Colorado’s unofficial slogan proudly claims that the state enjoys “300 days of sunshine a year“. This tremendous solar potential has been put to good use: the state comes in 14th among US states for total installed solar capacity with 1.7 GW of solar installed, and this number is set to more than triple over the next five years, to 5.6 GW. If you’re keen to get in on a piece of the action yourself, there has never been a better time to invest in a solar installation for your Colorado home or business, especially with the generous financial incentives available right now.

But whether you’re looking to cut down on your carbon footprint, or simply want to save on utility bills, picking a good solar company is key. While there are plenty of solar companies operating in Colorado (173 of them, to be exact!) it can be hard to determine which one would best suit your specific needs. Here, we have an in-depth comparison of eight of the most well-known solar companies in Colorado. Of course, there’s one which we think comes out on top – read on to find out which!

Sunsense Solar

Sunsense Solar has been an active member of Colorado’s solar industry for over 30 years, back when solar energy was still a budding new technology. The company was one of two solar installers involved in Colorado state’s SMPA Solar Community Project, which featured the largest community-owned solar garden in the nation at the time.


Sunsense Solar has their headquarters in Carbondale, Colorado. They mainly serve customers in Western Colorado.

Solar Energy in Colorado

Colorado is exceptionally well-suited to renewable energy production. The state’s wide, windswept plains make for great wind farm locations, and the plentiful sunlight it receives year-round also makes solar energy an extremely viable energy source.

And yet, whilst the state is sitting at a respectable 14th out of all US states in terms of installed solar capacity, it has relatively weak regulations and financial incentives for solar power. There are no state-wide solar incentives, and its renewable energy adoption requirements currently lag behind that of leading US states. Colorado also has abundant reserves of fossil fuels and cheap electricity costs, which makes large-scale investment in solar energy look less attractive in comparison. Installing solar energy for your Colorado home or business is still clearly a great investment given the state’s natural sunshine, but more can be done at the state policy level to really push solar energy adoption forwards.

Laws and Regulations

Colorado is one of the first US states in the country to adopt a Renewable Portfolio Standard (RPS) via a public vote. State voters initially approved a regulatory policy in 2004 which required utilities to source 20% of their electricity from renewable sources by 2020. This requirement was later raised to 30% in a House Bill passed in 2015, and in 2019 a further mandate was added requiring utilities serving 500,000 or more customers in the state to source 100% clean energy by 2050. This puts the state firmly in the middle of the pack when it comes to solar regulations, compared with many other US states such as California and New York requiring utilities to produce 100% renewable energy by 2045.

Colorado has also enacted legislation mandating a 10% low-income carve out for Community Solar Gardens in the state in 2010. This means that in addition to encouraging solar adoption by allowing utilities to set up Community Solar Gardens, which provides renewable energy to paying subscribers in the nearby community, 10% of the capacity of these gardens are provided to qualified low-income residents at no out-of-pocket cost.


Colorado is one of the few US states which do not issue a specific solar installation license. Solar companies are required to hold a state Electrical Contractor license, but a small number of Colorado counties also enforce their own solar-specific county licenses on top of that requirement. El Paso county, for example, also requires solar companies operating in the region to hold an El Paso solar license.

Apart from these required state and county licenses, many solar companies in Colorado also possess a NABCEP solar certification, most commonly the NABCEP PV Installation Professional Certificate. These certificates are issued by the North American Board of Certified Energy Practitioners to highly-experienced solar installers after they pass a set of examinations. NABCEP certificates are the gold standard for quality in the solar industry, and we highly recommend keeping an eye out for this qualification when picking out a solar installer.

Net Metering

Colorado’s 2005 net metering legislation makes it mandatory for the state’s major Investor Owned Utilities (IOU), as well as any municipal and co-op utilities serving more than 5,000 customers, to offer net metering packages to customers. An IOU is even required to equipment eligible customers with a bi-directional power meter, if the customer does not already own one.

How net metering works in Colorado is straightforward: You are eligible for the program if you own a grid-connected renewable energy system, and the energy you generate directly offsets your monthly utility bill. If your solar panels are able to generate more power than you use in a year, your utility would reimburse you for the excess electricity at the end of the calendar year. IOUs reimburse excess power at the average hourly electricity cost that year, while a municipal utility or co-op can set any rate which they “deem appropriate”.

To be eligible, the capacity of your solar installation also needs to be below a certain limit: 120% of your annual average consumption for IOU customers, or a flat 10kW for municipal utility or co-op customers.

Tax Credits and Incentives

Colorado, unlike most other states, does not have a state-wide solar tax incentive. Some specific cities and counties do offer local solar incentives, however. For instance, the City of Aspen offers a rebate of $0.75/watt for solar PV installations, and the City of Boulder offers a solar grant of up to 50% of out-of-pocket solar installation costs to qualified low-income residents. The Energy Smart Colorado program also offers a solar PV rebate of up to $500 for solar installations in Roaring Fork Valley and the Gunnison, Eagle, Lake, and Summit counties.

All Colorado residents are also eligible for the federal Solar Investment Tax Credit (ITC). This federal scheme returns 26% of your solar installation costs to you in the form of a federal tax credit. There is no cap to the total tax credit that can be claimed, but the program is set to phase out in a few years. The tax credit would drop to 22% for projects finished in 2023, before being removed altogether from 2024 onwards.


Depending on which part of Colorado you’re in, there can be many potential solar tax incentives and rebate programs available to help you install solar at a discount. We highly recommend talking to a solar installer today if you think you could benefit from powering your property with solar panels. Many good solar companies offer free consultations and quotes, and can also educate you on the specific solar incentives applicable in your region of Colorado. Our list above is a great starting point for your search – why wait to take advantage of the state’s 300 annual days of sunshine!


Does Colorado have a solar tax credit?

There is no state solar tax credit in Colorado currently, but residents do have access to the federal solar investment tax credit. Systems installed in 2021 and 2022 make you eligible for a federal tax credit equal to 26% of the cost of your solar installation. Depending on which Colorado county or city you live in, you might also qualify for local solar incentives. Check out our Tax Credits and Incentives section above for more details!

Is Colorado good for solar?

Yes, Colorado is great for solar! The state enjoys 300 days of sunshine a year, and has a robust net metering program available to almost all residents. Depending on your region, you might also be eligible for city or county-specific solar incentives. We recommend talking to a solar installer operating in your area – they’re usually very knowledgeable about what incentives their customers are eligible for.

What is the average cost of solar in Colorado?

While solar costs can vary wildly depending on the specifics of your property, what types of products you use and which company you go with, online solar industry websites typically estimate the cost at between $2.51 and $3.60/watt. This roughly works out to between $13,302 and $17,998 for the average-sized installation. Shop around for solar quotes from a few different companies operating in your neighborhood for a better idea of how much a solar installation would cost for your property!

Do you need a license to install solar in Colorado?

Yes, all solar companies operating in Colorado are required to hold a state Electrical Contractor license. A few counties in the state also require installers to have an additional county-specific solar installation license.
