A Canadian's Guide to Off-Grid Living with Solar in 2024

Solar power can easily get confusing. So, as North America's #1 off-grid living solutions provider, we felt it would be helpful to answer the most common questions in very simple, non-technical, easy to understand language.

The internet is filled with videos, blogs, pictures, recommendations and other information that’s often contrary or downright ridiculous. Online calculators are also common, meant to help you choose the right ‘package’ for you.

But in most cases these calculators don’t take into account that every application is different, and the actual requirements are as unique as the individual – so we work with customers & provide recommendations not just for solar energy products but their entire off-grid living experience. That’s because making some minor changes to your lifestyle or choosing the right appliances can have a significant impact to the size (and ultimately the cost) of your solar power system.

Purchasing your solar power system for full-time or part-time use is no small investment for most Canadians - informing yourself before purchasing is very important. Luckily, you've come to the right place, The Cabin Depot has been in the business for over 10 years and helped over 20,000 people go off-grid with solar. 

The first step is to understand what off-grid living means, and the differences between off- grid and grid-tied solar power systems.

What does off-grid living mean?

Living off-grid essentially involves being self-sufficient and independent from public utilities, by generating all of your own energy on-site. This is commonly achieved through the use of solar energy. 

Living off-grid is a lifestyle choice that involves generating and using energy without relying on the traditional power grid. This lifestyle is often attractive to those who value self-sufficiency and independence.

However, despite the potential benefits of living off-grid, many homeowners may feel hesitant to pursue this lifestyle because of concerns about legality. It is not uncommon for people to assume that living off-grid means breaking the law, but this is not necessarily the case.

Off-Grid Systems vs. Grid Tied Systems

Off-Grid Systems

  • Off-grid systems are autonomous, meaning they are designed to be completely independent of the local power grid. These systems are used for off-grid homes, cottages, cabins, RV’s, boats, and other applications where access to grid power isn’t possible or impractical. These are the systems that The Cabin Depot Ltd.™ specializes in. 

Grid-Tied (On-Grid) Systems

On-grid or grid-tied power system example schematic

  • Grid-tied systems use solar panels to offset energy consumption in your home. These systems require the approval of the power utility, site inspections, and certified electrical contractors to The Cabin Depot Ltd.™ does not offer these systems today, but we can recommend companies in your area who would be happy to help.

So, if your application is for off-grid use - terrific! Then read on…

Off-Grid Solar Power System Components

All off-grid solar power systems are made up of four key components.

The Components of An off-grid solar system diagram

  • Solar panels = converts sunlight to DC (Direct Current)
  • Batteries = stores the DC energy that is produced by the solar
  • Charge controller = ensures proper charging of the battery
  • Inverter = converts DC energy to household 120/240vAC (Alternating Current)

People get very excited over solar panels, often rushing out to buy them first before properly sizing their system. Solar panels purchased because they are ‘on sale’ may seem like a bargain at the time, but if they aren’t the right type or size, they can actually cost you more money when finally installed. The reality is that your batteries are the most important component of an off-grid power system!

The size and type of these components will depend primarily on the electrical loads that you want to service. This can be confusing as the jargon can become more technical, but here’s the bottom line

To significantly reduce the size (and cost) of a solar power system, you will want to avoid (when possible) powering any appliances or devices used for heating or cooling air, water, and food electrically. 

How much solar power do I need for an off-grid cabin?

The size of your solar system is entirely dependent on your electrical load. In other words, to find out what size off grid solar system you need, you need to find out your estimated daily watt/hour consumption. This can be done simply by multiplying the amount of watts that an appliance is rated for (this can be found on the back/bottom of the devices, or look for a tag with electrical info.) and multiply that number by the estimated hours of use in a day. Repeat that process for each appliance that you know you’ll be using with your solar system, tally up the watt hours for each appliance and viola, you have your daily watt hour consumption. 

There are useful tools online for calculating your watt hour consumption, such as this calculator that provides the most common types of appliances with an estimated power rating for each - just in case you don’t feel like pulling out all the tags of your appliances. In most cases, and for better accuracy, this info can be found online by searching “Appliance name here watt rating”.

It is also important to note that the requirements listed on the appliance tag generally reflects the maximum energy requirements of that appliance. Typically, you’re not using that appliance at maximum wattage for the entire time you’re using it, so you’re overcompensating to give your solar system better performance on cloudy days where energy production is low.

Curious on exactly how much power your appliance is drawing? Check out the Kill-A-Watt Cumulative Kilowatt-Hour Monitor.

What are ‘Days Of Autonomy’?

This is referring to the consecutive days during which power generation becomes impractical due to cloudy or rainy weather conditions, but you’re still using energy. On an average day, you can rely on approximately 5 hours of sunlight for power generation, while your energy consumption remains constant throughout the entire 24-hour period. A system with two days of autonomy would possess batteries of sufficient capacity to sustain continuous energy supply for a complete two-day duration without requiring recharging.

Typically, a standard range of three to five days of autonomy is widely acknowledged and accepted.

Electrical Loads

Electrical loads are all the things that you will have “plugged in” to power electrically.

Electrical plugs connecting with sparks

Examples would be:

  • Small Loads: LED lights, LED television, satellite receiver, radio, cell phone charger, small diaphragm water
  • Large Loads: Keurig coffee machine, microwave, hair dryer, hot plate, air conditioner, AC powered refrigerator, deep well pumps.

When it comes to solar power equipment selection, you must consider your electrical loads first. Your total investment will be much lower if the system is used to power small loads because you won’t require as much energy. You can still power large loads using solar, but your system components will need to be larger in order to store the additional energy required.

There is a direct correlation between your overall loads and the system cost.

You will need to balance convenience with practicality. For example, it would be nice to have an air conditioner at the cabin, or to run the AC in your RV, but the cost of a solar power system to run one will add many thousands of dollars to a system cost. So, thinking specifically of ways to reduce cost, here are some examples:

  • Heating: use wood as your primary heat source, or a direct-vent propane heater as a secondary option. Heat water using an on-demand propane tankless water heater. Cook food on a wood stove, or more commonly, an off-grid propane.

 Heating options, woodstove on the left, boy in chair beside warm propane direct vent heater on the right

  • Cooling: install a propane or solar/DC refrigerator, or select a smaller portable AC/DC powered fridge/freezer. Utilize high-efficiency / low power cooling fans or ceiling.

Unique and Sunstar Solar Appliacnes

Refrigeration is usually the largest consumer of power in an off-grid application. A typical household refrigerator uses 120vAC to operate. They usually have auto-defrost, ice makers, and other accessories that ramp up energy consumption. Even a basic 120vAC refrigerator will be rated for around 250 watts operating, with a surge (when the compressor starts) approaching 1000 watts.

Furthermore, in an off-grid application, you would be using DC power from your batteries and converting that to AC power via an inverter to run your refrigerator. Inverters suffer from conversion loss (when taking battery DC power and converting to household AC power), so you can count on ‘wasting’ anywhere from 5% to 15% of your energy through this conversion. As such, customers wanting to run an AC refrigerator will need to invest in a larger solar power system to operate it, which typically costs more than replacing the refrigerator with a solar/DC model designed for off-grid use in the first place.

Unique Solar/DC Refrigerators


A solar/DC refrigerator is designed with energy efficiency in mind. They have more insulation, a specially designed DC compressor, and connect directly to your battery bank. Since there’s no inverter required, there’s no conversion loss to worry about. There are many models of solar/DC refrigerator, but most are rated for around 55 - 65 watts when operating. This means you’re able to get away with using a much smaller solar power system to operate one.

Unique Off-Grid Appliances have some stylish classic retro colour options. Sunstar refrigerators, however, are the most efficient off-grid refrigerators and freezers we've seen, by far. Sunstar Solar Appliances use dedicated DC compressors for each fridge/freezer cabinet, 4" thick insulation and are 100% made in America.

Estimated Solar Power System Cost

Just like buying a car, your budget and lifestyle will determine how much money you will eventually spend on a solar power system. And just like buying a car, there are many options and accessories available. If you want more bells & whistles, or more convenience, you’ll spend more money. It’s that simple.

Below are some examples which demonstrate the typical differences in cost:

Small system:

  • Uses 12vDC battery power only (no inverter required).
  • All electrical loads connect directly to the battery
  • Can operate 12v LED lights, 12v water pump, 12v ceiling fans, 12v refrigerators,
  • Typically used for hunting camps, weekend-use cabins, RVs, boats, yurts, vans.
  • A small inverter could be added to run a TV or radio for a few hours at a time,
  • Approximate cost: $350-$2000 for a complete setup.

Medium system:

  • May use a 12vDC (or 24vDC battery bank with the use of a step-down converter) to power the same 12vDC devices listed in the ‘small system’ above, but adding a small inverter to supply 120vAC power for small AC loads such as radios, TV’s, DVD players, cell phone chargers, CPAP machines, etc.
  • Typically used in seasonal cottages, camps, or cabins where you may spend weeks at.
  • Can operate solar/DC refrigerators and other appliances designed for off-grid.
  • Will typically use a gas or propane generator to run larger load items as needed i.e. coffee maker, hair dryer, air conditioner, This is usually more cost-efficient vs increasing your solar system size to run these items for short periods of time. If you don’t want to use a generator, you can expect to add ~$1000+ to the system cost.
  • Approximate cost: $1000-$3500 for a complete setup.

Large system:

  • Uses 120vAC and/or 240vAC
  • Uses 12vDC battery power only (no inverter required)
  • Typically operates household electrical loads year-round
  • Some exceptions, such as electric baseboard heat, electric ranges, or electric clothes washers are usually replaced with propane models.
  • Northern climate off-grid houses will always have a backup gas or propane generator, used occasionally in the winter months to charge the battery bank after consecutive days of poor weather
  • Approximate cost: $7500 (with careful energy management) to $25,000+ for a complete setup. 

It’s important at this point to remind you again that every solar power system is as unique as the individual using it. Buying a “kit” that is too small or not expandable will leave you without power when you need it the most and limit your ability to expand. Buying a kit that’s too large for your application is just a waste of money. So, remember - BIGGER IS NOT BETTER!

Our primary goal is to ensure your off-grid solar power system is suitable for your specific application and lifestyle, so we always recommend building it for future expansion. That way you can start off with what you ‘think’ may work and add to it in the future without having to replace all of your key components or wiring.

Portable Solar

If you're someone who might appreciate the utility of taking power on-the-go, or maybe you are in the middle of a build project and don't want to run half a mile of extension cords everywhere, a portable solar solar system may be worth looking into. 

EcoFlow DELTA mini Portable Power Station Kit

A portable solar kit is a more convenient and flexible option for those who need power on the go or in temporary locations, such as camping, RV trips, or emergency situations. They are designed to be lightweight and compact, making them easy to transport and set up wherever needed.

Stationary Systems

On the other hand, a stationary solar kit is a more permanent installation that is designed to provide reliable and consistent power to a home or building. They typically have a larger capacity and are connected to the grid or a battery system, allowing for long-term energy storage and usage. The choice between a portable or stationary solar kit ultimately depends on the user's specific needs and circumstances.

Is Off Grid Solar Illegal in Canada?

No, off-grid solar is not illegal in Canada. In fact, Canada is one of the leading countries in the world when it comes to renewable energy, and many homeowners across the country have installed solar panels to generate their own electricity and live off-grid.

In most provinces, there are no specific laws that prohibit living off-grid or generating your own energy. While there may be regulations governing the installation of renewable energy systems such as solar panels or wind turbines, these are generally put in place to ensure the safety of the public and the environment. 

It is important to note that the regulations and requirements for renewable energy systems may vary depending on the province or territory where you live. For example, in some areas, you may be required to obtain permits or follow specific installation guidelines when installing solar panels or other renewable energy systems. It is important to research the regulations and requirements in your specific area before embarking on an off-grid lifestyle.

Paul & Doug, 2 stroke gas for the chainsaw is much cheaper then running large gauge wire, or consider building a small outbuilding with batteries and inverter and running your DC power (AC from panels to batteries to inverter then converts to DC) to your cabin. Both solutions beat the heck out of the cost from running large gauge wire long distances as well as power loss from running DC from a distance.

I have a hunt camp west of hornpyne ont .We are running a propane fridge with issues now.
I bought a new 12 volt fridge. not researching the solar side of this project. so new fridge $2,100. first quote on a solar system $5,000 WHAT!!! Did not plan for this cost. all I want to run is a few led lights and this fridge. Most trips are 5 days.the other thing is that I would like to take the panels down when I leave the camp. also can the batteries take the cold weather through the winter? Please Quote a simple system

400 feet is much too far a cable run, even for 48 volts. Even using a thicker (and more expensive) gauge of wire not be enough to overcome the voltage drop at that distance. I would lean towards upgrading the panel array and possibly the batteries. If it hasn’t been done yet, upgrade the charge controller to a “MPPT” type to make the most of the limited sunshine on the roof. The MPPT usually allow you to run higher voltages on the input and a choice of lower voltages for the output to the batteries. You may be able to eke out a couple more amp/hrs per day from the roof it you come down at 48V instead of 12 Volts.

Doug Seeglitz - March 25, 2023

Currently have a small 12v system with 1000watt inverter, running led lights, phone booster, a few small phone chargers, stereo, small vacuum and a 12v water pump for shower. Use propane for on demand shower water heater, stove and fridge. Have 2 solar panels at a little over 500 wh to charge 280 ah gel 12v battery. Panels only in full sun half the day and thinking of going 48v with moving panels over 400 feet where they can get full sun. Any suggestions?
