Factors that Affect Solar Panel Costs in Windham
There are several factors that can influence your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
The size of the solar energy system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $4,220. 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. However, more efficient panels could save you more over time on your electric bills. Additionally, add-on products, like solar batteries, can bring your total well above the Windham average.
Solar Financing Terms
Many homeowners find the average cost of solar in Windham to be too steep, even if the investment pays off over time. Thankfully, nearly every solar company in the area offers financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also lead to a higher cost over time due to interest.It’s a good idea to factor the interest you’ll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it’ll take to pay off the loan.
Solar Panel Installation Company
The last major cost factor you should keep in mind is the installer you choose. Given the booming popularity of clean energy solutions in Windham, you’ll have a great number of options to choose from, but each comes at various price points for labor and equipment.You may see national solar installers that have lower prices because of their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

How to Save on Solar Panels
The company that does your system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because selecting a company can be a challenge, we have some tips to help you, such as:
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to do the job well. Another way you can look into your installer’s reputation is by reading reviews.
- Contract: Read the contract terms carefully to make sure you understand how much it will cost, project timeline rebates and warranties.
- Installation Process: Make sure you’re on the same page with the installer regarding 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.
- Solar Panel Brands: Different companies will offer different brands and kinds of panels. If you prefer a specific brand, make sure the solar panel installer you’re considering has it.
