A large majority of grid-tied PV systems are battery-less systems that utilize a net metering arrangement with the electric utilities to receive compensation for additional electricity that they deliver to the grid.

Insource Renewables provides full-service design and installation of grid-tied PV systems for residential and commercial clients in Maine.


Like a refrigerator or air conditioner, heat pumps use refrigerant, a compressor, and various valves to move heat from one area to another. Mini-split heat pumps (MSHPs) move heat into a home or business during the heating season and provide cooling or dehumidification in the summer. The electricity required by these appliances to move heat costs significantly less than burning oil or propane.

Insource Renewables installs and services ductless and ducted mini-split heat pumps for residential and commercial applications.


Off-grid PV systems utilize batteries to store electricity when there is sufficient solar radiation to satisfy the electrical demands in the home. The systems, also known as “standalone” systems, range from small systems for running emergency signs and lighting to systems that satisfy the full demands of a home or business. These systems are typically utilized in places where access to the grid is impractical or expensive. These systems are commonly used for seasonal cabins and homes located away from existing electrical infrastructure.

We provide the design and installation of off-grid PV systems and generators. Typically, our off-grid clientele are those who are looking for whole-house systems or larger camp systems.


Solar water heating technologies absorb the sun’s radiation for domestic water heating or commercial water heating. Well-designed and properly installed solar heating systems last for decades and provide their owners with significant cost savings.

Solar water heating systems are cost effective solutions for homes and businesses with moderate to high water heating loads. In residential applications, these systems are designed to offset 60-70% of the energy required for annual water heating. With an auxiliary source of heat, such as oil, propane, or electricity, owners always have the comfort of hot water without the typical energy costs.


Solar pool heating (SPH) systems are the most popular solar heating system in the United States. SPH systems are very simple and provide a viable alternative to heating a swimming pool with gas, oil, or electricity. They have virtually no operating costs, which results in an almost immediate payback for pools that would otherwise be heated with fossil fuels or electricity.

A solar pool heating system is the most cost-effective heating solution for pool owners seeking greater comfort or looking to extend the swimming season. These systems use simple polypropylene collectors that can maintain temperatures of 85-90 degrees Fahrenheit through the typical swimming season.

Insource Renewables designs and installs solar pool heating systems for residential and commercial applications.

Our owner, Vaughan Woodruff, authored two articles for Home Power magazine related to swimming pool energy efficiency and solar pool heating. These articles provide insight into effective solutions for getting the most enjoyment out of your pool:


Electric vehicle (EV) charging stations provide electric car owners with convenience and faster recharging than is available with a standard 120V outlet. These units provide are especially useful to EV owners who use their car as a daily driver or to businesses that see benefit in providing EV charging to the public or to their customers.

We have a highly qualified staff of electricians ready to serve your EV charging needs. When combined with solar, this solution offers Mainers the option to power their transportation needs with the sun.

  • Vaughan has professionally bridged the gap between being a contractor and being an advocate for Maine homeowners in their mission to save energy. He is not a ‘one size fits all’ in terms of efficiency and many times he has recommended our services over his own when looking at the types of challenges homeowners face when decreasing their carbon footprint.

  • Working with the Insource Renewables team was for me not only a satisfying experience but also encouraging about the renewable energy industry itself. These people were well-informed and articulate in their advice and planning on my project.

    They brought the fruits of both long experience with solar design and deep conviction about the importance of renewable energy in today’s world. In follow-up, they have been generous and good-natured in answering questions.

  • We contracted Insource Renewables to install a solar heater for our swimming pool and a cluster of home energy improvements. We were very pleased with the expertise, integrity, and work ethic of Vaughan Woodruff and his fine team.

    We were consistently informed of and/or consulted on scheduled activities and events throughout. At every juncture, Vaughan and his team were obviously guided by the principle of doing what is right for the customer.

    We have recommended to our friends and continue to unreservedly recommend Insource Renewables for any energy-related projects.

  • We are very happy with our new solar panels from Insource Renewables. It’s great that, now, our house is a power generation factory! Vaughan and the rest of the team are excellent, knowledgeable, friendly, proactive. Within 2 days of the start of the project, our meter was running backwards! It’s satisfying to make a small but real change in the severe climate issues that our planet is facing. I’m also really thankful that Vaughan connected us with the Greater Bangor Solarize program, which saved us over $2,000 on our installation! Vaughan provided us with many different options and answered so many questions that we had, until we found the solar project that was right for our family.

  • We discovered Insource Renewables (and Backyard Buildings in Unity) this Spring and were immediately taken with the concept of the “solar shed.” We knew we needed to build or buy a shed for some extra outdoor storage, and I’d always wanted to go solar at our house, so this made perfect sense!

    Matt, Vaughan, and the whole team at Insource were excellent to work with, answered all our questions, and made sure everything came together on this project. We are excited to be building out the inside of our shed while knowing we are making power every day just by having this system in our back yard.

    Great job all!

  • When our heat pump had electrical issues, there are a couple of ways that this event could have gone. Insource could have blamed the manufacturer, basically come back and continued to tweak the unit, or – worse yet – not been terribly responsive overall. I can’t tell you how good and stress free it has felt to know that you guys have put the customer first and have done your absolute best in the matter.
    We are very grateful.
