Factors that Affect Solar Panel Costs in Boulder

There are many factors that can influence your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to pay about $2,690 per kilowatt in Boulder. The brand and type of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Boulder to be prohibitively costly, even if the investment pays off over time. Thankfully, almost every solar installer in the area provides financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also result in a higher cost over time because of interest. You'll have to consider the long-term cost of loans, including the amount of interest you'll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs significantly.

Solar Panel Installation Company

The final major cost factor you should consider is the installer you choose. Given the massive popularity of green energy solutions in Boulder, you'll have many options to choose from, but each comes at varying price points for labor and equipment. Companies that only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It's best to do some research and decide on the company that offers the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you pick the right company for you, here are some tips to keep in mind:

  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, longevity and efficiency. They will come at different prices as well. The company you choose has an impact on which solar panel brands you have access to.
  • Contract: It's important to read your solar installer's contract thoroughly to understand what services they will provide, what the warranty covers and what expectations you should have about your solar system's energy production.
  • Warranty: If you care about the longevity of your solar system, making sure your company offers a 25-year, all-inclusive warranty can help put you at ease.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to install your solar system. Another way you can check your installer's reputation is by reading reviews.

EcoWatch's Boulder, CO Solar Cost FAQs

What is the average cost of installing solar panels in Boulder?

The average cost of solar panels in Boulder is about $13,450 for a 5-kW system and $26,900 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the type of solar panels you want, what size system you need and how much energy you use.

Is it better to lease or buy solar panels in Boulder?

Leasing solar panels can be an appealing choice, because it often comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

Is it worth going solar in Boulder?

Whether or not solar panels are worth it depends on a variety of factors like the cost of electricity near you and the amount of direct sunlight your roof gets.

How many solar panels do I need to power my home?

To figure out what solar panel system size you need, you need to know how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
