Factors that Affect Solar Panel Costs in Longmont

There are a number of criteria 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 performs the installation.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That's why it's crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use. The brand and kind of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price 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 extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Most solar companies in Longmont have solar loans, which reduce the initial cost of installing a solar system. It's wise to include the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay off the loan.

Solar Panel Installation Company

The remaining significant cost factor you should keep in mind is the installer you choose. Given the massive popularity of sustainable energy solutions in Longmont, you'll have lots of options to choose from, but each comes at varying price points for labor and equipment. Some companies only sell high-efficiency and high-priced 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 find a company that has the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels

Since the model of solar panels and the company you choose has an impact on your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Installation Process: Get details from your solar installer about the installation process and what to expect, such as when the site survey will be done and what the project timeline is.
  • Solar Panel Brands: Each solar panel brand and type offers varying levels of quality, longevity and efficiency. They will come at different prices as well. The company you choose plays a role in which solar panel brands you have access to.
  • Reputation: Solar companies that have great reviews from their customers and that have been operating for many years in most cases offer quality solar panel installation and expertise.
  • Contract: It's important to read through your solar installer's contract carefully to understand what services they will provide, what the warranty covers and what you can expect about the cost.

EcoWatch's Longmont, CO Solar Cost FAQs

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

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

Is cost the most important thing to think about when buying solar panels?

The initial cost is a key factor to consider, but whether it's the most important for you depends on your reasons for going solar. In cities where rooftop space is limited, efficiency can trump the cost. Other factors that are important to take into account are the quality and durability of your solar panels.

Does Longmont have a net metering program?

Most states have net metering programs of some kind. Through these, you can get paid for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How often do you have to replace solar panels?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
