Factors that Affect Solar Panel Costs in Maine
The cost of installing a solar system in Maine can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power production require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,760.There are many different solar panel brands and the one you choose also affects the cost. Typically, the brands that are more efficient tend to also be more expensive. In addition, the type of equipment you choose can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Most solar installers in Maine provide solar loans, which reduce the initial cost of installing solar.When estimating your overall cost, you should also calculate the interest you’ll pay if you choose to go with a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.
Solar Panel Installation Company
A final factor to consider when trying to estimate the cost of solar for your home or business in Maine is the company you choose to install your solar panel system. As with choosing a company to renovate your kitchen, for example, there’s no shortage of solar installers that provide a range of services for different budgets.Companies that only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and choose a company that has the products, warranties and services you’re looking for and also is within your budget.

How much does it cost to install solar panels in Maine?
The average cost of solar panels in Maine is about $18,800 for a 5-kW system and $37,600 for a 10-kW system before the ITC, but the actual cost will depend on things like the kind of solar panels you want, what size system you need and how much energy you consume.
Is cost the most important thing to consider when buying solar panels?
The upfront cost is a crucial factor to consider, but whether it’s the most important for you depends on why you decided to go solar. In areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.
Is switching to solar power worth it?
Solar panels can be a beneficial investment for many homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already fairly low, solar panels might not be for you.
How many solar panels do I need to power my home?
To figure out what solar panel system size you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
