Factors that Affect Solar Panel Costs in Williston
The cost of installing a solar system in Williston can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The biggest one is the size of the system your home needs, and other factors include equipment choices, financing options and the solar company you choose.
Solar Equipment
When it comes to estimating the price of a solar system in Williston, 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 usage, which you can gauge by looking at past power bills. Your total cost can increase by about $3,850 for each additional kilowatt you need.There are several different solar panel brands and the one you choose also changes the cost. Generally speaking, the brands that have better efficiency tend to also cost more. Additionally, the type of equipment you choose can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Most solar companies in Williston offer solar loans, which reduce the initial cost of installing solar.However, the interest on solar loans also adds to your total costs, so it’s important to keep that in mind as well. You can always reduce the total you pay in interest and in some cases even your APR by making a larger down payment.
Solar Panel Installation Company
A final factor to keep in mind when trying to evaluate the cost of solar for your home or business in Williston is the company you hire to install your solar panel system. Similar to choosing a company to install new cabinets, for example, there’s no shortage of solar installers that offer a range of services at different costs.Some companies 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 cost more. It’s best to do some research and decide on the company that provides the products, warranties and services you’re looking for and also is within your budget.

How to Save on Solar Panels
The company that does your solar panel installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since choosing a company can be a challenge, we have some tips to help you, such as:
- Solar Panel Brands: Different companies carry different brands and kinds of panels. If you know you want a specific brand, make sure the solar installer you’re considering has it.
- Installation Process: Make sure you’re on the same page with the installer with regard to how the installation process will go and what you need to do before your solar panels are installed, such as updating or replacing your electrical system or roof.
- Contract: Though reading through a contract can take a lot of time, it’s important to do it fully so you can be sure you understand what services your solar company will provide and the terms of the warranty.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to install your solar system. Another way you can verify your installer’s reputation is by reading reviews.

The average cost of solar panels in Williston is about $19,250 for a 5-kW system and $38,500 for a 10-kW system before the ITC, but the actual cost will depend on certain factors such as the type of solar panels you want, what size system you need and how much energy you consume.
What other factors should I consider other than cost when buying solar panels?
Cost is a crucial factor to consider, but whether it’s the most important for you depends on your goals for going solar. In cities 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 it worth going solar in Williston?
Solar panels can be a beneficial investment for many homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your energy bills are already pretty low, solar panels might not be for you.
How many solar panels do I need to power my home?
To figure out how many solar panels you need, you should find out how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
