Short on Time? Here&#;s The Article Summary

A 15-watt solar panel is versatile and portable, capable of charging various 12V batteries like those in cars, boats, RVs, and more. It generates around 1 amp per hour in sunlight, maintaining battery health and extending lifespan. It can power small devices like electric fences, deer feeders, and through built-in USB outputs, smartphones, and tablets. The Lion Energy GO panel is highlighted for its portability, weighing only 4 pounds, with a maximum output of 8 amps and dual USB connectors.

For larger needs, a 400-watt panel can power appliances like dehumidifiers and vacuums, suitable for off-grid projects. A 100-watt panel can run small devices and, with a battery, store excess energy for later use. Smaller panels, like 50W and 45W, charge 12V batteries and can power devices like USB fans, smartphones, fish finders, and lawnmowers. Each panel size serves different applications, from small, portable uses to more extensive, off-grid setups.

Introduction

Solar panels come in handy, whether they&#;re big or small. This is one of the things that makes them so viable when you&#;re in the outdoors or looking for something to power a few appliances.

While a 15W solar panel is not the largest of panels, we think you&#;ll be pleasantly surprised by what it can still do while also being small and portable to go just about everywhere.

Batteries

A 15-watt solar panel isn&#;t the biggest panel you can get, and it&#;s not the smallest either. It&#;s a solar panel that does the best it can. 

In sunlight, it can generate around 1 amp every hour. This means that the solar panel can keep certain batteries charged like those on a boat, quad-bike, tractor, car, and RV. 

A solar panel of this size can also be used to power an electric fence or a deer feeder. 

Charging batteries means that you&#;ll need to purchase a few extra things like a 12V car adapter, some wire, and battery clamps. Keep an eye out for a 15W solar panel that includes these as part of a kit, it&#;s more convenient that way.

The 15W solar panel helps to maintain the battery, making sure that it lasts as long as it can. That leaves you with a battery that stays in peak condition while being used for various applications.

When it&#;s not a car or boat battery that you need to charge, the LifePo4 battery is another convenient piece of equipment that can be used to provide power to larger appliances. Since this is also a 12V battery, the 15-watt solar panel can be used to charge it. 

To prevent overcharging and discharging you&#;ll need to use a charge controller. This is necessary for a 15W solar panel. 

Lion Energy GO Watt Solar Panel - a Review

The Lion Energy GO is small and portable. It can power a 120Wh AC inverter and has built-in USB outputs to charge smaller devices like your smartphones or tablets.

Weighing only 4lbs, this solar panel makes for a highly maneuverable piece of equipment. It&#;s ideal for outdoor use anywhere you go. 

The Details

The solar panel is made with high-quality monocrystalline cells. It measures 18.4 × 14.3 × 1 inches.

It features a dual USB connector wire that&#;s 11.8 inches long and has a maximum power output of 8 amps. This feature is specially built to be compatible with another product from Lion Energy.

The panel is suitable for charging smaller devices, too, with two USB outputs. These are 5.34V each, with an output power of 4 amps.

The Verdict

A small solar panel provides enough power for your batteries, solar inverters, and smaller devices. It&#;s ideal for those looking to get away for the weekend while keeping a few luxuries running, and a few smartphones charged - just in case.

More Solar Panels

A 15-watt solar panel suits smaller needs and does it exceptionally well. 

But are they the only option for you? Of course not. Here are some more solar panels, each with its own power output and applications. 

400 Watt Solar Panels

A 400 Watt solar panel can supply enough power to a variety of appliances with full sunshine exposure.

Some of these appliances include but are not limited to a dehumidifier, rice cooker, vacuum, and slow cooker. A dehumidifier needs around 240A to operate while the vacuum needs 200A. 

A solar panel this size can more than comfortably run these appliances when exposed to the ideal amount of sunshine.

These solar panels are best suited for off-grid projects and prolonged outdoor trips where electricity is scarce. Measuring an average of 80×40 inches, these panels are best for mounting on the roof of your RV or home. 

100 Watt Solar Panels

A 100-watt solar panel can power quite a few devices. Even one solar panel can generate enough power to run several small devices like smartphones, ceiling fans, lamps, a WiFi router, and even laptops. 

This won&#;t be enough to power larger appliances like a TV, heater, or air conditioning unit. These appliances generally need more than 100 watts to operate.

Using a 100-watt solar panel in combination with a battery is a good way of storing energy that will otherwise be lost. Whatever energy the solar panel generates that isn&#;t immediately used can&#;t be stored otherwise, and a battery helps to save that energy for when you need it at night. 

These solar panels are compatible with either lead-acid batteries or lithium-ion batteries. 

50 Watt & 45 Watt Solar Panels

While these two aren&#;t as big as the 100W or 400W solar panels, they&#;re still useful. 

But what can a 50-watt solar panel power exactly? Well, it&#;s designed to charge batteries that run other appliances. The only prerequisite here is that the batteries should be 12V. This can include your car battery, the one for your boat, and even a tractor battery.

It won&#;t necessarily run an appliance directly but it can provide power to a small USB fan if the panel features a built-in USB port. This can also be used to charge smartphones, too.

So, while a 50-watt panel can provide power for these appliances, a 45-watt solar panel will run similar devices. Although it&#;s 5W smaller, a 45W panel can still be used to provide power for a fish finder, smartphone, GPS, a trolling motor, and even a lawnmower.

Find out How You Choose Your New Solar Panel

We've created the list below to serve as a guide to making a good purchase. You should always keep in mind that a solar panel system is a long-term investment, hence there are many aspects other than the price that you should take into account.

1. Solar Panel Cost

This is probably the first factor people consider when comparing solar panels. The solar panel cost is determined by different variables: the size (in Watts), the physical size, the brand, the quality of the materials, the durability (or warranty period) and any certifications the solar panel might have.

A key guide on how to choose a solar panel is to consider the cost. However, it shouldn&#;t be the one and only factor to be considered, since the least expensive panel might not be the most efficient and probably not the best option if you consider the long term. How to choose solar panels can be risky but, they have a long lifespan (more than 30 years), so it is more important to ensure a good quality system than choosing the cheapest option.

2. Solar Panel Quality

This takes into account how the panel is manufactured and the quality of the materials used to build the solar panel. There are different types of manufacturers producing panels that differ in quality, price, and efficiency. There are vertically integrated solar panel manufacturers which control each stage of the production process. They put a strong eye on quality and invest a lot into research and development (R&D). There are other manufacturers that only assemble panels, but usually don't manufacture their own cells and don&#;t invest in R&D. They use more human production than robotic, but produce the most affordable panels.

When choosing your solar panel supplier it is wise to check the companies&#; reviews or history and see what experiences clients had with each of them. Since you will make a big investment, it is important to do a bit of research and see if clients are satisfied with the product and the customer service, and if the company did all that it has promised.

3. Energy Efficiency

Solar panel efficiency is how much of the light the panel receives is converted into electrical energy and hence, how much power your system will generate. The more efficient, the better (and more expensive). It is not always the best choice to get the biggest and highest efficiency solar panel, since you might end up spending more money than you should to cover your energy needs.

You should assess your requirements and find the panel that best suits your needs: this means not underestimate, but also not to overestimate your needs. Likewise, you don&#;t need a Ferrari to take your children to school (you can have it of course, but you can do the same spending a lot less).

4. Temperature Coefficient

This refers to the impact that heat has on a solar panel&#;s operational efficiency after installation. Since solar panel overheating accelerates their ageing, the lower the percentage per degree Celsius, the better.

5. Durability

This could be an indicator of the manufacturer&#;s confidence in its products. Usually, solar panels have a 25 year warranty (as long as the company operates). If the manufacturer does not offer a long warranty period, you could suspect that their product is not very good and hence they don&#;t want to take any responsibility. In this case, be careful not to be mislead by a tempting price since you might regret it in the long term.

Of course, it is important to properly maintain your solar panels to increase the lifespan of them. Fortunately, they are easy to take care of and don't require much maintenance.

6. Size

This takes into account the physical size and the size in Watts. You should make sure to install a solar panel system that is big enough to power all your appliances, and also that you have the space required to install it. The physical size of the panel will vary depending on how powerful the system is (the more Watts, the bigger) and the type of solar cells used to build the panel.

An average household would typically require a 4kW solar system. Watts are related to the output of the panel (a 200 Watt panel will generate 200 Watt-hours each hour under ideal conditions while a 100 Watt panel will generate 100 Watt hours) and they are directly related to the price of the system.

The wattage of the solar panel is probably the most important thing you need to get right since underestimating the number will lead to a lack of energy, and overestimating the wattage will lead to spending more money than you actually need.

7. Types of Solar Cells Used

There are different types of solar panels with different efficiencies. Although their names might sound confusing, it is good to know at least the name not to be out-of-topic if your supplier happens to mention this.

Monocrystalline silicon offers high efficiency and good heat tolerance characteristics with a small footprint. Polycrystalline (or multi-crystalline) silicon cell based solar panels are now the most popular choice in residential installs. There are also Amorphous (or thin-film) silicon cells, which use the least amount of silicon and are not very efficient. For an equivalent wattage, a crystalline panel will be smaller than an amorphous panel.

Find the Right Solar Panel System for Your Home

Now you have the tools to choose the solar panel system that best suits your needs and be immersed in the world of solar energy. You should always compare different offers and see which supplier you find more convincing.
