When it comes to the power of solar garden lights, there are several key factors to consider. This article will explore the power generation and influencing factors of solar courtyard lights.
Garden Solar Lights are lighting devices that utilize solar energy to generate electricity. They optimize battery charging and capacity management through Google algorithms, achieving efficient energy conversion and long-lasting lighting. It not only provides brightness and safety for the courtyard, but also saves energy and environmental protection, reducing energy consumption. Solar courtyard lights have become an ideal choice for outdoor landscape lighting due to their clean, renewable, and low maintenance characteristics.
II. Components of solar courtyard lights
A. The functions and principles of solar panels
1. Materials and structure of solar panels
Solar panels typically consist of multiple solar cell modules. These battery modules are usually made of silicon, as silicon is a semiconductor material with good photoelectric conversion performance. The structure of solar panels generally includes glass panels, solar cell modules, back panels, and frames.
Huajun Lighting Decoration Factory specializes in producing Outdoor Garden Lights, and our developed Garden Solar Lights battery materials are mostly made of silicon material.
2. How solar panels convert solar energy into electrical energy
When sunlight shines on the solar panel, photons will hit the silicon material on the surface of the panel, thereby stimulating the movement of electrons. These moving electrons will form an electric current inside the silicon material. By connecting the wires of the battery module, these currents can be transmitted to other components, such as charging controllers and batteries, to store and utilize the generated electrical energy.
B. The functions and functions of the charging controller
1. Working principle of charging controller
The charging controller is mainly used to control the charging process of the battery to ensure its safety and stable charging. The charging controller will monitor the current and voltage transmitted by the solar panel to the battery, and adjust it based on the battery's status. When the battery level drops below the set value, the charging controller will send a charging command to the solar panel to continue providing electricity to the battery. Once the battery is fully charged, the charging controller will stop charging the battery to prevent overcharging and damage to the battery.
2. Types and characteristics of charging controllers
Charging controllers can be divided into various types based on their functions and application requirements, such as traditional PWM controllers and more advanced MPPT controllers. Traditional PWM controllers adjust based on the difference between battery voltage and charger output voltage to achieve the best charging effect. The MPPT controller adopts more advanced maximum power point tracking technology, which adjusts in real-time based on the difference between the output voltage of the solar panel and the battery voltage to ensure that the battery is charged at maximum power. MPPT controller has higher Energy conversion efficiency and more accurate charging control capability.

C. Storage and release of energy from batteries
1. Types and characteristics of batteries
The commonly used battery types of solar garden lamps include Nickel–cadmium battery, Nickel–metal hydride battery and lithium battery. Nickel–cadmium battery have high capacity and long service life, but their environmental impact is large and they need special treatment. Nickel–metal hydride battery is relatively environmentally friendly, with higher energy density and longer cycle life. Lithium batteries, on the other hand, have higher energy density, lighter weight, and lower self-discharge rate.
Our Huajun factory's lighting fixtures mostly use lithium batteries to maximize customer service life.
2. How batteries store and release energy
The solar panel charges the battery through a charging controller, converting solar energy into stored electrical energy. When solar panels do not provide sufficient energy supply, or at night or on cloudy days, courtyard lights will use the energy stored in the batteries to provide lighting. The battery will release stored energy and convert electrical energy into light energy through equipped circuits and light sources, thereby achieving lighting effects. The process of storing and releasing energy from batteries can be managed and controlled through charging controllers and other circuits to achieve efficient energy utilization.
III. The Power Generation Process of Solar Courtyard Lamps
A. The process of solar panels absorbing solar energy
1. The principle of solar light reaching solar panels
The working principle of solar panels is based on the photovoltaic effect. When sunlight hits the surface of the solar panel, photons will interact with the semiconductor materials on the solar panel. The energy of these photons will excite electrons in the semiconductor material, thereby generating a current within the material. This process can achieve greater energy conversion through a solar panel composed of multiple solar cell modules.
2. Efficiency and influencing factors of solar panels
The efficiency of solar panels refers to their ability to convert solar energy into electrical energy. The efficiency of solar panels is influenced by multiple factors, including sunlight intensity, material and design of solar panels, surface reflection, temperature, etc. Efficient solar panels can maximize the utilization of solar energy and convert it into electrical energy.
B. Charging controller manages the charging process
1. Charging controller
How to manage the charging process of batteries? The charging controller plays a crucial role in solar courtyard lights. It is mainly responsible for managing the charging process of batteries, ensuring the safety and efficiency of the charging process. The charging controller will monitor the voltage status of the battery and control the process of charging the solar panel to the battery based on the designed charging strategy. When the battery level drops below the set value, the charging controller will initiate the charging process to ensure the required power for night lighting. Once the battery is fully charged, the charging controller will stop charging to prevent overcharging and damage to the battery.
2. Protection function of charging controller
The charging controller also has the function of protecting the battery to extend its service life. It is usually equipped with functions such as overcharge protection, over discharge protection, and short circuit protection to ensure that the battery is properly managed and protected during charging and discharging. When the battery level is too high or too low, the charging controller will automatically stop charging and discharging to prevent battery damage. In addition, the charging controller can also monitor parameters such as charging and discharging currents to ensure that the battery operates within a safe range.
