A job in solar energy

[Blueeyes]

Hi I'm new to the forum.
I am from Romania and I entered a faculty of electrical energy from me in the country.
In the future I would like to work in the field of solar energy, but I have some questions about field.

1.) I would like to become a specialist in the maintenance of a photovoltaic park.
2.) How does a photovoltaic panel work, could you give me some materials or videous with that? (I would like with videous where a person explains the physics and mathematics of the photovoltaic panel).
3.) Do you have to have deep mathematical knowledge for this or not?
Thank you and I'm waiting for answers.

3.) Do you have to have deep mathematical knowledge for this or not?

Not for maintenance or install, no.
Not even for designing large scale systems, basic engineering math would be all that's needed.

Just put the panels on rooftops and not on roadways, and you should be fine

For design, installation and maintenance of actual solar installations you don't need much physics, all though it is nice to know a few things--perhaps to understand issues like why solar cells become less efficient when hot.  However, what you actually need to know are:

1) Mechanical engineering and building codes.  The hardest thing about solar installations is getting them approved and making sure they don't fall down or blow away--or get run over by trucks. 

2) Basic electrical theory and electrical building codes at the level of a journeyman (experienced) electrician or so.  While the circuits themselves are dead simple, the safety code requirements can be extensive.

The theoretical aspects are all taken care of by the product manufacturers,  you just have to be able to understand their datasheets and installation requirements.
