I just received my system design and I'm a little surprised but I'm no expert. Can I get a look over by the group here?
It looks like they are doing 30 panels, 30 microinverters and 2 Powerwalls to create a 12kW system size, estimating 16,536kWh annual consumption. I don't know why they are setting a goal of 24,500kWH seeing that my consumption from September 1, 2021 to July 31, 2022 was 7,312kWh. I've oversized my system knowing I'm going to use more energy and add a EV in the future, but don't know where 24,500kWh is coming from.
Few questions I had on initial design
1. I was surprised that they are having all the equipment outside. I was thinking they were going to have it inside the garage along the same wall they are diagrammed. They told me they couldn't do that?
2. In the bottom left corner, you can see they have one of my batteries not behind the fence (left side of fence is open to front of house, right side of fence is backyard). Can't they stack both batteries to keep the hardware behind the fence and not accessible from someone just walking along the street?
3. I have my main panel and then a sub panel inside the garage. It looks like they are installing another sub panel outside (100A ESS Sub Panel). Is that typical? They said they are doing this because the batteries will be tied to that and back up everything in there?
4. You will see in the Critical Loads Panel Schedule, they are saying customer needs to install soft started on all AC units and needs to turn off all loads above 40A during outage. Doesn't this defeat the purpose of having the battery running AC during outage or do most people don't back up their AC?
The contract system was shy of $60K before tax credit. They are charging now an additional $2000 for whole home transfer and $1500 for equipment location.
Maybe I'm dumb, but does anything stand out as "strange" here?
