The large problem with solar power now-a-days is that panels are highly inefficient, and the batteries you have to use to store solar power are also highly inefficient. Sure, you could have a 10w panel on the roof to trickle charge a battery in the event of power failure, but it would be more practical to use a UPS.
MIT has been making huge leaps and bounds in the past months with recent discoveries on how to improve the efficiency of solar panels, and storage devices.
