Are you thinking of getting an off-grid solar system? These systems have become incredibly popular as of late because they’re both economical and eco-friendly. They’re great alternatives to your traditional electrical systems, and off-grid solar systems operate entirely on solar power.
These systems aren’t connected to any electrical power grid, and instead, they have a high-capacity battery bank that helps store the electricity that’s absorbed by the solar panels. Since they’ve got excellent battery storage, off-grid solar systems can be used as a backup in inclement weather and emergencies. It’s also great for those that live in rural areas and are situated far away from the local electrical grid.
If you’re new to purchasing an off-grid solar system, you might not know where to start. There are plenty of options out there, and a few things you’d need to consider when purchasing your off-grid solar system. To help, we’ve put together a list of 6 of the best off-grid solar systems. We’ve also put together a guide that’ll help you with choosing your off-grid solar system.
Benefits of Off-Grid Solar-Systems
The most significant benefit of off-grid solar-systems is that you won’t have to worry about power outages. Since you’re not tied to the city’s power source, you won’t have to worry about disruptions caused by inclement weather or damaged power lines and equipment. With off-grid solar-systems, it stores solar energy into batteries and is a standalone system and won’t be affected by power outages.
Another great benefit is that it helps with reducing electricity costs. Although you’d be forking out a little more money initially to purchase the off-grid solar system, you’ll be saving money in the long run, thanks to the low monthly rates and maintenance costs. Since your system will also only be relying on sunlight to produce energy, you don’t have to pay any monthly electricity bills, and the only purchase you’d need to factor in is the changing of batteries.
The installation system of off-grid solar-systems is also much easier because they don’t have a complex infrastructure. All you need is some tools, and you’re good to go, you won’t have to fork out extra money to pay for a professional and can do it yourself.
If you live in a rural area, off-grid solar systems are also a great choice. Since there’s less advanced infrastructure in those areas, the chances of blackouts are more common. An off-grid solar system can help make your home self-sufficient and more independent from the inconsistency of city power.
Finally, you’re doing your part for the environment with an off-grid solar system. They’re much more environmentally friendly than fossil fuel power and will help reduce the overall carbon footprint.
Pros and Cons
- Cost-friendly. Solar energy is free so that you won’t have a hefty electricity bill, and there’s minimal maintenance required.
- Eco-friendly. These systems rely on solar power, so you’re doing your part for the environment.
- Great options for rural areas. If you live in a rural area and commonly experience blackouts, off-grid solar-systems are a great choice as you’re generating your own electricity.
- Great for emergencies. Even if you’re not living in a rural area, you can take comfort knowing that you’ve got backup power in case of an emergency.
- Easy to maintain. Off-grid solar-systems are sturdy and don’t require much maintenance, all you need to do is occasionally clean the body and change the battery bank.

- Bulky. You’ll need quite a bit of space on your roof to install an off-grid solar system.
What to Look for in Off-Grid Solar-Systems
The first thing you’d need to do is calculate the load. You must figure out a total load of your home, as it’ll dictate the overall power and quality of your off-grid solar system. Next, you’ll want to consider the battery that the system uses to store the electricity. There are different types of batteries available, and it depends on the number of appliances you’ll be running and the number of power sources you have. Usually, however, these systems will use lead-acid batteries, and a larger system will require a more significant bank.
Another thing to consider is the solar panel. You’ll want to make sure that you’re getting sufficient solar energy, and that’s determined by the number of hours the sun is shining on your solar panels. There are different types of solar panels available, and the most popular is monocrystalline solar panels. These generate the most electricity, but they can be pricey. For smaller loads, amorphous solar panels are a great choice.
You’ll also want to take a look at the charge controller as it regulates the voltage and current to protect the battery. There are different types of charge controllers, but you’d usually want to look at PWM and MPPT as they’re the most efficient. If your appliances mainly run on AC power, you’d also need an inverter. The inverter you purchase is highly dependent on the devices you use and the voltage of your battery bank, so that’s something you’d need to take a look at.
Aside from all those components mentioned above, you’d also need to balance the system by getting other essential elements such as breaker boxes, wires, fuses and breakers, and more. Finally, you may want to consider getting a backup generator. Just in case you deal with cloudy or rainy days, a backup generator will be there to power your home.
