what save more electricity? Solar panels over half my roof, or trees covering half my roof?

I was wondering which would save more money in the electricity arena (I know tree’s can damage roofs).
I had heard that the shade provided by trees covering your house can help to greatly reduce summer electric bills.
I had read that Solar panels need to go onto the south side of the house, and that is where the tree’s shade the house. So which is more cost effective?
Also I know many of the benefit’s tree’s can provide, as well as the negatives associated with large tree’s near houses.

Anyone help me to know what to consider when designing solar power for the home?

Hello,
I know little on solar power for the home. I understand that it is possible to convert power to chemical form then use it as electricity. My question is, what elements are involved and how is the sizing being done?
I need the power design to power lights (say 10), TV and radio.
