What types of photovoltaic installations exist?

In today’s article we will learn more about the types of solar photovoltaic installations and the differences between them; so it will be easier to know which installation is the one that best suits your needs.

First of all it is important to know what a solar photovoltaic kit is. A solar kit is the total of components that allows a solar installation to function as an energy collector. There are many variants and additions depending on each case, but in general features should be known: solar panels, solar inverter, charge controller and batteries.

Types of photovoltaic solar installations

Isolated solar installation: An isolated solar kit allows the supply of energy in those homes or buildings where there is no access to the electricity network, you do not have a contract with the electricity company, or you want the disconnection of the same voluntarily.

These kits consist mainly of: Solar panels, a charge controller, an isolated inverter and batteries to store energy and use it at night or on cloudy days.

Installation of network connection: Also called direct self-consumption, a network connection kit is one that is prepared to be installed in homes, buildings or any infrastructure where there is supply of the electric company. The aim is to reduce the energy consumption of the grid and save on the electricity bill, thanks to the production that the solar panels can provide.

These kits are mainly composed of solar panels and a grid connection inverter.

Differences between isolated and network

The main difference between isolated solar kits and grid connection kits is that the inverters of the former are able to generate their own grid for home consumption from only the elements of the solar kit. In some cases of homes isolated from the grid, the only solution besides photovoltaic would be to install a gasoline generator, which is more expensive and polluting. On the other hand, in the grid connection kits, the inverters use that same grid and simply synchronize to supply the current produced by the solar panels to the consumption.

There are other cases of systems that can combine elements of isolated and grid installations, such as self-consumption with batteries, for which a hybrid inverter would be required.
