Solar Energy Systems

solar farm thomaston MaineMany Maine businesses want to lower their operating expenses. A commercial solar energy system is a great way to cut energy bills and create greater energy independence. With high electricity rates and dependence on fossil fuels, taking advantage of solar energy is practical.

Solar PV is a proven technology that uses reliable equipment to offset some, most, or all of your business’s electricity use. Sundog Solar has installed solar systems on farms, office buildings, schools, landfills, retail stores, and a car dealership.


Take Advantage of Solar Tax Credits and Write-offs

Businesses can take advantage of a 26% federal tax credit. This is a dollar-for-dollar tax credit off federal taxes owed, which is more lucrative than a tax write-off. Solar businesses can also take advantage of accelerated depreciation for 85% of the system cost over a six-year period. These solar energy tax incentives can dramatically lower the total of the solar system.


Maine Has Great Solar Energy Potential

solar farm MaineMaine receives a yearly average of 4 hours of sun each day. When you consider that Germany averages 3.5 hours of sunlight each day and is a world leader in solar integration, Maine is perfect for solar energy. Even during the winter months, solar panels can produce a lot of energy.

Featured Commercial Solar Energy Projects


MDI High School in Bar Harbor, Maine

Project Size: 435 kW

Commissioned in: 2019

As the largest solar system on a high school in Maine, this installation generates 100% of the power consumed by the school. The project consists of 1,450 solar panels and will save the school an estimated $1.3 million over 25 years. Superintendent of Schools Marc Gousse likes the benefits of the solar system on the bottom line.

“It’s going to mean an impact over the next 20 years, of a savings of over $1 million – which, when we talk about resources, those are resources that we’re able to look at devoting to other programs and teaching and learning in our communities.” 

The solar system was made possible with a collaboration between multiple stakeholders. “I am incredibly proud of the collective efforts that have led us to this momentous occasion.,” says Matt Haney, MDI High School principal.


Mid-Coast School of Technology – Rockland, Maine

Project Size: 312.5 kW

Commissioned in: 2020

As one of 27 vocational schools in Maine, the MCST helps prepare students for economic and personal success. The newly constructed 91,000 square foot facility has wide windows and geothermal heating and cooling equipment. Efficiency Maine is also providing significant rebates due to the energy-efficiency features of the building. Sundog Solar installed a 1,000-panel solar array on the roof of the school. 

“Every high school in Maine is looking for ways to reduce their operating costs,” says Sherry Moody, business manager for the Midcoast School of Technology. “Having a green building with solar panels is a great way to save money for things that truly benefit students.” 

“Schools are a great match for solar energy systems,” explains Chuck Piper, co-owner of Sundog Solar. “They draw more power during the day, which corresponds with the available sunlight. It also helps promote awareness of the benefits of solar energy within the school and surrounding communities. We also installed a large solar energy system on MDI High School in Bar Harbor and it was widely celebrated within the community.”


Tremont Landfill – Tremont, Maine

Project Size: 153 kW

Commissioned in: 2019

Installed to save taxpayer dollars and to help the environment, the Town of Tremont entered a Power Purchase Agreement with Sundog Solar. The town now purchases electricity at a discounted rate compared to utility power, saving hundreds of thousands of dollars over the life of the system. When constructed, this solar farm was the largest array on Mount Desert Island and the first solar landfill in former Emera Maine territory.

This system is located on a capped landfill that has been closed since 1996. The property provided little value to the community, thus the solar system is a win-win for the town and the environment. This project was installed as part of a larger vision to make Mount Desert Island energy independent by 2030 and to make it an epicenter of citizen engagement, sustainability, and economic vitality. 

“This solar project is a win-win for the community of Tremont,” said Town Manager Christopher Saunders in the release. “It lowers the town’s long-term energy costs and is good for the environment.”


Waldoboro Transfer Station – Waldoboro, Maine

Project Size: 110 kW

Commissioned in: 2017

community solar farmCapped landfills have few development options and provide little ongoing value to local residents, yet there are more than 400 of them in Maine. Located on a closed landfill, this solar array is an excellent opportunity for the town to save money and efficiently use space. 

The solar PV array was installed with a Power Purchase Agreement and has resulted in instant savings. Waldoboro Transfer Station Solar system monitoring allows residents, town officials, and other stakeholders to monitor the system via an internet portal. 

Sundog Solar has been working closely with the Department of Environmental Protection to develop solar arrays on closed landfills and obtain the required permits for siting a solar system on a landfill site. The solar arrays required a staggered layout to avoid test pits and methane gas vents that must remain unobstructed. The solar panels do not disturb the protective clay cap, thus making them the perfect location for a solar energy system. 

“We’ve been very satisfied with the production from the solar system,” said Julie Keizer, town manager for the Town of Waldoboro. “The solar system has been producing clean energy for over a year and it is reducing the town’s energy expenses.”


Oakland Landfill – Oakland, Maine

Project Size: 497 kW

Commissioned in: 2020

The Town of Oakland is producing enough solar energy to offset all its power, including sewer pumps, the fire station, police station, town office, library, and town garages. The array was installed on a capped landfill under a power purchase agreement and is expected to save the town $1 million in energy costs over 20 years. 

“Not only is the land the perfect spot for a solar array, but it is also ideally located next to 3- phase power and just down the street from a CMP substation,” says Chuck Piper. “It will allow for substantial future growth.”


Thomaston Wastewater Treatment Facility – Thomaston, Maine

Project Size: 503 kW

Commissioned in: 2021 (anticipated)

thomaston maine solar energy systemThe Town of Thomaston, Maine, installed a solar system to provide power to the treatment facility, fire station, town office, public works, and street lights. The system will produce an estimated 90% of the town’s power. The town owns the solar system outright and was made possible with a low-interest loan through the Maine Municipal Bond Bank. The solar energy installation features bi-facial solar panels.

“We can install the solar energy system with no increase in taxes or resident fees,” said John Fancy, superintendent of Thomaston Pollution Control Department. “Instead of paying a higher electricity bill, much of the electricity savings will go towards paying off the loan.” 

That means the project will be cash flow positive right away. Wastewater treatment plants are energy-intensive operations because they require moving millions of gallons of water during the treatment process. The Thomaston plant is a modern lagoon-type facility constructed in the 1990s. The town is also working on other clean energy initiatives, such as installing an electric vehicle charging station and replacing inefficient equipment.
