What it is and how a photovoltaic system works?

A photovoltaic system is a device that takes solar radiation to produce electricity in a way that can be exploited by man. The system consists of the following elements (see diagram):

-A solar array, which consists of a set of photovoltaic panels, which capture light radiation from the sun and transforms it into direct current at low voltage (12 or 24 V).

- An accumulator, which stores energy produced by the generator for outside daylight hours or cloudy days.

- A regulatory burden, whose mission is to prevent overloading or excessive discharges to the tank; And to ensure that the system works always at the point of maximum efficiency.

- An investor (optional), which transforms the direct current of 12 or 24 V stored in the accumulator, in alternating current of 230 V. A solar photovoltaic inverter without, use 12Vcc A solar photovoltaic inverter with, use 230Vca

Once the electrical energy is stored in the tank, there are two options: to draw a line directly from the latter for the installation and use lamps and elements of consumption of 12 or 24 VDC (first schedule) or to transform the DC current in alternating 230 V to through an investor (second schedule). If instead of a solar panel a wind turbine is installed the system is called wind.

If both are installed will be a mixed system. In this case, each must bear its own regulator. Learn how to build more with solar energy.
