Factors To Consider When Buying A Solar Generator

A solar generator is technically packed with three major elements — a solar unit, power storage and portable design.

But design-wise, you have to remember that the device has no specific form and its main function is to collect solar energy and store it to provide you power without any troubles.

There are indeed so many types of solar generators in the market today but below are the factors you need to consider when choosing or buying one.

1. Portability and Compactness (Weight, Size, a nd Shape)

Source: Jerusalem Post

Perhaps not the most important factors to consider for some, but the solar generator’s weight, size and shape matter where you intend to use it. If you plan to go hiking or camping, then choose a unit that is not heavy.

Most of the solar generator application requires a degree of portability, which is the true value of a solar power system. So, it’s best to pay close attention to the weight.

If you’re planning to go off the grid, a larger solar power unit’s required that can be stored in a cabin or RV. Always remember, the proper weight distribution will secure the ability for portable solar generators to be used off the grid and pushed easily on location.

As for the shape, solar generators come in several shapes. Some are foldable and can be easily stashed away while others are in heavier boxes and on wheels for easier transportation.

2. Charging Times

This factor is often overlooked but the amount of time it takes to charge a generator is something to consider. So, look into the device’s charging times and compare it when plugged into a wall outlet and when placed under direct sunlight.

3. Wattage

The wattage of the portable solar power system could be as low as 4 watts to as high as 1,500 watts. Take note, never purchase lower wattage systems just to save money because the lower the wattage, the longer it takes to charge. In cases of emergencies, the cost is nothing if it can deliver ample power that you need.

4. Battery Storage Capacity

A solar generator’s battery storage capacity is the most significant factor when it comes to the actual usability of the device. The battery storage refers to the allowable amount of power to be used at night or when your energy needs exceed the amount of solar power input.

By knowing solar generators usable watt-hours, you can determine the time needed to run specific applications. it’s recommended, however, to only use 70 percent of the full capacity of traditional lead acid batteries in order to reserve life span and reduce the failures.

5. Solar PV Input

The Solar PV input is responsible for powering a solar generator. With enough solar PV input, it provides continuous power during the day and low recharging after the night usage.

A solar generator will allow for the solar tracking, which is the ability to move your solar panels to capture the best solar input. PV input is directly related to the storage capacity of a solar generator, meaning using the solar generator while it’s recharging will increase the time to reach its full capacity.

6. Component Quality

Quality is a major factor to consider when purchasing a solar-powered system as it affects the usability and durability of the product. Hence, it’s important to know the product’s component warranties and capable life spans.

Durability is often negatively affected by the component quality. So, buying a solar generator with a metal casing will assure you that the product could withstand rigorous use and continue to protect the valuable components over time. Always remember that owning an alternative power source demands a need for reliability.

7. Inverter Rating

Source: My Solar Power

Most solar generators use the inverter rating as the overall generator rating based on what you can pull from the unit. But inverter size is not dependent on the capabilities of the product.

For example, a 1500 watt inverter with one 100Ah battery could be useless since it would deplete the battery in around a half an hour (800/1500).

Solar generators that have at least a 1.5:1 usable watt-hours-to-inverter-rating ratio (1500Wh to 1000 watt inverter) are considered the most usable, the best and the most reliable ones.

But remember to watch out those with big inverters but with little to no battery storage and those without inverter external charging capabilities.

Inverters, which converts low volt DC to standard 120 volt AC power, rate the maximum watts you can pull at any one time from a solar generator. For example, a 1500 watt inverter lets you pull up to that wattage in AC power.

However, it should be noted that pulling the maximum watts from an inverter depletes lead-acid batteries at a faster rate (lithium batteries protect against this effect).

8. Balanced System Design

When it comes to usability, another important factor to consider is the balanced system design, which refers to the key combination of usable storage capacity, solid PV input and appropriate inverter rating.

In actual terms, 1500 usable watt-hours are the standard for storage capacity that can handle most solar generator applications. To balance the system out, it’s ideal to have a 250 watts PV input and a 1000 watt inverter.

With the combination of high-quality components and balancing the system design to boost portability will assure that a solar generator can work in a variety of environments, applications, and needs. However, watch out for devices that lack any of the key components and those with disproportionate ratings.

9. Accessories

When searching for various units, always pay close attention to how and where the power is stored. For solar power systems, there might be a need to purchase separate accessories like USB plugs or wall-style sockets while some systems just need the basic ones such as alligator clips and an external battery.

10. Sound

One of the reasons why people opt to use solar generators is the need to ditch the noise that comes from fuel generators. Hence, it’s important to choose a unit with low decibel level.

11. Price

Along with other purchases, the cost of solar-powered generators is also an important factor to consider. We highly recommended that you make a budget and determine your power needs.

Remember, a solar powered generator is also an investment so it needs to be treated as one. But aside from the price of a unit, what others are saying in reviews are equally vital in choosing the right type of generator that suits your needs.


It’s not surprising for many experts to consider the use of solar energy as our future. In fact, we can no longer survive on conventional energy sources alone.

But we can’t also deny the fact that we still lack better literacy on solar energy. Factors like huge cost, less efficiency, and high labor have been the reasons we hesitated to accept solar generators.

Remember that when talking about generating energy outdoors, solar energy is our best option.

We hope the list above will help you determine the best solar generator according to your requirements and budget.

Just keep in mind that no device is perfect and the more powerful the item is, the more costly it can be. If you feel that we missed any product that should have been on the list, feel free to notify us.
