Are solar panels worth it?

More efficient panels will tend to cost more. Before buying expensive panels, consider the size of your roof. If you have enough space, cheaper, less efficient panels could end up being more cost-effective over time. However, if space is limited, you would probably want to maximise efficiency to get more power out of fewer panels.
