00:00 Paul Braren gives a tour of the exterior of Little House Brewing, Dec. 4, 2021
01:38 CT Green Building Council Dec 18th open house event announcement
01:45 Co-owner Sam Wagner introduces the other co-owner Carlisle Schaeffer, Sam begins answering questions
02:25 Sam has a Tesla Model 3, solar roofer is a local friend, building was built in 1836
03:14 Feb 2021 placed order, followed by price changes, Tesla used to a lot of new construction in southwest
03:55 took 2 days, subcontractors tear off the old roof, up to 14 workers at a time
04:25 design experience was a little tough, it's a residential product
04:52 permitting by town of Chester was a breeze, final inspection expected at the end of December
05:36 load bearing issues? no, dummy tile to show us is not active PV but gives sense of weight
06:26 what % of roof is active PV? estimated 85-90%, system is not grounded, they use 58 to 60 kW per yr.
07:48 open questions about gutters? old ones torn off, Sam wishes Tesla would sell gutters, since Tesla can't use straps under or over the Tesla Solar Roof.
09:22 how has the power been, has it met expectations? Yes, but hard to gauge, new to solar, cloudy weather. It's a 9.2kW system, avg. home in US is 6kW.
11:45 new underlayment & patch work, they did everything
11:55 only 6 to 7% offset since we started, but brewing system & glycol chiller are electric, normal home it'd be like 80-90%.
12:48 Tesla Powerwall battery. If we lose power we could turn off brewing & chillers and be offline 24 hrs.
13:24 26% Federal Tax Credit for any solar project, this one included, & happens to include a tempered glass roof!
15:08 brewing equipment takes a lot of electricity, 3 6,000kW heating elements
17:10 this is a really strong roof with 25 yr. warranty, bullet point #1, we needed a new roof anyway
17:50 What made you go with Tesla Solar Roof instead of Sun Power panels? Sam: I'm a bit of a Tesla fanboy, have a Model 3, like their products, worth it in the end, traditional solar would have required a whole new roof anyway
18:38 How much? Just over $40,000, with so many prices changes since Feb, but almost half that cost is 2 Powerwalls (stacked)
19:57 should shed snow nicely, snow guard topic came up
20:32 did they get in before Tesla price changes? We did they did end up honoring it, despite surprise of $30,000 price increase
21:00 go online and entering your info into the configurator to see current pricing
21:30 Eversource (utility) will pay you to pull from your batteries through its program called Connected Solutions, up to $1700/yr.
24:03 Sam - ideal scenario is all of Chester is dark, Little House is lit up, people are drinking beer, which will pay for that roof real fast
24:23 attendee mentioned Eversource has smart thermostat program, they can take demand off the grid, and get Amazon gift card.(https://enrollmythermostat.com/everso...)
25:17 if you did a new roof plus solar panels, do you think you're better? Yes, the comparison is to a premium roof. It would be far cheaper if we did an asphalt roof. There's a 25 yr. warranty for all the tiles, if anything happens, they just pop the old one out, and put a new one in.
26:27 what happens if there's a leak?
27:40 Sam - we were Tesla is monitoring the tiles, and they would know before we did. (sounds great in theory) What is the protocol? Sam - was told Tesla has a pretty big office in Connecticut, would reach out to them if any tile was shattered by a limb, that's part of 25 yr. warranty, would replace it. What if it's the underlayment with structure damaged, how would that work, insurance etc.
29:23 (Andrew Baumer, in charge of Green Homes Committee) it's a newer, refined product since announcement, an ongoing evolution just like their cars.
Wind rating of class F, fire rating of class A, hail rating of class 3, can only use on roof pitch of 2:12 to 24:12. Sam - dormer is min. pitch, inverter range 3.8 to 7.6 kW and it's 97.5% efficiency.
30:22 he's an early adopter, this is right on the fence of leading and bleeding.
30:47 ANSI FM 4473 for hail, class 3.
30:56 dummy tile close-up
31:00 Exec Director of Connecticut Green Building Council introduced Andrew Baumer- in charge of the Green Homes Committee, he set this up
31:18 off grid demo, lights didn't flicker
31:33 "with that glycol chiller and some of the other equipment and the power spikes, there's no home battery better than the Powerwall by a mile"
31:42 Tesla app demo
32:49 close look at the 2 Powerwalls, 2 meters, Tesla inverter, Tesla gateway, and a 400 amp service panel.
