Re: [RE-wrenches] Metal shingles
We've done a couple of installs on metal shingle roofs and we used the Unirac stand offs with the Oatey boots. We had the standoffs and flashing installed by the roofer so it wouldn't void the roof warranty. It cost about $1500 extra but we thought it was worth if in case of a leak.

Re: [RE-wrenches] Metal shingles
Be sure to check with the roofs installer first. I have had to pay roofers to send a crew out to 'drill holes' to avoid the homeowner losing their warranty on the shingles. Especially if it's a specialty type of roof you don't want to be blamed for leaks or warranty cancellation. Been there done that..

Re: [RE-wrenches] Metal shingles
Jesse, For a particular shingle, it should be held down at the shingles upper and lower overlap. remove all the screws from that particular shingle, a bit wider and then possibly the row above it as well to allow for some flexibility. The shingle should just wiggle in and out of place. If this roof is moulded to appear like a tile (like this… DECRA Tile http://www.decra.com/index.php/products/tile ) or can easily be damaged by stepping on the wrong spot, here are a couple tips… -leave your work boots in the truck and wear some sturdy sneakers/running shoes. Something that doesn't have as wide a sole as typical work boots. -this might help too, I just noticed this.… Walking Instructions http://www.decra.com/index.php/products/walking-instructions . -it doesn't suggest this in the 'walking instructions' but a roofer who only works with this type shared this tip with me and works great! lay strips (10, 12 or 16 for example) of plywood or board across the shingles and only walk on the strips. You can place them along the rows (horizontal), or across several rows (vertical). They distribute your weight and do not slide if the shingle coating is an aggregate.

Re: [RE-wrenches] Metal shingles
Just got back from our project. Yes the the shingles interlock, so its hard to slide the flashing up under. I used 1/16 cut off wheel in the grinder, to cut the lines for the Soladeck. It came out pretty good, but we had a bit of trouble with the interlock grove underneath causing the flashing to ride up a little high.

Re: [RE-wrenches] P1 micro performance
Thanks for sharing the screen capture, Marco. Interesting issues to think about here. This is actually prime clipping season in many places (not sure about Hawaii) due to the cool weather. While there are more sun-hours in the summer, the cell temperatures are often high enough that you won't tend to see rated power out of the modules. While I'm not running performance models for work, the people who do are routinely increasing dc-to-ac ratios, often as high as 1.4-to-1. Having said that, most inverters aren't installed on a roof. (Not yet anyway.) I'd probably lean to a more conservative sizing ratio for micros. While I can imagine some scenarios where I'd be comfortable with a 215 W micro on a 265 W module—like a flat roof install in Vermont, which reportedly doesn't see 1,000 W/m^2 very often—I wouldn't try that here in Texas. On Mar 21, 2013, at 7:54 PM, Marco Mangelsdorf wrote: Check out the output of the modules below at 1PM on this Spring equinox for this system here in Hilo, Hawaii. These mods are SunPower 245s with the Power-One micro 250s. Notice that the AC outputs below are 223 watts and higher. If we had installed Enphase M215s instead, the max output possible would be ~ 224 watts. If there’s clipping this early in the year, imagine the degree to which the clipping will be increasing in the months to come as the solar insolation increases. And these mods were “only” 245s. Enphase states that their M215s are fine with modules up to 265 watts! Imagine the amount of clipping taking place when that kind of pairing takes place. marco image005.png image006.png ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
Re: [RE-wrenches] P1 micro performance
Wrenches, I'm probably a lone voice on this .. and not intending to get overly picky. Could we call power limiting what it is .. limiting, and not clipping? Clipping implies distortion, which isn't the case here. Limiting is just that. The inverter output is limited to some maximum value -- not clipped. The output power curve flattens when integrated over time, but this still isn't distortion in the waveform. It's simply a point in the output where the derivative is zero. Not increasing, not decreasing. Just .. zero. No additional increase in the output for an increase in available energy at the input. Think governor on an engine Thanks.
