Factors that Affect Solar Panel Costs in Capital

There are a number of criteria that can play into your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power production require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,730. The brand and type of equipment you get 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 a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to more savings over time. Also, if you want add-ons 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 Capital to be too costly, even if the investment pays off over time. Thankfully, almost every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also lead to a higher cost over time because of interest. You'll have to consider the long-term cost of loans, including the total interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the original cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

The solar company you select will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Capital are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since choosing a company can be a tough decision, we have some tips to help you, such as:

  • Installation Process: Homeowners should make sure they know how exactly the installation process will go, as well as important factors like the project completion timeline.
  • Solar Panel Brands: The type of solar panel you need to get plays a part in which company you should opt for, since different companies offer different panels.
  • Reputation: Your solar installer should have a good reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from previous customers.
  • Contract: Even though reading through a contract can take a lot of time, it's important to do it thoroughly so you can be sure you understand what services your solar company will provide and the terms of the warranty.

Is making the switch to solar worth it?

Whether or not solar panels are worth it depends on some different factors like local electricity rates and how much direct sunlight your roof gets.

How long do solar panels last in Capital?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time.
