How to Choose Off Grid Solar Systems?

In this write-up, you will learn about the best off-grid solar systems.

But first:

What are off-grid solar systems? Additionally, can you rely solely on the off-grid systems and completely discard the on-grid system?

Before we dive into the reviews, let’s first explore the main differences between these two solar systems.

In this case, off-grid means disconnecting your home completely from the national grid. It means going 100 percent on solar, significantly reducing your energy bills!

On the other hand, an on-grid solar system means that your solar power is connected to the main grid. In other words, you can still access mains electricity. However, for off-grid systems, you depend on the sun and the power stored in the batteries.

What to Consider When Buying the Best Off-grid Solar System


If you have decided to go completely off grid, you have made the right decision.

You can go off grid using wind power, that is, if you come from a high wind area. In addition, you can also use solar power. On the same note, you can use a combination of both, you know, a hybrid system.

However, in this case, we are going to find out how you can buy the best off grid solar system. Of course, with so many of these systems in the market, getting the right one can be confusing.

Here are the top factors to consider:

Choose according to the material used

Solar panels may look the same or slightly different to inexperienced people, but they are not the same. They come in the following types:

Monocrystalline solar panels

These are the most popular solar panels. You will know them by their black color. In addition, they are more efficient than other solar panels, for instance, polycrystalline ones.

The solar cells are made from a single silicon crystal, hence the name “mono.”

Polycrystalline solar panels

You will be able to tell the polycrystalline off grid solars from the monocrystalline ones by their blue color. However, these solar panels are made from many crystals of silicon, hence the name polycrystalline.

While polycrystalline solar panels have a lower efficiency as compared to monocrystalline ones, they are cheaper. Besides, the difference is not that much. For instance, they have an efficiency rate of 17 to 19% while monocrystalline ones have 18 to 23.5%.

Amorphous Solar Panels

These are thin-film panels. Although they are large, like some monocrystalline solar panels, they perform very well in direct sunlight.


Your solar panels will give you DC power. However, your home appliances use AC power. Therefore, you will need this inverter to convert the DC power to AC power.

Of course, most of the off grid solar panel systems come with inverters and if they do not, you will need to buy one separately. On that note, there are different types of inverters.

Some are huge, some are string types and yet others are micro in size. However, if the solar system does not come with one, you can always check with the solar panel manufacturer about the best inverter to buy.

Charger Controller


This is another very important component of the off grid power systems using solar energy.

If you live in a sunny area or you have a high capacity solar panel that harnesses a lot of energy, you need a solar charge controller. You need this gadget irrespective of your solar system size.

This device controls the amount of current and voltage that is going to your battery. In addition, when the battery is full, the charge controller will not allow more current to pass. However, as soon as the battery is dispensed a bit, the charger controller will know that and allow the solar to continue charging.

The Budget

To tell you the truth, going completely off-grid with solar is not going to be cheap. Therefore, you may need more solar panels compared to a person who wants an on-grid solar system, depending on your energy requirements.

Since you will need more solar panels, you will need a higher budget. In addition, you will also need solar panels with higher output and this can cost more. If you add the other components such as inverters and batteries, you can see just how much the budget will hike.

Depending on the size of your home, you could need small or big solar panels. For instance, if you have decided to reduce your carbon emissions by living in a tiny home, even a 200-Watt or 300-Watt solar panel, one deep cycle battery and charger controller can be enough.

To come up with a proper budget, you need to find out how much power you will need. This includes determining how much power your appliances and lighting fixtures consume.

To give you a proper estimate, you can expect to spend at least $500 for a complete 200-Watt off grid solar system for your small home.

Installation Cost

You could install your off-grid solar system on your own and save the installation costs. However, it is better to hire a technician to install it for you.

In addition, you might also need to buy extra hardware from the store. For example, if you want to install the solar system in the backyard, you might need a mounting rack.

If you are going to install the solar panel on the roof, you might need extra installation hardware. Of course, most suppliers add the installation hardware such as screws, lead wires and others. However, in some cases, you will find that the screws are of lower quality.

The initial cost of buying and installing complete off grid solar kits with batteries is costly. However, after that, you can have a free run (literally) until you need to replace the off grid batteries.

Frequently Asked Questions


Going for the complete off-grid solar system can be a hard decision. Therefore, you need to know as much as possible about it. Here are some of the most frequently asked questions:

How many solar panels do I need to be off grid?

It depends on the size of your home and the appliances that you need to power. For instance, you should find out how much output one solar panel could give you.

In addition, if a solar panel has an output rating of 200 Watts, it will do about 170 Watts. Therefore, you can divide your overall consumption by the output of one panel. That way, you will find out the number of solar panels that you will need.

What do I need for an off grid solar system?

You will need a full solar system kit. Usually, this involves the solar batteries, the solar panels, an inverter and charger controller. In addition, you might need an installation rack if you want to install the panels on the ground. On the same note, your kit will come with the required cabling.

How many batteries do I need to go off grid?

Again, this depends on the size of your home and your solar power needs. However, most experts recommend that you have a 24 or 48-volt battery system. Therefore, you might need two, three or 4 battery banks.

The capacity of 24-volt batteries can vary, typically starting around 600 Amp-hours, with some models offering capacities much higher, potentially reaching up to 6000 Amp hours or more depending on the battery type and manufacturer.
