This hot water tank stores the energy produced by solar panels

Generate electricity using solar panels not only reduces the bill ofenergy but to make a gesture for the Planet. However, during the day when energy needs are lowest, part of the unused electricity production (the surplus) is returned to the network. To eliminate this loss, and increase the share of self-consumption, the most common solution is to install batteries… An efficient but more or less expensive process which requires the use of polluting technologies such as lead open or lithium-ion.

Consume the electricity produced

Based on this observation, the manufacturer of solar panels Systovi innovates, by offering Stock-O. a domestic hot water tank (DHW) of 200 liters capable of store energy, as soon as the installation goes into overproduction. The latter, with a power of 2,000 W, integrates three resistors (250, 500 and 1,250 W). Positioned at different heights, they are requested according to the solar production of the moment until the volume of water contained in the flask is completely at temperature.

Store electricity at no extra cost

An innovative process which makes it possible to store the equivalent of 10 kWh, bringing the share of self-production of electricity to 80% or even more depending on the region. For owners, whose houses are already equipped with photovoltaic panels, the integration of the stock-O DHW tank is quite possible. This comes to replace the old classic electric balloon.

Have a continuous hot water reserve thanks to thesolar energy, can meet the needs of a home of four or even five people, evening and morning. Available from professional installers or specialized brands, this balloon does not currently benefit from financial aid … However, compared to an installation using lithium-ion technology, the manufacturer announces a cost. global divided by four.
