Factors that Affect Solar Panel Costs in Windham
Cost is usually one of the most important factors for homeowners considering investing in solar. There are a few key factors that will push your cost above or below the average in Windham: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of installing solar panels. That’s why it’s important to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use.There are several different solar panel brands and the one you pick also changes the cost. Usually, the brands that offer higher efficiency 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 a solar system out of pocket is too expensive, solar loans are a popular option because they reduce 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 loans, including the amount of interest you’ll pay over the length of the loan. If you can only 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 securing a solar loan with a low interest rate could reduce your costs remarkably.
Solar Panel Installation Company
The last significant cost factor you should consider is the installer you choose. Given the booming popularity of sustainable energy solutions in Windham, you’ll have lots of options to choose from, but each comes at different price points for labor and equipment.The size of the company can sometimes play the most significant role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to greater 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
The solar panel company you go with will be a major factor in determining not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should consider, including:
- Solar Panel Brands: Each solar panel brand and model offers varying levels of quality, longevity and efficiency. They will come at different costs as well. The company you choose has an impact on which solar panel brands you have access to.
- Contract: When reading through your solar company’s contract, ask for clarification about any terms you’re not sure of and make sure you understand what happens in scenarios such as a system component breaking or the company going out of business.
- Warranty: Warranties that provide coverage for defective panels and repairs over around 25 years are the gold standard in the business, and offering such a warranty is one mark of a good company.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to do the job well. Another way you can verify your installer’s reputation is by reading reviews.
