Climate catastrophe hits photo voltaic in southern Brazil – pv journal International


Heavy rains lately prompted flooding in Brazil’s Rio Grande do Sul state when Lake Guaíba and the Taquari River and Uruguay River overflowed, reaching greater than 5.30 meters and affecting greater than 1.95 million individuals. The loss of life toll stands at 143, with 125 lacking. The authorities haven’t but assessed the losses of the submerged or affected PV vegetation.

Mara Schwengber, coordinator of the Brazilian Association of Photovoltaic Solar Energy (Absolar) in Rio Grande do Sul and the CEO of Solled Energia, additionally organized a fundraiser to assist flood victims.

“As the G5 unfold all through the nation, within the first few days we had been in a position to elevate monetary assets to purchase issues like water, meals, biscuits, cleansing supplies and fundamental hygiene,” Schwengber mentioned. . “As a consequence, we managed to get many individuals to take part and we now have already organized the donation of 100 double mattresses to native corporations, which someway must proceed their actions, along with a a big bundle of blankets coming from São Paulo and destined for the victims.”

Schwengber mentioned that Absolar continues to be not in a position to assess the injury to the PV methods within the state as a result of the victims are a precedence and since the water has to recede to entry these places. “Life is the precedence now and we should do all the pieces to cut back struggling,” he added.

The challenge coordinator and database administrator of Yes Energia, Leandro Pandolfo, mentioned he began to create a flood influence map primarily based on preliminary mapping knowledge from the Hydraulic Research Institute (IPH).

“In the mapped flooded areas, we apply the layer with the precise location of the methods put in by Yes Energia. This method we are able to establish these affected by the situation and the know-how put in. With prospects who filtered by the producer and know-how, we began the method of checking alerts by means of our personal system referred to as Yes Assist and the producer’s devoted monitoring platform,” mentioned Pandolfo.

“We noticed the injury that was taking place inside the home,” mentioned the co-founder of Yes Energia, Tiago Fernandes. “Those affected by the flood are our associates, colleagues and prospects. Given these information, our business and administrative groups have began working remotely, whereas technical groups are primarily centered on emergencies. We put in place an motion plan, which consists of three key steps: evaluation and assortment of data; contact with enterprise companions; and restoration of amenities and infrastructure.”

However, there’s a massive distinction by way of safety in these two fashions, he added.

“The modules might be powered whereas the solar is shining, even when the system isn’t producing energy,” Spohr mentioned. “In string methods, the circuits that come from the roof have excessive electrical voltage, which creates dangers in these conditions. In SolarEdge methods, there are optimizers related to the modules, which have a function referred to as Rapid Shutdown, a fast shutdown mechanism that reduces the voltage degree to nearly zero, decreasing the potential hazard of the flooded space.

Even with inverters outfitted with the know-how, Spohr mentioned most prospects shouldn’t have insurance coverage for photo voltaic power methods.

“We proceed to contact the producers in order that they will activate the analysis of the broken tools, but when vital, we are going to accumulate this whole tools base and ship it to an organization specialised in electronics to attempt to recuperate the inverters,” he mentioned. . “However, if that is performed, we all know that we are going to lose ensures sooner or later.”

“From the photographs we acquired this week, it’s potential to see that these first homes which have their methods affected are easy homes, the place households have misplaced all the pieces they’ve, private paperwork, furnishings, home equipment, garments, and typically the home itself was taken away from the flood,” mentioned Filho.
