With this case study, we want you to size a solar thermal system for a tourist house in Braga.

The house has five bedrooms: four doubles and one single. This holiday home is inhabited all year round by two caretakers, who serve the house and live in an adjoining room at the back of the house.

With the exception of the months of November, December, January and February, the occupancy rate is $100\%,$ and during these months we only manage to rent out the two double rooms on average.

We also know that the house has an extra consumption of $2000$ liters per month and that the individual consumption per inhabitant should be $70$ liters.

You want to meet the domestic hot water $($DHW$)$ needs of this house, and you need to carry out the following sizing:

$1.$ The collector surface required for the needs in question.

$2.$ The number of collectors at your disposal and, if necessary, the distance between the rows of collectors.

$3.$ The storage volume required and the storage tank chosen.

The panel chosen is from Vulcano, WarmSun $($FKC$-2).$
