A typical PV solar panel system has:

Solar panels
An inverter
Hardware to mount the panels
Cables for electricity
A system to monitor the panels
A battery to store energy (optional)

When sunlight hits the solar cells it makes energy. This energy is turned into electricity for your home. PV panels are better now than before. They are more efficient longer and are cheaper.
