Objective
The main objective of this project is, at the European level, to demonstrate the advantages of an innovative grid connected photovoltaic (PV) installation, which offers an optimal solution to the following problems in the present energy supply structure :
- low energy efficiency due to losses in transport
- low energy efficiency due to losses in transformation processes
- institutional barriers to using purer technology
This solution will serve as a model for further diffusion of grid connected PV systems in Spain and in other European countries.
Has been determinated that the energy consumption of the Health Centre in Arnoia, where the solar system was installed, will always be more than the maximal theorical capacity of the Solar Generator production.
A delay in the Monitoring phase was made when connecting the line phone. It was due to the Spanish Phone Company (Telefonica). Nowadays the modem connection for the data acquisition equipment and the monitoring is concluded.
1. Innovative technology and context :
The main innovation of the project is found in the way the electricity is supplied to the local grid in low tension resulting in minimal losses from transformation and transport. The installation has been put in place and directly connected to the local grid with no adaptation necessary in it. As the electricity distribution corresponds with the local authority, who is a co-proposer of this project, no changes in normal procedures in the electricity distribution has been needed.
The production will serve as a supplement to the electricity bought and transformed by the electricity distributor, and as such a larger generator could be installed in the future. However, for demonstration purposes, and for generating the positive influence in the local society, a 25 kWp installation is sufficiently large to demonstrate the integration. 2. Economic aspects :
Expected annual production :25 kW x 1630 peak solar hours per year = 29150 kWh/y.
In 1994, Ayto. de Arnoia bought 1294 MWh from Union-Fernosa and paid 12955000 PTA. Ayto. de Arnoia estimates losses in transformation of 82 MWh and a study done by Albasolar says 97 MWh. This gives an effective price after transformation of 10,7 PTA/kWh.
The effective price of electricity paid by the end-users in Ayto. de Arnoia was approximately 28PTA. A prudent estimation of the real cost by Ayto.de Arnoia (taking into account the depreciation of transformers and the cost of maintenance and operation) is 14 PTA/kWh. The minimum monetary value of the energy produced will therefore be : E= 14PTA x 29150 kWh/y = 408100PTA/Y
The expected pay-back is 119,7 years.
