Factors that Affect Solar Panel Costs in Watertown
There are several factors that can influence your 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
One of the most important factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to spend about $3,750 per kilowatt in Watertown.Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Watertown, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Solar panels can save you money on energy bills over many years, but they can also be a big investment. That’s why many Watertown homeowners opt to finance their solar panel systems to make going solar more affordable.Even though solar loans make switching to solar energy more accessible for Watertown homeowners, they can also raise the total you pay for your system due to interest. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar installer you pick will influence your total cost to make the switch to solar energy. Different companies will charge different amounts for the equipment and labor.Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and decide on the company that offers the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels
There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you select the right company for you, here are some tips to keep in mind:
- Contract: Read the contract terms closely to make sure you understand the cost breakdown, project completion timeline incentives and warranties.
- Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you go with.
- Warranty: Warranties that provide coverage for replacement parts and repairs over a long period of time such as 25 years are the gold standard in the business, and offering such a warranty is one mark of a quality company.
- Installation Process: When going solar, it’s necessary to keep an open line of communication with your solar panel company. Confirm that you understand how the installation process will go and the project completion timeline.
