Solar Company in Billings, MT | Wegner Roofing & Solar
If you own a home or business in Billings, Montana, you already know what energy costs feel like when temperatures drop near the Rimrocks in January, or when summer heat pushes your cooling bill higher than it should be. Utility rates aren’t going down, and every dollar you send to NorthWestern Energy each month is money that doesn’t have to leave your pocket.
Wegner Roofing & Solar is the locally rooted solar company Billings, MT homeowners and business owners have come to trust for high-performance solar energy systems. And right now, eligible residential and commercial installations qualify for the federal 30% Solar Investment Tax Credit, a credit that can reduce thousands of dollars from your upfront system cost before your first panel is ever installed. There has never been a more financially practical time to make the switch.
We’re not a national call center dispatching crews from out of state. We have a real address right here in Billings, 2913 Millennium Cir, Billings, MT 59102, and our team is made up of people who live and work in this community. As trusted solar energy contractors in Billings, MT, we design every system around Montana’s climate, your property’s unique characteristics, and your long-term financial goals. When you work with Wegner Roofing & Solar, you’re working with a company that is fully accountable to the same neighborhoods it serves.
Why Billings, MT Is One of the Best Solar Markets in the Northern Rockies
Most people are surprised to learn just how much solar potential Billings carries. With over 300 days of measurable sunshine per year and significant high-altitude solar irradiance, Yellowstone County is genuinely one of the strongest solar markets in the Northern Rockies, and most homeowners here are leaving that resource completely untapped.
Every day the sun rises over the Rims and sets behind the West End hills, your roof is either working for you, or it isn’t.
Property owners across Billings who have made the transition to solar are seeing real, measurable results:
- Significantly reduced monthly utility bills from NorthWestern Energy
- Long-term protection from future rate increases beyond their control
- Increased home and commercial property resale value
- Access to the 30% federal solar tax credit to reduce upfront investment costs
- Greater energy independence through battery storage options
Whether you own a home in the Heights, a small business on the South Side, a property in the Shiloh area, or a building along the Billings Bench, the solar opportunity is the same. What changes is how the system is designed for your specific situation. That’s where Wegner Roofing & Solar, the solar company Billings, MT property owners rely on, makes the difference.
Solar in Montana Is Different, And We've Built Our Process Around That Reality
Installing solar in Billings, MT is not the same as installing solar in Phoenix or Denver. Montana winters bring significant snowfall, hard freeze-thaw cycles, and hail seasons that demand more from your roof and your panels than most national solar companies are equipped to handle.
At Wegner Roofing & Solar, our roofing expertise is built directly into every solar installation. Before a single panel goes up, we conduct a full structural assessment of your roof, evaluating its age, load capacity, orientation, and overall condition. If your roof needs attention before the solar installation begins, we handle both under one coordinated project. That’s a level of protection most solar-only contractors simply cannot offer.
Our Solar Installation Process in Billings
Step 1, Free On-Site Consultation
We come to your property, review your utility bills, evaluate your roof and site conditions, and give you an honest assessment of what solar can realistically do for your specific situation. No pressure. No inflated numbers.
Step 2, Custom System Design
Every system is engineered specifically for your property, accounting for roof pitch, compass orientation, shading analysis, and your household or business energy consumption patterns. No cookie-cutter layouts.
Step 3, Permitting & Utility Coordination
We handle all required building permits through Yellowstone County and coordinate directly with NorthWestern Energy for grid interconnection approval. You don’t have to navigate that process alone.
Step 4, Professional Installation
Our certified crews complete the installation cleanly, efficiently, and with zero compromise to your roof’s integrity or your property’s appearance.
Step 5, Inspection, Activation & Walkthrough
Once your system passes final inspection and utility approval, we activate your system and walk you through how to monitor your energy production in real time.
Step 6, Continued Local Support
We don’t hand you a warranty card and disappear. We’re a local company. If something comes up after installation, you can reach us directly, and we’ll be here.

Residential Solar Installation
Custom solar systems designed for single-family homes and residential properties throughout Billings. Our Billings solar installers work in established neighborhoods like the Heights, Lockwood, the West End, and throughout the Rimrock and Billings Bench areas, anywhere your roof can support a properly engineered system.
Commercial Solar Installation

Roofing & Solar Integration
Our combined roofing and solar expertise means you get one contractor managing both the structural integrity of your roof and the performance of your solar system. This matters, especially in Montana, where hail, ice, and wind put both systems under real stress.
Solar Battery Storage Systems
Paired battery storage allows you to store the energy your panels produce during peak sunlight hours and use it when the grid is unreliable, when rates are highest, or when the power goes out. Battery storage is increasingly relevant for both residential and commercial customers throughout the Billings region.
System Monitoring, Maintenance & Inspections
After your system is live, we help you understand your production data, perform post-installation inspections, and remain available for ongoing support, especially following hail events or severe weather seasons common to the Billings area.
The Financial Case for Solar in Billings, MT
The numbers behind residential and commercial solar in Billings are worth understanding clearly:
Federal Solar Investment Tax Credit (ITC)
Eligible homeowners and business owners can apply the 30% federal solar tax credit against their full installation cost. The ITC is one of the most impactful financial tools currently available and has helped make the best solar panels Montana property owners can install genuinely affordable for thousands of households and businesses.
Net Metering in Montana
Montana’s net metering policy allows eligible solar customers to receive credit from their utility for excess energy their system sends back to the grid, meaning the energy your panels produce beyond your immediate use doesn’t go to waste.
Long-Term Utility Bill Reduction
Once your system is operational, the energy your panels produce is essentially free. Every kilowatt-hour your system generates is a kilowatt-hour you’re not purchasing from the utility, and that math compounds year over year as rates continue to rise.
Increased Property Value
Studies consistently demonstrate that solar installations increase residential property values, in many cases, by more than the net cost of the system after incentives. For homeowners in Billings, that’s not a speculative benefit. It’s a documented financial outcome.
Commercial Depreciation Benefits
Business owners may qualify for accelerated depreciation under MACRS (Modified Accelerated Cost Recovery System), which can significantly reduce the effective net cost of a commercial solar installation. We discuss this during every commercial consultation.
The longer you wait, the more you continue paying rates you don’t have to pay, and the less time your system has to work for you.
Why Billings Property Owners Choose Wegner Roofing & Solar
There’s no shortage of solar companies marketing to Billings homeowners right now. Here’s what makes Wegner Roofing & Solar different, and why it matters to your investment:
Built From the Ground Up, By Someone Who Did the Work Himself
Wegner Roofing & Solar was founded by Brandon Wegner, who started the business doing every single project from start to finish on his own. Not managing from a distance. Not delegating the details. Personally showing up, doing the work, and holding himself to a standard the construction industry wasn’t used to seeing.
That foundation didn’t change as the company grew, it multiplied. Since 2011, Wegner Roofing & Solar has expanded to multiple offices across the Northern Rockies and surrounding region, built on the same vision and commitment to excellence and community that Brandon started with on day one. When you hire Wegner, you’re hiring a company that was built by someone who cared deeply about the craft before it was ever a business.
A Higher Standard, Not Just a Marketing Line
The construction industry has a reputation problem. Inconsistency, corner-cutting, and overpromising have become frustratingly common. Brandon built Wegner Roofing & Solar specifically to operate above that standard, and that commitment is embedded in how every project is planned, staffed, and executed. It’s why Wegner has become the go-to solar energy contractor in Billings, MT for both residential and commercial projects across every community we serve.
Local Ownership & Direct Accountability
We are locally owned and operated with a physical presence in Billings. When you call our number, (406) 850-9842, you reach a real person connected to this community, not a national call center routing you to whoever is available. That accountability is real, and it shows up in how we manage every project.
Dual Expertise in Roofing and Solar
Most solar companies are solar companies. We are both a certified roofing contractor and a solar energy contractor. That combination protects your home at every stage, from pre-installation structural assessment to long-term performance and weatherproofing. It’s a combination that’s genuinely rare and genuinely valuable in a Montana climate.
Regional Experience That Translates to Better Results
With offices across the Northern Rockies and surrounding region and over a decade of growth behind us, our team has developed deep, real-world experience across diverse markets, climate conditions, and regulatory environments. We understand the permitting processes, utility interconnection requirements, and climate-specific demands of Billings, MT, including what it takes to build a solar system that performs reliably through a Montana winter.
Accreditation, Licensing & Industry Standards
Wegner Roofing & Solar holds the certifications and industry accreditations that reflect verified professional standards, not just marketing claims. Your installation is backed by qualified professionals with credentials that are documented and accountable.
A Reputation Built on Real Customer Experiences
Our growth from one person doing every project himself to a multi-office regional contractor wasn’t built through advertising alone. It was built through honest consultations, clean installations, responsive follow-up, and results that matched what we promised before the work ever began. That track record is reflected in the reviews we’ve earned and the referrals we continue to receive from customers across Billings and every community we serve.
Transparent, Pressure-Free Process
We don’t oversell your system to hit a project number. We design what your property actually needs, give you honest savings projections, explain the real costs alongside the real financial benefits, and let you make a confident, informed decision, without the sales pressure that has unfortunately become common in the solar industry.

Frequently Asked Questions About Solar Installation in Billings, MT
1. How much can solar save on my electricity bill in Billings, MT?
Billings homeowners typically reduce their NorthWestern Energy bills by 50 to 90% after installation. Annual savings range from $800 to $1,800 depending on system size and usage. The federal 30% Investment Tax Credit significantly reduces upfront cost. Most residential systems reach full financial payback within 7 to 10 years.
2. How many solar panels does a typical Billings home need?
Most Billings homes require 18 to 28 panels to offset the majority of their annual energy usage. Residential systems typically range from 6 kW to 12 kW. System size depends on monthly consumption, roof orientation, and shading. Wegner Roofing & Solar sizes every system using 12 months of actual utility data.
3. How long do solar panels last in Montana's climate?
Solar panels are rated for 25 to 30 years of productive output. Most manufacturers guarantee at least 80% power production at year 25. Montana’s cold temperatures actually extend panel lifespan compared to hot climates. Inverters, the system’s most common replacement component, typically require replacement between 10 to 15 years.
4. What is the average solar payback period in Billings, MT?
Residential solar payback in Billings typically ranges from 7 to 10 years after the federal 30% tax credit is applied. Commercial properties using MACRS accelerated depreciation may reach payback in 4 to 6 years. After payback, most systems continue producing low-cost electricity for an additional 15 to 20 years.
5. Can I go completely off-grid with solar in Billings, MT?
Going fully off-grid requires an oversized array and 20 to 40 kWh of battery storage to cover Montana’s winter low-production periods. Most homeowners find a grid-tied system with battery backup delivers comparable energy resilience at 30 to 50% lower cost than a true off-grid configuration.
6. How long does a solar installation take from start to finish in Billings?
Physical installation takes 1 to 3 days on-site. The full project timeline, including system design, Yellowstone County permitting, and NorthWestern Energy interconnection approval, typically runs 4 to 8 weeks from signed contract to system activation. Wegner Roofing & Solar manages every step so customers face no permitting delays on their own.
7. What happens to solar panels during a Montana hail storm?
Quality solar panels meet IEC 61215 standards, tested to withstand 1-inch hailstones at 50 mph. Most panels perform well through typical Billings hail events. Severe storms can cause damage. Wegner Roofing & Solar provides post-storm inspections and assists with insurance claim coordination as part of our ongoing customer support.
8. Do solar panels work on an east- or west-facing roof in Billings?
East- and west-facing roofs produce viable solar systems in Billings, typically generating 10 to 20% less than a south-facing array. North-facing roofs are generally not recommended, output drops 30 to 40%. Wegner Roofing & Solar conducts a full orientation and shading analysis before designing any system to maximize annual production potential.
