What are the disadvantages of using solar panels ?
disadvantage is that the sun doesn’t shine 24 hours a day. When the sun goes down or is heavily shaded, solar PV panels stop producing electricity. If we need electricity at that time, we have to get it from some other source. In other words, we couldn’t be 100% powered by solar panels. At the very least, we need batteries to store electricity produced by solar panels for use sometime later.
However, there are a couple of key things to note regarding this solar power disadvantage. Firstly, the sun actually does shine when we need electricity most. As humans (not vampires), our days more or less follow the movement of the sun. Society more or less wakes up when the sun rises. At the time of the sun’s greatest height and visibility, humans tend to be most active. At this time, we are of course using much more electricity than in the middle of the night, so electricity is in greater demand. (This also makes electricity more expensive in the middle of the day, making electricity produced from solar panels more valuable.)
