Hybrid photo voltaic panels produce each sizzling water and electrical energy. Dearer than typical photovoltaics, this know-how remains to be not unanimous amongst people. However what’s it actually price? Testimony of a person who has chosen to put in it on his roof.

For fifteen years, Pierre André has been drawing a part of his vitality wants from the solar. This resident of the Rhône had 3 thermal photo voltaic collectors from the producer Giordano, which solely equipped him with home sizzling water. He changed them in April 2022 with a hybrid energy plant, able to producing electrical energy concurrently sizzling water.

With an influence of 6 kWp, its new set up is made up of 12 “Flash” photovoltaic panels and 4 “Spring” hybrid panels designed by DualSun. The plant is positioned on its roof with a really favorable orientation, dealing with south and 27 levels of inclination. An funding that price him €17,400 set up includedfinanced by a credit score throughout the framework of an general renovation of the dwelling. However for what consequence?

100% photo voltaic showers in summer time

This retired pc engineer claims that the hybrid panels coated 100% of his home sizzling water wants through the summer time. He notes, nevertheless, that he has to “add somewhat electrical backup through the day” at its cumulus of 300 liters since mid-September, the climate being much less and fewer favorable as autumn approaches. A complement with out a lot consequence on its vitality stability, since it’s offered by the photovoltaic a part of its energy plant.

Giordano panels had been far more environment friendly [pour produire de l’eau chaude, NDLR]they heated to 90°C. There, the hybrid panels are voluntarily restricted to round fifty levels in order to not penalize the photovoltaic yield” he concedes. If its outdated thermal sensors assured it extra sizzling water through the shoulder seasonsit’ll now should eat somewhat extra electrical energy to compensate for the warmth loss over this era.

Pierre André confides that he doesn’t remorse this substitute, as a result of in any case, “in the midst of winter, the thermal panels give nothing, zero! » he assures. Whether or not solely thermal or hybrid, these collectors would produce little or no sizzling water through the chilly season for this Rhone resident. A phenomenon that’s nevertheless very depending on the kind of set up and geographical location, with some individuals managing to acquire enough warmth from thermal collectors in winter.

Recharge your electrical automobile with photovoltaics

The pensioner depends primarily on the electrical energy produced by his energy plant, which basically permits him to recharge his Volkswagen ID.3. Its panels would have produced 40 kWh day by day in July and August. It’s a little much less in Might, with a complete of 994 kWh (or 32 kWh/day).

“For the second, I handle to realize somewhat greater than 50% self-consumption, as a result of I have not optimized it but” he explains. His electrical automobile already ranks excessive on this fee. It’s largely fed with photo voltaic vitality, because of “a ten A charger, which prices slowly, however permits me to by no means exceed the manufacturing of the photovoltaic panels” he specifies.

Thus, in the summertime, the ex-engineer recharges “between 11 a.m. and 5 p.m., i.e. for six hours”. It recovers approx. 14 kWh each sunny daywhich might suffice for his quick city journeys. “In case of better want or lack of solar, I full the night time with a wallbox that prices at 32 A and one night time is sufficient to cost the EV, which has a 52 kWh battery, to 100%” he particulars.

Automation to optimize self-consumption

Pierre André plans to put in automatisms to be able to improve his fee of self-consumption. These units will make it potential to activate and off the facility provide of sure tools in accordance with photo voltaic manufacturing, with out handbook intervention. He needs to make them with the assistance of different fanatics who focus on on a discussion board specializing in photo voltaic.

As a result of, if he resells the unconsumed electrical energy injected into the community for €0.10/kWh, he should in parallel purchase it at the next fee. It’s subsequently extra fascinating to make use of one’s personal photo voltaic manufacturing.

Sadly, installers and producers of solar energy vegetation not often inform their prospects about methods to advertise self-consumption with out having to plan every part manually. Solely essentially the most skilled people set up on their very own relays and different linked sockets to modify on power-hungry home equipment when the solar shines at its strongest.
