Factors that Affect Solar Panel Costs in Maine

For many Maine homeowners, the decision to install solar panels rests on cost. However, the range of solar installation costs can be quite wide in Maine, with typical prices between $20,000 to $40,000. There are a few factors that considerably influence the price you’ll pay, which we'll go over below.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. Because of that, it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use.The brand and type of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Maine to be prohibitively expensive, even if the investment pays off over time. Thankfully, nearly every solar company in the area provides financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also lead to a higher cost over time due to interest.While solar loans make going solar more accessible for Maine homeowners, they can also add to the total you pay for your system due to interest. If you put down a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

Lastly, the company you hire to install your solar system can influence your pricing. Maine’s solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Maine are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since selecting a company can be a tough decision, we have some tips to help you, such as:

  • Solar Panel Brands: Each solar panel brand and model has varying levels of quality, longevity and energy efficiency. They will come at different prices as well. The company you choose has an impact on which solar panel brands you have access to.
  • Warranty: A high-quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: It’s important to read through your solar installer’s contract well to understand what services they will provide, what the warranty covers and what you can expect about the cost.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to do the job well. Another way you can verify your installer’s reputation is by reading reviews.

EcoWatch's Maine, NY Solar Cost FAQs

What is the average cost of installing solar panels in Maine?

The average cost of solar panels in Maine is about $18,250 for a 5-kW system and $36,500 for a 10-kW system before the ITC, but the real cost will depend on certain factors such as the kind of solar panels you want, what size system you need and how much energy you consume.

What other factors should I consider other than cost when buying solar panels?

Cost is a crucial factor to consider, but whether it’s the most important for you depends on your goals for going solar. In areas where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.

How much can I save on energy bills after switching to solar?

It is possible to erase your electricity bills with solar panels, but for most homeowners in Maine, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.

How many solar panels do I need to power my home?

The exact number of solar panels you need depends on your household energy consumption and the amount of sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to cover their typical energy usage.
