Does installing solar power panels increase the value of my house?

Residential Solar Power Question

I am thinking of installing solar panels on my house, the only worry I have is that I am not intending to stay in my home for much more than 5-7 years.

My investment in solar power panels will have only just paid for itself in that time, but I have heard that having solar power on a house can increase its value.

Will the increase be enough to pay me back for my investment if I leave early and what can I do to make sure than I get the maximum return on my investment?
