Canadian Solar

As one of the largest solar panel manufacturers, solar contractors on several continents widely use Canadian Solar panels. These solar panels fall in the standard efficiency category, with most panels being 16 to 17 percent efficient and having a 10-year warranty for defects.

Hanwha Q Cells

Combining high quality and low prices, Q Cells are a popular product among Sundog Solar customers. Most of these solar panels are between 16 and 18 percent efficient and have a 12-year warranty for defects, which is two years longer than the industry standard.


With a reputation for producing high-quality electronics, their solar panels follow suit. These panels are between 18 and 21.7 percent efficient and also have a 12-year warranty for defects.


Manufactured in North America, Silfab solar panels have quickly created a name for themselves. With solar panel efficiency up to 19 percent and a 12-year warranty for defects, Silfab sets itself apart from more standard solar panels.


Manufactured in the United States and South Korea, Solaria panels are gaining popularity with Sundog customers. With less wasted space a high shade tolerance, these panels can produce 20 percent more energy. Due to their all-black appearance, solar system owners appreciate their sleek appearance.

What is an inverter, and do I need one?

Inverters used in solar electric systems convert DC power to AC power. Inverters are necessary if you want to use AC powered appliances and devices, such as washing machines, lights, computers, televisions, and solar contractors install them reinstalled in all grid-tied solar systems. In the case of off-grid solar, some people choose to use DC powered appliances. Thus the inverter isn’t needed because the devices directly draw DC power from the battery bank. In this case, the source of energy is always a battery bank. Inverters come in a variety of sizes, some as small as 12 Volt/100 Watt inverters up to 48 Volt/6000 Watt inverters.

Which solar inverter is right for me?

We size your solar inverter by determining the number of appliances and devices you want to run simultaneously. For example, if you run your washer and your well-pump and television simultaneously, you might need a 4,000-watt inverter. If your use of appliances is more sporadic, you could utilize a smaller inverter. Sundog Solar offers several quality brand inverters, and our solar energy experts can help you determine which inverter is best for your energy needs.

What is a solar charge controller?

Almost every PV system that uses batteries requires a charge controller. They manage battery charging within the batteries’ limited charging capacities while protecting the batteries from overcharge and over-discharge.  Batteries in PV systems in Maine experience a range of operating conditions and must be regulated to maximize their performance and lifespan.

Do I need batteries for my solar system?

This depends if you want emergency power during grid outages or if you are connected to the power grid. Batteries are a crucial component in off-grid PV and grid-tied solar systems with battery backup, serving as the energy storage device. The Sundog Solar team can help you match battery power capabilities to your energy needs.

Sundog Solar offers batteries from several reputable companies, including Rolls Surrette, LG Chem, and Pika Energy. We provide several different types of batteries, including lithium-ion and deep-cycle lead-acid batteries (including Absorbent Glass Mat or AGM batteries), for a variety of applications. We use batteries with comprehensive warranties to protect your solar energy investment. Sundog Solar can also inform you about battery maintenance, crucial in preserving your batteries’ lifespan and optimal functioning.
