The Best Off Grid Solar System for Home and Camping

The off-grid solar system is perfect for anyone that wants to harness their energy completely from the sun. A good off-grid solar system will have all the equipment you need to generate, supply, and store solar energy. They will also operate without an external power source and can therefore operate all by themselves.

When the sun isn’t available, you will need to use a battery to keep the off-grid system running. Batteries can be costly so off-grid solar systems can sometimes be more expensive than a simple generator or other solar power systems.

When looking for an off-grid solar system, some will come with the full kit while others you may need to buy a few things separately. No matter what, you will need the solar panels, the solar charge controller, the solar inverters, the solar battery, the mounting and racking system, quality wiring, and junction boxes.

The best part about off-grid solar power is the way it can be combined with more panels or separated depending on what you want to use it for. This allows you to be extremely flexible and have a wide variety of uses. Off-grid solar systems need to be highly durable and be able to work in direct sunlight as well as in cloudy areas.

Most people use off-grid solar for electricity in small cabins, powering appliances in an RV, powering small-energy efficient homes, and providing charge to phones or tablets. The size and energy of your off-grid solar system will determine how much charge is available to you.

We will discuss the best sizes of off-grid solar systems and the typical pricing for them in the buyer’s guide section at the end of this article.

When deciding on a proper size though, there are a few things you should keep in mind. The peak load and daily average energy consumption are measured in kWh and are very important. The peak load is the maximum power drawn from appliances. Average continuous load is also important and measured in kW.

Solar exposure can be determined by location, climate, orientation, and shading. Off-grid systems can also be used for backup power options such as in poor weather or electrical shutdowns.

FAQ Section 

How Can You Size an Off-Grid Solar System?

Choosing the correct size for your solar system can be crucial for ensuring you have all the power that you need, especially in emergency scenarios. An off-grid system sizing calculator can help you complete a load evaluation to successfully determine how much power you will need.

There are a few steps to take, and they are pretty easy to perform.

Calculate Your Electricity Needs

Make a list of all the appliances you will need and how many hours, on average, you will be using them for. You can then figure out the power consumption of each appliance and then add them all together to see how much power consumption you need daily.

Make sure to convert everything into kWh as this is how solar panels measure power output.

Figure Out the Instantaneous Load Requirements 

This refers to how many appliances you will be running at the same time. This will be your instantaneous wattage requirement. This number is crucial when referring to the size of the inverter you will need.

The inverter will run on AC loads which is the type of electricity that it converts to run effectively.

Choose a Battery Storage Capacity 

This will determine if you have the extra backup capacity or if you only want enough power to run your appliances from day to day. Most people who choose to have a solar battery backup will get enough storage to cover at least 2–3 days of usage at the time of the year when you use it the most.

Use the Steps to Design a System 

Now that you have determined the appliances that need power, you will be able to determine the type of kit you need. You will also need to take into account the type of solar panels, the inverter, and the battery storage.

How Much Does an Off-Grid Solar System Cost?

The price for an off-grid solar system varies widely depending on the kind you get and how much power you want it to be able to use. Small systems that are just for a phone or small appliance can be as little as $50.

However, if you are looking to power an entire home, you will need to have quite a bit of money saved up. Small homes or cabins may need a system that will cost between $12,000 and $20,000.

Large homes can be between $20,000 and $50,000. A mid-sized home will usually fall somewhere around $35,000. An RV or S system for camping is usually around $2,000 if you plan to power all the appliances in your RV. It could be slightly more if you plan to get a system that can power an air conditioning unit.

These prices include just the equipment. If you are not comfortable installing it by yourself, you will also need to factor in the cost of labor from a solar installation company. If you are doing it yourself, you may also need to buy tools and drills.

Some counties and states also make you pay a permit fee.

What Are the Disadvantages/Advantages of Off-Grid Solar Systems?

There are several advantages to off-grid solar systems that regular electricity just does not provide. Every year, hundreds of Americans choose to switch to off-grid electricity because of the freedom and environmental impact that it provides.

Encourages a Better Lifestyle

With a busy lifestyle between work and family, it is easy to become disconnected from the energy and electricity that we use to power our homes. We often will just pay the bills without thinking concretely if there is a way we can do better.

Having a solar system will naturally make you more aware of how much power you are consuming and where it is coming from. It will also get you more in touch with your consumer lifestyle and all the disposable things you may use in your life.

The off-grid solar system will also make you reevaluate your lifestyle and make you more conscious of the world around you.

Sometimes It Is the Only Option 

If you are looking to live more remotely or want to be in a quiet area, sometimes, the power supply to these areas is limited. To have electricity from a major company, you will need to be in the coverage area of the utility company, which is not always possible.

Being out of a coverage area means producing your own electricity. Sometimes, solar is not the only option though. Backup generators are always available but can be expensive if you plan to use them all the time or for multiple appliances. Hydropower and wind power are also viable options for some environments.

Solar power, though, is often the most practical and can be used anywhere.

More Freedom 

One of the reasons people choose to live off solar power is because of the total freedom it gives. It means you don’t have to be dependent on the power company for all your needs. This is especially important if you plan to live in an environment that has frequent power outages or extreme weather where you could lose power often.

Some cities and states also have much worse power supplies than others, so going with a solar power system can ensure that you always have power even when the power company is delayed.

Better for the Environment 

One of the most popular reasons why people are switching to solar panels is because of their eco-friendly quality. Going with natural power will reduce carbon emissions and your carbon footprint.

You also don’t have to worry about contributing to fossil fuels and their harmful effects on the environment.

With advantages come some disadvantages. There are reasons why most people continue to rely on power companies, and the reasons are pretty hard to get around.

Going Off-Grid Is Expensive 

Although you will never have an electric bill again, the upfront costs of switching to off-grid solar power are expensive. You will need to have a sum saved up to get a high-quality system that is strong enough to power all your appliances and other needs.

Systems for RVs or smaller homes might be cheaper but will still need a durable system that you can rely on. Off-grid systems also need a few things that on-grid systems don’t need such as more panels, a high-voltage capacity inverter, and a large amount of solar battery storage.

There is also no grid to fall back on, so you will need a backup generator which can be quite costly. Generators can’t be relied on for too long, so any problems with your system will need to be fixed promptly which can also drain your bank account.

Potentially Illegal Depending on Your Area

Some countries in certain states have made off-grid power illegal. If you are dead set on living off the grid, you might have to move counties. Off-grid power is illegal in many large cities and other busy areas of the country.

Most people who choose off-grid solar systems choose to live in rural areas where these restrictions do not apply. Always check with your county and state before choosing to go off-grid. Fines and legal fees can be very costly if you break the rules.

Time-Consuming to Set Up

Choosing the right system and figuring out how much power you use can be a trial-and-error process. You will probably spend many months getting a correct gauge which can be time-consuming and require patience.

You will also need to spend devoted time to figure out your usage patterns, the amount of power you will need, and how many panels it will take to generate that amount of power. This could also change depending on how your family changes. If you get married or have children, the power usage will change and need to be adjusted accordingly.

You will also need to take time to learn how to fix parts and any faults. Hiring someone or spending days fixing something can mean going without power until the problem is solved. Your power generation may also be unpredictable and will need to be monitored constantly.

Learning how to do this without stress can take some time.

Major Lifestyle Changes 

One of the largest factors you should consider before converting to an off-grid system is how it will affect your life. If you are on a budget, you will probably have to start with a small system that could not power your entire home.

This means you might not have power all the time. During certain seasons when there is more cloud coverage, you could also risk not having enough direct sunlight to give you all the energy you need. This means you are stuck waiting for the sun to come back out, or you will need to buy a generator.

The restrictions will affect how you live and work. This change will also be even harder if you have children because they will need to take some time to get used to it. Conserving energy also means conserving water and air conditioning. You will probably have to take short showers and not flush the toilet every time you use it.

If you live in a hot environment, you need to consider if you could live without air conditioning all the time.

Overall, though, having an off-grid system has many advantages and gives you a healthy relationship with energy and power consumption.
