Factors that Affect Solar Panel Costs in Williamson

Even though the average cost of a solar system in Williamson is $9,665, your actual cost may be higher or lower than that. There are many factors that can have a major impact on the cost of a residential solar panel installation. Below are some of the more important things to consider.

Solar Equipment

When it comes to estimating the price of a solar system in Williamson, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy consumption, which you can gauge by looking at past power bills. Your total cost can increase by around $2,610 for each additional kilowatt you need. There are many different solar panel brands and the one you pick also changes the cost. Generally, the brands that are more efficient tend to also be more expensive. Additionally, the type of equipment you choose can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for solar panels in cash is too expensive, solar loans are a popular option because they decrease your upfront costs and let you pay for your system over five to seven years on average. You'll have to consider the long-term cost of financing options, 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 getting a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

The last major cost factor you should take into consideration is the installer you choose. Given the massive popularity of sustainable energy solutions in Williamson, you'll have a great number of options to choose from, but each comes at varying price points for labor and equipment. The size of the company can sometimes play the most considerable role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to more resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

How to Save on Solar Panels

There are a large number of companies to choose from in Williamson, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be tough, so here are some tips to help you decide:

  • Warranty: An all-inclusive, 25-year warranty can help keep your solar system running for a long time and save you money on repairs and maintenance.
  • Contract: Though reading through a contract can be tedious, it's important to do it thoroughly so you can be sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
  • Reputation: Your solar installer should have a solid reputation as a company and have proven 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 past customers.
  • Solar Panel Brands: The type of solar panel you want to get plays a part in which company you should go with, since different companies provide different panels.

EcoWatch's Williamson, AZ Solar Cost FAQs

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

The average cost of solar panels in Williamson is about $13,050 for a 5-kW system and $26,100 for a 10-kW system before the ITC, but the actual cost will depend on certain factors like the kind 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 Williamson?

Leasing solar panels can be an option if you are unable to pay upfront or secure a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your property value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.

How will having solar panels impact the value of my home?

Solar panels can increase the value of your property by about 4%, according to research done by Zillow. The average home value in Williamson is currently $321,545, which means you could be looking at a value of about $13,183 more than houses without a solar system. The specific figures will vary, but most experts agree that installing solar panels in Williamson is a worthwhile investment.

How often do you have to replace solar panels?

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