Installation of the beta product
Thanks to its 13 DualSun panels, the owner now produces 60% of his hot water and all of his electricity since 2013.
Mr and Mrs Martel were initially considering the use of solar energy as an ecological approach. When they arrived in their new home, they already had in mind that their next investment would be in renewable energy. However, they did not have any firm ideas about what type of energy to choose. In the end it was solar energy that motivated them for a variety of reasons, including the fact that it offered an attractive return on their investment.
When their project began to take shape more clearly in the summer of 2011, they opted for the grid connection. The feed-in tariff was even more attractive than in 2019. However, if they had to start from scratch today, they would rather move towards photovoltaic self-consumption of electricity. This is because they feel a little frustrated about not using the energy they have produced. The fact that with DualSun they can self consume their thermal hot water produced by the panels partly consoles them.
Energy and economic advantage
Thanks to its high efficiency, the return on investment will be divided by 3 compared to a conventional solar thermal system.
On electricity, the DualSun produces up to 3600 kWh/year, i.e. 100% of the average annual consumption of a household (excluding heating). The feed-in tariff for photovoltaic energy will allow the user to balance his expenses.
On hot water, the DualSun provides up to 65% of the sanitary needs, which will lighten the individual’s bill and allow him to use the heat in other ways… by heating his swimming pool for example.
