Recent customer feedback about pv solar system design & installation services.
From the first walkthrough to final utility sign-off, here's how a solar project moves forward with J. Thomas & Son Services.
We evaluate your roof condition, sun exposure, shading, and household electrical load to determine system size and panel placement.
You'll get a proposed layout covering panel type, inverter choice, and whether battery storage makes sense for your home.
We handle permitting with local jurisdictions and coordinate interconnection paperwork with NorthWestern Energy so the process moves without delays on your end.
Our crew installs panels, mounts, wiring, subpanels, and grounding, keeping the work area clean and the disruption to your roof and yard minimal.
After final inspection and utility approval, we activate the system and set up monitoring so you can track energy production and savings.
Get clear answers about pv solar system design & installation, preparation, timing, maintenance, and what to expect before requesting an estimate.
Q1
Cost depends on system size, roof type, panel quality, and whether battery storage is added. Ground-mounted arrays and hybrid inverter setups typically run higher than a standard roof-mounted grid-tied system. We provide a specific estimate after your site assessment.
Q2
When your panels produce more power than your home uses, the excess feeds back into the grid through NorthWestern Energy's net metering program, earning you credit toward future electric bills during lower-production months.
Q3
Most residential installs take one to a few days once permitting and equipment are in place. The full timeline, including design, permitting, and utility interconnection, generally spans several weeks depending on system size and local approvals.
Q4
Yes. Homeowners can apply for the federal Investment Tax Credit on system costs, and Montana offers a property tax exemption for qualifying solar installations. We can walk you through how these apply to your specific project.
Q5
Yes. We design systems with battery integration for backup power during outages or for time-of-use savings, and we can add storage to existing grid-tied systems in many cases.
Q6
Yes, ground-mounted arrays are a good option for properties with limited roof space or shading issues, common on larger lots around Bigfork and Columbia Falls. We handle design and installation for both roof and ground-mounted setups.
Q7
It depends on your panel's age and capacity. During the site assessment, we check whether your existing panel can support a solar connection or if a service upgrade is needed first.
