Re: [RE-wrenches] Racking on residential rooftops

We also never had luck with a laser, although early on that is something we definitely tried. We use a string line. We keep drops of 2x4 that are cut to the length of our most common panel sizes, and fasten them on to the rails with mid clips. That way we can easily reference where the top and bott

Re: [RE-wrenches] DC fan for greenhouse

We had used some Snap-Fans many many years ago on some greenhouse applications. Looks like they are still in business and their product line has expanded so that says something…. http://www.snap-fan.com/ Adam Katzman (he/him) Autonomous Energies | Owner/Operator www.AutonomousEnergies.com

[RE-wrenches] IRA Domestic Content Bonus Credit

Wrenches, I'm wondering if any of you have thoughts/experience with the additional 10% ITC that the Inflation Reduction Act allocates for "domestic content". I'm doing some googling but not really sure what equipment (racking, panels, inverters, BOM, etc) we would need to install in order to qualif

Are helical piles overkill for what you are trying to do? They can be unscrewed when you are done so nothing is left behind. Adam Katzman (he/him) Autonomous Energies | Owner/Operator www.AutonomousEnergies.com (518) 567-1468 On Tue, Apr 9, 2024 at 4:17 PM Ni

Re: [RE-wrenches] USDA Rural Development fund

We were able to access that a few years ago for a brewery project and were granted the money. I used a grant writer who works with solar companies specifically on accessing that funding. Their intake online walked you through what you may or may not be eligible for. They were great to work with an

Re: [RE-wrenches] SMA String inverters

We haven’t used the -41s for just over a year, because they aren’t UL1741SB compliant (which became required here in NY last January). Additionally, the last time we did use the -41s we discovered (upon receiving the units) that they weren’t WiFi compatible anymore (due to some parts shortages) and

[RE-wrenches] Enphase Gateway causing lamp to flicker

Wrenches We have a project where the homeowner has some of those bedside lamps where you touch them to turn them on/off/dim (rather than having a switch). It seems like when the Enphase Gateway is powered up it causes the lights to freak out. Once we flip the breaker to the Gateway off the lamp ope

[RE-wrenches] APSystems Micros

Wrenches Anyone have experience/thoughts on the APSystems 2:1 single phase micros. I don’t see much in the archives and the internet has some mixed reviews. I’m mostly on the Enphase band wagon, but interested in knowing if APS could be considered as a more cost efficient option for larger single p

Re: [RE-wrenches] Fronius USA available 2023 & 2024 ?

I was trying to expand on an older fronius install and asked my greentech rep about when they might have their UL1741SB line out and he said he “hadn’t heard from fronius in a while and wouldn’t be surprised if fronius wasn’t a company in a year or two”. So more or less the same info you heard Mick

[RE-wrenches] SMA Tech Support

Hey all, After the typical 1 hour wait to get up to Level 2 for SMA tech support, the tech mentioned there might be some option where you get registered (or possibly pay) to bypass Level 1? Or somehow get more streamlined service? He didn't know how or where to access that service. Has anyone heard

[RE-wrenches] Bonding Metal Roofs Part II

Hey all, I had started a thread about bonding to metal roofs in 2018 but can't figure out how to respond via the archive. I know some things have changed since then, so I'm circling back and starting a new thread. In NY one of our inspection agencies (NYSERDA) requires bonding of metal roof panels

Re: [RE-wrenches] Solar Roof Jack

We just used a few of these recently. Seemed easy enough and plan on using more on an upcoming project. We had easy access to the vent in the attic which probably helped. Only complaint was that I was worried about the vent cap (provided) blowing off and eventually having debris get in there and ge
