Solar Lamps always use the Off-grid Solar systems. It works independently, independent of the traditional power grid and is based on the solar energy in operation. Why? In case the solar lamp happens to be in rainy weather that can't gather the sun will it stop working?
Off-grid systems are independent of the grid and can be utilized even where there is no power infrastructure. Solar lamps capture energy from the sun through solar panels, which they store in batteries for use at night or on overcast days. In rainy weather, when it is impossible to collect energy, the solar lamp usually does not fail but will be affected by some effects; mainly, the shortening of the lighting time or reduction of brightness. Usually, this type of facility, like streetlights, does not come alone. Therefore, an off-grid solar energy system is used for saving resources and making full use of the electricity generated by solar energy during the day to light up the road at night.
Solar panels: Convert sunlight into electricity.
Energy storage battery: It stores the electricity collected during the day for use at night or on cloudy days.
Controller: manages battery charging and discharging to ensure that the battery is not charged or overdischarged.
Lamps (such as LED lights) : solar panels are charged during the day, and battery-powered lighting is used at night without power access
Because it does not rely on external power grids, solar lamps can be used independently in areas without grid coverage (such as rural, remote areas, outdoor places, etc.).
Solar lamps obtain their energy from solar panels, which are charged free during the day and store electricity for use at night. Compared to the traditional power system, the use of solar lamps does not need to pay the bill for electricity. The application of solar energy as clean energy reduces carbon dioxide emissions and is in line with the Sustainable Development Goals.
Solar lamps can easily and rather quickly be installed in area settings without power or unreliable supplies of power without complex cable systems and are very minimal in cost. A life expectancy of generally ten to twenty years with infrequent maintenance-clean the solar panel and perform a battery check on regular occasions for a long service life. Provide reliable lighting for areas such as remote locations and any places in emergencies with active use of night lights while limiting dependence on the grid for power.
performance in an off-grid solar system is very dependent on weather conditions; overcast days or rainy seasons lower the level of battery power, hence poor lighting.
The batteries themselves are also subject to a limited service life, generally requiring replacement every 3-5 years. And unlike traditional streetlights, whose up-front cost is lower, that of solar lamps is decidedly more expensive, especially for systems incorporating high-efficiency solar panels and large capacity batteries.
In short, it is independent power saving that is friendly to the environment. Its characteristics of the off-grid system are very suitable for those areas far away from the grid or with an unstable grid. This reduces laying a large number of lines and cables, which are usually more economic and environmental-friendly. Of course, when designing this, one will consider solar radiation, energy storage, and hence battery life to ensure the operation of the entire system will be reliable in the long term.
