A solar lighting unit, also called a solar candle or solar light, is a portable lighting system consisting of a solar lamp, solar batteries, charge controller, lampshade, electrical cables and an inverter to control the flow of current. Most solar lights are made with durable polycarbonate or strong glass and are designed to withstand harsh weather conditions. In most cases, they can be used in any kind of weather condition, making them an excellent choice for those who have outdoor camping trips to RV parks. They are designed to function for at least two years or even more depending on the type of battery that powers it.
Typically, solar lights use solar cells as their light source den nang luong mat troi 300w. These solar cells are charged with solar electricity from the sunlight during the day and when the sun sets, the stored solar electricity is automatically converted into usable household current using a small battery. The battery stores the solar electricity in deep discharge deep cell – designed to be flooded with water in times of low sunlight. This allows the solar cells to continue operating even in cloudy weather.
Solar lights work in much the same way as other household lighting systems. There is a switch on the wall or roof that switching on the electricity to the solar panel. As long as there is enough sunshine, the solar panels will operate continuously producing adequate electricity to power the LED lamps that are built into the base and the bulb on the top. The LED lamps also absorb some of the heat from the sun. When the sun is not out for long, the panels will stop producing any electricity. This saves money on your energy bill since you do not need to continuously produce additional electricity for your lights to work.
Depending on the amount of sun you receive, the amount of battery charge that your solar light receives may vary. Some lights can work well for one to two hours without needing any additional charge from your battery. As your battery power wears down though, some lights will require their own battery backup to continue working during your dark nights.
A newer type of solar lights made to use a photovoltaic panel rather than a traditional solar panel. Instead of using the sun’s rays to create electricity, the panels collect energy from the light rays by photovoltaic cells. These cells are made of a material that absorbs both energy from the sun’s rays and the heat of the summertime. As this photovoltaic material works overtime it will slowly charge up from the battery. Once the charge is full then the light is turned on automatically and starts producing electricity.
In a sense solar energy has been around since the beginning of time. Even before the sun was discovered, people had used the light it provides to dry food, keep clothes warm, seal water, and turn water into wine. However, in modern times we harness that same power for electrical purposes. This electrical energy is in the form of alternating current or AC. Most modern day lights use this type of electricity for their source of illumination. You can have solar energy night lights to supplement your other lighting and save money on your electric bill.
