Solar has reached a great point where cost has lowered and quality has increased.
I have a 5 kw solar panel setup that takes up one side of the shed roof. The amount of power it generates is average 20 kilowatts each day, so if you are after a good power generation system for both on or off grid electricity supply, solar is a good option.
Wind has a lot of potential as it has the opportunity to generate at night time too.
If installing solar, make sure it's on the right direction for your location, as position is important. My 5 kw system could be generating over 28 kw per day if it was facing north here in australia.
If installing wind, make sure your location is down stream from regular wind currants.
