Electricity is an awesome discovery and a truly helpful technology. It makes life so much easier. However, this power doesn’t always come cheap. In fact, electricity bills are increasing with market inflation, and it can be a headache, especially if you have numerous appliances at home or if your business involves regular usage of electricity.

Of course, most of us rely on grid-based energy to power our electrical devices. What people aren’t paying attention to is the fact that most grids harness power from fossil fuels, a source that’s non-renewable. Therefore, at some point in the future, we will run out of this source, and we will have to produce energy through other sources.

Luckily, the use of solar generators is becoming more and more common. There’s an increase in the number of people relying on solar energy to power up, and not just residential infrastructures, but also large buildings. It won’t be surprising if, in the future, the planet will rely on the sun’s power for energy. This technology is expected to reach greater heights, whether it be in energy production or convenience of use.

The use of solar devices is a big step towards a more sustainable future. Since these devices have an unlimited energy source, it provides financial and environmental gains. This article will explain what a solar powered generator is, how it works, and what its pros and cons are.

It will also provide you with tips on how you can choose the best machine for your needs. This piece will also enumerate five of the best brands out there

What is a Solar Generator?

A solar-powered generator is a device that serves as an alternative to grid-connected energy. It is used to supply energy to power electrical devices when electric outlets are non-operational, possibly due to outages. It is also used for areas without a stable grid connection due to location, such as mountain-based communities or islands.

Solar generators combine solar cells with a storage device, such as a machine, so it can reserve energy for consumption when needed. The sun is used for the charging process, so the device can be used multiple times and recharged when the current stored energy is depleted.

Solar generator machines are often built portable to enable mobility and ease of use. This device can be useful for trips as well, such as yacht cruises or RV road trips, because they can provide power to the appliances in the vehicle even in remote areas.

Aside from the panels and power cells, some generators also have a charge controller, which allows monitoring of the charge level of the battery and prevents overcharging to prolong the battery’s lifespan.

Some also add an inverter to the picture to convert the direct current to alternating current and make it compatible with most electrical devices. Because of the portability and capacity to store energy, the sun-powered generator is considered an eco-friendlier alternative to diesel or petrol-powered ones. However, how does this machine work?

How Solar Generators Work

What’s the mechanism of a solar powered generator and how does it power up devices without needing to be plugged in? The process requires light, electrical, and chemical energy. The solar panels are the primary receiver of photons from the sun in the form of light. The photons received are converted from solar to electrical energy through generating current.

This energy is then stored in the power cell or battery (mostly lithium-ion ones) and is now converted into chemical energy. That chemical energy can be accessed to generate electricity to power up electrical devices such as electric fans or heaters. Solar systems generate direct current.

Therefore, an inverter may be required to convert that direct current to alternating current and make it usable for AC-compatible electrical devices to work.

If the solar power generator is exposed to the sun for too long, it is possible for it to absorb more than sufficient energy to charge the system’s battery and exceed the storage device’s capacity.

This is where the role of the charge controller comes in. It regulates the charge flow so the battery won’t overcharge or overheat. With the storage capacity and ease of use, it is perfect for on-the-go use.

Things to Consider Before Buying Solar Generators

 With so many brands out there, finding the one for you can be a tricky job. Now that you understand how these devices work, how do you choose the best one for your use? There are various aspects you need to look for so that you can make the right choice.

  • Size – When it comes to determining the device size for you, it is vital to think about where you would put it and what you would use it for. If you have minimum storage, you’d want a smaller device. Of course, bigger devices often have bigger capacities, so you want to consider that if you have enough space.
  • Weight – The weight of the device is of great importance, especially if you plan to use the device for trips. Bigger devices hinder mobility. However, heavier devices have better capacity as well. Therefore, if you’d like more capacity and won’t need to move your generator around, you can settle for bigger, more powerful portable solar generator
  • Battery – There are different cell types, but the most commonly used for sun-powered generators are lead-acid and lithium-ion ones. The former is more economically priced, but the latter has more capacity and can be more efficient for long-term use. It helps to have high-capacity batteries, especially when the summer ends, so you can use the generator even during winter.
  • Dimensions – The length and width of the solar panels will determine the amount of sunlight that the device can absorb, so it is best to have a device that has maximum exposure so it can charge your batteries faster.
  • Watts – The watt ratings of the device plays a large role in its effectiveness as a portable device. Specifically, it refers to continuous or surge watts. To determine the continuous watts you’d need, you need to sum up the watts per hour of your devices combined and multiply that sum with your daily consumption hours. Surge watts are the sudden increase in consumption needed to turn on a device. Your generator should handle both the continuous and surge watts without leading to an outage.
  • Charge controllers – Since the regulation of currents coming into your batteries is important for the longevity of the device, it is good to look for charge controllers that not only cut the connection between the power cell and the panels when a certain voltage is attained but also have a three-stage, maximum power point tracking (MPPT) flow management. It also pays to have a waterproof charge controller so you won’t have to worry about rusting.
  • Unique features – Other unique features you may want to look for in your sun-powered device include certifications of safety and excellence, multiple alternating-current outlets to cater to several devices at once, USB ports, and LED panels for charge and current monitoring. You also want to look for framed panels for increased protection and convenient positioning.
