Grid-tied solar photovoltaics (PV)

Grid-tied solar electric systems utilize PV panel modules and solar inverters to deliver clean electricity.

Grid-tied solar PV systems avoid the need for solar batteries, which create additional expense and maintenance. The tradeoff with a grid-tied solar energy system is that there is no stored excess energy in the home – at night, on a cloudy day, or during times of high use, electricity is purchased from the grid.

It is possible to install a solar energy system that offsets all of your electricity consumption through the net metering arrangement described below. Since these solar systems are modular, a smaller system can be installed based upon your budget or site limitations.

Net Metering

Grid-tied solar PV systems require customers to enter into a relationship with their electrical utility, such as CMP. Through the interconnection process, the utility reviews the type of equipment and size of the solar energy system to verify that the transmission grid can handle the output of the system when it is exporting power from the site. For most residential systems, no changes to the grid are required to interconnect the system.

These systems first provide electricity to the electrical loads in the home or business. If the system generates more electricity than is being consumed, the excess is delivered to the grid. The utility measures the amount of electricity that the PV system delivers to the grid and provides a credit to the owner’s utility bill. In Maine, we have 12 months to use this excess electricity. Owners are not compensated for any surplus electricity that is generated during the 12-month cycle.

Grid-tied solar PV with storage

Solar battery storage can be incorporated with a grid-tied solar PV system to provide electricity when there is a power outage or to best utilize time-of-use / peak demand electricity rates. New electrical storage options are quickly emerging in the market, and we actively evaluate these new technologies to determine their applicability to our customer’s specific energy needs.

We work with traditional lead acid battery storage, which is typically configured for 12V, 24V, or 48V, as well as emerging high voltage battery storage.

We offer system monitoring standard with every solar PV system we sell. If you have an Internet connection, our systems can provide remote energy monitoring that shows how much energy is being produced by the system and will send alerts to us if there are any issues that arise with the system. This provides accountability and quick response to any service issues that might arise.

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.
