How To Choose the Best Solar Company in Thornton

The cost and efficiency of solar panels often rely on which company mounted them. Here are some key items to remember while shopping for a solar specialist.

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 their own solar professional if they choose. Solar providers can also earn accreditations from trade groups and standards organizations. The top ones in the industry come from the North American Board of Certified Energy Practitioners. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Thornton

The kind of solar panels you select decides how much power you can generate. Monocrystalline panels cost more but give you the best performance. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

If you'd like to charge an electric car or use your solar power in cloudy weather, you can pay extra for accessories. By choosing the right components, you can make your system more efficient and user-friendly. Not all solar companies include these extras, so look for a provider that installs them if it's crucial for you.

Generally speaking, it costs about $19,900 for a five-kilowatt solar array in Thornton. This table shows more specific pricing information for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$2,002
Solar Polycrystalline$1,562
Thin-Film$913
Solar Battery$1,281
Solar Home EV Charger$4,805

Financing Solar Energy in Thornton

Solar contractors offer multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar loans, solar leases, cash payments and power purchase agreements (PPAs). Most solar experts recommend paying cash or using a solar loan. Cash payments demand a large up-front sum, but they help you avoid 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. Similar to a home or auto loan, you'll pay a set monthly rate with as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) permits you to pay a monthly rate determined by the energy you use, as with an electric bill. We typically don’t recommend these two options because you won't own the panels and are disqualified from using solar incentives. Look for companies that offer several payment plans to find the right fit for your budget.

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

A 26% federal tax credit applies to new home solar systems purchased through 2032. Additional incentives may be available through city and state governments, usually in the form of rebates and special financing programs.

Frequently Asked Questions About Solar in Thornton

How much energy and money could I save per year by switching to solar?

On average, Thornton homeowners pay roughly $968 per year on energy bills. Once you repay your solar array, you could reduce your costs by $1,040.64 per kilowatt you produce.

How widespread is solar energy in Thornton?

Yes, solar energy is on the rise in Thornton. Some homes already benefit from solar power on-site or through utility grids, and they're fortified by a state solar economy with 7174 jobs and counting.

Should I anticipate a property value increase after installing solar panels?

Yes, new solar systems translate to higher property values according to the National Renewable Energy Laboratory (NREL.) Homeowners could project a $20 property value increase for each dollar they save on energy. Therefore, $600 in energy savings could boost your property value by $12,000.

Could I still use solar power if I live in a rainy, dark, or wooded area?

Solar panels could still operate in bad weather. Your technician will orient your panels to absorb the most sunlight possible. They might also recommend a backup battery to keep your system working at its best.

What can I do to predict my home's solar viability?

To determine your home's solar readiness, there's no substitute for a comprehensive quote from a local solar provider. However, you can use the PVWatts tool for a simple solar viability estimate based on public data, including system size, local weather and topography, panel efficiency, and tree cover.

What's a Thornton solar panel's average lifespan?

Today's solar installations are incredibly durable, lasting up to 25 years. Monocrystalline panels and other high-end models tend to last longer than cheaper models.

How does "net metering" work, and do I need to participate?

Most utilities and states provide net metering programs, and some require homeowners to join. Once you sign up, you can obtain a check or bill credit for any surplus electricity you generate and send to the grid. Generally, power companies reimburse solar homeowners at a wholesale or "avoided-cost" rate.

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

Even the most respected Thornton solar installers will have both glowing and negative reviews. To make the most informed selection possible, focus on these indicators to know if a company isn't worth your attention:
  • Pressuring you into signing a contract
  • Not being straightforward about training and credentials, references, warranties and cost
  • Limited or no customization
  • Superficial, rushed site evaluation
  • No business filing with your local secretary of state
