FAQ

Common Questions

Find answers to questions Colorado homeowners and businesses ask us regularly.

How long does a typical solar installation take?

The entire process from consultation to grid connection typically takes 4-8 weeks, with most time spent on permitting and utility approvals. We'll provide a timeline specific to your project during the consultation.

Do you handle permits and inspections?

Yes, completely. We manage the entire permitting process with your local jurisdiction, coordinate all required inspections, and handle utility interconnection applications. You won't have to worry about paperwork or dealing with city departments—that's our job. All costs are included in our project estimate.

What size solar system do I need?

System size depends on your annual energy usage, roof size, and sun exposure. During your free consultation, we review your utility bills and perform a site assessment. We then use professional design software to calculate the optimal system size. Most Colorado homeowners benefit from a 6-10 kW system, but yours will be custom-designed for your specific needs.

Does solar work well in Colorado winters and cloudy days?

Absolutely. Colorado has about 300 days of sunshine per year—among the best in the nation. Solar panels work on cloudy days too; they just produce less. Interestingly, solar panels are more efficient in cooler temperatures, so Colorado winters can actually be productive. We design systems accounting for seasonal variations, so you'll generate power year-round.

What is the federal solar tax credit and how much can I save?

The federal Investment Tax Credit (ITC) allows you to deduct 30% of your solar system costs directly from your federal taxes. For a $30,000 system, that's a $9,000 tax credit. This significant incentive is one of the biggest reasons solar makes financial sense. We help you understand how to claim the credit on your tax return.

Does Colorado have state-level solar incentives?

Colorado offers several state-level benefits. Many utilities provide net metering, allowing you to sell excess electricity back to the grid at your retail rate. Some local jurisdictions offer additional rebates or expedited permitting for solar. We research all available incentives for your specific location and utility company and include them in your financial analysis.

How much money can I save with solar?

Savings depend on your current electricity rate, system size, and usage patterns. On average, Colorado homeowners save $10,000-$30,000 over 25 years. Most systems pay for themselves in 6-9 years through energy savings, then generate free electricity for the remaining 16+ years of their lifespan. We provide a detailed financial analysis showing your expected savings during the consultation.

What is the payback period for solar in Colorado?

Most Colorado homeowners see payback in 6-9 years, depending on system size, your electricity rates, and available incentives. After payback, you enjoy 16+ years of essentially free electricity. When combined with the federal 30% tax credit, many systems break even even faster. We calculate your specific payback period during the free consultation.

Do solar panels increase my home's value?

Yes. Studies show homes with solar systems sell for an average of 4% more than comparable homes without solar. Buyers value the lower electricity costs and energy independence. If you finance your solar system, the energy savings often exceed your monthly payment, creating immediate positive cash flow. Solar is viewed as a valuable home upgrade.

Will my HOA allow solar panels?

Colorado law (HB 21-1455) protects your right to install solar even with an HOA. HOAs cannot unreasonably deny solar systems, though they may have reasonable aesthetic requirements. We work with your HOA if needed to address any concerns. Most HOAs approve solar systems once they see the benefits and professional design. Let us guide you through the process.

Do I need to be home during installation?

You don't need to stay home the entire time, but we recommend someone be present at the start so our team can do a final site review and discuss the day's work. After that, you can leave for the day. We'll secure your property and communicate with you about progress. For final inspection and system testing, it's helpful to be present so we can show you how to monitor your system.

How long is a typical system under warranty?

Solar panels typically come with a 25-year performance warranty. Inverters usually have a 10-15 year warranty, sometimes extendable to 25 years. Balance-of-system components like wiring and mounting hardware have 10-year warranties. We recommend purchasing extended inverter warranties for long-term peace of mind. All warranty details are clearly outlined in your proposal.

What happens after installation — do you provide monitoring?

Yes. We provide monitoring setup with most systems so you can track energy production in real-time via app or web portal. We review your system's performance regularly and alert you to any issues. Most modern systems automatically report problems, so issues are caught early. We're here for support long after your system is up and running.

Do you offer financing?

We work with several financing partners to offer flexible options: cash purchase, loans, and leases. Many homeowners finance their solar systems and find that monthly loan payments are lower than the electricity savings, creating immediate positive cash flow. We can model different financing scenarios so you choose what works best for your situation.

Can I add battery storage like a Tesla Powerwall?

Absolutely. Battery storage is becoming increasingly popular in Colorado. You can add it during the initial build or retrofit it later to an existing system. Batteries provide backup power during outages and allow you to use more of your solar energy instead of selling it back to the grid. We design systems with future battery compatibility in mind.

What's the difference between string inverters and microinverters?

String inverters convert DC power from multiple panels into AC power, and are more cost-effective for large, unshaded roofs. Microinverters are attached to each panel individually, offering better performance if shading or roof orientation varies. Each has pros and cons. We recommend the best option based on your roof layout, shading, and budget.

What happens during a power outage — will I still have power?

Standard grid-tied systems without battery backup will not provide power during an outage—this is a safety feature to protect utility workers. However, with battery storage (like a Powerwall), you'll have backup power for critical circuits. We can design systems to include backup capability if that's important to you. Many Colorado homeowners are adding batteries for this security.

How does net metering work in Colorado?

Net metering lets you sell excess solar electricity back to the grid at your retail electricity rate. During the day, your system produces more than you use; this extra power goes to the grid and offsets your account. At night or on cloudy days, you draw power as needed. You pay only the net difference. Most Colorado utilities support net metering, though rules vary by utility.

What's the difference between on-grid and off-grid solar?

On-grid (grid-tied) systems stay connected to utility power, are more affordable, and let you use net metering. Off-grid systems operate independently and require battery storage for nighttime power. Off-grid requires larger systems and more batteries, making it significantly more expensive. Most Colorado homeowners benefit from on-grid systems. Off-grid is mainly for remote properties without utility access.

Can I expand my system later if I add an EV or battery?

Yes, absolutely. We design systems with future expansion in mind. If you add an electric vehicle or battery storage later, your inverter and electrical infrastructure can typically support additional panels. Expansion is usually straightforward and cost-effective. Tell us about your future plans during consultation so we size everything accordingly.

How do panels perform at altitude in Colorado?

Higher altitude is actually beneficial for solar panels. The thinner atmosphere means less light scattering, so panels receive more direct solar radiation. Combined with Colorado's abundant sunshine and cool temperatures (which make panels more efficient), mountain properties often have excellent solar potential. We use detailed modeling to account for your specific altitude and location.

What brands and equipment do you use?

We partner with industry-leading manufacturers including Enphase, SolarEdge, and tier-one panel brands. We select equipment based on reliability, warranty coverage, and performance for Colorado's climate. During your consultation, we'll discuss equipment options and their pros/cons so you can make an informed choice that fits your budget and needs.

How long do solar panels last?

Quality solar panels last 25-30+ years. Most come with 25-year performance warranties guaranteeing they'll produce at least 80% of their rated output after 25 years. Many continue working well beyond that. Inverters typically need replacement after 10-15 years, but we account for that in long-term planning and discuss replacement options upfront.

What happens if a panel is damaged or fails?

Modern solar panels are extremely durable. Manufacturer warranties cover defects and most failures. If a panel is damaged by weather, hail, or accident, your homeowner's or business insurance typically covers it (treat it like any roof damage). We can replace individual panels quickly, and your system continues operating while one panel is out of service.

Do I need a new roof before going solar?

Not necessarily, but it's good timing. If your roof is near end-of-life (15+ years old), you might consider replacing it before adding solar. A new roof prevents costly panel removal later. During your free site assessment, we'll evaluate your roof's condition and honestly advise whether replacement makes sense for your timeline and budget.

How do I clean my solar panels?

Most panels are self-cleaning—Colorado rain and snow do a good job. If you live in a dusty area, occasional gentle rinsing with a garden hose helps. Avoid abrasive scrubbing or harsh chemicals. In most cases, minimal cleaning is needed. Heavy snow will melt on its own and won't damage panels. We provide maintenance guidelines with every project.

Do I need to maintain my solar system?

Solar systems require minimal maintenance. No moving parts means very little can break. Annual inspections are recommended to check electrical connections and overall system health. We offer maintenance plans that include monitoring, inspections, and prompt support if anything needs attention. Most homeowners spend almost nothing on maintenance over 25 years.

What happens if a tree grows and shades my panels later?

Shading significantly reduces solar production, so during initial design we assess trees, buildings, and other potential shade sources. If a tree grows unexpectedly, you have options: trim the tree (often the simplest solution), add more panels in unshaded areas, or upgrade to microinverters that minimize shading impact. We monitor your system and alert you to any performance drops.
