No.
Solar panels cannot directly power charging devices.
Since the power of solar panels is low and the output voltage is extremely unstable, they are not suitable for connecting to loads. To achieve a power supply, a number of individual cells must be strung together, connected in parallel and tightly sealed into the components.
Solar panels (also called solar cell modules) are the core part of the solar power generation system and the most important part of the solar power generation system. The power output of solar panels is unstable and changes with the intensity of sunlight. It is necessary to connect a battery and add an inverter on the back, so that it can support 220 AC load.
Detailed informations:
The main function of cells is to produce electricity. The main market for power generation is crystalline silicon solar cells and thin-film solar cells, both of which have their own advantages and advantages. disadvantages. Crystalline silicon solar cells have relatively low equipment costs, but the consumption and costs of the cells are high, but the photoelectric conversion efficiency is also high, which makes them suitable for power generation under the outdoor sunlight;
Thin-film solar cells have relatively low equipment costs. It is higher, but the battery consumption and cost are very low, but the photoelectric conversion efficiency is more than half of that of crystalline silicon cells, but the effect of lowbrightness is very good and can also generate. electricity under ordinary light, like solar cells in calculators.

How to use and install photovoltaic panels
It's very simple. Connect the positive and negative electrodes of the. solar panels and simply connect the positive and negative poles of the power bank. Note that the output voltage of the solar power must match the voltage of the power bank.
Three blocks can be connected in series, with the negative terminal of one connected to the positive terminal of the other. As for the time needed for a full charge, you can determine that yourself. Power divided by voltage = current, but there won't be much current used. 3 pieces seems too few and the charging current is too low.
How to use and install photovoltaic panels
TheThe function of solar panels is to convert light energy from the sun into electrical energy, then produce direct current and store it in the battery. Solar panels are one of the most important components of solar power generation systems. Their conversion rate and lifespan are important factors that determine the value of solar cells.
The module design conforms to the International Electrotechnical Commission standards GB/T9535-98 and IEC61215, and the cells are designed according to the GBT6495 standard. 36 or 72 polycrystalline silicon solar cells are used in series. to form different types of 12V and 24V components. This component can be used in various household photovoltaic systems, independent photovoltaic power plants and grid-connected photovoltaic power plants.
Features of raw materials Cells: Use solar cells inhigh efficiency polycrystalline silicon (above 15.5) (above 16.5 monocrystalline silicon).Chip packaging to ensure sufficient power generation from solar panels. Glass: Low iron tempered suede glass, also known as white glass, with a thickness of 3.2mm, has a light transmittance of more than 91 in the response wavelength range solar cell spectral range from 320 to 1100 nm and has high reflectivity. for infrared light above 1200 nm. This glass is also resistant to solar ultraviolet rays and light transmission does not decrease. EVA: A layer of high-quality EVA film with a thickness of 0.78 mm and added with anti-UV agent, antioxidant and curing agent is used as the sealant of the solar cell and as bonding agent with glass and TPT. It has high light transmittance and anti-aging ability.
TPT: The cRear apot of the solar cell - the fluoroplastic film is white and reflects sunlight, thus slightly improving the efficiency of the module. Due to its high infrared emissivity, it can also lower the operating temperature of the module. The components also help improve the efficiency of the components. Of course, this fluoroplastic film first meets the basic requirements of aging resistance, corrosion resistance and airtightness required by solar cell packaging materials. Frame: The aluminum alloy frame used has high strength and strong resistance to mechanical impact. Basic parameters standard test conditions: (AM1.5) Irradiance 1000W/m2 Battery temperature 25℃ Insulation voltage: ≥600V (≥1000V above 100W) Frame earth resistance: ≤10hm Wind pressure : 2400Pa Filling factor: 73% Short-circuit current Coefficienttemperature coefficient: 0.4 mA/℃ Open circuit voltage temperature coefficient: -60 mV/℃ Operating temperature: -40 ℃ ~ 85 ℃ Component wiring instructions: Tools required for installation include a slotted screwdriver M4 and a Phillips screwdriver.
Open the junction box cover. Insert the M4 flathead screwdriver into the installation hole of the junction box cover according to the mark on the junction box. Lift it gently with one foot. In this way, first lift the junction box cover. four corners of the junction box to open the cover. There is a wiring cover inside the box and when you lift it you can see three wiring terminals. There are positive and negative pole signs next to the left and right terminals of the battery board, which represent the positive and negative poles of the battery output voltage under working conditions. According toAt power demand, the positive pole is connected to the positive pole. and the negative pole is connected to the negative pole. The wiring adopts mechanical compression method. Use an M4 Phillips screwdriver to unscrew the compression screw from the terminal. Peel off the wire and pass it through the G7 cable seal, insert it into the wiring hole and compress the wire firmly. After the wires are connected, cover the protective cover, use an M4 Phillips screwdriver to screw the self-tapping screws into the screw holes, fix them, and then close the junction box cover to complete the wiring of the battery board . Grounding the Battery Board A ground screw is installed on the back of the battery board. Attach the ground wire to the ground screw to safely ground it.
