Buying a new product--especially an expensive one--isn’t just a simple decision. Smart consumers research the market by looking at positive (and negative) reviews online, consulting friends, reading case studies, and examining the quality and source of the product’s components. Understanding the build of a product and educating yourself on the reputation of a brand isn’t always an easy task. However, most of this information can be accessed through the web, so the process to educate yourself is easier than it’s ever been. But what if I were to ask you about the components and company reputations for commercial solar lights? That isn’t as easy as logging onto a review site and checking for a review score, so we’ve prepared a guide to help you look for what sells and what stinks when it comes to solar lighting.

Just like us, you want the best bang for your buck. Here’s what to look for when it comes to quality, service, warranty, and other aspects that may be a concern for people switching to solar lighting over traditional.
One of the most important components for a solar light is--well, you guessed it, the solar panel itself. When you’re searching for quality panels on your lights, you’ll want to check a few boxes and ensure your panels have these key build factors.
You’ll want to purchase a panel build of what’s called monocrystalline silicon. The biggest difference between these panels and others is that they’re made of a single ingot of 99.9% pure silicon, so the efficiency of the panels is higher than other (commercially available) panels on the market.
Elmer’s glue might have a fantastic application for in-house projects, but it has no place in photovoltaic builds. What you need is a heat-activated, electrically-conductive bonding solution. Remember, these are solar panels and they’ll be sitting in direct sunlight for years. If you want to ensure your panels will stay functional through constant temperature fluctuations, check that your solar light manufacturer has a great adhesive for the panels. Otherwise, the silicon wafers may lose their effectiveness.
Another concern about solar lighting that you need to consider is the temperature coefficient for a panel. Some areas that receive a lot of sun hours are also notoriously hot, and so a strong TC would be -0.3% to -0.5 percent. A solar panel with -0.3% means for every degree in Celsius the panel’s temperature increases above 25 degrees, the panel’s efficiency decreases by .03%. Anything above .5 is a sign of a low-quality panel.
Glass for a monocrystalline photovoltaic panel needs to be tempered glass. The difference is that it can be anti-reflective and also shatter-proof in the rare but entirely possible situation of something severely damaging the solar light. It’s another concern for solar lighting that is commonly looked-over since it’s a misconception that any glass will work fine for the panels. The certificates of IEC (IEC, IEC) and UL for your solar panel mean that their glass meets the industry standard.
Solar energy is important, but if the light fixture on your solar investment doesn’t work well--or at all--your light might as well be a wonderful street decoration. Here’s what you want and don’t want in a light fixture.
LED light fixtures are known for being incredibly efficient. These lights are best for solar energy since their luminous efficacy (lumen output per watt consumed) is about 60 lumens per watt. To easily compare, an incandescent bulb is about 15 lumens per watt--not that any proper manufacturer would use an incandescent bulb on an outdoor light (we’d hope), but ensure LEDs are used for your solar light to ensure the best lumen output for the power available.
Heat is a huge concern for solar lighting. A proper light fixture needs a sufficient heatsink to draw heat away from the bulbs to dissipate into the air. For LED fixtures, the heat is a by-product of the semiconductor within the bulb that produces the light. It’s important to check the material and shape of the heatsink to determine if it’s sufficient for keeping the junction temperature of the LED bulbs down. Copper is the best material for heat conduction—however, it tends to be very expensive so aluminum is used to keep costs down. Ensure the finish and conductive adhesive are quality too so your investment will last a long time.
Check what’s holding your fixture together. If the construction components are screws that are easily removed or parts that require a little force to disengage their locking mechanisms, then go in search of a higher-quality fixture. Remember, your biggest concern with your solar light is you want it to last in all sorts of temperatures and weather conditions. Cheap glue and screws to easily remove is a telltale sign of a short-lived investment.
There are plenty of electrical components “under the hood” of a solar light, and so it’s best to check and make sure your investment doesn’t use cheap-quality parts. Here are a few components that you’ll want to have a high concern with on your solar light.
These components generally serve two functions—they manage the flow of electricity from the battery to the fixture and instruct the light fixture when to turn on and off. A bad controller can shorten the lifespan of your battery or light fixture, so if either (or both) the fixture and battery have problems, be sure to consider that it could be your controller.
A lot of controllers have full light system customization options and are protected with rugged materials so they can survive temperature changes.
A solar light driver is another major concern for solar lighting. They regulate the flow of electricity to the battery and light fixture. A poor-quality driver won’t be able to dissipate heat very well—drivers are under frequent electrical load, so if a driver feels like it’s made of material that won’t last, that’s likely the case.
As a general rule, the solar lighting company you decide on should provide a range of warranties, either full or limited. Some of the best warranties on the market will provide full coverage for 10 years which covers every component as long as the functionality of the component isn’t drained from regular use, improper installation, or damage.
If there aren’t a range of warranties, or the warranties last a very short time (only a year for example), there’s a large reason for this. Don’t buy from that company.
Portable solar panels are a great investment for anyone who enjoys spending time outdoors. They are an eco-friendly and efficient way to charge your devices without relying on a power outlet from home.
However, before purchasing, you should consider a few things, such as how much power you need, what size panel you need, and what company has the best return policy.
By asking yourself the following questions before buying a portable solar panel, you can be sure that you are making the best decision for your needs.
The power output of a solar panel is an important consideration when determining which solar panel to buy. The power output is measured in watts, indicating how much electricity the solar panel can produce. Solar panels with a higher wattage will produce more electricity, making them a better choice for larger homes or businesses.
However, solar panels with lower wattage are more affordable and can still provide enough power for smaller homes or RVs. To find out the power output of a particular solar panel, consult the manufacturer's specifications. Once you know the power output you need, you can narrow your choices and choose the best portable solar panel.
When shopping for portable solar panels, one of the most important questions to ask is about the portable solar panel efficiency rating. The efficiency rating tells you how much of the sun's energy the panel can convert into usable electricity. The higher the rating, the more efficient the panel. However, when choosing a panel, efficiency isn't the only factor to consider. You also need to consider how much power you need and where you'll use the panel.
For example, if you need a lot of power for camping or RVs, you'll want to choose a high-wattage panel with a high-efficiency rating. But if you're just looking for a small panel to use around the house, you can get away with a lower wattage and lower efficiency.

Portable solar panels are a great way to reduce your carbon footprint and save money on your energy bill. However, before you purchase portable solar panels, it is important to ask how long they are expected to last. Some solar panels have a lifespan of only a few years, while others can last up to 20 years or more. The type of panel you purchase will ultimately dictate how long it will last.
Monocrystalline silicon panels are the most expensive but also the longest lasting, with an average lifespan of 20-25 years. Polycrystalline silicon panels are less expensive but have a shorter lifespan of 10-15 years. Thin-film solar panels are the least expensive option but also have the shortest lifespan of only 5-10 years. Ultimately, the decision of which type of panel to purchase depends on your budget and your needs.
When you're looking at different portable solar panels, it's important to ask what the bend angle is. This is because the bend angle will determine how much sunlight the panel can capture. If you're using the panels in an area with little sunlight, you'll want to ensure that the bend angle is large enough to capture as much sunlight as possible.
On the other hand, if you're using the panels in an area with a lot of suns, you can get away with a smaller bend angle. The bottom line is that the bend angle is an important factor to consider when you're choosing portable solar panels.
Before you buy portable solar panels, you also need to consider their dimensions and weight. This is important to know because you need to ensure the panels will fit in the space you have available and that you can easily carry them with you if necessary. Most portable solar panels are lightweight, but some can be bulky. So, it's important to consider both the size and weight of the panels when making your purchase.
Additionally, you'll want to consider how many devices you'll be powering with the solar panels. A smaller panel should suffice if you only need to charge a or small laptop. But if you're looking to power larger items like a fridge or tv, then you'll need a bigger panel. Ultimately, the size and weight of the solar panel will be dictated by your specific needs. So, make sure to ask this question before making your purchase.
If you're considering purchasing portable solar panels, be sure to ask the retailer about the portable solar panel warranty. Many solar panel manufacturers offer warranties of 10 or 20 years, but some only offer 5-year warranties. The warranty length is important because it will give you an idea of how long the panels are expected to last. Generally, the longer the warranty, the more confidence the manufacturer has in their product.
However, it's also important to read the warranty's fine print to understand what is and is not covered. Some warranties only cover defects in materials, while others may also cover damage caused by natural disasters. By understanding the terms of the warranty, you can be sure that you're getting a quality product that will provide years of trouble-free service.
If you're looking for a portable solar panel to take on your next camping trip, make sure to ask if it's waterproof before making your purchase. While most solar panels are designed to withstand occasional exposure to water, they're not all created equal. Some panels are only waterproof in light rain, while others can withstand being submerged in water.
Knowing how your panel will perform in wet conditions is essential for ensuring that you can rely on it when you need it most. Waterproof panels are also a good choice if you live in an area that experiences high humidity or frequent precipitation. By choosing a panel built to withstand the elements, you can be sure it will be there when you need it.
When you're shopping for portable solar panels, it's important to ask questions about the construction materials. Some panels are made with lower-quality materials that aren't as durable or efficient. Others use top-of-the-line materials that are built to last. By asking questions, you can ensure you're getting a panel made with high-quality materials that will perform well for years to come.
Some things to ask about include the type of solar cells used, the frame material, and the glass. Solar cells come in different types, and some are more efficient than others. The frame material affects the durability and weight of the panel. And the type of glass used can affect the panel's efficiency. By asking these questions, you can ensure you're getting a portable solar panel made with high-quality materials that will perform well for years to come.
With the advent of technology, solar panels have become increasingly portable, making them a great option for those who want to reduce their carbon footprint while still being able to take their solar power with them when they travel. However, before purchasing portable solar panels, it is important to ask about the included portability features.
Some portable solar panels come with fold-up legs that make them easy to transport, while others come with carrying cases. Some portable solar panels also come with built-in inverters, making them even more convenient for those who want to use them on the go. By asking about the portability features that are included with a particular model of portable solar panel, you can be sure that you are getting the most bang for your buck.
The main advantage of portable solar panels is that they allow you to generate your own electricity, even when you're not near a power source. However, it's important to consider a panel's battery storage capabilities before making a purchase. Some panels come with built-in batteries, while others require purchasing a separate battery pack. The size of the battery will determine how long the panel can run without sunlight, so it's important to choose a panel that can store enough power to meet your needs.
For example, if you plan on using the panel to recharge your while camping, you'll need a panel with a large battery that can store enough power to keep your charged for several days. On the other hand, if you only need the panel for short-term use, such as during a power outage, you can choose a panel with a smaller battery. In any case, it's important to consider battery storage when choosing a portable solar panel.
Before purchasing portable solar panels, it is important to determine which devices they are compatible with. There are a variety of portable solar panels on the market, and each one is designed to work with specific types of devices. Some panels are compatible with laptops, while others are designed for cell phones or handheld electronic devices.
Still, others are meant to be used with larger pieces of equipment, such as RVs or boats. By knowing which devices you need to power, you can narrow down your options and find the right panel for your needs.
Additionally, it is important to ensure that the panel you select is compatible with the types of batteries that you intend to use. Otherwise, you may find yourself stuck with a panel that cannot provide power when you need it most. By asking about compatibility before making your purchase, you can ensure that you select the best portable solar panel for your needs.
Another important consideration when shopping for portable solar panels is whether they come with a built-in battery. This is especially important if you plan on using the panels in an area where there is no electricity. Many people assume that all portable solar panels come with batteries, but this is not always the case. Some models require that you purchase a separate battery, which can add to the cost of the panel.
In addition, it is important to ensure that the battery is compatible with the panel. Otherwise, you may not be able to use the panel in an emergency situation. By asking if the solar panel comes with a built-in battery, you can be sure that you are getting a product that will meet your needs.
