Off-Grid Solar PV Systems

Off-grid solar photovoltaic (PV) systems utilize solar batteries to store electricity when there is sufficient solar radiation to satisfy the electrical demands in the home. The off-grid 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 in Maine. These off-grid solar energy storage systems are typically utilized in places where access to the grid is impractical or expensive, like on the islands of Maine. These systems are commonly used for seasonal cabins and residential homes located away from existing electrical infrastructure.

Generator Backup Power

Most off-grid solar PV systems in Maine are supplemented by a backup generator that provides consistent power even when there is limited access to the sun. The demand for a whole-home generator depends upon the storage capacity of the battery bank, the electricity demand, and the ability for the solar PV modules to recharge the battery bank. We provide backup generator installation services for our off-grid solar clients in Maine.

We work to provide a balance between cost and comfort – namely the cost of backup batteries and propane for running a whole-house generator and the comfort of having a backup power system that provides continuous electricity while minimizing the hum of a generator.

Off-Grid System Design

Due to the need for electrical reliability and energy independence, the design process for off-grid solar PV systems in Maine is very detailed and requires an accurate assessment of the electrical use at the site.

As an off-grid solar company, we provide the design and installation of certain off-grid solar PV systems and backup generators. Typically, our off-grid clientele are those who are looking for whole-house systems or larger camp systems in Maine. Due to the economics of designing and installing small off-grid systems, it is often difficult for us to attend to the design and installation of systems of one or two solar PV modules. If you are looking for guidance on an off-grid system to satisfy small electrical loads, we are willing to connect you with good resources for doing so successfully.

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.
