Photovoltaic
Solar modules transform the Sun’s energy into clean, continuous electricity.
A photovoltaic installation aims to produce electrical energy from the Sun’s energy. This electricity generation, without the emission of pollutants, is produced as a result of capturing solar energy and directly transforming it into direct current electrical energy, as a result of an internal physical process in the solar modules called the photovoltaic effect.
The photovoltaic cells that make up photovoltaic solar modules are the devices in which this effect occurs. The electrical energy generated in the modules is direct current. To transform it into alternating current suitable for injection into the distribution network, it must pass through an electronic device called a grid connection inverter.
Grid-connected inverters guarantee the quality of the electrical energy fed into the distribution grid, so that electricity companies and grid users do not experience distribution problems as a result of this electrical input.
Advantages of integrating photovoltaic systems
GENERATION
Clean, distributed electricity generation, close to consumption sites and prioritised in accordance with Royal Decree 661/07, which seeks to fulfil the environmental commitments made by the State and make better use of our own resources, such as the sun.
OBTAINING
Obtaining a better rating in obtaining the necessary energy efficiency certificates, in accordance with RD 47/0.
COMPLIANCE
Compliance with the Technical Building Code, which provides for the incorporation of photovoltaic electricity into the general electricity grid in Annex HE 05 for certain types of buildings, or the replacement of part of the domestic hot water supply provided for in Annex HE 04.
ALLOCATION
Provide the building with a distinctive and innovative envelope that makes it aesthetically iconic, within a new urban development or integrated into an existing one.
Wind energy
Wind turbines harness wind energy to generate electricity using efficient horizontal technology.
Wind energy is a type of renewable energy that harnesses the kinetic energy of the wind to generate electricity using wind turbines, which transform that energy into mechanical energy and then into electrical energy.
A wind turbine converts wind energy into mechanical energy through the rotation of its blades, and that mechanical energy is transmitted through a gearbox so that the alternator can generate electrical energy.
INFORMATION
In Spain, three main types of wind power generation technology are used:
• Asynchronous generator with squirrel cage rotor
• Asynchronous generator with double winding
• Synchronous generator (better suited to the grid, although more expensive)
Low-power wind power
Low-power wind power can be divided into two subcategories:
• ≤ 10 kW — domestic, commercial and agricultural applications
• 10–100 kW — industrial applications
Advantages
• Produces no CO₂ emissions.
• Takes up little space and leaves room for other land uses.
• Electricity generation close to the point of consumption, reducing grid losses.
• Provides electricity in remote areas.
