What Exactly Is a Solar Generator?
A solar generator consists of batteries, an inverter, and a charge controller.
This device charges itself through solar panels that run current through the charge controller and into the battery.
The inverter emits the power generated from the charged battery to charge numerous devices ranging from smartphones, laptops, lamps, lights to refrigerators, TVs, and even your RV.
Solar Generator Buying Guide
Now that you’re aware of the best options available in the market, let’s look at the essential aspects you need to consider before you make the final decision.
Factors to Consider While Selecting a Solar Generator
Here are some of the factors you need to consider while shopping for your solar generator.
Note the amount of electricity your generator is capable of holding, similar to a water tank.
Battery capacity for solar generators is measured in watt-hours (Wh).
Also, you have to determine the amount of power that the battery can generate at any particular time, which is usually noted in watts.
You don’t have to hunt for the largest battery in the market to get a good solar generator. All you have to question is:
- If the generator delivers sufficient power output (in watts) for your needs
- If the battery is big enough (in watt-hours) to where you don’t have to constantly charge it
As you are searching for the battery type essential for your power station, you will find that there are two main types available in the market.
The two most common types of batteries present in portable solar generators are as follows:
- Lithium-ion battery
Since 1991, these rechargeable batteries have been commercially available in the market. They are well known for their extended life span, energy-dense features, and easily rechargeable formats.
- Lead-acid battery
These batteries are the same as a traditional car battery, which is inexpensive. Moreover, it’s quite heavy and has a shorter life than lithium-ion batteries. For long-term energy storage in a home unit, they act as a powerful backup source.
Size & Weight
Several solar generators are lightweight and smaller in size than traditional gas generators. However, you may also come across some brands that are quite bulky and big, as seen from the Point Zero Energy Titan and YETI 3000 Lithium.
Based on what you’re planning to use the generator for, you can select the size that you prefer. In case you wish to take it to the woods as you go camping, it’s important to get the best generator for you that has a great power output but also is lightweight and compact.
However, if you’re planning to charge your refrigerator or other large appliances in case of a power outage, getting a small solar generator will not be helpful.
While hunting for solar panels and solar-powered generators, you will have to pay careful attention to the wattage rating present on the solar panels.
This is otherwise known as the solar PV input. For instance, the PV panel of 100W is theoretically capable of generating 100W of power when kept directly under the sun.
However, this is almost never the case due to efficiency losses from the panel.
Usually, the full sun rays are between the timeframe of 10 AM to 4 PM. Sunlight may still be available after that 4 PM mark; however, the PV input won’t be as high as earlier in the afternoon.
Benefits of Using Solar Generators
Solar generators are famous for their benefits when compared with traditional fossil fuel generators. Here are some of the benefits that the solar-powered units have to offer.
Free of Emissions
These units are free from all sorts of emissions. I’m referring specifically to anything coming from the generator. Since it’s simply powered by a battery, you can easily use a solar generator inside any space/room.
However, if you’re planning to plug them into an AC wall outlet, it technically won’t be free of emissions as the power outlet most-likely gets at least part of its energy from coal power stations.
Whereas when you charge it from solar panels, it obviously becomes an eco-friendly option.
This is mainly because it does not generate any carbon dioxide, carbon monoxide, or any other toxic gases as combustion does not take place to generate power.
If you want to get really technical, solar panels are manufactured in a pretty toxic process. If you’re looking to purchase solar panels with the least amount of carbon footprint in its manufacturing process, look for solar panels made in Europe and the USA. This is because “a solar panel produced in China will have double the carbon footprint than one produced in Europe.”
Zero Noise Pollution
On using the solar generator, you will find that they are nearly entirely silent. It does not produce any noise other than the fans used to cool down the generator’s components.
A few solar generators can create noise at times if they are used to their limits (due to the cooling fans), but this is usually not the case of many solar generator users if they understand the limits and capabilities of their systems.
Other than this factor, solar generators are nearly entirely silent when used within their power limits.
This silence is mainly because the energy used for charging your gadgets comes from the batteries’ stored power, which emits a smooth discharge.
When you compare it with gas generators, the volume of noise from the system depends on the combustion of the internal motor present, which can produce rattling sounds that are quite noisy.
If you prefer to use a generator that does not make any noise, opting for a solar generator would clearly be the best choice.
Since these power stations do not come with numerous moving parts, you won’t have to worry about facing maintenance issues.
You will find that these generators are mostly square-shaped with several sizes of battery packs that are carefully concealed with durable plastic exteriors. Many solar generators also have rubberized bases that are easy to clean.
All you have to do for solar generator maintenance includes four steps:
- Wipe the exterior clean to keep it free of dust and dirt
- Change the battery or replace the generator after 5-10 years of use (depending on how much you use it)
- Keep the generator stored in a cool, dry area
- When in storage, either keep it continually charged with a wall adapter, or charge it every 3-6 months depending on the specifications of your generator
An issue that several lithium-ion solar generators have is their inability to swap out batteries when they are completely used up.
With lead-acid solar generators like the YETI 400 and 1250, they have replaceable lead-acid batteries that are reasonably priced. However, if you try to find replaceable batteries for a YETI 1400 Lithium, for example, you will see nothing there.
This is an important factor to consider, especially for people who are using their lithium-ion generators frequently. Goal Zero is not the only company that follows this trend. There are several manufacturers that do not have replaceable batteries for their systems.
What happens if your lithium-ion solar generator runs out of battery charge cycles? In most cases, you will need to replace the entire system. This is why knowing the lifecycles (or charge cycles) of your lithium-ion system is very important.
There are some solar generators that are void of this issue, and they are the Titan and the Flex generators. They have a modular design that allows many batteries to be stored underneath the system. If a battery goes out after years of use, then you can simply purchase another battery from their company to keep your system going.
Long Term Investment
You will find that the initial cost for these generators is quite expensive, especially when you buy solar panels along with the generator.
However, in the long run, they are sure to pay off. This is mainly because you won’t have to purchase gas, diesel, propane, or natural gas.
Also, you obviously don’t have to worry about paying for the energy that the solar panels bring into the generator.
For instance, a gas-powered generator requires about one gallon of fuel for every eight hours of use.
In case you’re planning to run the generator for about 24 hours each week, you may require around 156 gallons of gas annually. This can result in a fairly significant expense over time.
However, by using a solar generator (other than the initial cost of the unit and the solar panels), you won’t incur many expenses. This will help you to calculate the price between the fuel and solar variants long-term.
Suitable for Indoors
Since solar generators do not release any poisonous gases like carbon dioxide or carbon monoxide and create little to no sound, it is a perfect addition for indoor purposes.
You’ll find that in addition to your house, you can use them inside your tent while you go camping. You will also find it useful for your RV and even inside the car for using a portable heater in case you get stuck on the roads during a snowstorm, for example.
Remember that there are numerous situations and places where you can use a solar generator instead of a fuel generator.
Easy to Use
These gadgets are easy to use, as all you have to do is plug it into your power source of choice and get it charging.
This includes either a solar panel, your car port, and/or an AC wall outlet. Several solar generators can be charged using a combination of the three charging methods, resulting in faster charging speeds.
Next, if you wish to power any of your appliances, all you have to do is check the wattage requirement and plug it into the generator.
Frequently Asked Questions
- How Does a Solar Generator Work Efficiently?
A solar generator functions similarly to a fossil fuel generator in that it provides power to appliances and electronics. However, a solar generator gets its power from the sun or power outlet instead of a combustion motor.
With the help of the solar panels that contain photovoltaic cells, it absorbs energy from the sun’s rays to produce current. The current produced helps in charging the batteries, which are the main components of the solar generator.
What makes a solar generator efficient lies within its main components:
- Solar panels
- Charge controller
A lithium-ion battery has an extremely high charge/discharge efficiency compared to other types of batteries and generators. With a high-quality inverter, the battery is able to convert DC to AC power with a small amount of power consumption.
Solar panel efficiency is dependant on the solar cells used, but on average produces 15-27% cell efficiency.
This is clearly a low percentage and is due to the power transfer from the panels to the battery. But with an MPPT charge controller, a solar generator can capture more power from solar panels than with a PWM controller.
Overall, knowing the internals of a solar generator is important to determine how efficient it is. A generator with high-quality parts determines how efficient it will be.
- Can You Re-Charge Your Solar Generator on a Cloudy Day?
If you are someone who uses only solar panels for charging, then a cloudy day can diminish the quantity of charge your panels can produce. This, in turn, also decreases the speed at which your batteries will recharge.
However, you can use other methods to revive the battery. This includes plugging it into the car port, using the AC wall outlet, or even plugging it into another generator.
- Which Solar Generator Is the Ideal Size for Me?
The critical aspect you need to note while selecting a solar generator is what exactly are you planning to use it for. This is because they vary significantly from compact and lightweight to bulky and heavy.
As you hit the road, small solar generators make a perfect power back up when you wish to charge your laptop or smartphone.
Do you wish to use it as an emergency power backup at your house in case of blackouts or massive power failures?
Then you will have to research carefully and opt for one that has a higher output that will help you charge most of your essential household appliances.
- What Devices Can You Power With the Help of a Solar Generator?
There are several devices that you can plug into a power source that can be easily charged using a solar generator.
However, look out for the wattage output of the power station and compare it with the watt requirements of the appliances you’re plugging it into in order to find out how much power it will require.
At times, the portable unit may not deliver sufficient wattage to charge specific gadgets. For example, an outlet that produces 100W and peaks to 150W will not give sufficient power to work a hairdryer that needs around 1500W.
If the input and output power requirements are measured correctly, you won’t face any powering issues.
Selecting the best solar generator not only provides you power during a camping trip or power outages but also can save your life during emergencies like natural disasters.
Based on your budget and requirements, there are solar generators that can simply power small devices like phones all the way up to power tools and full-size refrigerators.
