy, There has been an ongoing debate on the RE-Wrenches list on this issue for years now. I've personally serviced many old L-feet systems that are fine and some that are leaking. The leaks normally occur in the missed holes adjacent to the L-foot. Also, many installers were using Sikaflex which over time loses its adhesion to comp shingles. Sloppy work is the worst culprit. We've used all sorts of flashings over the years and primarily stick with Quickmount E-series these days. All holes, both hits and misses, are squirted with M-1 sealant (from Chemlink) and we slide aluminum flashing (standard rolls of aluminum cut to size in the field) under the shingles for the missed holes. We've never had a leak with a properly flashed system and I am a strong proponent for using flashing products for all mounting points.

Re: [RE-wrenches] Presentation to Fire Fighters
Hello Will; I've contacted you off list, but am posting here so the information is out there. I do teach a ISPQ / IREC / NABCEP accredited class for RE professionals on what and how to teach firefighters, and because travel is such an expensive PITA am working towards an online version this year; the first online class is coming up later this month. In my opinion, the issues are overblown a bit on both sides by both RE installers and firefighters, the Code / AHJ reactions are in the right spirit but not satisfoactory yet, and OUTREACH training from RE professionals to firefighters is by far the most important factor.

Re: [RE-wrenches] Flashing vs Sealant... again (is sealant code defensible?)
It definitely depends on the flashing. The Oatey type with the rubber gasket die after several years, and leak. For our installations, it really depends on the roof. In some cases with metal roofs, a flashing can't really have the overlap needed, and so it just becomes a big gooed on L foot really. Also, I look at L feet as a small 2 x 2 flashing. Relative to the hole size this is often a reasonable amount of sealing surface. Compare this to your average 4 plumbing penetration vs the size of the flashing. Look at how bulk head fittings on water tanks work. They're under several feet of water, and depend on a rubber gasket, not a flashing. I also consider what's under the roof too. A leak on an open carport is not as much liability as a leak over the vintage Steinway grand piano. Finally, if the roof is already having problems, (I love when they say: it only leaks when it rains..) you need to look at re roofing, and have the roofer seal around your mounts.

Re: [RE-wrenches] Flashing vs Sealant... again (is sealant code defensible?)
I would have to definitely lean towards using flashings as a default and have been doing so now for several years. Last project i wanted to use flashings on and couldn't was in 2010. I couldn't because it was a 10-13 deg slope with asphalt shingles that were really good quality and made for low slope and resistant to high wind, this meant that each course of shingle was very well adhered to the course below it, to the point that it was next to impossible to lift the shingles to insert a flashing. I tried everything short of using a heat gun or torch to warm them up first. I cannot quote anything, but i believe that there is an issue with voiding roof warranties if you do not flash a penetration. Always make sure that the sealant you choose is compatible with the roof and any other material it will contact. I believe there was an issue years ago where many installers were using a popular sealant that (if you read the small print) was not compatible with asphalt shingles. My sealant of choice these days is Henry 925. I would be very interested to see, if anyone would be willing to share (on or off-list), photos of any signs of leaking or leak damage caused by failed roof penetrations.

Re: [RE-wrenches] Flashing vs Sealant... again (is sealant code defensible?)
Hi Ray, Ten plus years ago, I observed this one thermal installation which also used the Oatey flexible gasket. Most all the 80's era installs had seriously deteriorated gaskets _except_ this one where the homeowner had painted everything with latex paint. That gasket was not deteriorated and was still flexible. That small UV film barrier was really beneficial. Automotive CV boots are available with a split for replacement use. I'm told that if you allow the glue to dry properly (without moving the steering wheel) it works as good as the non split model. I would not be surprised if a similar product exists for plumbing/electrical penetrations. With paint, that should be the last gasket replacement.

[RE-wrenches] Golf Cart Array
Esteemed and just steamed Fellows, I've rebuilt an old dead 36V golf cart and I'd like to put an array on it. The problem is that the roof area is only 40 x 65ish and it's 36V. I'm OK with a bit of overhang the 65 dimension, but not side to side as it will be a head bumper getting in and out. Don't want to put anything less than 150W up there and more, of course, is mo betta. Got an MPPT controller embedded in so higher voltage is not an issue. My first thought is to find three old M55s which are only 13 wide, but I'm open to whatever. The beauty of the M55s would be they are UPS-able. So... anybody got some? Other suggestions? Got lots of trading stock.

Re: [RE-wrenches] Golf Cart Array
Bob-O I did that once for a client, I used 3 Yingli 75s , they fit well but the array turned out to be to heavy for the Golf Carts roof frame, stress cracks started showing up. I think I still have the 36 volt charge controller, built by Solar Converters, it never got installed, if you happen to need one its available.

Re: [RE-wrenches] wrenches] Golf Cart Array
Bob-O I have a golf cart going on 5 years with 3 Sunwize 80 watt panels. The only time we have plugged it in to a charger was a few days when the cart was working all day long each day for 3 days in a row at SolarFest picking up the trash and recycling. We use it on our sheep farm the rest of the year and never plug it in. We go up and down a 1 mile driveway with 500' vertical. Just did our first run this morning after having it sit in a snow drift all winter. We just quit using our snowmobile to traverse the driveway and now we are in mud season. Cart made it down and partway back up before getting stuck in the mud. We have a Midnite Solar BCM to keep tabs on the battery and it has weathered 3 years outside mounted on the dash. I still need a charge controller... now I just keep turning the array on and off with a DC breaker in the battery compartment. With something like the KID, most any panels would work. We have kind of cooked the batteries from time to time... definitely got equalized. The MNBCM is reading low voltage right now as it thinks we are a 48v system.! You can see a picture of it on my personal Facebook timeline.
