How to Figure Out if Solar Panels are Worth It in Maine

Solar panels in Maine are very often a good investment that provides homeowners with substantial savings. However, they aren’t for everyone, and jumping into this renewable energy source without assessing your solar viability first could leave you losing money rather than saving it. Below are some factors you’ll want to consider before going solar in ME.

What’s Your Home Electricity Consumption?

Solar panels typically save homeowners money because they help reduce or even eliminate energy bills. As such, the more you spend on your electric bills, the higher the potential for savings and the more you stand to benefit from your panels. In general, homes that consume more than 500 kilowatt-hours are considered good candidates for solar panel installation. You can check your electric bill for usage history to see how much you consume on average. Most Maine homeowners use around 570 kWh per month, which is very low compared to the national average of 893 kWh. While this usage suggests that solar might provide minimal savings, the electricity rate — an average of 16.81 cents — is much higher in Maine than in the rest of the US. Given the high energy rates, most homes will still find solar panels worth the investment, even if they use slightly less than 500 kWh per month.

How Much Is It To Go Solar in Maine?

The total price of solar panels in Maine depends on many factors, including the size of your home, your energy needs, the direction your roof faces and more. The average price per watt is $2.83, well above the national average of $2.66. Since energy consumption is low in Maine, the typical system is just 6 kilowatts, about half of the average elsewhere in the country. Therefore, the total average price is around $12,565 after the federal tax credit is considered. Solar is more valuable in areas where energy needs or electricity rates are high. Although Mainers use far less electricity than most US residents, they pay well above average per kWh, making solar a great option for most homeowners in the area.

What’s the Payback Period for Solar in Maine?

Residential solar systems are pricy no matter where you live, but they almost always pay for themselves over time in energy savings. The time it takes for this to occur is referred to as the panel payback period, and it’s one of the best metrics for determining how suitable your home is for panels. Appropriately-sized systems in Maine pay for themselves in an average of just 10 years, which is below the national average of 12 years. Most Maine systems have a payoff period between 7 and 13 years. Ultimately, this means solar is more valuable in Maine than in most other states. Since panels have a lifespan of 25+ years, the additional 15+ years of electricity generation, after they pay themselves off, totals around $20,786 in Maine, on average. If your payback period is longer than the average, your ROI will be lower.

What Are Average Buy-Back Rates in Maine?

Most states have mandated net metering or an electricity buy-back program. These programs let solar customers produce more energy than they use and sell the excess back to the utility company for a credit to their bill for energy pulled from the electric grid. Net metering is mandated by the Maine Public Utilities Commission, so all solar customers can benefit from it. However, the rate at which the energy is purchased by your electric company is not guaranteed. You should check with your electric company before signing anything, as policies can vary. Some companies might offer the retail rate, which is ideal, while others could use a below-retail rate, which is still good but less beneficial. If you have a non-ideal net metering policy offered to you, you might need to add a battery pack to your solar power system to eliminate your electric bill entirely.

How Much Sun Does Your Roof Receive?

Solar is more valuable in sunny areas, as more abundant sunlight means more energy production, which means more potential savings. Maine receives around 192 sunny days per year, which is below the national average of 205 days. Still, this is typically enough available sunlight to make solar panel installation a worthwhile endeavor. You will, however, need to assess your property on an individual basis. First, you’ll want to look at where your roof faces, as south-facing and west-facing roofs are the best for solar panels in the US. Additionally, trees cover an incredible 89% of the state, and heavy shading on your roof during peak sunlight hours will reduce the value of your panels.³ Shading from buildings and other structures are similarly detrimental.

What’s the Outlook on Solar in Maine?

Maine has always been an environmentally-friendly state, and it currently has lofty Renewable Portfolio Standard (RPS) goals of producing 80% of all energy production in the state via renewable energy sources by 2030. While other clean energy sources like wind power and biomass are used to help reach this goal, solar power is, by far, the leading source of clean energy in the state. Residential solar installations have increased in popularity over the past decade, although growth has been a bit slower than expected. This could be due to the lack of solar incentives available, although there are some statewide incentives. Utility-scale solar and community solar farms have both become wildly popular in the past few years. Overall, solar is looked on favorably in Maine, and the market is expected to continue to grow in the future.

Benefits of Solar Energy in Maine

Going solar in Maine provides many upsides, many of which are financial. We’ll discuss the benefits of going solar in Maine below so you know how solar can positively affect you in the Pine Tree State.

Electricity Bill Savings

The most significant upside to installing solar panels — and the reason they pay for themselves and provide savings — is the reduction they’ll provide on your utility bills. The average Maine homeowner pays $95.77 per month for electricity, which means the right size solar panel system with a good net metering program or solar battery could save you $1,149 every year. Over the lifetime of your panels, they’re expected to save you around $20,786 after they pay themselves off! Your actual savings might end up being even more substantial because energy rates are expected to continue to rise in the future. Installing solar panels basically means you’ll be locking in a lower electricity rate for the 25+ years your panels are expected to last.

Lower Taxes & Access to Other Incentives

The federal government provides a substantial tax incentive via the federal solar tax credit (ITC). The ITC is for 26% of your total solar energy system price, which averages around $4,415 in Maine. This amount is credited to your federal income tax liability for the year your panels are installed. As mentioned above, Maine has a lofty RPS goal of producing 80% of its energy from renewable sources by 2030. To help reach that goal, the state provides a few incentives to make solar conversion more appealing:

• Net Metering: Maine mandates net metering, so all solar customers will be able to route energy to the grid via their inverters and get credited for excess energy their panels produce. The rate at which you’re credited per kWh varies, so check with your power company before signing anything.
• Property Assessed Clean Energy (PACE) Program: Maine takes part in the PACE Program, which makes financing more accessible to prospective solar customers. The program limits your interest rate and your down payment, ultimately making converting more affordable.
• Community Solar: Community solar has surged in popularity in Maine over the past few years. It allows homeowners whose properties aren’t suited for panel installation or who don’t want panels on their roofs to take part in clean energy.
• Property Tax Exemption: Solar panels will bump up your home value, which normally increases your property taxes. The property tax exemption in Maine prevents your taxes from going up just because you install solar panels.

Home Resale Value Increase

Many homeowners don’t realize that solar makes your home more valuable. Research completed by Zillow suggests that the typical home jumps in value by around 4.1%.⁴ In Maine, where the typical property is worth $341,268, that comes out to an average value increase of $13,992.⁵ Your home will only go up in value if you buy your panels with cash or a solar loan option. Solar leases and power purchase agreements (PPAs) are less valuable in most cases in part because they don’t provide a bump in home value.

Clean, Renewable Energy

Given how environmentally conscious Maine residents typically are, one of the most appealing benefits for many residents will not be financial. Converting to solar power reduces your dependence on fossil fuels, which means you’ll be contributing less to global warming and water and air pollution. Plus, your panels provide more energy independence, which means you’ll rely less on your power company and can avoid electricity price hikes.

What to Look Out For When Considering Solar in Maine

While determining if going solar is right for your home is a big first step to take, there are still quite a few more things to consider before you commit to going solar and have your panels installed. We’ll discuss a few additional considerations you should make below.

Upfront Fees

The upfront fees of solar panels will be an important factor for any homeowner, even in Maine, where the average total solar array expense is about half the national average. If you’re looking to keep your upfront investment down, you can choose a cheaper panel brand and avoid add-on products like solar batteries and electric vehicle chargers, which can add thousands to your total. You can also choose a no-money-down or low-down-payment loan, which is often available via Maine’s PACE Program.

Payback Period

The estimated solar panel payback period for your property is one of the best metrics you can use to determine the value of panels on your home and estimate your long-term savings. The typical payback time frame in Maine is between 7 and 13 years. If your payback period is longer than 13 years, you’ll still almost certainly save money, but your overall ROI will be lower than average and it will take longer to recuperate your initial investment.

Net Metering Policies in Maine

Net metering is an enormously beneficial program that allows many solar customers to substantially offset or even eliminate their electric bills without having to install a solar battery. While Maine does mandate net metering, the rate at which you’re credited for excess power isn’t set by the state. You should check with your utility provider before committing, and if your credited rate is below the retail rate, you might need to add battery storage to your home solar project to eliminate your energy bills.

Pending Policies & Changes to Incentives

The solar industry in Maine is still expanding, and with changes in the future could come additional incentives, alterations to or loss of existing incentives and new rebate programs. It’s usually not financially worth it to wait for better incentives to come along, but you should do some research and look for updated policies and programs before going solar in Maine.

Weather & Climate in Maine

The available sunlight in Maine is generally conducive to solar energy. The state as a whole receives 192 sunny days per year, which is often plenty for homeowners to see substantial value in their solar panels. Solar is best in areas closer to the equator, so some residents worry that the northern location of Maine and the abundant snowfall will make solar a poor choice in the area. However, electricity flows more quickly in the cold, so the frigid winters will still supply decent energy production. Snow coverage will reduce panel efficiency, but it will also naturally keep your panels clean to maximize production when it’s sunny. Cloudy days will reduce panel efficiency as well, but there’s usually plenty of sun in Maine to offset the loss of production when it’s cloudy.

Companies Pushing Solar Leases or PPAs

Finally, you should be aware of some less reliable solar panel installation companies in the area and some solar scams that, unfortunately, occur regularly. First, be on the lookout for companies advertising “free panels.” Solar panels are never really free, and this is a marketing tactic to get you to sign a lease or power purchase agreement (PPA). These options should typically be avoided, as they don’t provide the same savings as a purchase or solar loan, they don’t increase your property value and they don’t let you take the federal tax credit. Additionally, with the surge in popularity of community solar in Maine, local regulators have warned that the potential for a scam is higher now than ever before.⁶ While community solar can be a worthwhile endeavor, Local news teams have reported on the downsides of some community solar projects, including long wait times after payment and a lack of trustworthiness among providers.⁷ The bottom line is that you should only ever work with a vetted, reputable solar installer with a history of success and good customer service.

Wrap Up: Is Solar Worth it in Maine?

In general, going solar in Maine is an excellent option that could save you tens of thousands of dollars in energy rates after your panels pay for themselves. However, solar panels aren’t right for everyone, and you need to analyze your property to confirm your solar viability before committing. Some things you’ll want to consider include the size of the system you’ll need, your solar panel payback period, shading on your roof, your home’s energy efficiency, the direction your roof faces, the net metering program available from your utility provider and more. Given how complicated the process can be, we recommend reaching out to a reputable solar installer to help you decide if solar is right for your home.
