Factors that Affect Solar Panel Costs in St. Johnsbury
For many St. Johnsbury homeowners, the decision to install solar panels comes down to cost. However, the range of solar installation costs can be quite wide in St. Johnsbury, with typical prices between $20,000 to $40,000. There are several factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
When it comes to estimating the price of a solar system in St. Johnsbury, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are primarily based on your home’s energy usage, which you can determine by looking at past electricity bills. Your overall cost can increase by about $3,850 for each additional kilowatt you need.There are many different solar panel brands and the one you pick also changes the cost. Usually, the brands that have better efficiency tend to also cost more. In addition, 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
Most solar installers in St. Johnsbury offer solar loans, which reduce the initial cost of installing solar panels.However, the interest on solar loans also increases your total costs, so it’s important to include that in your estimate as well. You can always reduce the total you pay in interest and possibly even your APR by putting more money down.
Solar Panel Installation Company
The solar company you choose will influence your total cost to adopt solar power. Different companies will charge different amounts for the equipment and labor.Larger national companies usually have lower costs, but some local companies compete with them by offering 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 vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because picking a company can be a tough decision, we have some tips to help you, such as:
- Installation Process: Make sure you’re aligned with the installer regarding how the installation process will go and what needs to be done before your solar panels are installed, such as updating or replacing your electrical system or roof.
- Solar Panel Brands: Not all solar companies offer the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you choose.
- 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 most likely has a good reputation and is qualified to do the job well. Another way you can research your installer’s reputation is by reading reviews.
- Warranty: Each company may offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
