As reported by Red Electrica, around 11:00 this morning, the 100% of the electricity demand peninsular. It has been almost 24 hours since the great blackout occurred and although practically all the problems have already been paid, we cannot say that everything has returned to normal.
Depending on the place where you were, and the measures and resources that the place had, Internet and light connection could last more or less. This is because many homes and businesses They had batteries and extra light generators that allowed to have electricity when the general systems stopped giving it.
Searches for this type of products multiplied during the first hours of the blackout, and there were many who asked or even envied those people who had solar panels in their homes.
However, the truth is that Despite having photovoltaic plate systems, many buildings and houses suffered the same as the rest said blackout.
The reason why solar panels were not enough to overcome the blackout
The reason why many of the houses with solar panels were not saved from the large blackout is due to how Most solar systems connected to the network are designed to function for security reasons.
This is because the vast majority of residential solar panel systems They are connected to the public electricity grid. This allows owners andnviar the excess solar energy back to the network (often receiving credits) and taking energy from the network when its solar production is insufficientas at night or in cloudy days.
In turn, and for security measures, during an energy cut, the immense These systems are automatically turned off To prevent solar panels from sending electricity back to the network While the workers of the electric company are trying to repair the lines.
The only two ways to have electricity with solar panels during a blackout
Solar panels can provide energy during a blackout, but only if the house has one of the following options:
- An isolated solar system (OFF-GRID): These systems are not connected to the public network at all and depend solely on solar energy, usually combined with battery storage.
- A system connected to the network with backup battery and “isolation” (Islanding) capacity: Some advanced solar systems include batteries and investors that can automatically disconnect the network house during a blackout YCRear a self -sufficient “island”, using the battery -stored energy and any electricity that are generating the panels.
