JRC-European Solar Test Installation (ESTI)
- Research Infrastucture for the development of energy yield and rating methods for emerging PV technologies
MAIN FEATURES :
The European Solar Test Installation (ESTI) is a European reference laboratory for the verification of the power and energy generation of photovoltaic devices. ESTI is located at the JRC's Ispra site in Italy. It has been at the forefront of developing standards for electrical performance of PV products since its launch in the late 1970s. ESTI's work supports the EU's renewable energy policy (Directive 2009/28/EC)
- Concerning energy yield and energy rating, ESTI’s approach uses:
- solar radiation and temperature data, as modelled in the geographical information system PVGIS,
- a "performance surface" model for the conversion efficiency of specific PV module types, with the module temperature and incident irradiance as independent variables.
The energy yield models are also implemented in the JRC PV-GIS system to provide location-specific yield estimates in Europe and Africa.
The experimental facilities include a dedicated module test stand with high frequency monitoring of performance data and I-V characteristics.
ESTI staff have been at the forefront of this area for several years, in the Performance projects and in IEC TC-82's WG2, which is developing the IEC 61853 energy rating standard.
