Off-grid Solar Energy

Is your property connected to the power grid? If not, a standalone off-grid solar is an excellent option for reliable, affordable, and clean energy in Maine.

Benefits of off-grid solar

  • No electric bills ever
  • Greater energy independence
  • Cheaper than being connected to the grid (depending on distance)

Are solar panels a good alternative to a gas generator?

In Maine, there are many rural properties that aren’t connected to the power grid. Solar panels are a great energy solution for houses that aren’t on the utility grid. Off-grid solar is a cleaner, quieter, and simpler alternative to using a generator. At Sundog Solar, we use the most reliable technology on the market to harvest the free power falling on your property to power your home. We serve Portland, Rockland, Augusta, Bangor, Ellsworth, Bar Harbor, Eastport, and beyond.

How do off-grid solar systems work?

Sundog installs roof, ground, and pole-mounted solar panel systems. The solar electricity is used to power your home, and the excess energy is stored in your battery bank. This energy is available at night, on cloudy days, or whenever you need the power, reducing or eliminating the use of a generator.

What does the solar inverter do?

The solar inverter converts power from DC power from the batteries to AC electrical current that your household appliances and electronics can use. Inverters are necessary if you want to use AC-powered appliances and devices, such as washing machines, lights, computers, televisions.

For off-grid solar systems, some people choose to use DC-powered appliances without an inverter and the appliances directly draw DC-power from the batteries. Sundog Solar installs quality Schneider Electric Conext, Outback, and other solar inverters.

What are the disadvantages of off-grid solar?

Your solar system will contain solar panels and a bank of lead-acid or Lithium batteries. Having an off-grid system requires homeowners to be more aware of their energy use and the amount of power stored in the batteries. Although the inverter and solar panels for your home require little if any maintenance, the batteries will need to be replaced periodically.

Do your solar systems include warranties?

Yes, Sundog Solar provides excellent warranties on all the solar systems we install. Because we customize each system for the installation, the warranties vary depending on the solar equipment.

For example, we install Solaria solar panels with a 25-year manufacturer’s warranty and power performance guarantee. Many other solar panels have a 12-year manufacturer’s warranty and a 25-year power performance guarantee ensuring a certain efficiency level over time. Outback and Schneider off-grid inverters come with a 5-year warranty, and the batteries typically have a 7-year prorated warranty.
