Those who want to be self-producer of electricity, that is if you want to produce the electricity it consumes can be done by installing a solar panel system.
It is a set of technological systems through which the solar radiation incident on the photovoltaic module is converted into electrical energy.
The key elements of the system are obviously:
Photovoltaic modules: Made from silicon cells (mono – poly – multi -crystalline) which capture the incident solar radiation and by means of a thermo-chemical process to “transform” into electrical current. The photovoltaic modules are then the current generators of plant (generally from 30 to 40 V to the current of 6 – 10 A). To ensure that most photovoltaic modules contribute to simultaneously produce energy and direct it to plant they are connected in a “string” (ie in series and/or in parallel to the series).
Inverter: An electronic device that converts the energy from PV modules (then current) into energy suitable to be used in our homes and be fed into the grid . The electricity of the modules not in fact has the same characteristics of that which is normally available in the home. If the solar panel system is large the task of transforming the electricity will be assigned to multiple drives.
Electrical Components Accessories: In addition to the PV modules and all inverter ‘s plant consists of a number of accessories that complement it with regard to security and functionality: surge arresters, disconnecting the AC and DC side, RCBOs, etc.
Mounting structures ad hoc, data logger, energy meters complement what, at this point, we can define “Solar Panel System”.
