Are you thinking about choosing a solar panel but don’t know where to start? Here’s a brief guide to help you out!
Solar panels come in two types: crystalline silicon and amorphous silicon. While crystalline silicon panels (monocrystalline and polycrystalline) have higher photoelectric conversion efficiency, amorphous silicon panels perform better in low light conditions and can be used indoors. Therefore, choosing the right panel depends on the intended use environment of the solar energy application product. When choosing solar panels, pay attention to the power of the panel. Generally, the power is proportional to the area of the solar cell. Keep in mind that a panel’s size doesn’t necessarily guarantee high power output. The gaps between solar cells in larger panels can be quite wide, affecting overall power.
Are you considering installing solar panels in your solar applications, but unsure of how to choose the right one? With so many options available, it can be overwhelming to decide.
Here are some key factors to consider:
1. Battery capacity: The selection of battery capacity directly affects the reliability of the system and the price of the system. When choosing a battery, make sure it can meet the power supply at night and store the energy of the solar panel during the day as much as possible. It should also be able to store the electric energy required for continuous rainy days and nights.
When connecting solar panels and batteries, make sure the rated output voltage of solar panels is 1.3 to 1.5 times higher than that of batteries.
2. Encapsulation form: There are three main encapsulation forms of solar panels- tempered glass lamination, ETFE lamination, and epoxy. Tempered glass lamination is the most durable with a working life of more than 10 years, while ETFE laminated solar panels have a service life of up to 5-7 years. Epoxy solar panels may look good, but their working life is only 1 to 2 years.
3. Understanding the selection of solar panel power is crucial to ensure optimal performance. Solar panel output power is random and varies depending on location, time, and environmental factors. The maximum power of solar panels is their ideal power, but the rated power is usually less due to output efficiency. In practice, the actual average power of a solar panel is around 70% of its rated power. When selecting the power of the solar panel, the power consumption of the load should be considered, and the power generation and consumption should be balanced. Keep in mind that solar panel power generation is also affected by season, climate, geographical environment, and illumination time.
We hope this helps you make an informed decision when choosing a solar panel that fits your needs.
