With the increasing popularity of solar energy, there will be various options to choose from and expensive prices to pay. Nature Power has decided to enter the competition with their 120-watt portable briefcase solar panel. Before we get to the product, it is important to know who Nature Power is.
Nature Power is a United States brand that makes solar power products. These products include wind charge controllers, power inverters, and solar panels. They aim to provide high quality and reliable power alternatives to the market with competitive prices. Currently, they have offices located in the US, Mainland China, and Hong Kong. Nature Power’s focus is on renewable energy products that are easy to set up for consumers.
The power produced by these panels comes from sunlight exposure. When sunlight meets the panel, electrons of the solar cells are knocked loose. Using these loose electrons, an electrical current is created which then can be stored in batteries for use. It’s important to note here, however, solar panels alone do not store energy.
They produce the energy that will be used by you, the consumer. To store energy, it needs to be paired with an appropriate battery. The types of batteries you can use are 12V, lead-acid, deep cycle, gel-cell, and heavy-duty batteries.
Solar energy offers a clean and sustainable form of power. No hazardous waste is produced, or smelly gasoline is needed. Maintenance is easy, a simple rinse is all that is needed to maintain a panel.
Going back to the product, what exactly makes it stand out from its competitors? It is a monocrystalline solar panel. Monocrystalline is a material with the highest efficiency rating compared to other panels. This means more power production with less space required to produce it. What thisNature Power 120-watt briefcase solar panel features:
- A pop-out mount (great for an easy setup to maintain an optimal angle for collection)
- Aluminum frame (makes this panel as sturdy as one can get, it is still advisable to avoid constant hits to it)
- Built-in diode (preventing discharge is a must for those who enjoying camping)
- Solar Charge Controller (makes charging batteries simpler and prevents overcharging)
Things to Consider Before Buying Solar Panels
If you have considered using solar, you must read up on all the information to learn what you should look for when purchasing solar panels. You should not dive in headfirst and trust every brand. Going in with a little knowledge can go a long way.
What makes going solar difficult for most, is the varying technologies, quality, and the market. If you had gone in headfirst without any knowledge you might have bought a solar panel system that does not produce enough energy. Or you might have bought a solar panel system that does everything you need but will constantly require repairs and maintenance due to its questionable quality. This can cost you a lot of money in the long run.
To begin our process, you must first know how solar panels work. Using the solar process means relying on the sunlight to hit the solar panel. This separates protons from electrons, and it is then sent to an inverter. The job of the inverter is to convert the DC electricity into AC electricity. Once it is converted, it can power your home. With this in mind, the equipment needed for your solar panel system is photovoltaic solar panels, an inverter, a racking system to mount the panels, and wiring to connect them all.
1. Solar Panel Output
Using your power bill, you can break down the amount of electricity you use on a 24-hour basis. This will help you determine how many watts your solar panel must produce. Solar panels operate efficiently when the sun is highest in the sky.
Weather should also be taken into consideration as those in climates that have the sun covered most of the time will give your panel some difficulty. Cold weather, however, helps solar panels work more efficiently. It allows the panel to produce more voltage which can then be used by you.
In terms of cloudiness, a partly cloudy day can drop electricity production by an estimated 10 to 25%. For days where it is mostly cloudy, solar panels will produce an estimated 10 to 30% of electricity produced on a sunny day. Don’t let this scare you as going solar is still a good investment.
2. Types of Solar Panels
Solar panels can be fit into one of these three types:
1. Polycrystalline & Monocrystalline
These two solar panels are composed of silicon structures. These structures are then arranged into columns and rows to form a rectangular panels. The manufacturers then cover the solar panel with a glass sheet. Lastly, the manufacturer cover the solar panels in a metallic frame. These two products however, differ in terms of performance and what they are built from. The solar cells from monocrystalline panels are a product of single pure silicon crystal. Meanwhile for polycrystalline solar panels, the manufacturer first liquefy the silicon crystals and then use the liquid to make solar cells. Monocrystalline panels appear black because of the way light interacts with silicon. Polycrystalline panels appear blue because of the way light reflects on the crystals.
Monocrystalline panels appear black because of the way light interacts with silicon. Polycrystalline panels appear blue because of the way light reflects on the crystals.
Thin-film solar panels are made from several different materials. Three materials can be made from, copper indium gallium selenide, amorphous silicon, and cadmium telluride. The main material is placed between thin sheets of conductive material which is then covered with a layer of glass for protection. Depending on what material it is composed of, it can look black or blue. These types of panels can be identified by how thin they are compared to monocrystalline and polycrystalline.
3. Maximum Power
When it comes to power, monocrystalline panels have the highest power capacity and efficiencies. It offers an efficiency of 15-20%. Polycrystalline panels offer efficiencies under 15%. Monocrystalline panels come in higher wattage versions with more than 300W in power capacity. On the other hand, some can even exceed 400 watts. Polycrystalline panels offer fewer wattage capabilities ranging from 240 up to over 300 watts.
This leads us to thin-film panels which offer the lowest of the three in terms of capabilities. It needs more space to produce the amount of wattage the other two do. It offers efficiencies in the 10 up to 13 percent range. Lower efficiency means more panels are needed to match the power produced from polycrystalline or monocrystalline panels.
Your needs will determine the amount you should consider spending when looking for solar panels. Since monocrystalline panels are the most efficient and expensive type, these should be considered only for those with limited space and who need maximum efficiency.
If you have more space, then your options should come down to polycrystalline and thin-film panels. Polycrystalline panels were produced to make solar panels more affordable, but this gap is slowly closing in.
If a ton of space is available but a lightweight solar panel is not a priority, then consider thin-film solar panels. Since they are the cheapest, lightest, and cover more ground than the other two mentioned.
5. Size and Weight
Sizing and weight are also an important consideration when looking for a solar panel system. Some panels can be too large or too heavy to be supported on a rooftop. Generally, you should consider a roof inspection to help you determine the size and weight your roof can support. Panel weight varies from brand to brand, but in general, it hovers around the 33-50-pound range.
In terms of size, they can reach up to dimensions of 65 inches by 39 inches. Depending on your needs, panels can weigh up to 800 pounds alone. To prevent any accidents or roof collapses, you should find out how many pounds per square foot your roof can handle.
However, if you are looking for solar panels to travel with then the weight and size should be as low as it can get.
When it comes to purchasing solar panels, the warranty is one of the most important issues that should be in your consideration. Since you can’t guarantee there will be no defects on your panels and you can’t guarantee how fast your panels will degrade, a warranty will cover for these problems provided they fall under manufacturer guarantees.
In general, the solar panel industry gives a 10-year manufacturer warranty and a 25-year performance guarantee. Manufacturer guarantees will protect you against any defects that may occur on a panel. Performance guarantees will protect you from panel degradation if it falls under the manufacturer’s guarantee. This, however, is typically only mentioned if you contact the manufacturer for it.
Some name brands other than Nature Power you should put into your consideration are names like LG, Panasonic, and SunPower. Name brands offer you an advantage since they will most likely have a good amount of reviews as well as offering you a longer warranty. For the brands listed above, they carry a 25-year performance warranty. A performance warranty guarantees you will not lose more than 10 up to 20 percent of power output capacity within 25 years. If it falls under that, you would get less from its claimed long-term value.
Features & Benefits

Frequently Asked Questions about Nature Power 120 Watt Briefcase Solar Panels 200
Q1. Can a 100-watt solar panel run a refrigerator?
To give you a direct answer, no. If you want to know why it won’t run a fridge, then we must first find out how much power a fridge would need to function. Generally, fridges consume between 100 to 250 watts. For a full day, a fridge uses around 1 to 2 kilowatt-hours.
On the solar panel side, solar panels’ power production depends on how much sunlight it gets. If you get 5 hours of direct sunlight, your panel would produce 500 watts. This is not enough to keep a fridge running as it needs an initial jolt to start-up and continuous power to keep running.
Q2. What can a 300-watt solar panel power?
As mentioned before, the amount of power produced by a panel depends on its size, how much sunlight it is getting, and the efficiency of the solar cells inside. In perfect conditions, your 300w solar panel would be getting direct sunlight to produce 300 watt-hours. Since we can’t guarantee perfect conditions every time, it is okay to assume it would produce about 85% of what it should. It would be ideal for you to pair a 300-watt panel with a 12V battery to store the energy and use it when needed.
After you charge the battery, you can run appliances such as a game console (150 watt-hours), a TV (150-200 watt-hours), and fans. The more devices you try to run on a single panel, the less run-time you get as appliances have varying ratings of wattage. If you want to get longer usage of the panel, consider powering appliances that have a lower power rating than others.
Q3. How much can you run off a 100-watt solar panel?
With all the previous information in mind, we can use that to determine how much we can run off a single 100-watt panel. Assuming we don’t have optimal conditions, we can estimate our panel will run at 85% of its efficiency. So we can calculate that it will produce 85 watt-hours. Paired with a battery, after a full cycle, we can power a laptop (60 watt-hours), lights or lamps with low power ratings (14 watt-hours), a modem (7 watt-hours), and more. The run-time of these appliances depends on how much power a device requires and how many devices are running off the panel. In our example, running a modem and lights will give you longer lasting run-time as opposed to a laptop and lights.
Q4. What will a 120-watt solar panel run?
A 120-watt solar panel produces 120 watt-hours in optimal conditions. Assuming we don’t have those conditions, it will most likely produce around 102 watt-hours or less depending on where you live. Depending on the number of hours you plan to use a device, a 120-watt solar panel should be able to power a router (6 watt-hours), certain LED bulbs, DVD player, or Blu-ray player (15 watt-hours), and more.
