How To Choose the Best Solar Company in Denver

The price and efficacy of solar panels often rely on the provider that installed them. Make your choice based on the following crucial aspects.

Licensing and Training

While electricians and plumbers in Colorado have state-issued licenses from the Colorado Electrical Board or Colorado State Plumbing Board, the state's unique home-rule structure means counties and cities can issue solar contracting licenses if they choose. Look for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar industry's most credible trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Denver

The kind of solar panels you purchase dictates how much energy you can produce. Monocrystalline panels cost more but give you the best performance. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total project price, but they can boost your solar system's efficiency. Not all solar companies offer these add-ons, so look for a company that sells them if it's essential for you.

If you're a resident of Denver and want a five-kilowatt solar energy system, you could expect to pay about $19,900 for materials and labor. See more information on specific component and panel costs in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,173
Solar Polycrystalline$915
Thin-Film$535
Solar Battery$751
Solar Home EV Charger$2,816

Financing Solar Energy in Denver

Choosing the optimal financing plan will impact your overall solar system cost and potential savings. Common payment options include power purchase agreements, loans, cash payments, and leases. Most solar experts recommend a cash payment or using a solar loan. Cash payments demand a large up-front sum, but they save you from paying interest, grant you system ownership, and qualify you for cost-saving incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Like a car or home loan, you'll pay a set monthly rate with potentially $0 down. Solar leases allow you to use your panels for a set monthly rate, while PPAs let you pay only for the energy you use, much like an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Look for installers that offer several payment plans to find the right fit for your pocket.

The table below lists the average payback periods for different capacities of solar systems in Denver.

The IRS allows you to claim a 26% federal tax credit on your new solar panels, so long as you purchase it before 2032. Municipal authorities and utilities might also offer their own financing programs, incentives, and rebates that could save you more money.

Frequently Asked Questions About Solar in Denver

How much money could I save by going solar in Denver?

On average, Denver homeowners shell out approximately $968 per year on energy bills. Once you pay off your solar array, you could save $998.12 per kilowatt you produce.

How prevalent is solar energy in Denver?

Yes, solar energy is gaining popularity in Denver. Some homes already use solar power on-site or through utility grids, and they're supported by a state solar economy with 7174 jobs and counting.

Will solar energy systems boost my Denver home worth?

Yes, a solar PV system will raise your property value. According to the National Renewable Energy Laboratory, for every dollar you reduce on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

What if I live in a heavily-wooded or rainy

Solar panels could still work in cloudy conditions. Your installer will position your panels to absorb the most sunlight possible. They might also recommend a battery backup system to keep your system working at its best.

How long does the solar installation process last?

Your solar job's duration will depend on its size and complexity, as well as Denver's permit and inspection procedures. It could take several weeks to a couple of months on average.

What size should my new Denver solar system be?

The average Denver solar system size is 5.2 kilowatts (kW). However, your final system size depends on your home's power consumption. Your roof size, surrounding shading, and panel model could also impact your final result. A professional solar provider will consider these factors and determine the right array size for your home.

What are some "red flags" to watch for as I research companies?

Even the most renowned Denver solar companies will have both favorable and critical reviews. To make the most informed choice possible, focus on these signs to know if a company isn't worth your attention:
  • Aggressive sales pitch
  • Being evasive about training and credentials, references, cost and warranties
  • "One-size-fits-all" approach
  • Superficial, rushed site evaluation
  • No references or testimonials

What's the difference between a PPA and traditional financing?

A power purchase agreement (PPA) is a contract between you and your provider. They install, own, and maintain the panels, and you buy the generated electricity from them for 10–25 years. There will usually be options to buy out early to own your system and extend the agreement.

In contrast, solar loans can come from specialty lenders, local banks, the government and installer. You'll need to pass a credit check to qualify for most of them. While the upfront costs are greater, and you'll be responsible for maintenance, you'll also have full ownership rights and can apply for many more incentives.
