RENEWABLE ENERGY


PHOTOVOLTAIC SOLAR POWER

- Isolated Installations:

At installations isolated from the grid, you can produce your own energy without cost and without damaging the environment unlike being connected to the grid or depending entirely on a generator.

A basic system that is isolated from the grid consists of a DC renewable energy source, a set of batteries to store the energy and an inverter/charger. The inverter is the intelligent centre of a renewable energy system, which perfectly converts the electrical power generated as DC, to clean AC power that is ready to be used.

With a back-up system, homes connected to the grid can benefit from having electricity available even when the grid fails. An inverter/charger automatically detects the failure and instantly switches to use the power that is stored in the battery pack.

- Grid installations:

The aim of connecting a photovoltaic installation to the grid is to be able to sell back all the power that is produced so that the clean energy that is consumed from the grid is progressively increased.

By connecting a photovoltaic installation to the conventional electrical grid we are able to turn the installation into a small production plant. This way part of the energy that is consumed by users will originate from renewable sources.

PHOTOVOLTAIC THERMAL ENERGY

Cadielsa along with its thermal photovoltaic energy suppliers, which are companies committed with manufacturing environmentally safe products, are committed to making a rational use of the energy provided by nature. Of all these energies, solar power stands out for being an energy that is clean, free and endless, and capable of easily and efficiently providing a high percentage of Domestic Hot Water for consumption.

Some time ago, Spain decided to take the lead in Europe in taking advantage of this energy. This resulted in many municipal regulations being issued which required using these types of installations as well as many local as well as national subsidy programmes.

New solutions are being introduced on the market to adapt boilers and heaters to solar thermal energy installations as well as a wide range of specific products for these systems (collectors, tanks, hydraulic sets, ...etc.).

WIND ENERGY

Wind energy is a type of renewable energy that is powered by the wind. The typical way of taking advantage of this type of energy is by using wind generators or turbines.

How do we produce electricity from wind? The direct predecessor of the current wind generators are the old windmills, which even today are still being used for extracting water or milling grain.

A windmill has rotor blades connected to a common shaft, which begins turning when the wind blows. This rotating shaft is connected to different types of machinery like for example machinery for milling grain, pumping water or producing electricity.

To produce electricity, the movement of the blades or vanes will in turn move an electrical generator that converts mechanical rotating energy into electrical power. The electricity may be stored using batteries or it may be directly input into the grid. The operation is very simple and what becomes more complex is the construction of wind generators that are increasingly more efficient.

GEOTHERMAL ENERGY

The subsoil maintains a constant temperature throughout the year regardless of whether it is snowing or sunny above ground. To take advantage of this circumstance we can install a thermal heat pump.

Heat pumps are highly efficient devices and do not use the energy they consume to produce heat like in the case of boilers; instead, they transfer heat from one location to another as required and therefore are much more efficient than combustion systems.


BIOMASS

- Boiler with a manual and an automatic operation:

• Boiler with an automatic operation for: Fuels, solids such as pellets, almond shells, marc, olive seed, ...etc.

  • • Electronic system for controlling the boiler and the easy to use heating circuit, includes control of the power supply.

  • • Cast iron body by elements which favours a longer service life by considerably reducing the damages caused by condensation.

  • • Fuel tank with the possibility of installing it on both sides of the boiler, a large capacity (750 litres) for a long uninterrupted operation.

  • • Easy operation and with minimal maintenance.

  • • The internal design of the boiler body ensures a large amount of heat will be exchanged between the combustion gases and the water and provides a high performance.

  • • They meet the requirements of standard 303/5. Special heating boilers for solid fuels.

  • • Low emissions with a minimum impact to the environment.

  • • The ashes of combustion are deposited on the bottom part of the boiler where they are collected in a large capacity tray that is easy to remove.

  • • Working pressure of 4 bar.

  • • High performance, (more than 85%), verified through certified measurements.

  • • Low CO2 emissions (below 200 mg/m3), low dust emissions (below 150 mg/m3 at full load).

  • • Continuous modulation of the output power, (not only regularisation by connection / disconnection since this causes emissions and high losses).

  • • High degree of automation to reduce the required maintenance.

  • • Possibility of remote control with the parameters of the boiler through the supplier.


AEROTHERMAL ENERGY

Aerothermal energy consists of taking advantage of the energy contained in the air that surrounds us. This is accomplished using aerothermal heat pumps for heating and domestic hot water systems. Aerothermal energy is an alternative to conventional heating systems.
 
The total cost of using aerothermal energy is one of the lowest that exist for heating due to its excellent energy efficiency and notably contributes to reducing CO2 emissions.
 
Some systems only use heat pumps and others called hybrid, take advantage of other sources of energy that already exist in the installation such as gas or diesel, thus optimizing the cost of energy even further.
 
Because it is classified as a highly efficient energy, Aerothermal energy is considered a renewable energy and on occasions it is even able to obtain official subsidies.
