Factors that Affect Solar Panel Costs in Plymouth
For many Plymouth homeowners, the decision to adopt solar energy rests on cost. However, the range of solar installation costs can be quite wide in Plymouth, with typical prices between $20,000 to $40,000. There are various factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
One of the most significant 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 energy your household uses, the larger your system will likely need to be. You can expect to spend about $4,220 per kilowatt in Plymouth.The type of solar panels and equipment you want is another factor that will considerably influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Further, solar equipment goes beyond just the solar panels themselves. You’ll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking for a solar system that falls within your budget.
Solar Financing Terms
Most solar companies in Plymouth provide solar loans, which reduce the initial cost of installing solar panels.However, the interest on solar loans also adds to your all-in costs, so it’s important to take that into consideration as well. You can always reduce the total you pay in interest and possibly even your APR by making a larger down payment.
Solar Panel Installation Company
A final consideration when trying to evaluate the cost of solar for your home or business in Plymouth is the company you choose to install your solar panel system. As with choosing a company to renovate your kitchen, for example, you’ll have no shortage of solar installers that provide a range of services at different price points.Larger national companies typically have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
The solar installer you go with will influence not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should keep in mind, such as:

- Reputation: Solar companies that have great reviews from their customers and that have been operating for many years in most cases provide quality solar panel installation and expertise.
- Installation Process: Make sure you’re aligned with the company regarding how the installation process will go and what needs to be done before your solar panels are installed, such as repairing your electrical system or roof.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and how much efficiency they need. While there are many options for which model of solar panel you can get, not every company will have the exact one you may want or need, so be sure to ask for their list of options before making your decision.
