Install Costs

I got a few bids on a system install. The first I felt was a pretty decent bid but then coming and exploring here, it was about $3.25 per watt installed and most folks here suggest that anything over $3 per watt is paying too much. So I got another quote that was significantly higher, ($4.50 per watt) and if I wanted a non-Tesla battery option that would go up due to needing to install the enphase inverters under the panels.

I have limited roof space so would only be able to install about 13 panels, which amounts to 50% of my current use. I imagine if I could install closer to 100% offset the cost would come down significantly since a lot of the install costs are fixed.

I'm in the Pacific NW, and the two other mitigating factors here would be that my home is three stories and the roof pitch is right around 40 degrees.

With all the above in mind is $3.25 per watt too much to pay? Is the second quote (from a highly regarded and recommended installer) completely out of line? I appreciate any thoughts. Electricity is still cheap here but it has been going up exponentially lately. I'm also nervous about the new admin changing the tax credits before I can take them, since I would sign in 2024 but install would be early next year.

All of the installs used Silfab 430 QD panels.

Also my three battery options were between Tesla PowerWall, Enphase and PointGuard. I think the PointGuard is most impressive - cost is comparable to Tesla but a smaller footprint and appears to be easily expandable - if anyone has thoughts on that.

Appreciate all thoughts.
