Train a group of experts capable of promoting both

high level research and local industrial development

by means of setting up pilot photovoltaicconcentration plants.

To become a centre of reference that provides reliable

information to the entire world on the power and

productivity of commercial CPV systems.

O&M issues

Module issues: Very few modules found with minorissues generally not affecting production

33

SOLVED IN THE PRESENT COMERTIAL GENERATION


34/49

O&M issues

Conclusions- Most of the Operation failures come from thetrackers- Many failures can be solved after reparation

- Qualification tests needed to avoid thetrackers failures- Very few failures in modules, which can besolved with the experience in demonstrationplants

Degradation study

- Almost the same slope in the 3 years => No visible degradation- Performance depending of the DNI

tracked PV between the months of January 2010 and July 2010CONFIDENTIAL


39/49

CPV vs PV

Conclusions

- Very similar production level between CPV andtracked PV systems in Puertollano, which is a

medium sunny region, with the CPV rated at 850W/m2

- Fix PV has always less production than CPVand tracked PV systems

- Much better production of CPV in very sunnymonths

43/49

Other advantages

Production during the peak demand

43


44/49

Biggest advantages

Performance

- Better performance than PV in sunny and hotcountries

- Better efficiency => Less number of modules,trackers and land

- Production during the whole day- Lower degradation (to be demonstrated)
