: Why don’t all buildings use solar panels on their roofs to generate electricity?
In: Technology
The cost benefit analysis depends on a whole bunch of things. Your latitude, your local climate, for how much of the day a tree might be shading the solar panels, both now and as the tree grows in the future, what direction your roof faces, energy prices, how the laws and contracts regarding selling power back to the utility company works, how closely peak usage aligns with solar production, interest rates, etc.
