Introduction to solar lamp

- May 29, 2019-

1.A solar lamp is an electric light converted from solar panels to electricity. During the day, even on cloudy days, the solar generator (solar panel) can collect and store solar energy. As a kind of safe and environmentally friendly new electric lamp, solar lamp is getting more and more attention.

2.The system structure

Solar lamp consists of solar cell modules, some LED lamps,

Control box (its control box has charger, controller, battery) and light pole several parts. Solar panel luminous efficiency reaches 127Wp/m2, with high efficiency, which is very beneficial to the wind-resistant design of the system; The lamp holder is integrated with 1W white LED and 1W yellow LED on the printed circuit board and arranged into a lattice with a certain distance as the plane source. Control box body with stainless steel material, beautiful and durable; Maintenance-free lead-acid battery is placed in the control box, and a special charging controller for solar street lamp is successfully developed by adopting the patented slow pulse rapid charge and discharge technology. The system USES valve-controlled sealed lead-acid battery, because its maintenance is very little, it is also known as "maintenance free battery", which is helpful to reduce the maintenance cost of the system; The charging and discharging controller is designed with complete functions (including light control, time control, overcharge protection, overdischarge protection and reverse connection protection, etc.) and cost control, achieving high cost performance ratio.

3.The technology principle:

The working principle of solar lamp is simple. The solar cell made by using the principle of photovoltaic effect receives solar radiation energy in the day and converts it into electrical energy for output. After charging and discharging controller, it is stored in the battery. About 5V, the charging and discharging controller detects this voltage value and then ACTS, and the battery discharges the lamp. The battery discharged 8. After 5h, charge and discharge control action, battery discharge end. The main function of the charge and discharge controller is to protect the battery.

4.The working principle :

The solar power generation system consists of solar energy battery, solar energy controller and battery (group). If the output power supply is ac 220V or 110V, the inverter needs to be configured. The functions of each part are:

Solar panel

Solar panels: solar panels are the core part of the solar power generation system, and also the most valuable part of the solar power generation system Points. Its role is to convert the sun's radiation capacity into electricity, or sent to the storage battery, or to promote the load work. The quality and cost of solar panels will directly determine the quality and cost of the whole system;
