Who are we?

In October 2020, sunthalpy created the first building 100% solar/disconnected from the electricity grid, in any region of the world with an Atlantic climate thanks to its low enthalpy solar technology. After almost three years of intense development, we have compacted that technology and today we are already turning poorly insulated old buildings into positive ones, reducing their energy costs by more than 90%, while radically improving their comfort.

We are able to face the challenge of energy efficiency in buildings and business facilities of any type and size.

Since its launch, we have not stopped reaping successes in the business sphere, such as the one achieved recently, with the conversion of a 21-year-old Class E building into a Net Zero (positive annual balance), without the need to modify the original facade, among others.

With sunthalpower and sunthaldress, the most advanced technology on the market, you will cover the energy and air conditioning needs of your organization with unparalleled levels of optimization.

What does it mean?

sunthalpy is an abbreviation of the English sun and enthalpy. Enthalpy, enthalpy in Spanish, we can say in a simplified way that it is a form of energy. For us, sunthalpy is the realization of a utopian world in which we can enjoy technological development to the fullest but in total harmony with the environment, so that our environmental impact is zero. Satisfy all our energy needs using the sun as the only resource, the origin of all clean energies.






sunthalpy engineering is born, the construction of the only house in an Atlantic climate completely disconnected from any energy source begins.
