What's on the roofs of houses in Cyprus? We explain what tanks and panels are for.

First-time visitors to Cyprus often notice the distinctive rooftops. Most buildings feature a large white tank and panels next to it.

For the island's inhabitants, it's a completely normal part of the landscape. However, for tourists and those moving to Cyprus, it can be a mystery.

The white tank is the water supply

The large white tank on the roof is used to store domestic water.

Although water supplies in Cyprus are much more stable today than they were decades ago, tanks are still installed in almost every home and many apartment buildings. They act as a water reserve in the event of a power outage and help maintain adequate pressure in the system.

There is a solar heater next to it

The second characteristic element is the solar panels intended for not for electricity production, but for heating water.

Solar radiation heats the water circulating in the collectors, which then flows into a well-insulated tank. This provides residents with hot water for most of the year, with virtually no electricity costs.

Why is this system so popular?

Cyprus is one of the sunniest countries in Europe, making solar energy for water heating exceptionally cost-effective.

It is estimated that over 90 percent of households on the island use solar water heaters, one of the highest rates in the world.

What about in winter or on cloudy days?

Most installations are also equipped with an electric heater.

If there's not enough sun, simply turn on the electric heating. In many homes, this is done with a distinctive switch located in the kitchen or hallway. After a few or several dozen minutes, the water reaches the desired temperature.

It's worth knowing

The solar panels seen on the roofs of Cypriot houses are the most common solar collectors for water heating, not photovoltaic panels that produce electricity. Although they may look similar from a distance, they serve a completely different function.

Do you need to worry about this?

No. If you rent an apartment or buy a house in Cyprus, the entire system works automatically and requires no daily maintenance.

It's just worth remembering to periodically service the system and check that the electric heater is working properly. This will ensure there's no shortage of hot water even in winter.

For many people moving to Cyprus, the sight of rooftop tanks may initially seem unusual. However, after a few weeks, it turns out to be one of the most practical and economical solutions used on the island.
