Photovoltaic installation for self-consumption without storage

MAIN GOAL:


The main goal of this project is to generate electricity for self-consumption without storage at Sotavento’s Experimental Wind Farm.

BACKGROUND:


One of the main reasons for the use of solar energy as electricity production is, in addition to its economic viability, to reduce the environmental impact, as it is an inexhaustible and indigenous energy source.

The use of solar energy contributes to a lower consumption of fossil fuels that increase the greenhouse effect and global warming. Therefore, the use of solar energy reduces the price of electricity and energy dependence on other countries, avoiding the emission of more than 37 tonnes of CO2 per year into the atmosphere, and contributing to the necessary decarbonisation of the planet.

GOALS:


The main goals of this photovoltaic installation project are:

  • The production of electrical energy for self-consumption in the auxiliary services at Sotavento’s Wind Farm, while the surplus is fed into the distribution network.
  • Add a photovoltaic plant to the already existing wind power generation, using two or more renewable sources that share the same connection point.
  • Complement the multiple technical and pedagogical resources in Sotavento, which try to achieve the goals of this installation in the field of energy education.

The development of this installation aims to achieve the best integration between the environment, trying to reduce its visual impact.
