So you want to go solar…
But can’t decide how many panels to get, right?
We’re going to teach you a simple little formula to calculate that in seconds..
More on that in a sec..
Your biggest worries will be how many solar panels do I need to go off the grid.
In this article, we will answer this question and provide you more insight into off-grid solar systems.
What Is An “Off-Grid Solar Energy System” Anyway?
To live off the grid completely, you’ll need to create your own electricity since you won’t be on the central power line. Well, you can solve these situations with an off-grid solar energy system. This system acts as a power provider that will help keep your entire electrical appliance running.
The larger electric grid supplies power to most homes and business centers all over the nation. But to go with the off-grid solar system, you will need quite a number of solar panels to generate enough energy to power your home. This is the main reason many stick to the city grid.
Also, in a region where there are lengthy cloudy climates, you will have to get a powerful on-site battery to store power from the sun. This way, you create, store, and use energy when you wish.
Going off the grid with solar systems might be expensive from the beginning, but it will save you more money in the long run.
Can I Go Off The Grid With Solar Panels?
Yes, you can. Solar panels can provide you sufficient electricity for off-grid living. However, there are essential things to look out for and steps to take before installing a solar panel. These considerations will help you know how many solar panels you need to go off the grid.
- Evaluate the amount of power you consume
- Check the number of batteries you need
What Amount of Power do You Consume?
What Battery Capacity Do I Need?
How Many 100W Solar Panels Do I Need to Go Off the Grid?
Here comes the answer you have been waiting for. You should base on the information you have gathered above so you can set up an adequate solar system. In other words, once you know the number of batteries and the power you consume, you can determine the number of solar panels needed.
The off-grid solar system should be big enough to store power that will run for the entire day. You should know that the energy stored from the panel is proportional to the intensity and period of sunlight a day.

Important Components Needed for an Off-Grid Solar System
The off-grid solar system consists of many things. But the main components you will need include the following:
- Solar modules
- Charge controller(s)
- DC Disconnect Switch
- Backup Generator (Optional)
Now, let’s tell you more about these components mentioned above.
This component, commonly known as solar panels, uses solar energy to create electricity. When sunlight hits them, they produce an electrical charge to power up the batteries for your home use.
This item has several batteries wired to each other to store energy from the sun. Thanks to the battery bank, the off-grid solar system can power up your electronics for hours.
Solar Charge Controller
It is commonly called the charge or battery regulator. The name of the device perfectly defines its function. This component controls the current that enters the battery bank, and it prevents overcharging.
If you want the battery bank to last longer, you need to get the best solar charge controller. However, if you are using a battery-based inverter, you don’t need to get a charge controller. The reason is that it features an integrated controller.
The inverter converts DC to AC, particularly in appliances that run on electricity. Unlike inverters that use the grid, the off-grid models do not need to match phase with the utility sine wave. Instead, it converts the current from the solar panels into DC. But before this process, the current will pass through the controller and battery bank.
DC Disconnect Switch
Every solar system should have AC and DC safety disconnects. But for the off-grid system, you will need to get an extra DC disconnect installed between the off-grid inverter and battery bank. The DC Disconnect Switch helps to cut off the current flow between these components, thus preventing damages or fire outbreaks.
Can I Get Solar Panels and Install Them by Myself?
Yes, you can purchase, install, and maintain your off-grid solar system without any assistance. But it will be advisable you seek guidance from an expert. The reason is that setting up solar panels requires more skill than changing a light bulb.
Creating a homemade solar system might look extra hard. But people claim that this DIY project is quite easy. Luckily, anyone can get tips from YouTube videos or online tutorials.
When you fix a solar panel by yourself, you cut costs and learn how to fix things. But to avoid any problems, skip the DIY idea and look for a professional.
So why should you ignore the self-build option and choose an experienced hand? First, poorly installed panels can make you spend excess cash. Besides, there are local laws that you must adhere to before setting it up, and you also need to know the perfect angle to position it. Also, you will need an expert to determine if the roof can hold the weight of the panels.
Some brands provide solar components that have easy-to-use features. For instance, these models might have cables that you connect to a compatible port. Since they come in the same package, finding the dedicated slot for each cable won’t be difficult.
Moreover, every item has labels, thereby making it easy for first-timers. To set up this type of system, you need to know how to carry out the following steps:
- Securing bolts and screws with a screwdriver and wrench
- Carry the item weighing up to 75 pounds. If they feel heavy, get an extra hand from a friend.
- Make holes and add concrete that’s if you’re constructing ground mounts
- Connect the system to your electrical service panel
- Set up and connect the solar inverter
And that wraps it up!
Your Next Step…
Now you’ve seen how you can use solar to reduce your bills significantly.
But here’s the thing.
Trial and error, and going at this alone is going to cost you.
Want to avoid that?
Then I recommend you get a copy of Smart Solar Box.
It’s easy, quick, and best of all shows you exactly how to create the home solar system you dream of…
And make it a reality.
