To calculate the profitability of an installation, what assumptions are taken into account?

DualSun takes into account certain assumptions in calculating the profitability of an installation. Our sizing software MyDualSun provides economic information based on a self-consumption installation configuration, i.e. all energy produced is consumed within the household with the DualSun installation.

The savings generated by a DualSun installation are calculated from energy prices: the photovoltaic electricity produced is valued at the price of electricity in peak hours; the solar domestic hot water produced is valued at the price of electricity in off-peak hours (since the water tank is heated during off-peak hours).

We also take into account the assumption that energy prices will increase.
