A complete solar power supply system mainly consists of solar panels, controllers, batteries, and structural brackets, among which the solar panels are the most important part. The normal operation of the power supply system depends on the power generated by the solar panels, which means we need to pay more attention to the use of solar panels.  

When installing solar panels, we first need to calculate the plan and choose the most suitable solar panel according to different loads. For example, using a solar panel to supply power to a 20W light bulb requires the bulb to work continuously between 18:00 and 6:00 and be able to stand by for a day. According to the conditions, the light bulb needs to consume 0.24 kWh of electricity per day. Assuming a fixed lighting time of 4 hours per day, we need a 60W solar panel to generate electricity, and at the same time, a fully charged 12v20ah battery can be used to meet the standby needs for one day. Finally, we obtain a 60W 20ah solar power supply system.  

Secondly, when installing, we should pay attention to the surrounding environmental factors to avoid the solar panels being obstructed and affecting power generation. At the same time, we should also pay attention to the tilt angle and direction. The direct solar angle varies in different regions and seasons, so it is best to analyze the most suitable angle and direction during installation

In summary, the use of solar panels is not simple, but at the same time, it is not that complicated. The key is whether you really understand the usage method.
