What are the components to expect when you buy a complete solar system?

[Min George]

Solar systems are becoming more common in usage nowadays. When one purchases a complete solar system, what are the components that are expected to come with it? And what is the use of each of the components in the working of the solar system?

I think it often involves a solar panel, the inverter, a charge control and the batteries, these should be the things found when you buy a solar system.

There must be a battery and a solar panel. There is also an inverter. The bonus is that it might have a free led bulb.
