I'm curious why so few ppl\companies use solar panels? It's so cheap and it'lll save some resourses of our planet. So why don't we use it?
Solar panels are a great way to get energy from the sun instead of burning coal or oil. Here where I live there are some big solar panels farms that can give electric in the daytime and we also have windmills that can generate electricity around the clock unless its a day without wind, however on nights without wind there's no electricity from those resources so electric still comes from coal on those occasions.
They are more expensive to install and are less effective compared to the electricity,most effective method of making electricity is through nuclear power plant but it have high risky.
