Components of a solar panel installation
Self-consumption photovoltaic installations have multiple components that make their correct operation possible, such as solar panels, photovoltaic batteries, or current inverters. Below, we briefly explain the importance of each of them.
Solar panels, also known as photovoltaic modules, are components that are composed of a set of solar cells that allow them to transform solar radiation into electricity. There are three types of solar panels that are defined by the manufacture of the cells that compose them, and they are crystalline silicon (monocrystalline and polycrystalline) and amorphous.
The solar inverter is responsible for converting direct current (energy produced by photovoltaic modules) into alternating current. It is an indispensable element in any photovoltaic installation, whether grid connection or isolated installations. There are several types of inverters that are classified according to whether your installation is connected to the electricity grid or is an isolated installation.
Solar batteries are devices that allow us to store the energy we generate through solar panels to make use of it on rainy or cloudy days when the plates are not in operation. The installation of batteries will be essential in installations not connected to the grid and connected to the network if you have large consumption during the night hours.
The bidirectional meter is the device that accounts for the energy that flows from the electricity grid to the consumer (like any other meter), but also accounts for the energy that the consumer injects into the electricity grid. This element is essential in any self-consumption installation with surpluses, since the marketer will compensate you for your energy surpluses, that is, for the energy produced and not consumed that you have poured into the network.
The charge controller is an element of utmost importance since it is responsible for the installation with batteries to work properly. This component has the function of preventing situations of charging and over-discharging the batteries, extending their useful life, as well as ensuring that there is enough power supply in the battery to prevent them from discharging. There are two types of regulators: MPPT and PWM, the choice of one or the other will depend on how your solar installation is and the use you are going to make of it.
The monitoring system is an application that allows the user to verify the proper functioning of their photovoltaic installation in real time remotely and optimize our self-consumption installation. The objective of this system is that the user acts quickly if faults and / or breakdowns are detected in the system and therefore, it is necessary to carry out a repair of it.
Structures and supports
The structures and supports are devices that allow you to place the solar panels on the roof and be able to get the most out of your installation. They are usually classified into fixed and mobile and are usually made of very resistant materials to withstand the wear and tear of adverse weather conditions (torrential rains, snow, strong winds, etc.).
