Solar lamps are portable lighting that use solar cells to convert the energy from the sun into electricity, then store it in a battery. They can provide lighting in places where electricity is not readily available, such as rural communities, off-grid locations, and disaster-stricken areas.
Solar lamps come in various designs, from small portable lights to larger, more powerful systems that can light entire homes or buildings. You use them for general purposes, including indoor and outdoor lighting and more task-oriented activities like reading and studying.
How does a solar lamp work?
Solar lamps come with either a separate or integrated solar panel.
A solar panel is made from photovoltaic (PV) cells. They make up the primary component that converts the energy from the sun into electricity. The most common material used to make PV panels is silicon.
When sunlight strikes the solar cells, it causes a flow of electric current. The solar cells are connected in a series to form a solar panel. The electricity generated by the panel can be used immediately, stored in a battery for later use, or sent to the grid.
The solar cells in a PV panel are connected in series and parallel to create a desired voltage and current output. The panels are connected to an inverter that converts the DC (direct current) electricity generated into AC (alternating current) power, which most appliances and equipment can use.
Benefits of solar lamps
The benefits of quality solar lamps include their low cost over time, as they are durable, require no fuel and minimal maintenance, and their environmental friendliness, as they do not produce greenhouse gas emissions or contribute to air pollution. They also don’t require a costly installation process and can be easily installed by the end user. For example, BRIGHT’s solar lamps, Sunbell and Move, are ready to use instantly and designed to last several years.
Overall, solar lamps are a practical and sustainable solution for providing light in areas without access to electricity that already improves the lives of millions worldwide.
