Abstract

The aim of the present work was to find out the feasibility of low-cost support structures for large PV generators (20-25 ECU/sq.m. This contract was executed by Colpizzi Company who was in charge of the study of the site and of the soil; the company was also in charge of the study of materials involved in the construction of the plant, of the site preparation, of the material component parts, supply, of the erection of the plant and of the fitting of PV panels. Universities of Florence and Pisa gave their contribution for the design of the structures and assistance in site. The plant was completed in cooperation with ENEL-CRITA- ISMES institutions as main contractors of a parallel study-contract with the Commission (Contract no ESC/R/092/I (S)). A unit of about 200 modules was erected in the site of Castellina in Chianti and the results of such experience was reported here. As far as the site selection is concerned, well exposed position, gentle degree of slope to reduce severe soil erosion by water, sufficient depth of stoneless soil, were chosen. The mechanical composition of soil was taken into account as another important aspect of the site. Drainage of soil was also considered necessary. On this site, light, continuous reticular systems utilizing wood and steel wires (as main structural materials similar in modern vineyard support structures) were erected. The solutions were developed within the above mentioned limits of 20-25 ECU/sq.m. costs. Real final costs were very close to the estimated costs. An economical and technical analysis of the project was set up to demonstrate the feasibility of such structures and to decide whether or not the solutions were suitable for large scale exploitation.
