Should we have solar panels at home?

I believe we should have solar panels at home.

Firstly, if we use electricity we will be wasting resources. Coal is a nonrenewable resource. People use it to make electricity. But if we use solar panels, we will be catching the sunlight to make electricity instead.

Secondly, with solar p0wer you don't have to pay for how much power you use. But you have to pay for how much you use with power from power lines.

Thirdly, generating power from other resources such as coal, makes pollution but solar power doesn't because it is energy from the sun.
