When choosing solar panels for solar street lights, multiple factors need to be considered to ensure their efficiency, reliability, and adaptability to specific application environments. Here are some detailed considerations of the main factors:

Conversion efficiency:

Conversion efficiency is an important indicator for evaluating the performance of solar panels. It refers to the efficiency of solar panels in converting solar energy into electrical energy.
Choosing solar panels with high conversion efficiency can better utilize solar energy, thereby improving the illumination time and brightness of solar street lights.
Generally speaking, it is more appropriate to choose solar panels with a conversion efficiency of over 18%, and some well-known brands of solar panels even have a conversion efficiency of over 20%.

Power and size:

The power and size of a solar panel directly determine the amount of electricity it can generate.
Larger solar panels typically have higher power, but also require more installation space.
When making a choice, it is necessary to weigh the power requirements and installation environment of the street lamps.

Durability:

Solar street lights are usually installed outdoors and need to withstand various harsh weather conditions.
Choosing solar panels with excellent durability is crucial to ensure their long-term stable operation.

Temperature coefficient:

The temperature coefficient reflects the performance changes of solar panels at different temperatures.
Choosing solar panels with lower temperature coefficients can reduce the impact of high temperatures on power generation performance.

Brand and Quality:

Choosing well-known brands of solar panels usually means higher quality assurance and better after-sales service.
Meanwhile, reviewing the certification and testing reports of a product is also an important means of evaluating its quality.

Installation environment:

The installation environment of solar panels also has a significant impact on their performance.
Factors such as lighting conditions, shading conditions, and installation methods need to be considered for the installation location.
For example, ensure that solar panels are installed in sunny and unobstructed areas, and adjust the installation angle according to the local latitude and season.

Cost budget:

When choosing solar panels, it is also necessary to consider the cost budget.
The prices of solar panels of different brands, models, and performance vary greatly, and it is necessary to choose according to the actual situation.

In summary, when selecting solar panels for solar street lights, it is necessary to comprehensively consider multiple factors such as conversion efficiency, power and size, durability, temperature coefficient, brand and quality, installation environment, and cost budget. By weighing these factors, the most suitable solar panel for specific application needs can be selected to ensure the efficient and stable operation of solar street lights.
