Ecohotel · figures, not adjectives
We do not have a certification plaque to hang on the wall. We have 190 solar panels, a battery bank that supplies energy during the night, and a pool with almost imperceptible chlorine levels. This is what we do: real data, measured and without embellishment.

How the energy gets from the roof to your room
Photovoltaic system
The solar panels cover the building’s rooftops and provide 60 kW of nominal capacity. On a clear day, they produce more energy than the hotel consumes at that time; the surplus is used to charge the battery bank.
Storage
The main battery bank uses lithium technology with lithium iron phosphate (LFP) chemistry and has a capacity of 100 kWh. In addition, we have an older nickel-iron battery bank with a capacity of 144 kWh that is still operational, although it is approaching the end of its useful life. These energy storage systems allow part of the hotel to operate during the night. The 33 air conditioning units serving the 17 accommodation units are powered by this stored energy until the batteries reach their discharge limit. When the hotel has medium occupancy, the stored energy can cover most of the night and may even last until solar generation resumes the following day. However, when the hotel is fully occupied and temperatures are high, consumption increases and the stored energy may be depleted around midnight.
Hot water
The hot water in the bathrooms does not go through an electric element: it is heated by solar panels and stored in three tanks. That is why there is hot water at six in the morning without the hotel spending a watt heating it.
Consumption in the room
All lighting is high-efficiency LED and the air conditioning is inverter. When you leave the unit, a switch cuts the power and leaves only the fridge and one socket for charging devices on. It is only fair to state the trade-off: you cannot leave the air conditioning running to come back to a cool room.
Water
During the rainy season, water collected from the rooftops is stored and reused for toilets and garden irrigation. It is not drinking water and is not intended for consumption; it is water that we use to reduce our reliance on the municipal water supply.The water is stored in an old underground garage located beneath the restaurant and is then pumped into a pressure tank for distribution.
Waste
Organic waste is collected by a hotel staff member and reused as animal feed. Plastic bottles are separated and sent for recycling. At the café, we use reusable tableware instead of disposable products. For guests who wish to take food to eat outside the hotel, we provide compostable cups, containers, and bags.
Pool
The pool uses a high-efficiency filtration system, and copper ions are injected to help prevent algae growth. Chlorine levels remain low and almost imperceptible: less odor, less eye irritation, and fewer chemicals entering the garden.
Because saying “commitment to the planet” can mean many things; 100 kWh, on the other hand, is a concrete and verifiable figure. Any guest can see the solar panels from the roof and the batteries in the machine room. If you would like to learn more, we are happy to show them to you; just ask at reception.
The 70% represents the share of the hotel's consumed energy that comes from the sun during a normal year. The remaining 30% comes from the electrical grid, mainly during cloudy days or periods of high temperatures when air conditioning demand increases.
This figure corresponds to the average recorded during 2025. We measure the energy coming out of the inverters (from the solar panels or the battery bank) and also measure the energy coming in from the public grid, so the calculation is based on real and accurate measurements.
There is also additional savings thanks to the solar thermal panels, as all the hotel's hot water comes from this system. However, it is more difficult to quantify this saving precisely, meaning how much electricity would have been required to heat the same amount of water.
The solar water-heating panels have been operating since the hotel opened in 2013, while the photovoltaic solar panels began operating in 2017. In 2023, we added an additional 10 kW of solar capacity.
Our next goal is to expand the lithium battery bank from 100 kWh to 200 kWh. We would also like to increase the number of solar panels, although we currently have limited available roof space with the appropriate south-facing orientation.
We hold no third-party environmental certification. If we ever obtain one, we will say who issued it and when. In the meantime, this page only states installations that exist and can be seen.
