Solar Energy

On-grid or off-grid: what changes to the right?

Researching on solar energy systems (or photovoltaic) it can be realized that there are two groups of systems, on-grid and off-grid. In the first, the power generation system is connected to the utility’s grid. In the second, the system is independent and autonomous, you generate and consume your own energy.

What does this mean for law?

In the on-grid system, in addition to the costs with all installation and equipment, you must overcome the regulatory bureaucracy to connect your system to the electricity network and thus be able to enjoy the existing benefits.

This, in Brazil, is regulated by Normative Resolution No. 482 of the National Agency of Electric Energy – ANEEL, of 2012 (regulates the systems of micro and mini distributed). Before the connection, the electric power company must make an inspection and check the quality of the equipment and the installation etc. This is to keep the distribution system safe, as the concessionaire is legally responsible for the service it provides.

On the other hand, in the off-grid, there is no such bureaucracy, but the owner must be aware of the responsibility he has over his system. See, in this case there is no need for the inspection mentioned on the on-grid, but the owner (subject to the supplier’s responsibility) is liable for damages that he causes to third parties.

Assuming an incorrectly installed off-grid system. This system warms to the point of causing a fire to hit neighboring properties. In this case, the system owner can be held responsible for the damage he caused to his neighbors. Not to mention the diseases that poorly conditioned batteries can cause, or even human losses.

Thus, the ease of the off-grid system must be used responsibly, since a poorly installed or low quality system can bring serious legal consequences to the owner of this system.
