Do I need to inform our local Electric company before I connect or I can just tap my system to the existing power line? What equipments do I need to adjust to the supply voltage of our power provider?

Utilites do require you to inform them of your intentions to connect to their service grid. This is so that they can properly meter your service usage and your PV production to give you credit when you feed back into the grid. In many case this requires an interconnection agreement between you and your utlity and they will often have to replace your existing meter. If it is not bi-directional, you would not be able to receive credit for any excess energy your system is able to put into the grid.
The primary electrical elements that you would need are the PV modules and a grid-tied inverter. Secondary equipment may include a combiner box for combining multiple PV circuits into the inverter, a DC disconnect to isolate the PV from the Inverter for maintenance, an AC disconnect to isolate the PV inverter from the service panel & grid.
