What is panel conversion efficiency
Solar Outdoor Post Cap Lights relies on solar panels for energy conversion. Panel conversion efficiency refers to the proportion of solar energy converted into electrical energy. The higher the efficiency, the more electrical energy the battery cell per unit area can generate, and the more stable the battery life and brightness performance of the lamp. For outdoor lighting products, conversion efficiency directly determines the use experience of the lamp in cloudy, winter or low-light conditions.
Monocrystalline silicon solar panel efficiency
Solar Outdoor Post Cap Lights mainly uses monocrystalline silicon solar panels. The conversion efficiency of single crystal silicon materials is usually between 18% and 22%. Because the crystal structure is complete, the current transmission path is short, and the power loss is small, single crystal silicon can generate more electrical energy than polycrystalline silicon under the same area. For column headlights that need to be installed on a limited area, the advantages of monocrystalline silicon panels are particularly obvious, which can ensure that stable lighting time is still obtained under a smaller volume.
Polysilicon solar panel efficiency
Some of the less expensive Solar Outdoor Post Cap Lights will use polysilicon panels. The conversion efficiency of polysilicon is usually between 15% and 18%. Although it is slightly less efficient, it has lower manufacturing costs and is cost-effective. For courtyard users with limited budget and low requirements for lighting brightness and battery life, the polysilicon solution is still attractive. However, in environments with long-term rainy weather or insufficient sunshine conditions, the performance of polycrystalline silicon may not be as stable as that of single crystal silicon.
Effect of conversion efficiency on lighting duration
The higher the conversion efficiency of the battery board, the higher the charging efficiency. Taking the same area of the battery panel as an example, monocrystalline silicon may provide enough power to support the lamp lighting for 8 to 10 hours after four hours of charging, while polycrystalline silicon may only maintain illumination for 6 to 8 hours under the same conditions. For homes that focus on night landscape atmosphere or patios that require safe lighting, choosing efficient solar panels is particularly critical.
The relationship between conversion efficiency and seasonal changes
Solar Outdoor Post Cap Lights is able to quickly charge the panels when the sun is abundant in spring and summer, and the lighting effect can basically meet the needs even if there are differences in efficiency. However, in autumn and winter, the sunshine time is shortened, the sun's altitude angle is reduced, and the light receiving area and energy absorption capacity of the panel will be affected. If the panel is inefficient, it is often in the event of insufficient lighting or extinguishing early. Therefore, choosing a panel with higher conversion efficiency can effectively alleviate the impact of seasonal insufficient light.
The relationship between conversion efficiency and product life
High-efficiency solar panels can be charged faster under the same conditions, reducing the number of deep discharges of the battery, and helping to extend the cycle life of the battery. At the same time, high-efficiency battery panels usually have better waterproof and dustproof performance with better packaging technology and materials. This means that in long-term outdoor use environments, high-efficiency panels can not only ensure lighting performance, but also extend the service life of the entire Solar Outdoor Post Cap Lights.
