Troubleshooting Photovoltaic Installations: Ensuring Meter Reversal Benefits in Wallonia

“Me and my neighbours, we don’t consume all the electricity we produce. So we put it back in part on the network, he explains. But since it can’t absorb everything, the production of our solar panels is cut off.”

Photovoltaic in Wallonia: will the installations reinforced in 2024 lose the benefit of the meter running backwards?

The problems started in August 2022. “At first it was once in a while. It was still fine. But since the return of the good weather, it happens all the time.”

He therefore goes from a situation in which he was more than self-sufficient in electricity (since he put it back on the network) to a situation in which he must buy electricity from the network since his solar panels are regularly “out of order “.

In short, Pierre Delatte finds himself in a rather unfortunate situation and, according to his calculations, he should lose several thousand euros. “And what’s more, the voltage at the sockets is much too high. Today (Editor’s note: Wednesday), it was 269 and normally it should be 230.” Race results: “I regularly have light bulbs that burn out and the household appliances will be damaged”.

And in the meantime, Resa, the network manager, is slow to intervene. “I contacted them several times, the first on May 9, and each time I am told that my request has been registered and that we will intervene. But I still haven’t seen anything coming. I will take a lawyer if the situation does not evolve.”

A counter to analyze the situation

But normally, Pierre Delatte should not wait too long. “We will intervene next week, says Charlotte Quevedo, Resa’s press officer. Given the number of requests, we try to group the interventions by street. This explains some waiting times.

And next week, “We will intervene at the level of the suite cabin near Mr. Delatte. We will also offer him the installation of a sophisticated meter which will allow the situation at his home to be analyzed”.

And depending on the results provided by the counter, the various possible actions will be considered. “We can, for example, rebalance the phases.” And if that’s not enough, Resa will invest in the network. “It is certain that we will have to adapt it to certain places. Basically, it was designed to distribute electricity, not to receive it.”
