Portable solar panels are just as the name indicates – easy to carry around, set up, and use. These devices can provide you with electrical energy in cases when you find yourself away from power lines. Or there’s outages. Sunlight can charge these panels, which would later be used for powering any devices that run on electricity.
However, very few people understand the working mechanism of solar panels and their strength in providing efficient power. Whether you have already made the plunge or are on the fence about buying portal solar panels, we would like to share some tips to help seasoned veterans and newbies get the most sun power out of their portable solar power systems.
10 Tips to Get the Most out of Your Solar Power
1. Place the Solar Panel at an Optimal Angle
The angle at which you position your portable solar panel can significantly affect how efficiently it generates power. When the sun is directly overhead, it will be more difficult for solar panels to generate electricity. As the sun moves lower in the sky, the angle of incidence increases, meaning that more light hits your panels.
There are several ways to position your solar panel for maximum efficiency:
- Place it at an angle of 45 degrees from the horizontal. This is the optimum angle for capturing sunlight and converting it into energy.
- Place it at an angle closer to horizontal if you want to maximize power generation during the early morning or late afternoon when the sun is closer to being directly overhead.
- If you use multiple solar panels, place them side by side so they will all get as much direct sunlight as possible.
2. Install the Solar Panels in a Proper Direction
Not only the angle but the direction of your solar panels will also have a significant effect on the amount of power you can obtain from them. The best thing you can do is find out which direction is most beneficial for your location and locate your panel there. The easiest way to do this is with a compass, but if you do not have one handy, here are some general guidelines:
Keep in mind while placing your solar panel that you should place it in a way that it faces southward or eastward because these two directions are considered ideal for solar panels. If you have ample space, you can place multiple panels together and use more efficient energy.
Another important thing is that when placing multiple panels together, make sure they are facing southward or eastward and not westward. This will help improve their efficiency as well.
3. Keep the Panels Clean
One of the most important things you can do to maximize the efficiency of your portable solar panels is to keep them clean. Dust and dirt can reduce the amount of light that gets through, so your panels must work harder to produce the same amount of power. Debris on your panels can also block some from getting direct sunlight. That means they would not be able to generate as much electricity as possible if they were clean and unblocked.
Dirt and grime buildup is inevitable when using portable solar panels. While they are not precisely rugged enough for use in extreme conditions, they are designed to withstand some amount of abuse during their lifetime. However, if you are using them in an area where there is a lot of dust or dirt present, like an open field, then regular cleaning may be necessary to keep them operating at maximum efficiency.
The best way to clean this buildup is with water and soap. You can use any mild detergent to clean off the dirt and grime from your panels. However, you should never use harsh chemicals on your panels because they can damage them over time.
Moreover, you may be tempted to use a hose with high pressure, but the best way to clean a solar panel is with a rag or soft brush and a bucket of water. This will help prevent you from damaging the cells on your solar panel.
4. Monitor Your Solar Panel Output
The most important thing you can do to increase portable solar panels' efficiency is to monitor your solar panel output. Monitoring your solar panel output means that you are constantly aware of how much power your panels are generating and what their output is at any given time. This will allow you to adjust your usage and charging needs accordingly, ensuring you get the most out of your portable solar panels.
For example, if you notice that the sun is shining strong during certain times but not others, you can schedule tasks around those times when more power is available. You may also notice that there are times when sunlight is not as strong as it could be, such as when clouds pass overhead). This would be a good time to charge batteries instead of using solar power, as this will help maintain your battery life and ensure that they will be ready whenever needed in an emergency.
Some people also find it helpful to track how much energy they generate each month. This is so that they can see how much money they are saving on their electric bills by using clean energy instead of traditional fossil fuels or coal-fired power plants.
The most popular type of monitor for portable solar panels is a wattmeter or watt-hour meter. This type of monitor will tell you exactly how much energy has been produced or consumed over time so that you can see if there are any abnormalities in your system or if there are any problems with your equipment.
5. Avoid the Shade and Obstructions
Solar panels are the most efficient when they are in direct sunlight. Therefore, it is crucial to avoid shady areas and obstructions that can hinder the sunlight from reaching your solar panels.
Portable solar panels need direct sunlight to operate efficiently. If they are placed in the shade, they will not produce as much power as they would if they were in direct sunlight. It is essential to keep your panels out of trees and bushes where leaves or branches might partially block them.
Even if you have a clear view of the sun, there may be obstacles between you and it that are preventing the panel from producing adequate power. This includes buildings, houses, fences, and even cars. The closer you can get your panels to be directly facing the sun, the more efficient they will be at producing electricity for your device.
6. Use an External Charge Controller
If you have ever used a solar panel to charge your devices, you may have noticed that the panels cannot produce power when cloudy or overcast. This is because the sun's rays are diffused by clouds and no longer reach the solar cells on your panel. However, if you use an external charge controller with your portable solar panel, you can ensure that your device will be charged no matter what the weather is like outside.
A charge controller regulates the power flow from your portable solar panel into your battery. It also prevents overcharging and protects against short circuits, surges, and other dangers. The best ones have built-in fans and cooling systems to keep them from overheating, which is especially important if you live in a hot climate and plan to use your portable solar panel year-round.
The most basic models are called MPPT (maximum power point tracking) controllers. They use pulse width modulation (PWM) technology to track the maximum voltage at which your battery can absorb power without overcharging it. This allows them to deliver maximum charging current, which means they will work even if there is shade on your panels or the sun is not directly overhead.
7. Use Reflectors
Use reflectors to increase efficiency to get the most out of your portable solar panel. Reflectors are nothing more than pieces of metal that reflect sun rays at your portable solar panel, which increases its exposure to sunlight and allows it to produce more power.
Reflectors can be made from simple materials like aluminum foil or sheets. You may also use mirrors instead of aluminum sheets. They work the same way as the reflectors made out of aluminum foil or sheets but are more expensive than these materials. If you are using large reflectors, such as those designed for caravans or RVs, then it might be worth setting them up on a tripod so that they do not move around in windy conditions.
8. Choose Your Batteries Carefully
The ability of a solar panel to charge your portable devices depends on the battery quality. Most solar panels will have some power regulator built in, but if you are using batteries that are too old or damaged, they may not be able to hold their charge and will discharge quickly.
To ensure that your portable solar panel works efficiently, choose high-quality batteries designed for use with portable devices. These batteries are usually made from nickel metal hydride or lithium polymer cells, which can be found in various sizes and configurations.
Some people prefer rechargeable batteries because they cost less over time than disposable ones. However, if you want to maximize your battery life expectancy, it is best to use non-rechargeable alkaline batteries instead. Alkaline batteries last longer than rechargeable ones because they do not lose their charge as quickly when not used; when fully charged, alkaline batteries can last for up to 10 years.
9. Use Multiple Solar Panels
The efficiency of portable solar panels is tied to the size of the panels. A larger panel will have more surface area, so it can collect more sun rays. The downside is that they take up more space, so if you want to use a portable solar panel for camping or emergency backup power in an RV, you need to keep size in mind.
To get around this issue, multiple smaller solar panels can be combined to form one large array. This increases the amount of power that can be collected and stored by your portable solar generator but does not sacrifice portability in any way.
10. Use the Right Cables
If you have solar panels, you must ensure they are connected to the right cables and connectors. You cannot just connect any cable or connector to the panel; it can be ineffective. The most important thing is to use a suitable cable for your system. For instance, if you have a 12-volt battery and want to charge it using a solar panel, you need to get a 12-volt cable. If you do not have a suitable cable, it will not be able to charge your 12-volt battery as efficiently as possible.
