Celebrating 24 Years of Full Spectrum Solar

/in , /by

A look back at more than two decades of solar work across Wisconsin—and the communities that have trusted us along the way.

This August marks 24 years of Full Spectrum Solar, a milestone that gives us a good reason to look back at how far we’ve come.Since our beginning in 2002, we have watched solar evolve from a relatively uncommon technology into an important part of how Wisconsin homes, businesses, farms, and organizations think about energy. Through those changes, our focus has remained the same: provide thoughtful system design, quality installation, honest guidance, and long-term support for the people who trust us with their projects.
 
Looking through our installation history helps put those 24 years into perspective. After cleaning and consolidating our project records, we identified more than 1,600 unique installation locations across Wisconsin. The concentration is strongest around Madison and Dane County, but our work stretches well beyond the immediate area into communities throughout southern, central, and southeastern Wisconsin.

Every dot on the map below represents more than a solar array. It represents a homeowner, business, farm, nonprofit, or organization that made an investment in its energy future—and a project our team had the opportunity to help bring to life.

As we celebrate our 24th birthday, we are grateful to the customers, employees, partners, and communities that have supported Full Spectrum Solar along the way. We’re proud of the work behind us and excited to keep building on it as we head toward year 25.

Protect Your Solar Investment with Critter Guard

/in , /by

Solar panels create a sheltered space beneath the array that can be attractive to squirrels, birds, and other small animals. Unfortunately, those unexpected guests can build nests, store debris, or chew on wiring—potentially leading to costly service work and system downtime.

Critter Guard is a durable mesh barrier installed around the perimeter of a solar array. It is designed to block animals from getting underneath the panels while still allowing proper airflow and drainage. Because the mesh is low-profile, it is typically difficult to notice from the ground and does not interfere with normal solar production.

For many homeowners, Critter Guard is inexpensive protection for a much larger investment. Installing it when a solar system is new can be especially convenient, since crews already have safe roof access and can fit the barrier neatly around the array. A little prevention today can help protect wiring, roofing, and long-term system reliability for years to come.

Hail

April 15, 2026: Hail Storm Resources

/in , /by

The hailstorm that moved through southern Wisconsin on April 15, 2026 was not a typical spring event. Large, wind-driven hail caused widespread impact to roofs, siding, and solar systems across the region—often in ways that aren’t immediately visible from the ground.

What makes storms like this particularly challenging is that damage doesn’t always announce itself clearly. A roof can appear intact while underlying materials are compromised. Solar panels may still produce power, even with internal fractures that reduce long-term performance or lead to failure months later.

For many homeowners, the uncertainty is the hardest part:
Is there damage? How serious is it? What does insurance actually cover?

Start With the Right Tools

Rather than guessing—or waiting until a small issue becomes a larger one—the best next step is to begin with a structured assessment.

We’ve built a dedicated resource to help you do exactly that:

👉 https://fullspectrumsolar.com/hail-damage-calculator

This page is designed to give you a clear starting point, not a sales pitch. There, you can:

  • Evaluate potential roof and solar damage
  • Use an interactive calculator to understand rough repair or replacement costs
  • Prepare for conversations with your insurance provider
  • Understand when a repair vs. full replacement makes sense

Why Acting Early Matters

Insurance claims related to storm damage are time-sensitive, and early documentation can make a meaningful difference. Just as important, solar systems introduce an added layer—panels may no longer have exact replacements available, and what appears to be minor damage can evolve into a broader system issue.

Starting the process early doesn’t commit you to anything—it simply puts you in control of the situation.

A Practical Next Step

If your home was in the path of the April 15 storm, it’s worth taking a few minutes to understand where you stand.

Visit the calculator, explore the guidance, and get a sense of what your next move should be:

From there, if you choose to move forward, you’ll be doing so with clarity—and with the right information in hand.

How Battery Backup Protects Your Home During an Outage

/in , /by

When the grid goes down, a home battery backup system keeps your lights on and your life moving. Unlike a portable generator, a battery system responds automatically—often within a fraction of a second—so you may not even notice the outage. The system isolates your home from the grid, powers essential circuits, and delivers clean, quiet electricity without fuel, fumes, or extension cords.

Battery backups are typically paired with solar, allowing your panels to continue producing energy during daylight hours. That means your refrigerator stays cold, your sump pump keeps running, medical devices remain powered, and you can charge phones and laptops to stay connected. Smart energy management lets you prioritize high-need circuits and extend runtime during longer outages.

Beyond resilience, batteries provide peace of mind. Severe weather events are becoming more common, and utility disruptions can last hours—or days. A properly sized battery system turns your home into a self-sustaining hub, protecting comfort, safety, and productivity when you need it most.


The Design Reason Most Home Solar Panels Are Black

/in , /by

Residential solar panels are typically black-framed for both aesthetic and performance reasons. From a design standpoint, black frames pair well with modern roofing materials such as asphalt shingles, standing seam metal, and dark architectural tiles. Homeowners often prefer a low-profile, uniform look that blends seamlessly with the roofline rather than drawing attention. All-black modules — featuring black frames, black back sheets, and dark cells — create a sleek, cohesive appearance that many HOAs and design-conscious neighborhoods favor.

Beyond appearance, black-framed panels can also offer minor functional benefits. Dark surfaces absorb heat efficiently, which can help snow shed more quickly in colder climates. Manufacturers have also standardized black framing because it aligns with current residential market demand, making these modules more widely available.

While silver-framed panels remain common in commercial and ground-mount installations, black-framed modules have become the residential standard due to their clean appearance and strong curb appeal.

How Many Solar Panels Do You Need to Offset an Electric Vehicle?

/in , /by

Charging an electric vehicle (EV) with solar power is one of the smartest ways to reduce both your energy costs and carbon footprint. In most cases, an EV driven 12,000–15,000 miles per year will use about 3,000–4,000 kWh of electricity annually. To cover that charging entirely with solar, most homeowners need 8–12 solar panels, depending on panel wattage, roof orientation, and local sunlight.

If you already have a solar array, your installer can review your usage and determine whether expanding the system is worthwhile.

Offsetting EV charging with solar not only lowers your operating cost—it also ensures your clean vehicle is powered by clean energy. It’s a simple upgrade that delivers long-term savings and a more sustainable daily drive.
