Factors that Affect Solar Panel Costs in Windom

Cost is often one of the most important factors for homeowners wanting to invest in solar. There are a few key factors that will push your cost above or below the average in Windom: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.

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 $4,030 per kilowatt in Windom.The kind of solar equipment you choose can increase or decrease your cost by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your electric bills. In addition, extra products, like solar batteries, can bring your total well above the Windom average.

Solar Financing Terms

If paying for solar panels in cash is difficult, solar loans are a popular route because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years.Though solar loans make adopting solar energy more accessible for Windom homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

Lastly, the company you get to install your solar panels can play a role in determining the cost. Windom’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar panel company you choose will influence not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should consider, such as:

  • Reputation: Solar companies that have great reviews from their customers and that have been in business for many years likely provide high-quality solar panel installation and expertise.
  • Solar Panel Brands: Different companies will have various brands and kinds of panels. If you want a specific brand, make sure the solar company you’re considering has it.
  • Contract: Although reading through a contract can take a lot of time, it’s important to do it carefully so you can make sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
  • Installation Process: Homeowners should make sure they understand how exactly the installation process will be carried out, as well as important factors like the project timeline.

EcoWatch's Windom, MN Solar Cost FAQs

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

The average cost of solar panels in Windom is about $20,150 for a 5-kW system and $40,300 for a 10-kW system before the ITC, but the real cost will depend on stuff like the kind of solar panels you want, what size system you need and how much energy you use.

What other factors should I consider aside from cost when buying solar panels?

Cost is a very important factor to consider, but whether it’s the most important for you depends on your reasons for going solar. In areas where rooftop space is limited, efficiency can trump the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Is making the switch to solar worth it?

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 often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can keep using them at a lower efficiency.
