Description: Solar Panel Cell Polycrystalline Silicon 2V-10V Battery Charger Controller DESCRIPTION A solar cell is a photovoltaic semiconductor that directly uses sunlight to generate electricity. The photoelectric direct conversion method uses the photovoltaic effect to convert solar radiation energy directly into electrical energy, and the basic device for photoelectric conversion is the solar cell.The solar cell is a device that directly converts solar energy into electrical energy through the photovoltaic effect, a semiconductor photodiode, when the sun shines on the photodiode, the photodiode converts the sun's light energy into electrical energy to produce an electric current. When many cells are connected in series or parallel, it can become a solar cell array with relatively high output power. Parameter Description1. Due to the fact that the output power of solar panels depends on factors such as solar irradiance and panel temperature, the measurement of solar panels is carried out under standard conditions, defined as: atmospheric quality AM1.5, light intensity 1000W/m2, temperature 25 ℃2. Under this condition, the maximum power output by the solar panel is called the peak power (rated power). In many cases, the peak power of the component is usually measured using a solar simulator. In actual use, due to the insufficient intensity of sunlight to meet the testing conditions, the peak power is generally not reached.3. The nominal rated voltage and rated current are the peak voltage and current that can be achieved by testing the light intensity and temperature under load. In actual use, even in the scorching sun at noon in summer, the testing conditions cannot be met. Therefore, the following relationship exists:Open circuit voltage (without load)>rated voltage>actual operating voltageShort circuit current (output short circuit)>rated current>actual operating currentThe main factors affecting the output performance of solar panels are as follows:(1) Load impedance(2) Sunshine intensity(3) Temperature(4) Lighting angle and lighting area How to choose solar panels to power equipment?1. Confirm the power, voltage and current of the equipment to be driven.2. Confirm the power parameters of the solar panel and the equipment power parameters match, try to choose more than 30% of the solar panel, the effect will be better.3. If the power and current match, the voltage does not match, you need to buy a "voltage regulator module" to the corresponding voltage and current parameters corresponding to the equipment. NOTE1. Solar energy cannot store electricity, so direct sunlight is necessary to generate electricity.2. Solar panels cannot be used on cloudy or rainy days.3. Solar energy cannot be used for indoor lighting.4. Solar energy cannot be used when shining through windows. Package Including: According to your choice. About us: Good quality. Buy with confidence!
