In response to the national call for “carbon neutrality and carbon peaking”, photovoltaic power generation has gradually entered the homes of more and more ordinary people. Friends may encounter some problems during the use of photovoltaic power generation.

We have collected some of the photovoltaic issues that have received the most feedback from everyone for answers, to help everyone overcome difficulties and better utilize the role of solar energy.

Question:

Should low wattage or high wattage solar panels be chosen when selecting solar panels?

Answer:

Choosing a lower wattage solar panel to charge your device may be slower than the charging speed you are accustomed to.

So in order to achieve the best charging effect, before choosing a solar panel, you can first take a look at your device specifications and calculate how much power their charging cables allow.

In this way, it can be convenient for you to choose the appropriate wattage of solar panels, preventing you from purchasing solar panels with power exceeding the limit of your device.

Question:

When do I need to choose a convenient outdoor mobile power supply?

Answer:

If you want to still be able to use solar power when there is no sunlight, it is particularly necessary to choose a suitable convenient outdoor mobile power source.

You can consider lithium iron phosphate batteries, which are efficient and lightweight, and can be paired with multiple portable solar panels for long-lasting power supply, allowing you to fully enjoy outdoor life day and night.

Question:

How to extend the service life of solar batteries?

Answer:

1. To prevent overcharging, strictly follow the manufacturer’s instructions to provide the charging voltage value when charging the battery.

2. To prevent over discharge, the depth of discharge is closely related to the number of charging and discharging cycles (service life) designed for the battery. Severe over discharge can cause the battery to fail to activate to its optimal state, or even be scrapped.

3. Prevent undercharging, which is the opposite of overcharging. Undercharging is mainly caused by low charging voltage settings, or problems with the rack system.

4. Controlling temperature plays an important role in the lifespan of solar cells, and it is necessary to monitor and maintain the temperature of solar cells and environmental temperature control.
