What Is An Off Grid Solar System And Who This Is For

best-off-grid-power-systems

Solar power systems are great alternatives to your typical electrical systems. Aside from obvious benefits like energy-efficiency, solar power systems are also cheaper and are friendlier to the environment.

There are three types of solar power systems: 1) on-grid, 2) off-grid, and 3) hybrid solar systems. This article will tackle and focus more on the second type, the off-grid solar power system.

As in their name, solar power systems like a home off grid solar system operate on solar power. They then convert that solar energy into electricity.

Also called stand-alone power systems, off-grid solar systems are basically not connected to any electrical power grid. Because of that, they are equipped with a high-capacity battery bank to store the electricity harvested by the solar panels.

Because of the battery storage, an off-grid solar system is perfect to use in long winters, during adverse weathers or emergencies. During these conditions, there is a high possibility that power outages will occur which can sometimes last from hours to days to weeks.

With an off-grid solar system, your home will not be affected since the system can provide electricity for you. Just make sure that your solar system is designed to have the capacity to meet the electricity needs of your home.

This type of solar system is also perfect to use in remote areas located far from the local electrical grid or in areas that are prone to power outages.

Examples of these places include hunting cabins, off-grid homes, bunkers, rural and developing communities, far-away places, signs, outbuildings and the like.

How Does It Work

An off-grid solar system works by collecting solar energy via the solar array that is made out of silicon photovoltaic cells that are linked together. Just how many and what type your solar panel depend on your location and your energy consumption.

To get maximum production, ensure that your solar panels are installed safely and strategically. Aside from collecting solar energy, it also converts it into DC power.

DC energy is then stored in a battery bank, which is group of batteries, that are wired together. It is recommended that you get a model that comes with a battery monitor. That way, you can effectively track and supervise the status of your battery bank as it provides you with information, such as the status, the charge and the maintenance.

Another way to protect your battery bank is by installing a solar charge controller. This allows you to regulate the voltage and current your battery bank receives from the solar panel. That way, you can protect your battery from damages.

After that, DC power is then converted into AC via your solar inverter. DC power is not usually used by your common appliances, hence, the need to convert it. A stand-alone inverter is highly suggested in off-grid solar systems.

Once it is converted, AC power is then used immediately by your appliances and other electronics. In cases of excess, it is then converted again into DC energy and stored inside the battery bank. In this way, you can use the energy saved up by the battery bank even during nighttime.

Lastly, a good small off grid solar system needs a back-up generator. In case of emergencies, or during long winters or overcast days, the back-up generator provides an alternative power source. This way, you will still have a continuous supply of electricity. A diesel-powered generator is typically suggested.

What Are The Different Types Of Off Grid Solar Systems

best-off-grid-solar-power-system

There are typically five types of off-grid solar systems. Before you purchase and set up your off-grid solar system, it is important to know more about the product. This article will explain the different systems.

DC only system

DC only systems are smaller that are designed to power mainly lights and low energy consuming devices like your monitoring equipment. They are also perfect to use on DC-powered appliances having 12 voltages or lower.

This system either uses a solar panel or wind generator that generates DC power. This power is then used to charge the battery bank.

Here, there is no solar inverter. DC power is directly fed to your lights and/or appliances. This system typically has no back-up generator; hence, you need to ensure that your system is sized to handle your loads in emergency situations.

Mixed DC and AC system

This hybrid system is similar to your DC only system but with the addition of an AC inverter. This is still designed for powering light or low energy equipment.

With the AC inverter, you are able to power appliances that have 230 volts.

Nevertheless, since it is a small system, there is also no back-up generator. Thus, it must be designed in such a way to ensure that it can handle your loads during emergencies.

AC only system

This system is designed to handle bigger loads and is equipped with a solar array rather than one solar panel. The solar array collects solar energy and then converts it into DC power. This power is then stored into the battery bank.

With the solar inverter, the DC power is converted into AC power that can be used to run your typical household electronics and appliances.

In this type of system, a back-up generator is also absent. Hence, you need to ensure that your system can handle your loads in case of power outages and emergencies.

AC system with wind and solar

As in the name, this off-grid solar system runs on two sources of energy: solar and wind energies. The solar array collects and converts solar energy into DC power which is then stored into the battery bank.

During cloudy days, wind energy is collected via the wind turbine. It is then converted into DC power and stored in a battery bank.

DC power is converted into AC power via the inverter and is fed to your home appliances.

AC system with back-up generator

This system is just your AC system with the addition of a back-up generator. It works on the same principle. However, with a generator in hand, you have an advantage. Your home will be able to have a continuous power supply even during emergencies or power outages.

Generators are powered through diesel, petrol or LPG.

Advantages And Disadvantages Of Off Grid Solar Power Systems

Knowing the advantages and disadvantages of a product is needed to make an informed choice about it. with this, you’ll know what to expect and be ready in cases of damage.

Like all devices, an off-grid solar system has its own share of advantages and disadvantages.

Advantages

Reduce electricity costs

One of the main advantages of solar systems is the reduced electricity costs. For one, solar energy is free unlike your electricity. This is especially advantageous to people living in sunny areas.

Moreover, you can also save in terms of oil and gas prices. Since you rely on solar power, the continuing rise on fossil fuels won’t bother you.

Environment-friendly

Since off-grid solar systems rely on solar power, they are also the friendlier choice in terms of the environment. Not only is it cheap, you can also do your part in saving the environment by going solar. Moreover, you can reduce your own family’s carbon footprint.

Great for remote areas

Off-grid solar systems are also beneficial to those who live in remote areas. Instead of spending on extending your power lines, you get to save by living off the grid. You also have the freedom of choosing where you live since you can generate your own electricity.

Emergency-ready

Living off the grid is also suitable for those in areas that are prone to power outages or have power failures.

With this, you would not have to suffer through days or weeks without electricity since you will be able to have a continuous power supply. Just make sure that the energy stored in your batteries is enough for your consumption.

In case it isn’t, opt for an off-grid solar system that comes with a back-up generator. that way, you’ll still have electricity when your battery bank runs out.

Low maintenance

Off-grid solar systems are generally sturdy and do not require a lot of fuss in terms of maintenance and aftercare. You just need to clean the body a couple of times and they’re still good as new. The only components you need to change are the cables, the inverter and the battery bank. However, each of them has a generally long lifespan, the shortest being 5 years.

Moreover, these systems generally have long warranties (about 20-25 years), so in cases of damages, you can always return them.

Disadvantages

High Initial Price

Since it is still fairly new technology, the initial cost of off-grid solar power systems is initially high. In fact, according to a study, the high upfront costs of off-grid solar systems are one of the reasons why households get discouraged of living off the grid.

For them, it is still better to purchase a small solar system to save a little bit on electricity but still generally rely on the grid for their needs.

Bulky

If you want to produce and store more electricity, you would typically need to upgrade and install more components to your off-grid solar system. For one, solar arrays require a lot of space on your roofs. If you install it on your yards, it might not produce enough solar energy.

Aside from the costs, your system would definitely occupy a huge amount of space that may not be feasible for some homeowners.

How We Picked And Tested

simple-off-grid-system-reviews

Just like when buying off grid solar batteries, you must carefully consider your options on the available off-grid solar systems on the market to ensure that you’re making a good decision.

A good off-grid solar system is one that is fully capable of handling your load and one that is made out of high-quality materials. To ensure that you get the best quality for your money, consider these steps.

Calculate the load

Before you buy the components to your off-grid solar system, you must first calculate the total load of your home. This number is important to know since it dictates the quality and the power of your other components.

To start, you need to choose what devices you want to run and calculate how many hours they will operate. After that, check their specification charts for their respective ratings.

Then, get the watt-hour for each device by multiplying the power rating by the run time. Then, get the total watt-hour by adding all the watt-hours of your appliances.

Now that you know your total load, it’s time to choose your components.

Battery

First, you need the battery to store the electricity. There are different types of batteries available in the market. Choosing one depends on how much storage you need, the number of appliances you wish to run, and the amount of power sources you have.

For solar systems, lead acid batteries are suggested. You can also use Ni-MH or lithium ion batteries if you’re only powering a small load.

Moreover, as a larger system requires a bigger bank and vice versa. If you only want to power low energy consuming devices, then a 12V battery bank is suggested. However, you want to use 24V to 48V if you wish to power 200 watts or more.

Most households typically use batteries ranging from 12 volts to 24 volts.

Solar Panel

To get enough energy to satisfy your load component, you need to ensure you get enough “sun hours”. Sun hours refer to the number of hours the sun is shining on your solar panels. With this, you’ll have an estimate on how much solar power you can generate.

There are different types of solar panels: monocrystalline, polycrystalline and amorphous. The crystalline solar panels are generally more preferred since they generate a decent amount of electricity. In fact, out of the three, the monocrystalline panels generate the most electricity; however, they are also expensive. On the other hand, amorphous solar panels are perfect for small loads.

The number of solar panels depends on your location and the time of year. If you live in cloudy areas or places that have winters, consider getting a generator for back-up power.

Charge Controller

A charge controller regulates the voltage and current as to protect the battery. Like the other components, there are also different types of charge controllers: On/off models, PWM and MPPT. Choosing one depends on the number you get after diving the watts from the solar energy by the battery’s voltage.

However, as a rule of thumb, choose between PWM and MPPT since they are the most efficient. In fact, the MPPT is the most efficient; however, they’re also expensive.

Generally, a PWM charge controller is suggested if the solar array is equal to the battery’s voltage. So for example, for 200 volts or above, you must use an MPPT charge controller.

Inverter

If your appliances mostly run on AC power, then you need an inverter. An inverter converts the DC power you get from the solar panel into AC power for your appliances to use. However, if your appliances are DC powered, you can skip this step.

To know what inverter to get, know first if your devices use either 120V or 240V. This also depends on the voltage of your battery bank. Some inverters are stackable and can be wired together.

There are different types: square wave, modified sine wave and pure sine wave. A pure sine wave is generally preferred since it is the most efficient and is suitable to all devices. Moreover, it also protects your items and is also safe.

On the other hand, the square wave is the cheapest but is only suitable to select devices whereas, the modified sine wave inverters is not suitable if you’re planning to power powerful appliances such as refrigerators, ovens, and the like.

Balancing the system

Aside from getting the essential components, you also need these to balance the system. This includes:

  • Breaker boxes
  • Solar panel mounts
  • Wires
  • Fuses and breakers

Back-up Generator

A bonus component is the back-up generator. If you are living in areas where there are long winters, or there are typically overcast days, or in remote or rural areas, then investing in a back-up generator is a great idea.

In case the sun will not be available, the back-up generator will be there to power your home. They are powered by different fuels such as diesel, gas or the like. Choosing one is usually a matter of preference for the user.

What are the most trusted off grid solar system brands?     

There are many off grid solar system brands, so it can be hard to compare which one the best for you is. For an idea, some of the best brands include ECO-WORTHY, WindyNation, ECO LLC and Renogy.

How to build an off-grid solar system

After purchasing all the components required, it’s now time to set-up your off-grid solar system. You can always ask and call for professional if you are unsure, but if you want, you can install the system on your own.

  1. Mount your Solar Panel

Before mounting it, first choose a location where the solar panel can get the most sunlight. You can install it either on your rooftop or on the yard provided that there’s nothing to obstruct its view.

As for the mounting stand, you can either purchase or make your own. Make sure that you tilt them in an angle that will obtain the most sunlight. You can use a compass for this step to know what direction to mount your panel.

After that, you can choose to pour concrete on it to ensure its durability. Otherwise, you can skip this.

Thereafter, you mount your solar panels and proceed to wire them.

  1. Series and Parallel Connection

This is especially when the solar panel and battery bank is purchased separately. You have to wire these two components together to match the system. You can choose either series or parallel connections, according to your preference.

In a series connection, you connect the end of one device’s positive terminal to the other’s negative terminal. Remember, that the individual voltage of each device adds up and the current doesn’t change.

In a parallel connection, you connect one positive terminal to the other and one negative terminal to the other. With this, the voltage is constant but the total current of the unit is the sum of the devices.

  1. Stand

You can also choose to place your inverters and battery bank in a stand to protect them. Like the solar mount, you can choose to either buy one or make one.

  1. Wiring

Next step is wiring all of your components together. First, wire the charge controller to the battery bank for it to get used to the voltage. You will know when you’ve successfully installed it when the charge controller’s indicators light up.

Next, connect the controller to the solar array via a MC4 connector. Then, connect it to the DC load or light for the final step.

If you want, you can place additional switches and fuses for added protection.

  1. Logging

If you want to know the energy production or consumption, then you can also install energy meters. This way, you can track and monitor your production and consumption.

What is the warranty?      

Just like any other products we buy, an off grid solar system does not come with the same warranty. Some may have one year and others five. It depends mostly on the manufacturer of the product. Compare it for peace of mind when finding an off-grid solar system.

What are the best places to buy?

You can find these products in different stores like clean energy product shops and other home improvement stores. However, you might want to get yours at Amazon. Com if you want the best deals and prices. In the online marketplace, you can also buy from the manufacturers themselves.

How to install and use?    

Refer to the specific product you bought. Instructions for installation vary from one model/brand to another. Check them out for your guidance before installing and using the off grid solar system.

How to care & maintain?  

Just like in installation, care and maintenance can be specific from one manufacturer to another. Thus, you should check the user manual included in your purchase to ensure of proper usage, storage and maintenance, among others.
