    The Best Portable Solar Chargers of 2023

    Adam has been writing about mobile technology since 2011. He is the former host of the Android Authority podcast, and his work has appeared in numerous publications.

    Rich Scherr is a seasoned technology and financial journalist who spent nearly two decades as the editor of Potomac and Bay Area Tech Wire.

    The best solar chargers use the sun’s abundant power to keep your devices and batteries topped off. Solar chargers aren’t just for nature enthusiasts. Anyone who spends time away from an electrical outlet will find them helpful.

    We recommend the X-DRAGON SunPower Solar Panel Charger for its 40W power output and high-efficiency cells. This charger doesn’t include a power bank to store all that juice, but if you are away from power and need to charge your phone or even your laptop, this is a great option. Opening the eight solar panels will give you plenty of power as long as there’s daylight.

    Best Overall

    X-DRAGON 40W Portable Foldable Solar Panel Charger

    Our best overall charger can produce up to 40W of juice from its eight efficient panels. It opens wide to collect a lot of sunlight with eight high-efficiency panels, but it folds down small enough to fit into your backpack. There’s no water-resistance rating here, so be careful not to get caught in the rain, and no battery is included. But if you have large items that need a charge, the X-DRAGON SunPower Solar Panel Charger is a great choice.

    You can plug in your phone and tablet, but you can also scale that up to your laptop with the five included different-sized barrel chargers and connection for your car battery. This is a great item to keep in your emergency car kit or your backpack for camping. The 18-month warranty will give you peace of mind too.

    Most Portable

    BigBlue 28W Solar Charger

    The Big Blue Solar Charger is a highly-portable solar charging solution that folds to a tiny 11.1 x 6.3 x 1.3 inches when closed. It’s long but narrow and thin, easily fitting into most backpacks. Included carabiners allow you to open and strap it to your bag outdoors.

    There is no built-in battery, but the three USB-A ports allow you to charge any phone or tablet quickly. The panels are waterproof, which our reviewer tested by submerging the cells in a bathtub.

    Our reviewer also noted that the advertised 28W output is misleading. There are four 7W panels which add up to 28 Watts. Unfortunately, the panels could output only around 17W maximum during our testing.

    There’s a pouch for holding cables or devices while charging, which is a nice bonus. Given its water resistance, we’d recommend this for hikers and campers, even in inclement weather. Of course, cloudy days will mean less charging, but at least you know your panels can stand up to it.

    What to Look for in a Portable Solar Charger

    Water Resistance

    Solar power works best outside, so looking for water resistance in case you unexpectedly get caught in the rain or snow is a good idea.

    Built-in Battery

    Solar panels generate power, and that power has to go somewhere. If you have a solar panel and nothing plugged in, the panels will not generate energy, which is fine, but a battery would allow you to generate power and store it until you need it.

    Power Output

    Keep in mind the kinds of devices you’ll be using. Most solar panels can do the job if all you need to charge is a phone or tablet. If you need to power something larger, such as a laptop or car, you’ll need a powerful setup to get the job done.

    designing, solar, cell, battery, charger

    That depends mostly on the cells’ efficiency and the amount of sunlight you’re getting. Solar panels are getting more and more efficient these days, which means they’re capable of generating a lot of power. On a bright, sunny day, it’s not unreasonable to think you can generate enough power for a phone and tablet or even bigger items.

    If it’s big enough, a solar panel can deliver a charge to your car’s battery to allow it to start. A jump start technically means you’re drawing from a power source to start your car right away. The solar option is more of a car battery charger, meaning you’ll need to wait some time for your car’s battery to charge before you can turn the key. But yes, it is possible.

    Solar panels should never be left in a window or in a car to charge. The glass from the window can FOCUS with light on the panels and cause them to overheat. Solar panels are meant to be outside and under the sun, or put away.

    Designing a Solar Cell Battery Charger

    The market for portable solar powered electronic devices continues to grow as consumers look for ways to reduce energy consumption and spend more time outdoors. Because solar power is a variable and unreliable, nearly all solar-powered devices feature rechargeable batteries. The goal is to extract as much solar power as possible to charge the batteries quickly and maintain the charge.

    Solar cells are inherently inefficient devices, but they do have a point of maximum power output, so operating at that point seems an obvious design goal. The problem is that the IV characteristic of maximum output power changes with illumination. A monocrystalline solar cell’s output current is proportional to light intensity, while its voltage at maximum power output is relatively constant (see Figure 1). Maximum power output for a given light intensity occurs at the knee of each curve, where the cell transitions from a constant voltage device to a constant current device. A charger design that efficiently extracts power from a solar panel must be able to steer the panel’s output voltage to the point of maximum power when illumination levels cannot support the charger’s full power requirements.

    The LT3652 is a multi-chemistry 2A battery charger designed for solar power applications. The LT3652 employs an input voltage regulation loop that reduces the charge current if the input voltage falls below a programmed level set by a simple voltage divider network. When powered by a solar panel, the input voltage regulation loop is used to maintain the panel at near peak power output.

    LT3652 Input Voltage Regulation Loop

    The input voltage regulation loop of the LT3652 acts over a specific input voltage range. When VIN, as measured via a resistor divider at the VIN_REG pin, falls below a certain set point, the charge current is reduced. The charging current is adjusted via a control voltage across a current sensing resistor in series with the inductor of the buck regulator charging circuit. Decreased illumination (and/or increased charge current demands) can both cause the input voltage (panel voltage) to fall, pushing the panel away from its point of maximum power output. With the LT3652, when the input voltage falls below a certain set point, as defined by the resistor divider connected between the VIN and VIN_REG pins, the current control voltage is reduced, thus reducing the charging current. This action causes the voltage from the solar panel to increase along its characteristic VI curve until a new peak power operating point is found.

    If the solar panel is illuminated enough to provide more power than is required by the LT3652 charging circuit, the voltage from the solar panel increases beyond the control range of the voltage regulation loop, the charging current is set to its maximum value and a new operation point is found based entirely on the maximum charging current for the battery’s point in the charge cycle.

    If the electronic device is operating directly from solar power and the input voltage is above the minimum level of the input voltage regulation loop’s control range, the excess power available is used to charge the battery at a lower charging rate. The power from the solar panel is adjusted to its maximum operating power point for the intensity level.

    Figure 2 shows a typical VIN_REG control characteristic curve. As the voltage on the VIN_REG pin increases beyond 2.67V, the voltage VSENSE – VBAT, across the current sensing resistor, increases until it reaches a maximum of 100mV, when VIN_REG is above 2.74V. As VIN_REG increases further, VSENSE – VBAT remains at 100mV. The expression for the input voltage control range is:

    If we linearize the portion of the curve in Figure 2 for VIN_REG between 2.67V and 2.74V, the following expression describes the current sensing voltage VSENSE – VBAT:

    The charging current for the battery would then be:

    Since the charging circuit of the LT3652 is a current controlled buck regulator, the input current relates to the charging current by the following expression:

    where η is the efficiency of the charger

    The input power can now be determined by combining Equations 4 and 5 with the input voltage, resulting in the following:

    Once RSENSE is selected for the maximum charging current and RIN1 and RIN2 are determined to select the input voltage current control range, Equation 6 can be plotted against the solar panels power curves to determine the charger’s operating point for various battery voltages. An example follows.

    Figure 3 shows a 2A, solar powered, 2-cell Li-Ion battery charger using the LT3652.

    First step is to determine the minimum requirements for the solar panel. Important parameters include the open circuit voltage, VOC, peak power voltage, VP(MAX), and peak power current, IP(MAX). The short circuit current, ISC, of the solar panel falls out of the calculations based on the other three parameters.

    The open circuit voltage must be 3.3V plus the forward voltage drop of D1 above the float voltage of the 2-cell Li-ion battery plus an additional 15% for low intensity start-up and operation.

    The peak power voltage must be 0.75V plus the forward drop of D1 above the float voltage plus an additional 15% for low intensity operation.

    The peak input power current is the product of the float voltage and the maximum charging current divided by the peak power input voltage and the efficiency of the charging circuit.

    Solving for these three equations, we can define the minimum requirements of the solar panel:

    The solar panel characteristics can be seen in Figure 4.

    The current sensing resistor, RSENSE, is determined from the maximum VSENSE – VBAT of 100mV divided by the maximum charging current of 2A

    The output feedback voltage divider network of RFB1 and RFB2 are determined next. The voltage divider network must have a Thevenin’s equivalent resistance of 250k to compensate for input bias current error. The VFB pin reference voltage is 3.3V.

    The next step is to set the peak power tracking voltage using the voltage divider network of RIN1 and RIN2 connected between the VIN and the VIN_REG pins.

    Verify the minimum and maximum peak power input tracking voltages.

    The final step in selecting resistor values is to determine the VSHDN voltage divider network consisting of RSHDN1 and RSHDN2. The VSHDN rising threshold is 1.2V ± 50mV with a hysteresis of 120mV. The voltage divider network wants to be set such that, when the voltage on the VIN pin is at VREG(MIN), VSHDN is at its maximum possible value.

    The VSHDN limits are now determined as:

    The LT3652 automatically enters a battery precondition mode if the sensed battery voltage is very low. In this mode, the charge current is reduced to 15% of the programmed maximum, as set by the current sensing resistor, RSENSE. Once the battery voltage reaches 70% of the fully charged float voltage (VFB = 2.3V), the LT3652 automatically increases maximum charge current to the full programmed value. The battery voltage threshold level between precondition mode and maximum charge current is determined as follows:

    Using and efficiency of 0.85, plot PIN over the range of VIN that is current controlled. This is the regulated VIN, or VREG, power line. The intersection of the VREG power line with the solar panel power curve is the operating point. As the battery charges, the slope of the VREG power line increases, indicating the increase in input power required to support the increasing output power. The intersection of the VREG power line continues to follow up the solar panel’s power curves until the charger exits constant current mode.

    The resulting plots are shown in Figure 4.

    Figure 4 shows the power output of the solar panel plotted at light intensity levels from 100W/m 2 to 1000W/m 2 in 100W/m 2 steps. At maximum light intensity (top curve in Figure 4) and the battery voltage just above the preconditioning level (VBAT(MIN) at 2A), the solar panel is producing more power than the charger needs. The solar panel voltage rises above the VREG control voltage and travels across the constant power line until it intersects the light-power-intensity curve for that intensity level (point A in Figure 4). As the battery charges, the input power increases and the solar panel operating point moves up the lightpower-intensity curve until the battery approaches full charge (point B). The LT3652 transitions from constant current mode to constant voltage mode and the charging current is reduced. The solar panel operating point moves back down the light-power-intensity curve to the open circuit voltage (point C) when the battery reaches its final float voltage.

    During the charging of the battery, if the light intensity diminishes, the operation point moves across a constant power line for the battery voltage until it reaches the new power-intensity curve. If the light intensity level continues to diminish, the operating point travels along this constant power line until it reaches the VREG power line. At this point the charging current is reduced until the operating point is at the intersection of the light-power-intensity curve and the VREG power line (point D for constant current charging at VBAT(FLOAT) with 800W/m 2 illumination). As the battery continues to charge at this light intensity level, the operating point moves along the new light-power-intensity curve until the battery approaches full charge.

    As darkness approaches, the operating point moves down the VREG power line until charging current ceases (point E) and the solar panel output voltage drops below the SHDN falling threshold at which point the LT3652 turns off.

    The remaining elements of the design, selection of output inductor, catch rectifier and timer capacitor, are outlined in the design procedure in the LT3652 datasheet along with PCB layout considerations.

    The maximum power voltage, for a monocrystalline solar cell, has a temperature coefficient of –0.37%/K while the maximum power level is –0.47%/K. This may be compensated for by letting RIN1 be a combination of a series resistor and a series NTC thermistor. The ratio of the two elements that comprise RIN1 and the value of RIN2 need to be adjusted to achieve the correct negative temperature of VIN while still maintaining the control range of VIN.

    The input voltage regulation loop of the LT3652 has the ability to seek out the maximum power operating point of a solar panel’s power characteristic, thus utilizing the full capacity of the solar panel. The float voltage regulation loop and its adjustable charging current enable the LT3652 to be used with many battery chemistries, making it a versatile battery charger. The added features of a wide input voltage range, an auto-recharge cycle to maintain a fully charged battery, a battery preconditioning mode, NTC temperature sensing, selectable C/10 or timed charging termination, a FAULT and a charging status pins fills out the full feature set of the LT3652. The LT3652 is available in a 3mm × 3mm 12-lead plastic DFN, package with an exposed pad.

    What Size Solar Battery Charger for Boat

    If you are a boating enthusiast, you understand the importance of having a reliable and sustainable power source for your boat batteries. Whether you’re fishing. cruising, or camping, you need constant and dependable power to make your marine experience comfortable and enjoyable.

    Fortunately, there is a reliable and sustainable way to power your boat battery. harnessing solar energy using a solar battery charger!

    Solar power is an easy and cost-effective way to keep your gadgets and appliances running smoothly. With the right size of solar charger, you can easily keep your boat powered up, no matter where you are.

    In this article, we will guide you on how to determine the right size solar-powered battery charger, and provide you with valuable information to help you choose the best Jackery solar generator for your needs.

    Features of a Solar-Powered Battery Charger

    A solar-powered battery charger is a system that harnesses the sun’s powerful energy to generate electricity. It typically consists of a solar panel, a solar charge controller, and wiring to connect everything together.

    The solar panel converts sunlight into electrical energy, while the charge controller regulates the amount of power going into the battery. It also prevents overcharging and ensures that the batteries are charged efficiently. The wiring ensures a safe and efficient connection between the components.

    Solar Panels

    There are three major types of solar panels available: monocrystalline, polycrystalline, and thin film panels. They all vary in appearance, performance, and cost.

    Monocrystalline panels are made from a single, pure crystal structure, which provides maximum efficiency and performance. The high-quality monocrystalline silicon allows these panels to deliver higher power output, occupy less space, and last longer than any other type of solar panel. This makes them the go-to option for many boat owners to provide power for appliances like TV, microwaves, and air conditioning.

    They have a uniform dark look and rounded edges that are easy to recognize. Jackery SolarSaga 200W Solar Panel is an excellent example of a monocrystalline solar panel. With over 23.7% efficiency, this panel can deliver maximum power output, allowing you to explore some of the most beautiful off-grid places.

    Polycrystalline panels are made of multiple interconnected crystalline silicon cells, which provide relative efficiency (around 15%) to monocrystalline panels but at a lower cost. These panels have the same dark, uniform look as monocrystalline panels, but the cells have a distinct square shape.

    If you are looking for a less expensive option, you can consider thin-film solar panels. These are made of amorphous silicon deposited in layers onto a substrate to form solar cells. This makes them lightweight and flexible, making them easier to install.

    However, these panels are less efficient and durable than mono or polycrystalline panels. They are also more sensitive to heat, which can reduce their power output.

    Solar Charge Controller

    A solar charge controller keeps the boat’s battery from overcharging by regulating the amperage and voltage delivered to the battery. This component is essential to prolong the life of your solar charger battery and prevent any damage.

    It allows smooths charging, maximizing the current up to approximately 80%, then reducing it as the battery reaches full capacity, and finally maintaining a float or trickle charge to keep the battery full and ready for use. Jackery’s solar generator has an advanced MPPT solar charge controller to ensure your battery lasts longer.

    Wiring

    Solar cables connect the components of a photovoltaic system and serve as a conduit where power flows from the solar panel to the battery and other devices. They are required to have resistance against UV light, extreme temperatures, and weather conditions.

    The size of the cable you need depends on both your system’s voltage and amperage. The thicker the wire; the higher the amp capacity. Jackery solar battery charger for boats is equipped with high-quality, corrosion-resistant cables that are specifically designed and certified for marine environments.

    Types of Solar Battery Chargers

    There are several types of solar battery chargers: Trickle charges, light-use charges, and high-output solar chargers. Each type of solar battery charger has its own specific features and capabilities, and the choice of which one to use depends on the intended application and the specific needs of the user. You want a solar panel battery charger for boats that can provide enough electricity to power your appliances while on the go.

    Trickle Charging

    Trickle charges are designed for maintaining the charge of a battery over a long period of time, making them ideal for use in low-power applications such as charging boats that are not used frequently.

    They prevent batteries from losing charge allowing you to run all your appliances even when not sailing. These low-voltage charges are designed to improve battery health and longevity. Since all batteries self-discharge, a trickle charger can keep your boat’s battery fully charged when it is on a trailer, at a mooring, or sitting at her slip.

    Light-Use Charging

    These are small, lightweight chargers that can be easily carried around and used to charge small electronic devices such as smartphones, tablets, and cameras. They are portable so they can be used anywhere and anytime.

    Heavy Power-Use Charging

    High-output solar chargers are designed for charging multiple batteries at once or for powering up large appliances, lighting systems, and other heavy-duty equipment. They can deliver high power outputs, making them ideal for use in remote off-grid locations where there is no access to traditional power sources.

    Jackery’s solar battery chargers are high-output solar panel kits specially designed to provide maximum power output and efficiency that are sure to make your boat’s living experience enjoyable.

    Benefits of Solar Battery Charger for Boat

    Installing one or more photovoltaic solar panels on your boat is a great way to keep your appliances running. They help augment or replace other power sources, such as fuel generators.

    Photovoltaic solar chargers such as Jackery Solar Generator 2000 Pro provide clean and free energy, whisper-silent operation, and zero emissions. In addition, they can also help you save money on fuel costs and reduce your environmental impact.

    Harnesses the Sun’s Energy

    When the sun shines onto a solar panel, it is absorbed by the photo-voltaic cells and converted into usable electricity. This energy is then used to light up your boat and power your electronics. This is a truly renewable, sustainable, and eco-friendly solution

    Silent and Fuel Free

    This is perhaps one of the biggest advantages of using solar power. As opposed to fuel-powered generators, solar panels are whisper-silent when generating electricity. This makes them great for use on boats, where noise can be a major nuisance. They are also fuel-free, so you don’t need to worry about running out of fuel when you’re in the middle of nowhere.

    Little to No Maintenance

    Since solar panels are designed to be used outdoors, they can withstand harsh elements such as saline water and high temperatures. They also don’t have moving parts, so there is virtually no maintenance required. All you need to do is keep them clean and check the wiring periodically to ensure optimum performance.
