Cover image saying "Do Solar Generators Really Work?"

Let’s face it. This is one question on the mind of individuals who have been seriously considering the adoption of solar generators in solving their electricity needs.

Taking a look at what the electricity situation was like back in a hundred years ago, it is a different story from what we have today. Back then, electricity was a luxury.

Even up to the 1930s, only 43% of American homes were even connected to the electrical grid. It is spectacular to see how power supply has transitioned from being a luxury then to a basic need today.

The quest for a safer, better, and more environmentally friendly power source gave rise to solar energy options, one of which is the solar generator. Since it became available to the populace for use, it has enjoyed an unprecedented level of acceptance for several reasons.

However, if you are worried because you don’t know exactly how effective it is, you need to understand its working principle from the basics. So that takes us to the question: How does a solar generator work?

Solar Generators: How Do They Work?

The idea behind a solar generator is quite simple. In fact, it is way more straightforward than the working principle behind any other known form of energy around.

Basically, solar generators make use of solar panels to trap photons from the sun and charge a battery in the generator. The trapped energy is in raw form and cannot be used. Therefore, it goes into an inverter that changes it from direct current to alternating current, making it usable for most appliances.

Basically, the inverter steps up the generator voltage rating from 12, 24, or 48 volts to the appliance voltage rating of 110 or 240 volts. Hence, the power is stored in the battery of the solar generator for usage at any time needed.

Solar generators are manufactured by several brands worldwide. Each of these brands makes sure to produce various models of solar generators.

These models have unique specifications and selling points designed to appeal to the needs of a targeted set of consumers. That is why solar generators vary in kilowatts, portability, durability, and all other qualities and components.

How Much Energy Can a Solar Energy Generator Supply?

The amount of energy provided depends on each device. Generally, solar generators sell at a storage capacity between 0.1 and 2 kWh. Therefore, a single solar power generator should not be expected to power large-scale systems.

What Is Generally the Powering Capacity of Solar Generators?

Taking a look at the design structure of a solar generator, it is easy to see that it was explicitly designed to take care of home appliances. Its usage also covers a reasonable number of industrial appliances depending on the generator’s capability and the power demand of the appliance.

Low power–consuming gadgets such as smartphones, tablets, and GPS can be powered fully several hundred times through solar energy. More power-consuming home appliances, such as a refrigerator, furnace/space heater, or AC unit, can run on a solar generator for a much shorter amount of time.

When it involves industrial equipment, there is a need to operate them with high-capacity solar generators.

Usually, they demand a great deal of power supply, and as you would expect, the number of hours of operation will definitely be lower than that of home appliances. More powerful equipment such as construction devices can only operate at low power through a solar power generator.

Qualities of Top Solar Generators

Definitely, all solar generators are not of the same grade and capacity. However, most of the top solar generators available in the solar generator market have a few things in common.

These give them an edge over the others, and they usually revolve around the subject of affordability. Others focus on efficiency.

  1. Sophistication Level: The first quality is the sophistication level. Fundamentally, complex technology is needed to drive top-notch generators. Their complexity makes for their efficiency; these generators are also easy to assemble. Manufacturers should provide a detailed manual of device assembly. A specification of each component should be included as well.
  2. Portability: The weight of a solar power generator matters a lot. Usually, solar generator needs exceeded usage within the house, especially for UV owners. There might be an outdoor event in which you will need to power a few devices to ensure that it runs smoothly. Lighter generators are quite preferable in this scenario as they are way more comfortable to carry around. However, most portable generators store less energy for usage—this one aspect that solar generator producers are still working around to find a solution.
  3. Inverter Grade: the inverter is a crucial component of a solar generator. It is responsible for converting crude photons of direct current to alternating current, making it ready for usage. Usually, a higher alternator wattage grade to rating is not always good for you. Every gadget you intend to power often has a maximum electrical threshold. Apart from converting direct current to alternating current, an inverter with the right grade or rating will stabilize the current being supplied to your gadgets.
  4. Battery Capacity: this is a significant determinant of how much energy your solar generator can store for usage. A lower-rated battery capacity solar generator will quickly run out of power supply. On the other hand, higher-rated battery capacity is ideal as it serves you longer and increases the chances of it being compatible with high wattage devices. Also, a good-quality battery prevents excessive charge (from the solar panel) from damaging the generator.

Categories of Solar Generators

Think of all the appliances that you know will need a power supply in your house. From your television to the refrigerator down to indoor lighting, all these are powered by a solar generator.

However, these solar generators are in several categories, and your needs will determine the type of solar generator you would want to acquire.

Backup Solar Generators

A combination of backup generators may be used with farm solar panels or near a power station system since the conventional electricity might not be available in such areas.

These generators are known to have the highest of alternator wattage rating to enhance their functionality. Most solar backup generators are designed to be used in an emergency during a power outage.

While the idea of a backup solar generator is not a bad idea, the main disadvantage of solar backup generators is that they are very heavy and can be difficult to move around.

Another downside of this category of the generator is the fact that they are quite expensive to purchase. That being said, individuals who can cope with these disadvantages can decide to adopt it for their usage.

Portable Solar Generators

As the name implies, these are generators that are quite small in size and weight. Much has been said about this solar generator type already. As you already know, the batteries are quite low in rating.

However, they are your best bet if all you wish to power are small appliances such as laptops, cameras, and the likes. Most of the time, a portable solar generator may come with a strap like a suitcase, making it easy for you to move it around.

Smart Solar Box

This type is not as common. Basically, it is a small solar generator with an automatic design. The automatic feature is made evident in the fact that it regulates energy according to its condition. It is designed from other components such as a car battery and a simple exterior to keep the battery safe.

Now, let’s take a look at some solar generator models and what they have to offer.

Goal Zero Yeti 200X Portable Power Station Review

Front side of Yeti 200X

With just a quick inspection of the Goal Zero Yeti 200X, a powerful little beast that can keep all your devices topped off, you are going to take note of a few things.

First, it is relatively compact compared to similar devices. Although you can’t exactly refer to it as pocket-sized, it is quite small, and you can refer to it as a micro-solar generator. To this end, it won’t take up much space in your vehicle if you decide to take it with you on a camping trip.

When it comes to its charging prowess, the Yeti 200X is not doing so badly for a solar generator of its caliber. It is equipped with a total capacity of 37,400mAh.

However, the casing of the solar generator also contains other essentials such as ports and wiring connections.

If you are looking for the easiest way to get this charged, it is via a wall outlet. You can charge the 200X fully in about 4 hours or thereabout when you use this method.

Another way to get this solar power kit charged up is through your vehicle’s cigarette lighter outlet. Charging through this outlet also takes about four hours.

Ultimately, you can also power the Yeti 200X via a solar panel. It tends to charge faster with this option depending on the solar panel’s capacity connected to it.

Like other solar generators, you need to ensure that it is maintained, especially when you don’t use it over time. This is because it is made from lithium batteries, and it will naturally lose its charge when they’re not in use. Due to this, the most reliable way to store it is to simply leave it plugged in even when it is not in use. 

Temperature matters a lot when it comes to the usage of solar generators. For the Yeti 200X, it is designed to function well between 32 and 104 degrees Fahrenheit.

That said, users are warned against using it in extremely cold conditions. If you must use it in an extremely cold environment, you might want to keep it in a small styrofoam cooler placed in a protected space. Once you do this, the normal operation’s heat will quickly warm up the cooler and, by extension, the unit.
