Factors that Affect Solar Panel Costs in Waltham
Cost is usually one of the most important factors for homeowners who want to invest in solar. There are a few primary factors that will push your cost above or below the average in Waltham: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.
One of the most important factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to pay around $2,940 per kilowatt in Waltham. There are many different solar panel brands and the one you pick also changes the cost. Typically, the brands that offer higher efficiency tend to also cost more. Plus, the type of equipment you're looking to get can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
If paying for solar panels in cash is too expensive, solar loans are a solid route because they reduce your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years. Although solar loans make switching to solar energy more accessible for Waltham homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
The final key cost factor you should keep in mind is the installer you choose. Given the booming popularity of clean energy solutions in Waltham, you'll have plenty of options to choose from, but each comes at varying price points for labor and equipment. The size of the company can sometimes play the most significant role in your costs. Larger national companies, like SunPro and Sunrun, often have lower prices due to access to more resources and bulk 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 lower to compete with bigger names.

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. 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 respected certification organization for sustainable 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 look into your installer's reputation is by reading reviews.
- Contract: Read the contract terms carefully to make sure you understand the cost breakdown, project completion timeline incentives and warranties.
- Solar Panel Brands: The type of solar panel you want to install plays a role in which installer you should opt for, since different companies provide different panels.
- Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be done and what the project timeline is.
