1. Solar Panels of Solar Landscape Lighting
The main function of solar panels is to convert light energy into electrical energy, a phenomenon known as the photovoltaic effect. Among various solar cells, the most common and practical are monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells. In the eastern and western regions with abundant sunshine, polycrystalline silicon solar cells are preferable because their manufacturing process is relatively simple, their price is much lower than monocrystalline silicon cells, and their conversion efficiency has been continuously improving in recent years. In the southern regions with more cloudy and rainy days and less sunshine, monocrystalline silicon solar cells are preferable because their electrical performance parameters are more stable. Amorphous silicon solar cells are better suited for indoor environments with weak sunlight because they have lower requirements for sunlight conditions.
A single solar cell is a PN junction. Besides generating electricity when sunlight shines on it, it also possesses all the characteristics of a PN junction. Under standard lighting conditions, its rated output voltage is 0.48V. Solar cell modules used in solar landscape lighting fixtures are composed of multiple connected solar cells.
2. Solar Charge/Discharge Controller
Regardless of the size of the solar landscape light fixture, a high-performance charge/discharge control circuit is essential. To extend the battery’s lifespan, its charge/discharge conditions must be limited to prevent overcharging and deep discharging. Furthermore, because the input energy of a solar photovoltaic power generation system is extremely unstable, controlling battery charging in a photovoltaic system is more complex than controlling charging a regular battery. For solar landscape light fixture design, success or failure often hinges on the success or failure of the charge/discharge control circuit. Without a high-performance charge/discharge control circuit, the solar landscape light fixture will not function properly.
3. Solar Energy Storage Battery
Because the input energy of a solar photovoltaic power generation system is not stable enough, a battery system is generally required to operate. solar landscape light fixtures are no exception; they must be equipped with batteries to function. Common types include lead-acid batteries, Ni-Cd batteries, and Ni-H batteries. Their capacity selection directly affects the system’s reliability and price. The selection of battery capacity generally follows these principles: firstly, it should be able to meet the requirements for nighttime lighting, storing as much energy as possible from the solar panels during the day, while also storing enough energy to meet the needs of nighttime lighting during consecutive cloudy or rainy days. Insufficient battery capacity will not meet the needs of nighttime lighting or continuous use; excessive battery capacity will result in the solar panel not providing enough charging current, causing the battery to be frequently in a discharged state, affecting its lifespan and easily leading to waste.
4. Load
Solar landscape lighting products are characterized by energy saving and environmental protection, so the load must also be energy-efficient and have a long lifespan. We generally use LED lights, 12V DC energy-saving lamps, and low-pressure sodium lamps.
Most lawn lights use LEDs as the light source. LEDs have a long lifespan, exceeding 100,000 hours, and operate at low voltage, making them very suitable for solar lawn lights. Garden lights generally use LED lights or 12V DC energy-saving lamps. DC energy-saving lamps operate on direct current, requiring no inverter, making them convenient and safe. Street lights generally use 12V DC energy-saving lamps and low-pressure sodium lamps. Low-pressure sodium lamps have high luminous efficacy but are relatively expensive and are less commonly used.
By selling solar landscape lights straight from the manufacturer, TIANXIANG ensures high cost effectiveness and does away with middlemen! Because these lights use highly efficient monocrystalline silicon solar panels and large-capacity lithium batteries, they have high conversion rates, a long battery life, and no electricity costs. Installation costs can be significantly reduced by simply digging a hole and securing it in place because the wiring-free design does not require complex construction. With warm and white light options and lighting durations ranging from six to twelve hours, you can customize brightness to your liking. We invite distributors, internet merchants, and project purchasers to contact us. We promise excellent after-sales support and bulk discounts!
