If you’re a Colorado homeowner who wants to lower their electric bill and carbon emissions, rooftop solar could be the solution for you. Let’s dive into Colorado solar panel costs, savings, and more to see if solar panels are right for you.


How much does it cost to install solar panels in Colorado?

Going solar in Colorado costs $3.41 per watt on average, with the average-sized installation costing $17,799. After the clean energy tax credit is applied, the cost works out to be about $12,459. 

However, not every house will need a 4.9 kW installation. The chart below shows the average cost of a home solar installation based on different common system sizes:

The cost of solar panels in Colorado is higher than the average price of residential solar across the United States, which is around $3.03 per watt. However, this is because the average solar system in Colorado is smaller than the national average of 7.2 kW, making the cost per watt higher. 

You can think of it like buying a bulk pack of paper towels versus a standard one. With the bulk pack, the total cost is higher, but the price per roll of power towels is lower, as the costs of packaging and shipping are spread across more rolls. The same goes for solar — larger systems have a lower cost per watt because the costs of permitting, inspections, and labor are spread across more watts of solar.

Factors that affect the cost of solar panels in Colorado

No two solar projects are the same. The cost of a solar panel installation in Colorado will vary depending on your home’s electricity usage, the type of solar panels you buy, the solar company you choose, and the solar incentives available in your area.

How much electricity your home uses

Homes that use more electricity will need more solar panels to cover their energy needs. If you have more people living in your home and more electric appliances, it’s likely that you’ll need a bigger system.

According to data from the Energy Information Administration (EIA), a typical home in Colorado uses about 662 kilowatt-hours (kWh) per month. With an average electric rate of $0.15 per kWh, most Colorado homeowners are paying just over $105 for electricity each month.  The table below outlines how much solar you need to buy to cover different electric bills:

The good news is that the bigger your energy bill, the more money you can save with solar panels. If you’re nervous about paying more for a bigger system size, the high savings will contribute to a shorter return on your solar investment. 

The type of solar panels you buy

There are a few different types of solar panels, but the most commonly used for home solar are monocrystalline panels. The price of solar panels can depend on the brand used. If your installer is using high-quality Tier 1 solar panels, they may cost a bit more per watt.

Most solar panels on the market today have efficiency ratings between 19% and 21% and an output of 370 to 400 watts of power in ideal conditions – with some brands offering panels with outputs as high as 440 W. 

Just keep in mind that if you want bigger, more efficient solar panels, you’ll likely be paying a higher price. You can seek out cheaper solar panels; just be sure you aren’t sacrificing quality for a low price.

How do I find affordable solar panels?

The solar installer you chose

When looking for a solar installer, we recommend getting at least three quotes to compare prices. This way, you can also see what solar equipment is being used, the system size you’re being quoted for, and – most importantly, the cost.  

But don’t just choose the cheapest quote you find. Cheaper isn’t always better, as it may be a sign that the installer is using low-quality equipment or poor installation practices. Take a close look at the solar products being used and the company’s reputation, and find one that fits your budget! The more quotes to compare, the better.
