A solar charger converts solar energy into electrical energy and stores it in a battery. The battery can be any form of electricity storage device and generally consists of three parts: photovoltaic solar cells, batteries, and voltage regulation components. The batteries are mainly lead-acid batteries, lithium batteries and nickel-metal hydride batteries. The load can be mobile phones and other digital products, and the load is diversified.
Type 1, solar charger with lighting function, built-in energy-saving super LED lighting, very energy efficient. If used for LED lighting only, it can be used for 3-30 hours depending on the capacity of the built-in battery.
Type 2 is a solar charger with its own charging function. This charger does not have other extensive functions. The advantage isthat this type of charger has a large capacity and is very suitable for professional external power supplies.
Type 3, a solar charger that supports adjustable power supply. Currently, it generally supports 5V and 9V can be adjusted.
The conversion rate of current market-oriented solar panels is still relatively low, generally only 16.5%. Domestic Suntech can reach 17%, and some overseas people have reached 25%.
Researchers at Rensselaer Polytechnic Institute in the United States developed a new coating in 2008. Covering it with solar panels can increase the solar absorption rate of the latter to 96.2%, while That ordinary solar cells have a solar absorption rate of the board is only about 70%.
The new coating mainly solves two technical problems. One is to help solar panels absorbber almost the entire solar spectrum, and the other is to allow solar panels to absorb sunlight from a wider angle, thereby increasing brightness. efficiency of solar energy. How effectively a panel absorbs sunlight.
Ordinary solar panels can generally only absorb part of the solar spectrum and generally only work effectively when they absorb direct sunlight. Therefore, many solar installations are equipped with automatic adjustment systems to ensure that the solar panels always maintain good brightness. the angle relative to the sun that is most conducive to energy absorption.
The importance of solar cell phone charger
A solar cell phone charger is a device that uses solar energy to charge cell phones. It generally consists of a solar panel anda mobile phone charger module. The solar panel converts solar energy into electrical energy, which is then transmitted to the phone charger module. The mobile phone charger module converts electrical energy into the voltage required by the mobile phone and transmits it to the mobile phone battery for charging.
The advantage of using a solar cell phone charger is that it does not require external power, can be used outdoors and does not produce carbon emissions. However, its charging speed is generally slower than traditional phone chargers, and charging efficiency decreases in bad weather or when used indoors.
The solar cell phone charger is environmentally friendly, energy-saving, convenient and practical, emergency backup and cost-effective.
1. Environmental protection and energy saving. The loadsSolar cell phone chargers use solar energy to charge without using the power grid, significantly reducing electricity demand and reducing environmental pollution.
2. ConveniencePractical, the solar cell phone charger can be taken with you wherever you go, whether during travel, camping, outdoor adventures and other activities, as long as there is sunshine, you can charge your cellphone.
3. Emergency backup. In case of emergency, the solar cell phone charger can be used as a backup power source to charge mobile phones and ensure smooth communication.
4. Economical and affordable, the price of the solar cell phone charger is low and there are no additional charges for charging. Long-term use can reduce charging costs.
