Deductions & credits

A fuel cell converts compressed hydrogen gas to electricity.  A solar system is not a fuel cell system.  Solar systems are entered on a different line.

 

A solar system only qualifies if it provides power to the residence (hard-wired).   You can include the entire cost of the system including all components needed to make it work (solar panels, installation, inverter, batteries, connection to the electrical mains).  However, a portable solar generator is not eligible.
