Five 200watt solar panels for a period of one hour will create one kWh. So, one 200 watt panel will create 0.2 kWh of electricity

It all depends on the size
It depends on the model, please specify.
Technically it can have any number of cells.
Probably because a solar panel can produce electricity for many years.
There are many ways one can build a solar panel. One can build a solar panel by making a template for solar cells, putting a frame together, and sanding the whole thing down.
One solar panel is 250w
Genrally speaking five 200 watt modules will make a 1kW DC solar electric generator. There are many solar module manufacturers and many sizes and shapes. However the 200Watt range appears to be a constant due to the size and weight of the module as it applies to OSHA installation requirements.
The same as it can generate in a day, or in a year, or in a second. Kilowatt is a unit of power, not a unit of energy.

I did not locate a solar panel laptop itself, but there are solar panel laptop charger for the laptop battery. these will last many years and substitute for buying a laptop battery every year.
Well... Could it be a Solar panel?

A company that will sell you solar panel cells and other materials need to build your very own solar panel is EverBright Solar. (this is only one company that sells solar panel material, there may be many more)
The power listed on the solar panel presumably is the peak power. This power is the maximal power outup of the solar panel, which is only reached under ideal solar irradiation conditions. For comparison: a energy efficient computer uses about 150 W .
A solar panel is a large investment. It is also somewhat complicated to install. It would be best to have a professional install the panel. Many companies will install the panel at no charge.
