For anyone looking to harness the clean, renewable energy of the sun, a portable solar generator is a great option. In order to use this power source, however, you will need portable solar panels to charge your power station. Our review will explain the different types of solar panels to pair with the best solar generators and recommend the top brands to purchase.


What is a Solar Panel?

At its most basic, a solar panel is simply a device that absorbs the rays of the sun and turns that energy into usable electricity. Most residential and portable solar panels work using photovoltaic solar cells made of silicon that send that energy through an MPPT charge controller to be stored in lithium-ion batteries or lead-acid batteries. An inverter can take the solar energy stored in the battery and transform them into electrical current, which you can use to power devices, run appliances, or even keep an air conditioner running.

Not all solar panels are created equal, however, and consumers are encouraged to do their homework. In this article, we'll outline some of the best solar panels available today, particularly for use with portable solar generators for outdoor activities or emergency power.

How We Reviewed Solar Panels

Before we get into specific recommendations, it's important to understand some of the factors that cause one solar panel to stand out from the next. Here are just a few of the criteria we used to assess the best solar panels for use with portable solar generators.

Type of Solar Panel

Solar panels come in three basic types: monocrystalline; polycrystalline; and thin film.

  • Monocrystalline solar panels tend to be sleek and highly efficient, but they are also the most expensive.
  • Polycrystalline panels, on the other hand, are a little bulkier and less efficient, but can be obtained for a lower price point.
  • Thin film solar panels are the cheapest of the bunch, but also the least efficient. And, they require the most space.

As you consider purchasing solar panels, knowing what type you want is one of the first things you'll need to think about.

Portability

If you plan to use your solar panel with a portable generator, then you'll naturally want something that you can transport with relative ease. Note that solar panels can vary greatly in their size and weight. Some are so small that they can be folded into briefcases, which is obviously a boon for those seeking portability for an off-grid power supply.

Power Output

Another crucial factor is power output. Different panels can produce varying amounts of energy, or wattage, which can, in turn, determine things like how many devices you can charge at one time, how long your solar generator will last between charges, and how quickly you can recharge your solar power generator.

Conversion Efficiency

The conversion efficiency rating tells you how much of the sunlight that hits the solar panel is actually converted into usable energy. This number is always given as a percentage. So, for example, if you have a solar panel with an efficiency rating of 20 percent, it means that about 20 percent of the sunlight that hits the surface will ultimately be turned into energy that you can use. Typically, any panel with a conversion efficiency over 20% is considered high-efficiency.

Charge Controller

Some solar panels include a built-in charge controller. A charge controller, or charge regulator, helps to moderate the voltage/current of your solar system. Basically, the charge controller is what prevents your battery from overcharging. This is an important part of any solar system, as it helps extend the battery life of your system and prevent accidents. Look for systems that use MPPT charge controllers.

Expandability

When you first start getting into solar power, you may not know exactly how many panels you need. That's what makes expandability such an important concern. Expandability tells you how easy it will be to add more panels to your solar configuration, especially with modular systems that can easily connect more panels.

Price

Naturally, your budget is going to be a major consideration as you look for a new solar panel. Solar panels can vary in their price point, but it's not enough to look for the cheapest model. Make sure you're getting the best overall value, paying a reasonable price for a solar panel that will help you achieve your clean energy goals.

The Benefits of Portable Solar Panels

Portable solar panels offer a range of benefits.

  • Solar panels can be paired with portable solar generators to provide you with emergency backup power in case of a power outage. Unlike gas generators, these are quiet and environmentally-friendly. Plus you will never have to purchase fossil fuels to run them as a backup generator.
  • Portable solar panels can be ideal for living "off the grid," or for extended camping or RV excursions. With a good generator and the right types of solar panels, you can enjoy plenty of electrical power for cell phones and small appliances even when you're outside and far from any power outlets.

These are just a few reasons why switching to portable solar power can be beneficial, though again, you'll want to ensure you select the right solar panels to meet your goals.

Solar Chargers vs. Portable Solar Panels vs. Rigid Solar Panels

We already elaborated on some of the key differences between monocrystalline, polycrystalline, and thin film solar panels. Now, let's turn our attention to another important area of distinction: solar chargers, portable solar panels, and rigid solar panels.

A solar charger is a small device that uses sunlight to generate electricity. These are usually used to power smaller devices, like phones or tablets, or anything you would plug in to a car charger.

Portable solar panels, like the ones we mentioned above, help absorb and capture sunlight, which you can use to power a portable generator or battery bank. These are ideally suited for camping or for an off-grid lifestyle. They can offer the same amount of energy that you get from an AC outlet.

Rigid solar panels are designed for rooftop installation to provide power to homes and buildings. Generally, these provide the most energy when connected to high-capacity battery storage.

Types of Solar Inverters

The inverter is an important component of any solar panel system because it's the component that actually takes stored solar energy as DC power and turns it into more usable AC power. There are two primary types of solar inverters used for portable solar generators.

  • Pure sine wave inverters are designed to produce smooth, reliable, and quiet electric AC currents and work best at providing continuous power to delicate or sensitive electronic devices.
  • Modified sine wave inverter provide a bit choppier and nosier current and are primarily meant for simple devices and appliances.

Knowing your inverter types is another important way to make an informed decision about your solar panel and solar generator purchase.

What Devices and Appliances Can You Charge With Solar Panels?

As you contemplate your solar energy needs, it's important to think about the specific devices and appliances for which you need power.

Some portable solar panel options come with 12-volt and USB ports that allow you to directly connect and charge certain devices. These can include things like smartphones, tablets, and computers. Alternatively, you can connect your panels to a generator or battery to power certain appliances that you would plug into a wall outlet like a mini-fridge, CPAP machine, or coffee maker. The specific devices you can power with energy from solar panels will depend on your system's output, run time, and battery capacity, typically measured in watt-hours.

We recommend using an online calculator to tell you roughly how much energy you'll need from your solar panel. Try this calculator to see what types of devices you can use.

Choosing the Best Solar Panels

The right portable solar panels can completely change your relationship to renewable energy. In addition to serving as a clean energy emergency backup in case of a blackout, they can also empower you to enjoy the adventurous lifestyle you crave.

As you seek the best portable solar panels, make sure you weigh all the important factors, from power output to price point. Use this guide to start your search, but also be sure to carefully assess each product according to your own energy needs.
