Factors that Affect Solar Panel Costs in St. Thomas
The cost of installing a solar system in St. Thomas can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The most significant one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. For that reason, it’s important to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use.The brand of solar panels and equipment you choose is another factor that will substantially affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Further, solar equipment consists of more than just the solar panels themselves. You’ll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when researching a solar system that’s in your budget.
Solar Financing Terms
Most solar installers in St. Thomas offer solar loans, which reduce your upfront costs of installing a solar system.However, the interest on solar loans also adds to your all-in costs, so it’s vital to include that in your estimate as well. You can always lower the total you pay in interest and possibly even your APR by putting more money down.
Solar Panel Installation Company
The solar installer you go with to handle your switch to renewable energy can have an effect on your total costs. There are about 3 solar installation companies operating in St. Thomas, and each can charge different amounts for labor and equipment.You may see national solar installers that have lower prices because of their bigger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

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 keep in mind, such as:
- Solar Panel Brands: The type of solar panel you’d like to install plays a role in which installer you should go with, since different companies provide different panels.
- Warranty: Warranties that cover panel repairs and maintenance over a long period of time such as 25 years are the best you can get in the business, and offering such a warranty is one indication of a good company.
- Reputation: Your solar installer should have a good 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 positive reviews from previous customers.
- Installation Process: Make sure you’re aligned with the installer in 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.
