Would you install Solar? Any tips?

[Rafael Ro]

This is a general question... Do you think solar is worth it, for an area like a desert with plenty of sun and hot summers (AC blasting) raking up big electricity bills? 

But also more specific... Would you think that it would increase the value of a rental?

I'm considering buying them for our house and would likely break even in about 4years. The issue is that I plan to rent this house out in within the next 2 years (ie. before breaking, leaving the tenant reap the rewards). 

Would love to hear your thoughts.
